Setting the Output Voltage (Cont.) 

Setting the output voltage range

The PCR-LE2 Series has the following output voltage ranges: L and H.

The maximum output current varies depending on the output voltage range. The maximum output current of the H range is half of the maximum output current of the L range.

You can switch between settings when the output is off.

The output cannot be turned on for approximately 0.6 ms after the range is switched (Busy state).

Setting the output voltage

You can set the output voltage while output is on or off. The measured value is always displayed.

Set the voltage limit to prevent the PCR-LE2 Series from generating a voltage that is greater than is necessary.

Be sure to set the output mode (single-phase, three-wire output or two-phase output) before you set the voltage.

The PCR-LE2 Series output impedance is extremely low, so depending on the load, a current may flow even if the voltage is set to 0.0 V. Be sure to turn the output off or turn the POWER switch off when you do not want any current to flow and before you connect a load.

• AC mode

Specify the AC voltage that you want to generate.

You can specify an output voltage as low as 0.0 V, but the voltage that is actually generated will not be lower than a value in the range of 0.1 V to 0.6 V (the value varies depending on factors such as the output voltage range and the temperature).

• DC mode

Specify the DC voltage that you want to generate.

• AC+DC mode

Specify the AC and DC voltages that you want to generate.

The AC voltage setting is shared between AC and AC+DC modes.

The DC voltage setting is shared between DC and AC+DC modes.

The set AC and DC voltages must meet the following conditions: (1) they must be within the setting range of the voltage limit and (2) the AC+DC waveform’s peak value must be within -431 V to 431 V when the H range is selected and within -215.5 V and 215.5 V when the L range is selected.

When the output is on

If the output is on, the measured value (output terminal voltage) and the setting are displayed. You can adjust the output voltage while viewing the output voltage setting and the measured value.

If you are using the rotary knob to set the value, you may increase or decrease the value too much because the display response is slow. Until you have an intuitive understanding of the display response speed, change the output voltage while viewing the voltage setting or make small changes to the output voltage.

Output voltage setup procedure

WARNING

Risk of electric shock.

Do not touch the OUTPUT terminal block, the outlets, and the sensing terminal block.The time required for the internal capacitors to discharge when no load is connected is approximately 0.1 seconds.

In DC mode, even if the output is off, if a capacitor, battery, or similar item is connected as the load, a voltage remains in the device that is connected to the OUTPUT terminal block, the outlets, and the sensing terminal block until the load’s energy is discharged.

CAUTION

When you turn the output on, several volts of undershoot or overshoot may occur for several tens of microseconds.

Each time that you press OUTPUT, the output toggles between on and off.

• Output on

“OUTPUT ON” is shown on the display.

A voltage and frequency that correspond to the output mode and output range that you have specified are generated.

• Output off

FORCE

The output is on when the power is turned on.

Impedance when the output is off

The internal circuits and the output of the PCR-LE2 Series are not separated by a mechanical switch or relay. The PCR-LE2 Series turns the output off by electrically increasing the output impedance. This enables you to turn the output on and off without chattering. When the output is off, the output is set to high impedance, and the output voltage is nearly 0 V.

Even when the output is on, the following impedances are present, so if the load is a battery or a similar device, a slight current may flow into the PCR-LE2 Series, and the load may be discharged.

Voltage surge suppression when the output is turned off

You can set the voltage surge suppression that is activated when the output is turned off.

When the output is off, the output of this product is at high impedance.

If voltage surge suppression is set to ON (factory default setting), immediately after the output is turned off, the output voltage is set to 0 V (low output impedance), and then the impedance is changed to high. To prevent large overshooting and undershooting by the load immediately after the output is turned off, we recommend that you use the PCR-LE2 Series with the voltage surge suppression set to on.

When voltage surge suppression is on, an unexpected current may flow through the product immediately after the output is turned off depending on the connected load (power conditioner, regenerative inverter, battery, etc.). This may affect the test. Turn voltage surge suppression off for the above loads.

Press CONFIG (SHIFT+OPR MODE), 1/2 (F6), and then SURGE S (F2) to set voltage surge suppression.

Setting the aperture time (measurement time)

With a longer aperture time, the measurements become more stable, but it takes longer to update the display of the measured values. Guidelines for the aperture time when the signal includes an AC component are given below.

• When the period of the AC is known, you can obtain the most accurate measurement results if you set the aperture time to an integer multiple of the period.

Example: If the period of the AC component is 0.1 s, you can obtain the best results in the shortest time if you set the aperture time to 0.1 s.

• When the period of the AC component is unknown, you can obtain comparatively stable measurement results if you set the aperture time to a value that is at least 10 times the expected period.

If the period is set greater than the aperture time, line voltages cannot be measured correctly.

If the harmonic current analysis function is in use and the period is set greater than the aperture time, correct measurements cannot be made.

Press OTHERS (SHIFT+MEMORY), 1/3 (F6), 2/3 (F6), and then APERTUR (F1) to set the aperture time.

Factory default is 0.4 s.

Load level meter

The load level meter displays the ratio of the output current (which is detected as the current flowing through the load) to the rated current on a bar graph. This can be used to determine the approximate output current supply capability. The full scale of the load level meter is 1.1 times the rated current or the current limit, whichever is less.

During single-phase, three-wire output, the load level meter displays the U phase at the top and then the V phase.

During three-wire output, the load level meter displays the U phase at the top followed by the V phase and W phase.

The full scale bar (the right-most bar that lights red) of the load level meter lights on the verge of an overload.

When the PCR-LE is on the verge of an overload, the internal temperature increases. Even if the load is reduced, the full scale bar may continue to light dimly in red. When cooling is complete, the full scale bar turns off.

If overload conditions occur repeatedly while the full scale bar is lit, an alarm (ALM-06: OVERLOAD) may be generated.

Rated current and load level meter display

The output current varies depending on the load. The rated current is automatically derated (reduced) depending on the output conditions (output voltage, frequency, and load power factor).

For details of rated output current, see ”About the output and the load”.

The rated current is automatically derated (reduced) depending on the output conditions (output voltage, frequency, and load power factor).

Examples of calculating the rated currents for single-phase three-wire output and three-phase output for the PCR6000LE2 are given below.

• If the output phase voltage is 80 V, the load power factor is 0.6, and the output frequency is 50 Hz,

the rated current is 20 A × 0.825 = 16.5 A.

• If the output phase voltage is 250 V, the load power factor is 0.4, and the output frequency is 60 Hz,

the rated output current is 2 000 W/250 V × 0.65 = 5.3 A.

• If the output phase voltage is 80 V, the load power factor is 0.6, and the output frequency is 10 Hz,

the rated current is 20 A × 0.775 = 15.5 A (≤ 16.5 A).

Action to perform when the current limit is exceeded

You can set the action to perform (whether the output is turned off) when the current exceeds the current limit. In AC mode, you can set the time that elapses before the output is turned off when the current limit is exceeded.

The current limit function operates on the rms value of the current.

Action: Turn the output off (ENABLE)

• The limit has not been exceeded

• The limit has been exceeded

In AC mode, the output is turned off after the specified trip time has elapsed.

In DC mode and AC+DC mode, the output is turned off 1 second after the limit has been exceeded.

There is a delay in the response depending on the aperture time setting. After the output is turned off, there is a period of approximately 120 seconds (the “Busy” state) during which the output cannot be turned on.

Action: Do not turn the output off (DISABLE)

• The limit has not been exceeded

• The limit has been exceeded

The output voltage is controlled so that the current limit is not exceeded.

Press I and then TRIP (F2) to select the action to perform when the limit is exceeded.

If a current that is greater than the current limit flows, “OVERLOAD” lights, and the output voltage is controlled so that the current does not exceed the current limit.*1

*1. This is calculated as an rms value. The current limit may be exceeded for a few seconds because of the relationship between the measurement processing time and the voltage resolution. The current may oscillate (increase and decrease) while it is being controlled.

If you have selected ENABLE (to turn the output off)

To clear the alarm, press ALM CLR (SHIFT+CLR).

CAUTION

Risk of product malfunction. If an overload occurs, be sure to remove the cause of the problem, and then press OUTPUT.

If you have selected DISABLE (to not turn the output off)

If you have selected to not turn the output off (DISABLE), you will not be able to:

Turn soft start on (set the rise time).

Execute power line abnormality simulations.

Execute sequences.

Use the compensation function’s software sensing and regulation adjustment.

- Note -

If the load short-circuits, if an extreme overload occurs, or if the difference between the output voltage and the output voltage setting during output voltage control is large (the output voltage setting is high), (1) the internal semiconductor protection (OCP) may be activated and the output voltage waveform may be distorted or (2) an alarm (ALM-03: OCP) may occur.

Setting the time (Trip time) that elapses before the output is turned off when the current limit is exceeded

In AC mode, you can set the amount of time that elapses after the current limit is exceeded (the amount of time during which the current limit is continuously exceeded) before the output is turned off. This is useful when you don’t want the output to be turned off due to issues such as inrush current causing short-term overloads.

If the voltage setting is at or lower than 10 V (L range) or 20 V (H range), the output will turn off after 3 s even if you set the trip time to 4 s or longer.

The amount time until the output is turned off may become large due to the state of the load or the timing of the PCR-LE2 Series internal current measurement. There is a delay in the response depending on the aperture time setting.

If the full scale bar of the load level meter continues to be lit, the temperature inside the PCR-LE2 is high. If an overload occurs repeatedly, the time until the output is turned off may be shortened.

Press I, TRIP (F2), and then TRIP TIM (F5) to set the time that elapses before the output is turned off.

Using Protection Functions

“What to do if the breaker trips

The PCR-LE2 Series has the following protection functions.

Input voltage drop protection

Overheat protection (OHP)

Overload protection

Internal semiconductor protection (OCP)

Output undervoltage protection (UVP)

Output overvoltage protection (OVP)

If a protection function is activated, an alarm sounds, “ALARM” is displayed on the screen, and the output is turned off.

During master-slave parallel operation(optional), if an alarm occurs on one unit, the entire system’s output will be turned off.

Clearing alarms

Press ALM CLR (SHIFT+CLR) to clear the alarm, and then fix the problem that caused the alarm.

