Manual 37128A GCP-20 Series - Genset Control
Page 108/190 © Woodward
Parameter 130
Supervision MCB
ON
[GCP-20/22] only
MCB monitoring ON/OFF
ON................Monitoring of the MCB is performed except when the breaker logic
is configured as "EXTERNAL". If the breaker cannot be closed after
five attempts, an alarm message is issued. The relay with the parame-
ter 75 is energized. Following the issuing of the alarm message, fur-
ther attempts are made to close the MCB. If load sharing has been
enabled (
Parameter 77) the closing command to the breaker is can-
celled if an alarm is issued so that another control may close its
breaker. If a "Reply: MCB is open" message is not detected
2 seconds after a "Command: open MCB" pulse is issued, an alarm
message is issued. The relay with the parameter 77 is energized.
Issuing of class F1 alarm
OFF..............No MCB monitoring is performed.
Mains Decoupling
NOTE
If the mains monitoring (frequency and voltage) is disabled, no mains decoupling is performed.
Parameter 131
Mains decoupling
via ---
Decoupling from the mains via ... MCB/GCB
In case of a response of the mains monitor, a decision may be made as to which
power circuit breaker has to be opened if an alarm occurs. If an isolated operation
may not be carried out with the generator, the power circuit breaker (GCB) must be
opened. If an isolated isolation is allowed, the mains circuit breaker (MCB) may be
opened.
Parameter 132
Switch MCB in
STOP mode OFF
from V1-0700
Operate MCB in STOP operation mode YES/NO
ON................The MCB will be operated by the GCP in STOP mode (the busbar
will be closed onto the mains if the controller is changed into this
STOP mode). It is necessary that "Enable MCB" (terminal 53) be en-
ergized as well.
OFF..............The MCB will not be operated by the GCP in STOP mod (the busbar
will not be connected or remains unconnected if the control unit is
changed into STOP mode).
