2.1 LED Display

1) Load on inverter [ LOAD ON INVERTER ](green)

Illuminates when power is supplied from inverter to the critical load. (Indicates the state of inverter transfer switch "52C".)

2) Battery operation [ BATTERY OP. ](yellow)

Illuminates when power is supplied from batteries following a power failure.

3) Load on bypass [ LOAD ON BYPASS ](green)

Illuminates when power is supplied to load devices by static bypass.

4)Overload [ OVERLOAD ](red) Illuminates in overload condition.

5)LCD fault [ LCD FAULT ](red) Illuminates when an error occurs.

6)UPS fault [ UPS FAULT ](red) [Annunciater: intermittent or constant tones] Illuminates when an error occurs in the system. In this case, the details of the error are indicated on the display panel.