If an alarm still occurs even after you have corrected all the causes of alarms, the PCR-LE2 Series may be malfunctioning. Stop using it immediately, and contact your Kikusui agent or distributor. Inform the individual that you contact of the alarm code that is displayed.

Input voltage drop protection

If the input voltage drops lower than the rating, the input voltage drop protection function is activated, and an alarm (AC INPUT LOW) is generated. Adjust the input voltage so that it is within the range in the specifications. If the input power supply wiring is long, use wires that have a large diameter to make the voltage drops smaller.

Overheat protection (OHP)

If the internal temperature rises to an abnormal level, the overheat protection is activated, and an alarm (ALM-02: OHP) is generated. Leave the PCR-LE2 Series on, and wait for approximately 10 minutes.

If the alarm has stopped occurring after 10 minutes, the PCR-LE2 Series may have been installed incorrectly, or the dust filter may be clogged.

If there are no problems with the installation or the dust filter, stop using the PCR-LE2 Series immediately, and contact your Kikusui agent or distributor to request repairs.

Overload protection

If the output current exceeds the rated current or the current limit, the overload protection is activated, and an alarm is generated (ALM-06: OVERLOAD).

During reverse power flow, the protection is activated at 30% of the rated current or the current limit, whichever is less.

You can set how the PCR-LE2 Series acts when the current limit is exceeded.

Output undervoltage protection (UVP) and output overvoltage protection (OVP)

UVP and OVP judgment varies depending on the voltage mode.

AC mode: Judgment is based on the rms voltage measurements.

DC mode: Judgment is based on the averaged voltage measurements.

AC+DC mode: Judgment is based on both the rms and averaged voltage measurements.

• Output undervoltage protection (UVP)

If the output voltage drops below the UVP setting and remains there for approximately 1 second, the output undervoltage protection will be activated. An alarm (ALM-07: UVP) will be generated.

• Output overvoltage protection (OVP)

If the output voltage exceeds the OVP setting and remains there for approximately 1 second, the output overvoltage protection will be activated. An alarm (ALM-00: OVP) will be generated.

• Setting UVP and OVP

In AC mode, specify an rms value. In DC mode, specify an average value.

In AC+DC mode, specify an rms value. To set an average value, change to DC mode, set the average value, and then return to AC+DC mode.

For single-phase three-wire output and three-phase output, set the limits using phase voltages.

During single-phase three-wire output and three-phase output (optional), set the limits using phase voltages.

To set the OVP value, press V, PROTECT (F3), and then OVP (F1).

To set the UVP value, press V, PROTECT (F3), and then UVP (F2).

If PROTECT(F3) does not appear, hold down F6 until it appears.

Internal semiconductor protection (OCP)

This protection function protects the internal semiconductors of the PCR-LE2 Series. The internal semiconductor protection function will not be activated if you follow the PCR-LE2 Series usage guidelines outlined in the specifications. If a temporary overcurrent - such as an inrush current - occurs, the internal semiconductor protection function will be activated. If the internal semiconductor protection function remains activated for a set amount of time, an alarm (ALM-03: OCP) will be generated.

If the internal semiconductor protection function is activated, the output voltage waveform will be distorted.

In AC mode, you can set the time that elapses after the internal semiconductor protection function is activated before an alarm is generated. An alarm will only be generated if the internal semiconductor protection function circuit remains activated continually for the specified length of time. This is useful when you don’t want alarms to be generated due to short-term overloads such as those caused by inrush current.

In DC mode and AC+DC mode, an alarm is generated 1 second after the internal semiconductor protection is activated.

“OCP” is displayed when the internal semiconductor protection is activated.

After the alarm is generated, there is a period of approximately 120 seconds (the “Busy” state) during which the output cannot be turned on. The time until the “Busy” indication is cleared is displayed. The time until the “Busy” indication is cleared is displayed.

If the internal semiconductor protection is activated repeatedly, the PCR-LE2 Series may malfunction.

Setting the time that elapses before an alarm is generated

In AC mode, you can set the time that elapses after the internal semiconductor protection has been activated (the amount of time during which the internal semiconductor protection is continually activated) before an alarm is generated.

The amount time that elapses before an alarm is generated may increase depending on the overload state.

Even if an alarm is not generated, the output voltage waveform will be distorted because the internal semiconductor protection circuit has been activated.

Press I, 1/2 (F6), and then OCP TIM (F1) to set the time that elapses before an alarm is generated.

Dealing with alarms

If an alarm has occurred, follow the remedies shown below, wait for at least 1 minute, and then resume the operation.

If you remove the problem that caused the internal semiconductor protection to be activated, the alarm will be cleared automatically. While the internal semiconductor protection is activated, pressing ALM CLR (SHIFT+CLR) will not clear the alarm.

• Linear load

If the current has exceeded the rated current, decrease the load.

If the power factor is low (the phase is lagging), use a phase-advancing capacitor or similar device to increase the power factor.

If the power factor is low (the phase is leading), connect a dummy resistance in parallel to the load to increase the power factor.

• Capacitor-input rectifier load

Decrease the peak current.

• Load that draw an inrush current

Decrease the inrush current.

Using Protection Functions (Cont.)

What to do if the breaker trips

The PCR12000LE2/PCR18000LE2/PCR27000LE2 do not have a breaker.

On the PCR6000LE2 and PCR9000LE2, if an output current of 10 A or greater flows from one of the outlets on the front panel, the breaker next to the outlet may trip, which will cut off the outlet’s output. If the breaker trips, the red button (the breaker button) will pop out.

The total output current that can be generated from the two outlets and the OUTPUT terminal block on the rear panel is the rated output current. If the rated value is exceeded, the overload protection function is activated.

For example, during single-phase output on the PCR6000LE2, when the output voltage is 100 V (the 100 V range), the load power factor is 1, and the output frequency is 50 Hz, if an output current of 10 A is flowing from each outlet, the maximum output current that can be generated from the OUTPUT terminal block is (60 A - 10 A - 10 A =) 40 A.

Turn the POWER switch off.

2

Press the breaker button in.

3

Adjust the load so that the output current is less than or equal to 10 A.

Using the Synchronization Function

The synchronization function synchronizes the frequency and phase of the PCR-LE2 Series output voltage with a 50 Hz or 60 Hz input power supply. This is valid in AC mode and AC+DC mode.

This is useful in situations such as when the display of an external measuring instrument is not stable.

Setting the synchronization delay phase angle enables you to manage the synchronization phase of the input voltage on the three-phase input model with a high degree of precision.

Turning the synchronization function on disables the frequency limit function.

Turning the synchronization function on and off

If the input voltage frequency is outside of the rated range or if the input power supply voltage distortion and the noise are extremely large, synchronization is not possible. In these situations, “SYNC NG” is displayed.

If the frequency when you are using the synchronization function is lower than the lower limit, the frequency is set to the lower limit.

If the frequency when you are using the synchronization function is higher than the upper limit, the frequency is set to the upper limit.

Using the Voltage compensation Function

The compensation function compensates for voltage drops in the load cables when the load is connected to the PCR-LE2 Series over a long distance. The PCR-LE2 Series has three types of compensation functions: soft sensing, hard sensing, and regulation adjustment. Use the different compensation functions depending on how you need to use the PCR-LE2 Series.

Wiring the hard sensing and soft sensing functions

Compensation function setup procedure

Checking the sensing functions (excluding the regulation adjustment function)

During single-phase, three-wire output and three-phase output, regulation adjustment is invalid.

WARNING

Risk of electric shock.

• Before you connect the load or the sensing cables, turn the POWER switch off, and then turn off the switchboard.

• Firmly attach the terminal box cover.

• Hard sensing

Connect the PCR-LE2’s internal output voltage compensation point directly across the load. Because compensation is performed in real time, the output voltage can be stabilized at a high speed.

Because the impedance (the combination of the resistance and the inductance) of the power line across the load will be included in the compensation circuit, the power circuit’s stability decreases. The PCR-LE2 Series operations may become unstable (for example, it may oscillate) depending on the wiring and the load type. Because the power wires of each phase (L and N) are not paired during single-phase three-wire output or three-phase three-wire output, the operation tends to be more unstable than during single-phase output.If the operations become unstable, use soft sensing.

It is recommended that you use soft sensing if you are using a load that does not require a fast output voltage response speed.

You cannot use hard sensing in the following situations.

When the output is on

When you are setting the output impedance (ON)

When you have selected the normal response speed (MEDIUM).

• Soft sensing

The voltage of the sensing point is measured by the PCR-LE2 Series measurement functions, and any insufficiencies in the voltage are automatically compensated for. The performance of the PCR-LE2 Series such as the stability of the voltage, output voltage response to sudden changes in the load current, and waveform quality (distortion ratio) is lower than that available during normal operation.

Even in DC mode, the performance is lower than that available during remote sensing of a normal DC power supply.

The maximum voltage that soft sensing can compensate is “the PCR-LE2 Series’ output voltage ±10 %.” The maximum output voltage during compensation is limited by the rated voltage of the PCR-LE2 Series.

If the frequency is less than 40 Hz, soft sensing is disabled.

You cannot use soft sensing in the following situations.

When the output is on

When in AC+DC mode

When you are setting the output impedance (ON)

When you have configured the PCR-LE2 Series so that it does not turn output off when the current limit is exceeded (DISABLE)

When you have specified the waveform bank

When power line abnormality simulations are being performed

When sequences are being performed

When soft start is on.

• Regulation adjustment

This function calculates the voltage drops that are caused by the output current and increases the output voltage just by the calculated voltage drops.

Use this function when there is a great distance between the PCR-LE2 Series and the load and you want to stabilize the voltage across the load. This function does not require you to connect the sensing cables that the hard sensing and soft sensing functions require.

The performance of the stabilization accuracy, distortion ratio, and response speed of the voltage is lower than the normal performance of the PCR-LE2 Series. Depending on how you are using the PCR-LE2 Series, you may not be able to use this function. Check the operation that you will perform before you use the regulation adjustment function.

