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.

 

Item	Title	Description
ON	Sleep Timer	The sleep function turns on. Sets the time that elapses before the PCR-LE2 Series enters sleep mode (1 min to 60 min).
OFF		The sleep function turns off.
EXEC	--	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).

 

Item		Title	Description
POW SAV		Power Save	Sets the anticipated maximum power*1 (3 kVA to the rated output capacity; resolution: 3 kVA). Example: If the anticipated maximum power on a PCR9000LE2 is 4.5 kVA, set this to 6 kVA.
	U*2	U Power Save	Sets the anticipated maximum power of U phase (1 kVA to the rated output capacity; resolution: 1 kVA)
	V*2	V Power Save	Sets the anticipated maximum power of V phase (1 kVA to the rated output capacity; resolution: 1 kVA)
	W*3	W Power Save	Sets the anticipated maximum power of W phase (1 kVA to the rated output capacity; resolution: 1 kVA)

*1. During single-phase output

*2. During single-phase three-wire output or three-phase output

*3. During three-phase output

Turn the POWER switch off and on to enable the setting.

To clear the power-saving function, set the MAX setting to the rated output capacity.
