Note: A control power supply capacity greater than the rated capacity is required when the Digital Panel Meter is turned ON. Do not for-
get to take this into consideration when using several Digital Panel Meters. When power is supplied, all indicators will light and
outputs will be OFF. When using startup compensation time operation, the display will read “00000” and all outputs will be OFF.