The maximum voltage that regulation adjustment can compensate is “the PCR-LE2 Series’ output voltage + 10 %.” The maximum output voltage during compensation is limited by the rated voltage of the PCR-LE2 Series. If the output current is 10 % or less of the maximum rated current, the voltage is not compensated.

You cannot use regulation adjustment in the following situations.

When the output is on

When in AC+DC mode, in DC mode

When you are setting the output impedance (ON)

When you have configured the PCR-LE2 Series so that it does not turn output off when the current limit is exceeded (DISABLE)

When you have specified the waveform bank

When power line abnormality simulations are being performed

When sequences are being performed

When soft start is on.

Wiring the hard sensing and soft sensing functions

We recommend that you run the load wires alongside each other and tie them together at several points with cable ties. Connect between the output terminal and load with the shortest wires possible.

The sensing feature can compensate up to 1.5 V for a single line. Select a load cable that has sufficient current capacity to prevent the voltage drop in the cable from exceeding the compensation voltage.

As the PCR-LE2 Series output voltage becomes small, so too does the detected voltage. If the PCR-LE2 Series output voltage is small, reduce the voltage drops in the cables by using cables that have large diameters to wire the load, connecting the load so that the cables are as short as possible, and taking other similar precautions.

CAUTION

Risk of damage to the product and the load. If the sensing cables become disconnected or the polarities are incorrect, an overvoltage will be generated in the output. The protection function will be activated and the output will be turned off, but an overvoltage will be generated for the several hundreds of milliseconds before the protection function is activated.

On the PCR6000LE2 and PCR9000LE2, pull out the terminal block tray, and then connect the sensing cables.

On the PCR12000LE2, PCR18000LE2, and PCR27000LE2, remove the SENSING terminal cover, and then connect the sensing cables.

Use AWG22 to AWG16 cables when connecting to the sensing terminals. Strip approximately 10 mm of coating from the end of the cables.

The following figure illustrates how to connect sensing cables to the PCR6000LE2 for single-phase output.

1

Check that the POWER switch is turned off.

2

Check that the load’s power switch is off.

If you cannot turn the load off, install a dedicated terminal block for sensing. Do not connect the load to this dedicated terminal block for sensing.

3

Connect the N SENSING terminal to the N terminal on the DUT using sensing cables. In the same way, connect the L SENSING terminal to the L terminal on the DUT.

Connect the wiring so that the product is as close to the load as possible.

Using the Voltage compensation Function (Cont.)

Wiring the hard sensing and soft sensing functions (Cont.)

• Single-phase output

• Single-phase three-wire output

• Three-phase output

Wiring the regulation adjustment function

After you finish connecting the load, turn the output on. Then, set the output voltage to the voltage that is required across the load. Because of voltage drops in the load wiring, the voltage across the load is lower than the voltage generated by the PCR-LE2 Series. Use a voltmeter (or other instrument that enables you to measure voltage) to check whether the voltage across the load is the required voltage.

The maximum voltage that regulation adjustment can compensate is “the PCR-LE2 Series’ output voltage + 10 %.”

Using the Voltage compensation Function (Cont.)

Checking the sensing functions (excluding the regulation adjustment function)

When you are using the hard sensing function or soft sensing function, after you finish wiring the sensing cables, check that there are no wiring errors. Turn the load’s power switch off before you perform this check.

Turn the POWER switch on.

6

Check whether a voltage of several tens of volts is being generated.

An output being generated in this situation indicates that there are connection errors. Check whether the sensing cables are connected and whether the polarities are correct. If the sensing cables are disconnected or the polarities are incorrect, a voltage will be applied across the load (at the sensing point) for approximately one second until the protection function is activated.

If the sensing cables are not firmly connected, an alarm (ALM-07: UVP or ALM-22: SENSING FAILURE) may be generated. If the polarities of the sensing cables are not correct, an alarm (ALM-00: OVP) may be generated. Connect the cables correctly.

If you are installing a dedicated terminal block for sensing, check the sensing function before you connect the load to the terminal block.

Using Power Line Abnormality Simulations

In AC mode, you can simulate power supply line errors by stopping the PCR-LE2 Series output (to simulate power failures) and decreasing and increasing the voltage (to simulate voltage dips and pops).

Using Power Line Abnormality Simulations (Cont.)

Executing and stopping power line abnormality simulations

You can use this to test switching power supplies and other electronic devices.

A sine wave is generated during the power line abnormality simulations. Even if you have set a special waveform, a sine wave will be generated as soon as you execute the power line abnormality simulation.

You can set these values while output is on or off.

Status signals

Status signals are only generated during the periods defined by T2, T3, and T4 (period T3 when T2 and T4 both equal zero).

Signals are generated from the SEQ STAT OUT terminal (a BNC connector) on the rear panel of the PCR-LE2 Series. Use the configuration settings to set the signal polarity. “H” is approximately 5 V. “L” is approximately 0 V.

The BNC connector is isolated from the PCR-LE2 Series’ INPUT and OUTPUT terminal blocks. However, the common line of the TRIG and STAT signals is shared internally, so it is not isolated from the BNC connector. Also, the BNC connector is not isolated from the SLOT internal circuits. There is a slight time difference (approximately 100 ms) between the status signal output and changes to the actual output.

Status signals may be output when you change the settings of the various parameters.

Press CONFIG (SHIFT+OPR MODE) and then SIG.I/O (F3) to set the status output polarity. The status signal polarity setting is shared with the sequence function.

Sequences are groups of executable units called steps. When a sequence is executed (run), its steps are executed in order, starting with the specified starting step. A single execution of a sequence is completed after the sequence’s specified last step has been executed.

You can use the jump function to skip steps and repeatedly execute all the steps in the sequence except for those that have been skipped.

First, set the starting step, and then set the sequence conditions.

If the last step of a sequence does not turn the output off, the output will remain on when the sequence is complete.

Step’s signal change (ramp)

To change the frequency or voltage linearly over the specified time, select “RAMP ON.” To change the value as a step, select “RAMP OFF.”

If you specify “RAMP ON” in step 0, the signal will change linearly from the current voltage or frequency.

• Signal change of voltage

• Signal change of frequency

• Signal change of phase

During three-phase output (optional), you can set the phase ramp (leading or lagging). This is effective for varying the line voltage.

Signal output and Resuming

If the status signal is enabled, a status signal will be output while a step is being executed.

If the trigger signal output is enabled, a signal is output for several tens of microseconds when a step is executed.

You can apply a trigger signal to resume a paused sequence.

Starting phase angle and the ending phase angle

Steps are managed in terms of time.

If you set the starting phase angle, steps will start from the specified phase angle.

Phase wait time is the duration from the point when the step time of the last step has elapsed to the point where the phase angle reaches the starting phase angle. The phase wait time is dependent on frequency.

If you set the ending phase angle, the PCR-LE2 Series will end the step when the specified phase is reached.

Phase wait time is the duration from the point when the step time has elapsed to the point where the phase angle reaches the ending phase angle. The phase wait time is dependent on frequency.

You can output the same waveform regardless of whether you set the starting phase angle or the ending phase angle.

When a waveform is to be output continuously (the phase does not change suddenly) and you set both the starting and ending phase angles, the waveform may be offset by one period. To avoid confusion, we recommend that you set the starting phase angle and not the ending phase angle (FREE).

Display and signal output during the phase wait time

During the phase wait time, the screen shows the next step number. The elapsed time remains at zero until the next step starts.

The status signal is output while the waveform of the step that is enabled is being output.

Sudden phase change

If you set both the starting and ending phase angles and specify phase change, the phase will change suddenly.

If you set sudden phase change to ON, you can switch between two steps according to the set phase angles. For example, if you set the step n-1’s ending phase angle to 90°, the step n’s starting phase angle to 270°, and set sudden phase change to ON, when the step time of step n-1 elapses and 90° is reached, a transition is made to step n (270° phase angle).

Jump function

The steps in a sequence are normally executed in order starting with the starting step. However, you can use the jump feature to skip over steps and repeat sets of steps by repeatedly executing jumps.

Appendix A in the supplied CD-R operation manual contains sequence tutorials that explain sequence creation basics, phase angle settings, sudden phase changes, and multi-phase operation.

*1. In the same step, do not turn on both the trigger wait setting and the sudden phase change setting (PHAS.CHG). If you do, the sequence cannot be executed.

The BNC connector is isolated from the PCR-LE2 Series’ INPUT and OUTPUT terminal blocks. The common line of the TRIG and STAT signals is shared internally, so it is not isolated from the BNC connector.

The remote control function (excluding LAN remote control) also shares this common line. If you are using a desktop PC to control the PCR-LE2 Series remotely, the communication signal line of the PC is grounded, so the BNC connector will also be set to ground potential. If the signal line that is connected to the BNC connector has an electrical potential compared to ground, the connected device or the PCR-LE2 Series may be damaged when a current flows through the signal line.

There is a slight time difference (approximately 100 µs) between the trigger signal output and changes to the actual output.

Trigger signals may also be output when you change the contents of a sequence.

For signal I/O, high level signals are approximately 5 V, and low level signals are approximately 0 V. For signal input, opening the terminal is equivalent to applying a high level signal, and shorting the input is equivalent to applying a low level signal.

During single-phase, three-wire output or three-phase output (optional), apply signals to and output signals from the U-phase unit.

• Status signal output (STAT.OUT)

Status signals are only output during the time when the step’s waveform is being output.

If you set STAT.OUT to “ON,” signals are generated from the SEQ STAT OUT terminal (a BNC connector) on the rear panel of the PCR-LE2 Series.

• Trigger signal output (TRIG.OUT)

Trigger signals are output during the step’s execution time.

If you set TRIG.OUT to “ON,” signals are generated from the SEQ TRIG OUT terminal on the rear panel of the PCR-LE2 Series for several tens of microseconds.

• Waiting trigger (TRIG.IN)

If set to “ON,” the sequence will be paused after the previous step is finished, and the PCR-LE2 Series will wait for a trigger. If a trigger signal (pulse width of at least 10 μs) is received through the SEQ TRIG IN terminal, the paused is released, and the step is executed.

While waiting for the trigger, the screen shows the next step number. The elapsed time remains at zero until the next step starts.

