GCB Off Coil
The output deactivates Generator Circuit Breaker coil.
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.
Breaker Trip
The output is designated for auxiliary breaker tripping.
The output closes if:
x any BOC or SD alarm appears
x EF PROT TEST binary input is activated
x EF Prot Test command (in Man Operations setpoints group) is activated
x controller buttons’ combination for Eart Fault Protection Test is used
The output opens if:
x No BOC and SD alarms are active and
x FAULT RESET is pressed
Hint:
In case there is a SD (caused by generator protections - like overvoltage, under voltage, under
frequency, etc.), when the gen-set stops even in case of override, it does not issue the Breaker Trip
command = Breaker Trip output is not activated (if you use it for a breaker, the breaker stays closed).
In contrary “GCB open output” is in such case activated (and when used for breaker control, then GCB
is opened).
Ready
The output is closed if following conditions are fulfilled:
x Gen-set is not running and
x No Shutdown protection is active
x Controller is not in OFF Mode
Ready To AMF
The output is active, if the controller is able to start the engine (the output Ready is active) or engine is
already running and simultaneously the controller is in AUT 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.
Running
The output closes if the engine is in Running state.
Cooling
The output closes when gen-set is in Cooling state.
Supplying Load
Closed when the generator current is > 0,5% of the CT ratio.
