GCB UV Coil
The output controls Generator Circuit Breaker coil after voltage drop-out.
MCB Close/Open
The output controls the mains circuit breaker.
MCB ON Coil
The output activates Mains Circuit Breaker coil.
MCB OFF Coil
The output deactivates Mains Circuit Breaker coil.
MCB UV Coil
The output controls Mains Circuit Breaker coil after voltage drop-out.
Gen Healthy
The output is a copy of generator status LED on IA-NT front panel. The output is closed if gen-set is
running and all gen-set electric values are in limits.
Ready To AMF
The output is active, if the controller is able to start the engine and simultaneously the controller is in
AUT Mode.
Ready
The output is closed if following conditions are fulfilled:
•
Gen-set is not running and
•
Controller is not in OFF Mode
Ready To Load
The output is closed if gen-set is running and all electric values are in limits and no alarm is active - it
is possible to close GCB or it is already closed. The output opens during cooling state.
Cooling
The output closes when system is in Cooling state.
Mains Healthy
The output is copy of mains status LED on IA-NT front panel. The output is closed if mains voltage
and frequency are within limits.
AL Gen >V
The output closes if the generator overvoltage shutdown alarm activates.
The output opens, if
•
alarm is not active and
•
FAULT RESET is pressed
AL Gen <V
The output closes if the generator undervoltage shutdown alarm activates.
The output opens, if
•
alarm is not active and
•
FAULT RESET is pressed
AL Gen Volts
The output closes if the generator over/under voltage alarm or voltage asymmetry alarm activates.
The output opens, if