Jump function

The steps in a sequence are normally executed in order starting with the starting step. However, you can use the jump feature to skip over steps and repeat sets of steps by repeatedly executing jumps.

If the step execution time of the jump origin or jump destination step is less than 500 ms, the peaks of the output voltage waveform of the step that will be executed next may be clipped.

The PCR-LE2 Series automatically adjusts the power supply voltage (Vcc) of the linear amplifier. If you set the execution time of the jump origin step to a value less than 500 ms, the PCR-LE2 Series cannot perform this automatic adjustment. If the peaks of the output voltage waveform are clipped, set the execution time of the previous step to 500 ms or greater, or fix the internal Vcc.

If you set TYPE to “NORM,” both JUMP and JUMP CNT will be disabled.

- Memo -

Setup example for making sudden phase changes

Appendix A in the supplied CD-R operation manual contains sequence tutorials that explain sequence creation basics, phase angle settings, sudden phase changes, and multi-phase operation.

First, set the ending phase angle of the step immediately before the sudden phase change to 90 deg. If the sudden phase change is set to off, the sequence moves to the next step when the phase angle reaches 90 deg after the step time of the previous step elapses, as shown below.

Lastly, set the sudden phase change to on. When the phase angle of the previous step reaches 90 deg, the sequence changes to the next step. The next step begins at 270 deg.

You cannot execute the sequence in the following situations.

• When the voltage range is set to the L range and there is a step whose voltage exceeds the output voltage setting range (Switch the range to the H range, or set the output voltage so that it is within the L range).

• When you have configured the PCR-LE2 Series so that it does not turn output off when the current limit is exceeded (DISABLE).

• When the regulation adjustment or soft sensing compensation function is in use.

• When the L range is selected and a step’s ACVolt or DCVolt setting is outside of the L range.

• When the voltage or frequency is set to a value outside the corresponding limits.

A sequence is complete when all steps are complete. The output state when the sequence is complete is the state specified in the last step.

If you want the output to turn off when the sequence is complete, you need to add a last step that turns the output off.

If the U phase is offset in the last step of the sequence (option), the offset (the U PH OFS icon) will remain even when the sequence is complete. Be sure to press 1/2 and then U PHASE on the sequence screen to clear the offset. The icon will disappear when you clear the offset.

Using the Harmonic Current Analysis Function

You can perform harmonic analysis of the output current. A simplified measurement method is used, so this method does not conform to standards such as IEC. For measurements that conform to the standards, use the Harmonic/Flicker Analyzer KHA3000.

If the period is set greater than the aperture time, correct measurements cannot be made.

The harmonic current analysis function is valid in AC mode.

Generating Special Waveforms (Waveform bank)

You can generate peak-clipped sine waveforms. This is valid in AC mode and AC+DC mode.

You can use remote control to configure user-defined waveforms. For details, see the Communication Interface Manual on the included CD-R.

The PCR-LE2 Series creates reference waveforms for output voltage by performing D/A conversion on the data that is stored in its internal memory. One cycle (phase angle of 360°) consists of 10 horizontal bits and 14 vertical bits.

The reference voltage waveform of the PCR-LE2 Series is a sine wave. A sine wave whose positive peak is 8191 and negative peak is -8191 is assigned.

• Waveform bank

The stored waveform data in memory that corresponds to one waveform is referred to as a waveform bank. The PCR-LE2 Series has 64 waveform banks. Each bank is assigned a number from 0 to 63, which is used to select the waveform. Waveform bank 0 contains a sine wave that is used as the PCR-LE2 Series’ reference voltage waveform. This waveform bank cannot be overwritten. In the factory default settings, all waveform banks have the same waveform (sine wave) as the one that is stored in waveform bank 0.

• Crest factor

The crest factor is the ratio of the AC waveform’s peak value to its rms value.

Crest factor = peak value/rms value.

For a sine wave, the crest factor is 1.41. In the voltage waveforms of commercial power lines, the peaks are clipped, so the crest factor is between 1.2 and 1.4.

These settings cannot be made if you are using the synchronization function.

When you turn the power off, the waveform banks from number 24 to number 63 are set to the factory default setting (a sine wave). Save these waveform banks to a USB memory device as necessary before you turn the power off.

During single-phase, three-wire output and three-phase output (optional), the same waveform is assigned to all phases.

Press OTHERS (SHIFT+MEMORY), WAVE (F2), and then EDIT (F5) to select the waveform (sine wave or peak clipped).

Setting the Output Impedance

The PCR-LE2 Series’ output impedance (output resistance) is approximately 0 Ω. Commercial power supplies have an impedance (resistance) of several milliohms to several ohms. You can set the PCR-LE2 Series’ output impedance. This enables you to simulate the same environment as that which is provided by commercial power supplies.

The impedance that is required for IEC standard tests has a prescribed inductance component, but the output impedance of the PCR-LE2 Series consists entirely of resistance. You can use the PCR-LE2Series to perform rough harmonic current analyses. If you require accurate data, use the Line Impedance Network (LIN Series).

Setting Soft Starts (The voltage rise time)

To prevent the output from being turned off (the alarm from being activated) and the voltage from dropping due to the load device’s inrush current that exceeds the rated capacity of the PCR-LE2 Series, you can control the inrush current by having the output voltage rise gradually when the output is turned on.

Fixing the Internal Vcc

To minimize loss in the linear amplifier section, the PCR-LE2 Series automatically adjusts the linear amplifier supply voltage (Vcc) to a level that is suitable for the output voltage. Because the response speed of the preregulator (DC power supply) that generates Vcc is slower than that of the linear amplifier, the Vcc voltage is set internally (only when the output voltage is being raised) several hundreds of milliseconds before the voltage output is changed. There will be a time lag before the output voltage is actually changed even when you frequently change the output voltage externally.

CAUTION

When the internal Vcc is set to FIXED while the PCR-LE2 Series operates in the DC mode, the operating range will change. Operating the PCR-LE2 Series outside the operating range will cause a malfunction.

You can fix the Vcc voltage of the PCR-LE2 Series. This is useful when you want to prioritize the output voltage response over the product’s efficiency.

Fix the PCR-LE2 Series’ Vcc voltage according to the peak voltage in the output voltage change tests.

When you fix the Vcc, the internal (power) loss increases, so the protection functions may be activated depending on the output voltage (the duration that the voltage is generated for), load conditions, and ambient temperature. Be sure to carry out tests (simulations) in advance, and check how the PCR-LE2 Series operates.

If the Vcc is fixed and the maximum used output voltage is set lower than the peak output voltage, the maximum used output voltage setting is changed to follow the peak output voltage to prevent a malfunction.

Press OTHERS (SHIFT+MEMORY), 1/3 (F6), and then VCC (F1) to set the internal Vcc.

Selecting the Response

The PCR-LE2 Series uses a high-speed amplifier. Depending on the load circuits (especially in the case of capacitive loads) and the wiring conditions, the output may become unstable may oscillate.

You can set the response speed of the internal amplifier (to one of the following two levels) according to the load conditions and how you will use the PCR-LE2 Series.

• Normal speed response (MEDIUM)

This is used in power-supply-environment testing - including tests such as low-frequency immunity tests - to cover a range of frequencies from commercial power line frequencies to the frequencies used by ship and aircraft power supplies.

• High stable response (SLOW)

This is used to provide stable power to a variety of loads. For example, this setting would be used on the power supplies at an EMC test sight. Even if a capacitor that has a large capacity (such as a large noise filter) is connected to the output of the PCR-LE2 Series, this setting can be used to provide stable operations. This setting provides a sufficient response speed to generate commercial power line frequencies, so it can also be used in typical evaluation tests.

Press OTHERS (SHIFT+MEMORY), 1/3 (F6), and then RESP (F3) to set the response.

Using the Power Management Functions

The PCR-LE2 Series has the following two power management functions: a sleep function and a power-saving function

Sleep function

Power-saving function

Sleep function

You can set the PCR-LE2 Series so that it enters sleep mode after a certain amount of time passes with its power on but no output being generated (the output is off).

When sleep mode is enabled and the specified time elapses, the internal power units turn off, which reduces power consumption.

“zzz...zzz...Please push ESC key” is displayed faintly on the screen (it scrolls across the screen).

Press ESC to exit sleep mode. You cannot turn the output on for the few seconds between when sleep mode is exited and the internal power units turn on (the “Busy” state).

Press SLEEP (SHIFT+1) to set the sleep function.

The PCR-LE2 Series enters sleep mode instantly.

Power-saving function

The PCR-LE2 Series is made of units. Each model contains power units that correspond to the rated output capacity.

If you are using the PCR-LE2 Series at less than the rated output capacity, the PCR-LE2 Series can operate using only the necessary power units. Even if you are not supplying power to a load, the power units suffer power loss. Operating the PCR-LE2 Series with the minimum number of power units reduces power consumption.

Set the maximum power that you will use. If the specified power capacity is exceeded, the protection functions will be activated.

Press OPR MODE and the POW SAV (F4).

Controlling the Output Using External Analog Signals

The output can be controlled using external analog signals by installing the analog signal interface board (EX05-PCR-LE/ EX06-PCR-LE) to the slot3.

For details of installing the board on the PCR-LE, see the setup guide of EX05-PCR-LE/EX06-PCR-LE.

• Amplifying the input waveform (EX05-PCR-LE only)

- Note -

Only single-phase output is valid on the PCR6000LE2 and PCR9000LE2.

• Varying the voltage of the output AC waveform using DC signals (EX06-PCR-LE only)

• SIGNAL I/O Connector

• Controlling the PCR-LE2 through external contacts

You can turn the output on and off, execute and stop sequences, clear alarms, and shut down the output.

• Monitoring the operation status

You can monitor the output status, alarm status, busy status, current peak limit status, and overload status.

CAUTION

You cannot set the voltage limit when the PCR-LE2 is being controlled using external analog signals. Accidentally applying an excessive external voltage may damage the load.

Setting the aperture time (only when using EXT)

To use an external signal source (EXT), set the aperture time.

If the aperture time is not set, the voltage and current that are being output may be different from what are displayed on the panel.

The aperture time setting was added in firmware version 5.00. As a result, the function for setting the estimated minimum frequency that was available in firmware version 4.99 and earlier is no longer available.

