Dwell time, the circuit breaker closing command is issued.

This setpoint adjusts the end point of the gen-set unloading ramp, i.e. power level
at which the GCB is opened. If this level is not reached within time period adjusted
by setpoint BCB open del the GCB is then opened regardless of the gen-set
power.
NOTE:
The speed of the ramp is adjusted by the setpoint Load ramp in subordinated gen-
sets.
This setpoint adjusts the maximum duration of the gen-set unloading ramp. If the
end point of the ramp (BCB open level) is not reached within time period adjusted
by this setpoint the GCB is then opened regardless of the gen-set power.
NOTE:
The speed of the ramp is adjusted by the setpoint Load ramp in subordinated gen-
sets.
1 .. 1800, NO TIMEOUT [s]
