GCB OFF Coil
The output deactivates Generator Circuit Breaker coil. The impulse length is double of GCB Delay
timer.
GCB UV Coil
The output controls Generator Circuit Breaker coil after voltage drop-out. The impulse length is double
of GCB Delay timer.
MCB Close/Open
The output controls the mains circuit breaker.

:
Supposed time to close (reaction time) of MCB is depend of breaker type and related to setpoint GCB
Delay.
MCB ON Coil
The output activates Mains Circuit Breaker coil. The impulse length is double of MCB Delay timer.
MCB OFF Coil
The output deactivates Mains Circuit Breaker coil. The impulse length is double of MCB Delay timer.
MCB UV Coil
The output controls Mains Circuit Breaker coil after voltage drop-out. The impulse length is double of
MCB Delay timer.
Fault Reset
The output is a copy of Fault Reset button on controller and binary input
FaultResButton
.
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
This output is activated when the controller is in AUT mode and no Trip alarm is active or unconfirmed.
It remains active when the engine is running.
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.
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.