Setting the internal Vcc

If you set the signal source to EXT or EXT+INT, the internal Vcc is changed to a fixed value. Set the Internal Vcc value to the voltage that you want to output (peak value) + 10 V.

If the internal Vcc is set to a value greater than the actual output voltage, the protection function may be activated. If the internal Vcc is set to a value less than the actual output voltage, a few hundred milliseconds of response delay will occur.

Outputting the signal

After you set the signal source, polarity, and the estimated minimum frequency (EXT only), apply an external signal to the INPUT terminal.

Controlling the PCR-LE2 through external contacts

Wiring

To minimize the influence of noise on the output, use a two-core shielded wire or a twisted-pair wire to connect the control terminals and the external contact. Make the wires as short as possible. Susceptibility to the effects of noise increases as the wires get longer. When wires are long, proper operation may be hindered even if a cable with anti-noise measures is used.

The release voltage across pins is approx. 12 V maximum, and the short circuit current is approx. 8.5 mA maximum. (The internal circuit is pulled up to 12 V through 1.3 kΩ.)

Use parts with a contact rating of 12 Vdc and 8.5 mA for the external contact.

High level input voltage (HIGH): 11 V to 12 V, or open circuit

Low level input voltage (LOW): 0 V to 1 V

When using a shielded cable, connect the shield to the chassis.

For long-distance wiring

When wiring over a great distance, use a small relay and extend the coil side of the relay.

Rated output current characteristics (Derating)

The output voltage ratio is a percentage where 100 % represents an output voltage of 100 V (output L range) or 200 V (output H range) in AC mode or DC mode. The output current ratio is a percentage where 100 % represents the maximum rated output current in AC mode or DC mode.

The instantaneous peak current ratio is the instantaneous peak current expressed as a percentage of the rated maximum output current.

The rated output current in AC mode depends on the output conditions (output voltage, load power factor, output frequency). The rated output current under given output conditions is the value obtained by converting the smaller of the two values: the product of the output current ratios derived from fig. 1 (output voltage) and fig. 3 (load power factor) and the output current ratio derived from fig. 4 (output frequency).

Maximum peak current (AC mode)

This is the maximum continuous output current (peak value in Apeak) that the PCR-LE Series can supply when using a capacitor-input rectifier load.

Maximum peak current = rated maximum output current (rms) × 4

Output voltage: 100 V to 150 V (for output L range)

200 V to 300 V (for output H range)

Output frequency: 40 Hz to 999.9 Hz

Maximum instantaneous current (DC mode/ AC+DC mode)

This is the maximum instantaneous output current (peak current in Apeak) that can be supplied to the load in DC mode or AC+DC mode.

Maximum instantaneous current = Rated maximum output current × 3.6

Instantaneous peak currenst (AC mode)

This is the maximum instantaneous output current (peak current in Apeak) that can be supplied to the load in AC mode.

This depends on the output range, voltage setting, and instantaneous output voltage.

The instantaneous peak current near the peak value of the instantaneous output voltage is four times the rated maximum output current (maximum peak current), but it decreases in accordance with the reduction in the absolute value of the instantaneous output voltage.

Figs. 10 and 11 show “Instantaneous output voltage versus instantaneous peak current ratio” for the representative voltage settings of each range.

Instantaneous peak current ratio

This is the instantaneous peak current as a percentage where the rated maximum output current is 100 %.

Output voltage ratio

This is the output voltage as a percentage where 100 V for the output L range or 200 V for the output H range is 100 %.

Output voltage waveform distortion ratio

This is the total harmonic distortion (in %) of the output voltage waveform when the output voltage is between 80 V and 150 V (for output L range) or between 160 V and 300 V (for output H range) and the load power factor is 1.

Output voltage response speed

This is the time duration defined by the output voltage change exceeding 10 % of the total change and then returning back to 10 % or less of the total change when the output current ratio has changed from 0 % to 100 % under the following conditions: the output voltage is 100 V (for output L range) or 200 V (for output H range) and the load power factor is 1 (in AC mode). (The unit is µs.)

Capacitor-input rectifier load (circuit)

This is a load whose rectifier circuit part is constructed as shown below. The rectifier circuit is used to convert the input AC voltage into the DC voltage that the device needs to operate.

The peak input current is normally approximately two to four times the rms value. The conduction angle (the period that the current is flowing for) centered on the peak output voltage (phase angle of 90 deg or 270 deg) is approximately 20 deg to 90 deg.

Derating

"Derating" means "reducing." In general, this refers to using a device at reduced maximum rated values (such as the voltage and the current) depending on the ambient conditions (such as the temperature and load).

Voltage dip

This refers to situations in which the voltage in a commercial power line drops momentarily due to the effects of lightning and other similar phenomena.

Generally, these voltage drops last for several tens of milliseconds to several hundreds of milliseconds, and the voltage drops by 20 % to 80 %.

• Fig.10 Instantaneous output voltage ratio versus instantaneous peak current ratio (AC mode L range, excluding three-phase three-wire output)

The instantaneous output voltage is the instantaneous value of the output voltage waveform.

This shows the instantaneous peak current ratio in relation to the instantaneous output voltage when the output voltage is set to 50 V, 100 V, and 150 V.

For example, the instantaneous peak current that can be supplied when the setting voltage is 100 V is 160 % of the rated current (rms) when the instantaneous output voltage is 50 V and 280 % of the rated current (rms) when the instantaneous output voltage is 100 V.

During three-phase three-wire output, the instantaneous peak current ratio is limited also by the instantaneous output voltage of other phases.

• Fig.11 Instantaneous output voltage ratio versus instantaneous peak current ratio (AC mode H range, excluding three-phase three-wire output)

The instantaneous output voltage is the instantaneous value of the output voltage waveform.

This shows the instantaneous peak current ratio in relation to the instantaneous output voltage when the output voltage is set to 100 V, 200 V, and 300 V.

For example, the instantaneous peak current that can be supplied when the setting voltage is 200 V is 160 % of the rated current (rms) when the instantaneous output voltage is 100 V and 280 % of the rated current (rms) when the instantaneous output voltage is 200 V.

During three-phase three-wire output, the instantaneous peak current ratio is limited also by the instantaneous output voltage of other phases.

About the output and the load (Cont.)

Rated output current in AC mod (Cont.)

How the rated output current is determined on the PCR6000LE2

Example 1: The output voltage is 80 V (L range), the load power factor is 0.6, and the output frequency is 50 Hz.

Example 2: The output voltage is 250 V (H range), the load power factor is 0.4, and the output frequency is 60 Hz.

Example 3: The output voltage is 80 V (L range), the load power factor is 0.6, and the output frequency is 10 Hz.

The rated output current in AC mode depends on the output conditions (output voltage, load power factor, output frequency). The rated output current under given output conditions is the value obtained by converting the smaller of the two values: the product of the output current ratios derived from fig. 7 (output voltage) and fig. 8 (load power factor) and the output current ratio derived from fig. 9 (output frequency).

The full scale of the load level meter of control panel is set to 1.1 times the calculated rated current or the current limit, whichever is less.

Example

If you use the PCR-LE2 Series under conditions that exceed those that produce the rated output currents described below, the protection functions may be activated, which may cause the output voltage to drop, or turn off the output.

Example 1: The output voltage is 80 V (L range), the load power factor is 0.6, and the output frequency is 50 Hz.

From the fig.7, the output current ratio at an output voltage of 80 V is 100 %. - - -(a)

From the fig.8, the output current ratio at a load power factor of 0.6 is 82.5 %. - - - (b)

From the fig.9, the output current ratio at an output frequency of 50 Hz is 100 %. - - - (c)

From (a) and (b), the output current ratio at an output voltage of 80 V and a load power factor of 0.6 is

(a)×(b) = 82.5 % - - - - - - - - - - - - - - - - - - - - - - - - (d)

Because (d) is smaller than (c), the output current ratio is limited by (d), which was calculated as (d). Therefore, the maximum output current ratio is 82.5 %.

On the PCR6000LE2, the rated maximum output current for the output L range is 60 A (Single-phase output), so the rated output current under the above conditions is

60×0.825 = 49.5 A

Example 2: The output voltage is 250 V (H range), the load power factor is 0.4, and the output frequency is 60 Hz.

From the fig.7, the output current ratio at an output voltage of 250 V is 80 %. - - (a)

From the fig.8, the output current ratio at a load power factor of 0.4 is 65 %. - - - (b)

From the fig.9 the output current ratio at an output frequency of 60 Hz is 100 %. - - - (c)

From (a) and (b), the output current ratio at an output voltage of 250 V and a load power factor of 0.4 is

(a)×(b) = 52 % - - - - - - - - - - - - - - - - - - - - - - (d)

Because (d) is smaller than (c), the output current ratio is limited by (d). Therefore, the maximum output current ratio is 78 %.

On the PCR6000LE2, the rated maximum output current for the output H range is 30 A (Single-phase output), so the rated output current under the above conditions is

30×0.52 = 15.6 A

Example 3: The output voltage is 80 V (L range), the load power factor is 0.6, and the output frequency is 10 Hz.

From the fig.7, the output current ratio at an output voltage of 80 V is 100 %. - - (a)

From the fig.8, the output current ratio at a load power factor of 0.6 is 82.5 %. - - - (b)

From the fig.9 the output current ratio at an output frequency of 10 Hz is 77.5 %. - - - (c)

From (a) and (b), the output current ratio at an output voltage of 80 V and a load power factor of 0.6 is

(a)×(b) = 82.5 % - - - - - - - - - - - - - - - - - - - - - - (d)

Because (c) is smaller than (d), the output current ratio is limited by (c). Therefore, the maximum output current ratio is (c) = 77.5 %.

On the PCR6000LE2, the rated maximum output current for the output H range is 30 A (Single-phase output), so the rated output current under the above conditions is

30×0.775 = 46.5 A

About the output and the load (Cont.)

Rated output current in AC mod (Cont.)

How peak current that can be supplied is determined (for single-phase output)

As shown in figs. 10 and 11, “Instantaneous output voltage versus instantaneous peak current ratio,” the peak current supply performance depends on the output range, voltage setting, and instantaneous output voltage.

