Gen params OK
The output is copy of generator status LED on controller front panel. The output is closed if gen-set is
running and all generator electric values are in limits and no 2
nd
level alarm is active (when only 1
st
level
alarm is active, the output is closed).
Hint:
Use this output for switching on of auxiliary device (e.g. cooling pump) driven from generator voltage
independently on the GCB status.
Bus params OK
The output is copy of bus status LED on controller front panel. The output is closed if bus electric values are
in limits.
In synchronism
The output closes during synchronizing if all matching conditions are fulfilled. It opens if corresponding
breaker is closed (xCB status output get active).
Hint:
Synchronizing matching conditions:
- Slip frequency < 0,25 Hz
- Gen to Mains/Bus voltage phase shift within Sync/Load ctrl:Phase window
- Gen and Mains/Bus voltages within Sync/Load ctrl:Voltage window
- Sync/Load ctrl:Dwell time elapsed
GCBCloseEna
The output can be used for safe “by hand” GCB closing. The output activity is based on condition “In
synchronism” OR “Dead bus” (any bus phase voltage is below 15 VAC). Output is opened when GCB is
closed.
