Breaker Monitoring
Upon CLOSING - The GCP monitors the GCB and/or the MCB to ensure that the respective breaker has closed
if "GCB monitoring" (Parameter 130) and/or "MCB monitoring" (Parameter 131) have been configured "ON"
unl
ess the breaker logic is configured "EXTERNAL" (Parameter 111). If the breaker has not closed after five at-
tem
pts, a class F1 alarm is issued. If a relay has been assigned relay manager functions 74 or 75, it will be ener-
gized. A breaker is considered as closed, if the reply is present for 5s. This resets the internal counter.
Upon OPENING - The GCP-30 monitors the GCB and/or the MCB to ensure that the respective breaker has
opened if "GCB monitoring" (Parameter 130) and/or "MCB monitoring" (Parameter 131) have been configured
"ON". If the GCP-30 does not receive a reply that the respective breaker has opened within 2 seconds of the
open com
mand being issued, an F1 class alarm is issued. If a relay has been assigned relay manager functions 76
or 77, it will be energized.
Parameter 130
Supervision GCB
ON
GCB monitoring ON/OFF
ON ................ Monitoring of the GCB 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 and the relay assigned relay
manager function 75 is energized. The GCP will continue to attempt
to close the GCB after the alarm has been issued unless load sharing
(Parameter 90) has been enabled. If load sharing has been enabled
(Parameter 90) and several GCPs are connected to the CAN bus, the
breaker cl
ose command is cancelled upon issuing of the alarm so that
another GCP may start up and close its breaker. If a "Reply: GCB is
open" message is not detected 2 seconds after a "Command: open
GCB" pulse is issued, an alarm message is issued and the relay as-
signed relay manager function 77 is energized.
Issuing of F1 class alarm
OFF .............. No GCB monitoring is performed.

[GCP-32]
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 and the relay assigned relay
manager function 74 is energized. The GCP will continue to attempt
to close the MCB after the alarm has been issued unless load sharing
(Parameter 90) has been enabled. If load sharing has been enabled
(Parameter 90) and several GCPs are connected to the CAN bus, the
closing com
mand to the breaker is cancelled if an alarm is issued so
that another GCP 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 and the relay assigned re-
lay manager function 76 is energized.
Issuing of F1 class alarm
OFF .............. No MCB monitoring is performed.