Figs. 12 and 13 show the range in which peak current can be supplied (range between two solid lines) for the voltage waveforms (broken lines) at the representative voltage settings of each range.

The instantaneous peak current near the peak value of the instantaneous output voltage is four times the rated maximum output current (maximum peak current), but it decreases in accordance with the reduction in the absolute value of the instantaneous output voltage. If this range is exceeded, the protection functions of this product may be activated, which may distort the output voltage waveform or turn off the output.

For loads through which inrush current flows, such as transformers, motors, lamps, and capacitor-input rectifier circuits, check the current waveform, and provide adequate margin so that the peak current supply range is not exceeded. In addition, keep the rms value of the output current from exceeding the rated output current or in the case of reverse power flow, 30 % of the rated output current.

• Fig.12 Voltage waveform versus peak current supply range (AC mode L range)

• Fig.13 Voltage waveform versus peak current supply range (AC mode H range)

How peak current that can be supplied is determined (for three-phase output)

Also for three-phase output, the peak current supply performance depends on the output range, voltage setting, and instantaneous output voltage as shown in fig. 10 and fig. 11, “Instantaneous output voltage versus instantaneous peak current ratio.”

If you are using three-phase four-wire output, read “setting voltage” as “setting phase voltage” and “instantaneous output voltage” as “instantaneous value of phase voltage” in fig. 10 and fig. 11.

If you are using three-phase three-wire output, because the phase voltages of the two phases are connected in series as shown in the following figure, the instantaneous peak current ratio is limited also by the instantaneous output voltage of the other phase. As such, the instantaneous peak current ratio when the instantaneous output voltage of the other phase is near 0 V may be lower than the rating.

About the output and the load (Cont.)

Rated output current in AC mod (Cont.)

Capacitor-input rectifier loads

For electronic devices that have capacitor-input rectifier circuits in their input, when the output voltage approaches the peak output voltage, a peak current several times greater than the output current rms value flows as the output current.

As shown in figs. 10 to 13, keep the maximum peak current near the peak value of the instantaneous output voltage from exceeding four times the rated maximum output current.

*: Output L range is 100 V, and output H range 200 V.

The output current rms should not exceed the rated output current value calculated with the load power factor set to 1, as explained in "Linear load".

If you use the PCR-LE2 Series with an output current that exceeds the rated output current (peak or rms value) specified above, the protection functions may be activated, which may distort the output voltage waveform or turn off the output.

You can only supply the maximum peak current described above without any distortions when the output voltage (the setting) is fixed. If the output voltage setting is changed suddenly (increased), the voltage and current waveforms may be distorted. Even if you are executing power line abnormality simulations or sequences, distortions may occur in the same manner if the output voltage is changed suddenly. To supply the maximum peak current without distortions, fix the output voltage setting and then turn the output on.

Loads that generate surges

Some loads (for example, fluorescent lights) generate surges when the voltage is applied to the load or when the voltage is changed suddenly. When a surge occurs, the PCR-LE2 Series may malfunction. For this type of load, connect a noise filter to the output cable.

Special loads

If you connect a capacitor directly to the OUTPUT terminal block or the OUTPUT outlets, the output waveform may be distorted. In this situation, connect the capacitor to the load side of the output wiring.

Loads that draw an inrush current

For loads such as those listed below, when the voltage is applied to the load or when the voltage changes suddenly, an inrush current (several times to several tens of times the normal current) flows for several cycles to several tens of cycles of the output frequency.

• Transformer and slide transformer (SLIDAC) loads

When a voltage is applied to a transformer or a slide transformer, an inrush current of up to several hundreds of times the normal current will flow for several cycles depending on the timing that the voltage is applied or the residual magnetization in the transformer.

• Motor and lamp loads

When a voltage is applied to a motor or a lamp, an inrush current of several times to several tens of times the normal current flows for several tens of cycles to several hundreds of cycles.

• Capacitor-input rectifier loads

For electronic devices that have capacitor-input rectifier circuits in their input, if the device does not have an inrush current protection (limitation) circuit, an inrush current of several tens to several hundreds of times the normal current flows for several cycles.

As shown in figs. 10 to 13, for capacitor-input rectifier loads, this product can supply maximum peak current up to four times the rated maximum output current near the peak value of the instantaneous output voltage.

For other loads, this product can supply maximum peak current up to 200 % of the instantaneous peak current ratio for the specified trip time (TRIP TIM) even if the rms value of the output current exceeds the rated output current (varies depending on the current waveform, output voltage, output frequency, and the like).

Examples of the instantaneous peak currents that can be supplied when TRIP is set to ENABLE, the output voltage is set to 100 V, and the output frequency is set to 50 Hz are shown in the following table.

*1. The output current ratio as a percentage where 100 % represents the maximum output current of the PCR-LE2 Series

If an inrush current that exceeds the peak currents listed above flows, the protection circuits of the PCR-LE2 Series will be activated, which may distort the output voltage waveform or turn off the output.

Particularly for inductive loads such as transformers and motors, if the protection circuit is activated and the output is turned off, a reverse voltage exceeding the voltage setting may be generated and appear at the output terminals.

• Output voltage ratio versus rated output current in DC mode

Unlike with resistive loads, when a power supply that alternates voltage polarity based on time is applied to an inductive or capacitive load, the current phase becomes lagging or leading to the voltage phase.

If this occurs, there are four possible combinations of the voltage and current polarities. This operation is shown on a graph of voltage (vertical axis) versus current (horizontal axis). The PCR-LE2 Series operates in all four quadrants (and thus the name four-quadrant operation). Power supplies that can operate in this manner are called bipolar power supplies.

Output current ratio [%] of the first quadrant and third quadrant

Output current ratio [%] when the output voltage setting (DCvolt) is between 0 V and 100 V (L range) or between 0 V and 200 V (H range): 100

Output current ratio [%] when the output voltage setting (DCvolt) is 100 V or higher (L range) or 200 V or higher (H range): 100/ Output voltage ratio ×100

Output current ratio [%] of the second quadrant and fourth quadrant

Output current ratio [%] when the output voltage setting (DCvolt) is between 0 V and 100 V (L range) or between 0 V and 200 V (H range): 21

Output current ratio [%] when the output voltage setting (DCvolt) is 100 V or higher (L range) or 200 V or higher (H range): 100/ Output voltage ratio ×21

If you use the PCR-LE2 Series with a current that exceeds the rated DC output current, the protection functions will be activated, which may cause the output voltage to drop or turn off the output.

Peak hold current measurement

The differences between the peak measurement and the peak hold measurement are shown below.

Peak measurement

The peak measurement is cleared once per measurement cycle.

The PCR-LE2 Series makes peak measurements by measuring the current peaks and then taking the maximum absolute value of the measured data. The peak current display shows an absolute value with no positive or negative sign. The peak value can be measured in AC, DC, and AC+DC modes.

Peak hold measurement

The peak hold measurement is held until the maximum peak value is cleared. The peak hold current measurement is useful when you are measuring the inrush current when the power is turned on and in similar situations.

The PCR-LE2 Series makes peak hold measurements by measuring the current peaks and then taking the maximum absolute value of the measured data. The peak current display shows an absolute value with no positive or negative sign. The peak hold value can be measured in AC, DC, and AC+DC modes.

You can capture peaks that continue for at least a specified length of time (t).

The peak current depends greatly on the PCR-LE’s current supply capabilities. Ensure that the output capacity of the PCR-LE Series is sufficient for the load.

Sequence creation basics

This page explains how to use a sequence to output the following waveform.

In this example, use default values for items that are not specified.

Setting Procedure

In the supplied CD-R contains a table for recording sequence operation settings (xls, xlsx, and PDF). You can prevent input errors by entering the settings in this table first and then creating the sequence.

Use the rotary knob or the numeric keypad enter values for items that you want to set. When using the numeric keypad, press ENT after you enter values.

Press SEQ (SHIFT+SIM) to display the sequence screen. Press EDIT (F5) to display the step editing screen.

You can edit the step that has a border around its item or value. 000 is selected. If 000 is not selected, use the rotary knob to select it. You can also select steps by pressing STEP (F1) and then using the rotary knob.

Set the AC voltage. Press AC VOLT (F3).

A border is displayed around the ACV item of step 000. Use the rotary knob to specify 5.0 V.

Press ▼ to move the border to the voltage of step 001. Then, use the rotary knob to specify 10.0 V.

The default AC voltage is 0.0 V. The voltage of step 002 is 0.0 V (if it is not, set it to 0.0 V), so press ▼ twice to move the border to the voltage of step 003. In step 3, the voltage changes from 0.0 V to 10.0 V over 100 ms. This is because the voltage ramp setting is on. Use the rotary knob to set the voltage to 10.0 V, and then press RAMP ON (F5). The voltage ramp indication changes to .

In step 4, the voltage changes from 10.0 V to 0.0 V over 100 ms. Set the voltage of step 4 to 0 V, and set the ramp setting to on.

Set the voltages of steps 6 to 8 and steps 10 and 11 to 5.0 V. This completes the voltage settings.

Press ESC to return to the previous screen. Press FREQ (F2) to set the frequency.

The default frequency is 50.0 Hz. Press ▲ repeatedly until you reach the frequency of 006. (If steps 1 to 5 are not set to 50.0 Hz, start by setting the frequencies from step 1.) Then, use the rotary knob to specify 40.0 Hz.

Press ▼ to move the border to the frequency of step 007. Then, use the rotary knob to specify 80.0 Hz. Likewise, set steps 8 and 9 to 40 Hz. Then, press ▼ to move the border to the frequency of step 010.

In step 010, the frequency changes from 40 Hz to 80 Hz over 100 ms. This is because the frequency ramp setting is on. Use the rotary knob to set the frequency to 40 Hz, and then press RAMP ON (F5). The frequency ramp indication changes to .

In step 11, the frequency changes from 80 Hz to 40 Hz over 100 ms. Set the frequency of step 11 to 40 Hz, and set the ramp setting to on. This completes the frequency settings.

Press ESC to return to the previous screen. Press 1/5(F6) to move to the next step editing screen.

