11.2.8.3 Setpoint: MCB close del
This setpoint determines the delay for MCB closing after mains is restored.
This delay is considered if no gen-sets are running (i.e. output Sys start/stop
not active).
NOTE:
This setpoint is active in OFF and AUT mode.
11.2.8.4 Setpoint: MCB opens on
MAINSFAIL, GEN RUNNING, BUS VOLTAGE [-]
This setpoint allows adjusting of condition of MCB opening after mains fail.
Controller opens the MCB when Mains fail is detected
(24 VDC controlled circuit breaker or contactor
expected).
Controller opens the MCB only after at least one gen-
set starts, i.e. the generator voltage is present to
open the MCB (230 VAC controlled breaker
expected). In OFF mode, this means MCB stays
closed all the time, regardless of the mains condition.
Controller opens the MCB only after there is voltage
present on the bus to open the MCB (230 VAC
controlled breaker expected). In OFF mode, this