Press TIME (F2) to set the step execution time. Press ▲ repeatedly until you reach the time setting of step 000. Press 100US (F6), use the numeric keys to enter 100 (0:00:00.1000), and press ENT. The microsecond resolution is 100 µs.

The minimum time resolution for the step execution time is 100 µs. Do not set the step execution time to 0 s.

For steps 1 to 11, set the step execution time to 100 ms.

Press ESC to return to the previous screen. The default output setting is on, so there is no need to change it. If it is not on, press OUTPUT (F5). The default settings will be used for the rest of the items. This completes the step settings. If steps 0 to 11 are not set to their default values, set them to default values.

Next, set the sequence conditions.

Press ESC repeatedly until the sequence screen appears. Press COND (F4) to set the starting step number and the ending step number.

The default starting step number is 0. If START STEP is not 000, use the rotary knob to set it to 000.

Press ▼ to move the border to END STEP. The ending step is 011, so use the rotary knob to specify 011.

This completes the sequence settings. Let's run the sequence.

Press ESC to display the sequence screen.

Press RUN (F1) to execute the sequence. You cannot execute the sequence in the following conditions.

If the voltage range is set to the L range and there is a step whose voltage exceeds the output voltage setting range (switch the range to the H range, or set the output voltage so that it is within the L range).

If you have configured the PCR-LE Series so that it does not turn output off when the current limit is exceeded (DISABLE)

If the regulation adjustment or soft sensing compensation function is in use.

If the L range is selected and a step's ACVolt or DCVolt setting is outside of the L range.

If the voltage or frequency is set to a value outside the corresponding limits.

The minimum unit for displaying step execution times is seconds. Steps whose execution time is less than 1 second are displayed as "0:00:00."

A sequence is complete when all steps are complete. The condition that the PCR-LE Series is in when a sequence is completed is the condition specified in the last step of the sequence.

If you want the output to turn off when the sequence is complete, you need to add a last step that turns the output off.

When you have finished setting the sequence, we recommend that you save the settings to a USB memory device.

Connect a USB memory device to the USB port on the front panel. Press OTHERS (SHIFT+MEMORY), 1/2(F6), FILE(F5), SAVE(F3), and SEQ. The name of the file that the sequence will be saved to is displayed in the entry area.

Press SAVE (F4) to save the settings. Do not remove the USB memory device until "File was saved" disappears.

Remove the USB memory device from the USB port.

In a step whose ramp is set to on, the voltage changes linearly from the voltage setting of the previous step to the specified voltage.

Because we want to change the voltage from 0 V to 10 V, the step before the step that will be set to 10 V must be set to 0 V. For this purpose, we will set short starting voltage steps before steps that will be set to 10 V. In this example, steps 2, 4, and 6 are the starting voltage steps. The minimum time resolution for the step execution time is 100 µs. Do not set the step execution time to 0 s.

If you create a sequence without starting voltage steps, the waveform shown below will be output. Note that even if the ramp is turned on in steps 2, because the previous step is set to 10 V, a ramp waveform will not be produced.

Switching steps at specific phase angles

This page explains how to switch steps at specific phase angles to produce a continuous waveform.

Steps are managed in terms of time. If the starting phase angle and ending phase angle are set to FREE (default setting), the next step will start when the step time elapses. The phase is continuous.

The phase angle of step 1 when its step time elapses is 90°. Because the starting phase angle of step 2 is 0°, the PCR-LE waits until the phase angle of step 1 becomes 0° before executing step 2. This duration is the phase wait time. When the phase angle of step 1 reaches 0°, step 2 begins. The PCR-LE does not sweep during the phase wait time.

If you set starting phase angles, the total sequence time will be longer than the specified time by the amount of phase wait time. The phase wait time depends on the specified frequency.

During the phase wait time, the panel shows the next step number.

The status signal is output while the waveform of the step whose STAT.OUT is set to ON is being output.

The trigger signal is produced when the step actually begins.

You can also set the starting phase angle to FREE and the ending phase angle to a specific angle to product the same effect, but to avoid confusion, we recommend that you set the starting phase angle to a specific angle and the ending angle to FREE.

To output a waveform with continuous phase, be sure to set either the starting or ending phase angle to FREE. If you set both the starting and ending phase angles, the waveform may be offset by one period.

In this example, the starting phase angle of step 1 is FREE, so there is no phase wait time. Theoretically, there should not be any phase wait time if the starting phase angle is set to 0°, but depending on the conditions, the waveform may be offset by on period. If the time and phase angle are matched, we recommend that you use FREE. However, if you want to output an waveform accurately according to calculations, you need to shorten the previous step a little (1 ms in this example).

Suddenly changing the phase

To suddenly change the phase, specify a sudden phase change after setting the starting and ending phase angles.

We will explain using an example whose phase changes suddenly from 90° to 270° between steps 2 and 3.

Because step 2 is set to 100 ms and 25 Hz, the phase angle will end at 180° if the ending phase angle is not specified (FREE). Because we want the phase to suddenly change from 90° to 270° between steps 2 and 3, we set the ending phase angle of step 2 to 90°. Step 3 will not begin until the phase angle changes from 180° to 90°, so there will be a phase wait time.

We want the phase to suddenly change to 270° in step 3, so we set the starting phase angle of step 3 to 270° and set the sudden phase change function to on. Step 2 will end at 90°, and step 3 will begin immediately from 270°.

To use sudden phase change, be sure to set the ending phase angle of the previous step and the starting phase angle of the step in which you want the phase to suddenly change. If either phase angle is set to FREE and sudden phase change is set to on, the waveform will not change at the correct phase angles.

Single-phase, three-wire output and three-phase output basics

Single-phase, three-wire output

The figure below shows the output of a user-defined waveform whose U-V phase difference is 180° (factory default setting).

The phase setting is 180°, but the V phase is not 180° out of phase with the U phase. The V phase is an inverted waveform of the U phase.

Three-phase output

The figure below shows the output of a three-step sequence where the U-V phase difference is 120° and the U-W phase difference is 240° (factory default setting).

The V phase is 120° behind the U phase. The W phase is 240° behind the U phase. You can set the U-V phase difference and the U-W phase difference in the sequence step settings.

Phase setting for multi-phase output

This page explains how to set phase angles for multi-phase output. For details on the operation of starting and ending phase angles, see “Switching steps at specific phase angles”. For details on the operation of sudden phase changes, see”Suddenly changing the phase”.

- Note -

For the U phase sudden-phase-change settings, specify the starting phase angle, ending phase angle, and sudden phase change.

For the V phase sudden-phase-change settings, set the U-V phase difference.

For the W phase sudden-phase-change settings, set the U-W phase difference.

In the example below, the U phase suddenly changes from 0° to 180° when step 1 begins.

Because the U-V and U-W phase differences in step 1 are set to OFF, the U-V phase difference remains at 120° and the U-W phase difference remains at 240°. When the U phase is 0°, the V phase is 240°, because it is behind by 120°. The W phase is 120°, because it is behind by 240°. The V phase suddenly changes from 240° to 60° when step 1 begins. The W phase suddenly changes from 120°to 300°.

Next, we will explain how to set the steps so that only the U phase suddenly changes.

In the example below, the U phase suddenly changes from 0° to 30° when step 1 begins. The waveforms of the V and W phases are continuous.

When step 1 begins, the U phase changes from 0° to 30°. If the U-V and U-W phase differences are set to OFF, the V phase will suddenly change from 240° to 270°, and the W phase will suddenly change from 120° to 150°. Because we want only the U phase to change suddenly, we add 30° to the phase differences (150° for the V phase and 270° for the W phase) so that the V and W phases will be continuous. When these settings are made, the waveforms of the V and W phases will be continuous.

You can also set the U phase offset to cause the U phase to suddenly change, but in this case, the U-V/U-W phase difference settings will be offset from the actual phase difference. To avoid confusion, we recommend that you turn off the U phase offset.

For details, see the next section, “Phase sweep”

Lastly, we will explain how to set the steps so that the V and W phases suddenly change. To suddenly change the V phase, set the U-V phase difference. To suddenly change the W phase, set the U-W phase difference.

In the example below, the U-V phase difference is suddenly changed from 120° to 90° when step 1 begins. The waveforms of the U and W phases are continuous.

Step 0 ends when the U phase is 180°. When the U phase is 180° in step 0, the V-phase is 60°, because the U-V phase difference is 120°. Because the U-V phase difference is changed to 90° in step 1, the V-phase starts at 180°-90° = 90°. This means that only the V phase suddenly changes from 60° to 90° when step 1 begins.

The example below shows a sudden phase change in which step 1 begins at 0° when step 0 ends with the V phase at 90°. The waveforms of the U and W phases are continuous.

Because the U-V phase difference is 120°, the V phase is 90° when the U phase is 210°. We want to the V phase to change at 90°, so we set the starting phase angle of step 1 to 210°. The U phase angle is 210° when step 1 begins. To make the V phase suddenly change to 0°, we set the U-V phase angle to 210°. The W phase is continuous, so we leave the U-W phase difference at OFF.

When the U phase angle of step 0 reaches 210°, step 1 begins. The V phase suddenly changes from 90°to 0°.

Phase sweep

First, we will explain the phase sweeping of the U phase.

To sweep the U phase, you have to set the U phase offset.

When a U phase offset is specified, the U-V phase difference, U-W phase difference, starting phase angle, and ending phase angle settings are relative to the U phase reference phase.

Setting a U phase offset causes the U-V/U-W phase difference settings to be offset from the actual phase difference.

In the following example, U phase is swept from 0° to 330° (leading) from step 1 to step 2. V and W phases will not be changed.

Specify the phase to sweep the U phase with the U phase offset.

Because we want to advance the phase from 0° to 330° in step 1, we set the U phase offset of step 1 to 330°.

Phase sweep ramp can be set to leading (LEAD) or lagging (LAG).

Set the ramp of step 1 to LEAD. “- ” is displayed for U PHASE OFFSET.

The U-V phase difference and U-W phase difference are the phase difference from the U phase reference phase.

Because we are not changing the V phase and W phase, we leave their settings at off (U-V phase difference: 120°, U-W phase difference: 240°).

The U-V phase difference and U-W phase difference are phase differences from the U phase reference phase, so if we set an offset for the U phase in step 1, even if the U-V phase difference setting is 120°, the actual phase difference will be 150° (120° + 30°), which means that the phase difference setting will be offset from the actual phase difference. Likewise, the U-W phase difference setting will be offset from the actual phase difference.

The output state when the sequence is complete is the state specified in the last step. If the sequence ends with a U phase offset, as in this example, the U PH OFS icon will appear.

If the icon is displayed, be sure to press 1/2 and then U PHASE on the sequence screen to clear the offset.

Next, we will explain the phase sweeping of the V and W phases.

Specify the phase to sweep the V phase with the U-V phase difference.

Specify the phase to sweep the W phase with the U-W phase difference.

Below is an example of sweeping the V phase and an example of sweeping the U and V phases.

Phase sweeping the U and V phases

To sweep the U and V phases, you have to set the U phase offset. In step 1, to sweep the U phase from 0° to 30° and the V phase from 120° to 90°, even though the actual U-V phase difference is 60°, we set the U-V phase difference to 90° because this value must be set relative to the U phase reference phase when a U phase offset is set. The U-V phase difference setting is offset from the actual phase difference.

In step 1, we will suddenly change phases, and in step 2, we will sweep phases. For sudden phase changes, we normally do not use the U phase offset, but because we will use both sudden phase change and phase sweep in this example, we will set the sudden phase change using the U phase offset.

In step 1, we set the U-W line voltage to 70%.

We set the U and W phase voltages to 91.6 V (ramp off), the U phase (U phase offset) to 350° (360° - 10°), and the W phase (U-W phase difference) to 250° (240° + 10°). Because these will be sudden changes, the U and W phase ramp settings are set to off.

In step 2, the U-W line voltage is varied from 70% to 100% over the duration of the step (1 second).

We set the U and W phase voltages to 116.6 V and the voltage ramp to on.

To sweep the U phase clockwise to 0°, we set the U phase (U phase offset) to 0° and set the ramp to LAG.

To sweep the W phase counterclockwise to 240°, we set the W phase (U-W phase difference) to 240° and set the ramp to LEAD.

Use the screws that you removed in step 3 to fix the board in place in the panel.

8

If you installed the LAN interface board (LN05-PCR-LE), to change the host name, use the Web interface.

The factory default host name is “PCR-LE.” To access several PCR-LEs using host names, you need to change the host name.

For details on the Web interface, see “Interface Setup” in the Communication Interface Manual.

9

If you have installed the USB interface board (US05-PCR-LE), attach the ferrite core and the cable tie.

A ferrite core (96-01-0210) and cable tie (P4-000-551) are included with the USB interface US05-PCR-LE.

Attach the ferrite core at a position 10 cm or less from the USB port. Check that the ferrite core is locked securely in place.

Attach the cable tie to fix the position of the ferrite core.

Analog signal Interface boards (EX05-PCR-LE, EX06-PCR-LE)

By using one of the analog signal interface boards listed below, you can control PCR-LE2 Series AC power supply output with analog signals.

• EX05-PCR-LE simply amplifies the waveforms that it receives and outputs the result.

• EX06-PCR-LE varies the voltage of the output AC waveform (sine wave) on the basis of DC signals that it receives.

Insert the board in SLOT 3 on the rear panel.

For connections, see the EX05-PCR-LE/ EX06-PCR-LE Setup Guides.

Base Hold Angles (OP03-KRC)

These are used when you want to fix the PCR6000LE2, or PCR9000LE2 to a rack or the floor.

For details, see the OP03-KRC section in the OP03-KRC Manual.

When you are using these with the PCR6000LE2, or PCR9000LE2, you can use a coin or similar object to detach the caps that are included with the PCR-LE Series, then attach the base hold angles. Nuts that are included with the OP03-KRC will not be used.

The dimensions of the product when the base hold angles are attached to it are shown in the following figure.

Unit: mm

Control Panel Extension Cable (EC05-PCR)

This is an extension cable (2 m in length) that enables you to use the control panel while it is detached from the PCR-LE2 Series.

Maintenance

Cleaning the dust filter

Calibration

Cleaning the dust filter

A dust filter is installed on the inside of the louver on the front panel.

Periodically clean the filter to prevent clogging.

CAUTION

• If the dust filter is clogged, the product’s internal cooling capabilities will be reduced. This may lead to malfunction or the reduction of the product’s service life.

• When the PCR-LE2 Series is in operation, air is sucked through the dust filter to cool the inside of the device. If moisture is present in the dust filter, the temperature or humidity inside the PCR-LE2 Series increases and may cause malfunctions.

1

Detach all the louvers from the panel.

While using your fingers to push the lock lever under the detachment mark up, slide the entire louver to the right, and then pull the louver towards you to detach it.

2

Remove the dust filter from the inside of the louver.

3

Clean the dust filter.

Use a vacuum cleaner to dispose of the dust and foreign particles that are attached to the dust filter. If the filter is extremely dirty, clean it using a water-diluted neutral detergent and dry it completely.

4

Attach the dust filter to the louver.

The dust filter has a top side and a bottom side. The side that has sections cut out of it is the bottom side. Firmly attach the dust filter so that the louver’s tabs protrude out of the top of the dust filter.

5

Check the top and bottom parts of the louvers, and then attach all of them to the product.

Align the lock lever with the lock lever insertion hole. Align the hooks on the inside of the louver with the corresponding holes on the panel, and then slide the louver to the left to attach it.

Calibration

The PCR-LE2 is shipped after carrying out appropriate calibrations. We recommend periodic calibration to maintain the performance.

For calibration, contact your Kikusui agent or distributor.

Alarms and Trouble

Overview

The PCR-LE2 Series has the following protection functions. When a protection function is activated, an alarm (ALM-xx) or a trouble indication (TRBL-xx) is generated, and the output is turned off.

• Alarm

An alarm is generated by the PCR-LE2 Series to indicate that a protection function has been activated. Press ALM CLR (SHIFT+CLR) to clear the alarm, and then fix the problem that caused the alarm.

• Trouble

A trouble indication is generated by the PCR-LE2 Series when it is used improperly, when it suspects a malfunction, or when there is a possibility that it will be damaged. Turn the POWER switch off, wait at least 5 seconds, and turn it back on. If the same trouble indication occurs again, contact your Kikusui agent or distributor to request repairs.

If multiple alarms occur, only the first alarm will be displayed. To display the other alarms that are occurring, press ALM CHK (F5), and then turn the rotary knob.

Single-phase three-wire output, Three-phase output

"Na" is the number of power units in a group in which problems are not occurring. "Nb" is the total number of power units.

• Example 1: On the PCR6000LE2, when a problem is occurring in one unit in the M/U group and one unit in the S1/V group

Single-phase output:

Power that can be used = 6000*2/6 = 2000 W

Current that can be used = 60*2/6 = 20 A

Single-phase three-wire output, Three-phase output:

Available power of phase U = 6000*1/6 = 1000 [W]

Available current of phase U = 60*1/6 = 10 [A]

Available power of phase V = 6000*1/6 = 1000 [W]

Available current of phase V = 60*1/6 = 10 [A]

Available power of phase W = 6000*2/6 = 2000 [W]

Available current of phase W = 60*2/6 = 20 [A]

• Example 2: On the PCR6000LE2, when problems are occurring in two units in the M/U group

The power-saving function cannot be used because problems are occurring in all power units in the M/U group. The power-saving function cannot be used on the PCRLE2 Series if alarms are occurring on all units in any one of the groups.

Error Message

If you attempt to set a value that is not possible, the PCR-LE2 will generate a beep and an error message.

Error messages and remedies

Error Message

+102, "Operation denied (OUTPUT ON)"

Operation is denied because the OUTPUT is on.

+103 "Operation denied (PROTECTION)"

Operation is denied because a protection function is activated.

+104 "Operation denied (OUTPUT COUPLING)"

Operation is denied because the output mode is invalid.

+105 "Operation denied (OUTPUT OFF)"

Operation is denied because the OUTPUT is off.

+106 "Operation denied (TRIP DISABLE)"

Operation is denied because the action to perform when the current limit is exceeded is set to "not to turn the output off (DISABLE)."

+107 "Operation denied (RISE TIME/SIM/SEQ)"

Operation is denied because soft start, power line abnormality simulation, or sequence is in progress.

+108 "Operation denied (WIRING METHOD)"

Operation is denied because the wiring method (single-phase, three-wire; or three-phase) is invalid.

+109 "Operation denied (EXT.OUTPUT OFF)"

Operation is denied because the output has been turned off through external control.

+110 "Operation denied (EXT.SEQ.STOP)"

Operation is denied because a sequence is being executed or stopped through external control.

+111 "Operation denied (V-PROG)"

Operation is denied because the AC voltage output is being controlled with an external signal.

+112 "Operation denied (SOURCE)"

Operation is denied because the action is in conflict with the signal source setting.

+198 "Operation denied (ENTRY)"

Operation denied because the PCR-LE2 is waiting for an ENT key input.

+199 "Operation denied (BUSY)"

The operation is denied because the PCR-LE2 is busy.

+201 "Operation denied (FREQ)"

The sequence cannot be executed because there is a step whose frequency is outside its limits.

+202 "Operation denied (VOLT)"

The sequence cannot be executed because there is a step whose voltage is outside the voltage range or limits.

+203 “Operation denied (PHASE CHANGE)”

The sequence cannot be executed because there is a step whose trigger wait setting and sudden phase change setting are both turned on.

+301 "Setting Conflict (CONPENSATION)"

Cannot be set because the action is in conflict with the compensation setting.

+302 "Setting Conflict (CV RESPONSE)"

Cannot be set because the action is in conflict with the response setting.

+303 "Setting Conflict (RISE TIME)"

Cannot be set because the soft start output is in progress or the action is in conflict with the soft start setting.

+304 "Setting Conflict (SYNCRO)"

Cannot be set because the synchronization function is in use.

+305 "Setting Conflict (TRIP)"

Cannot be set because the action is in conflict with the action that is performed when any of the current limits is exceeded.
