Centralized alarm
pre-assigned to terminals 47/48
This relay is enabled when a centralized alarm is issued. An external horn, buzzer, or beacon may be
operated by this relay output during a fault condition. Pressing the "RESET" button will reset the re-
lay. The relay will re-energize if another alarm condition is detected. The centralized alarm is issued
for fault classes F1 through F3.
Command: close GCB
Terminals 14/15
The "Command: close GCB" relay issues the signal for the GCB to close. This relay may be confi-
gured for a momentary pulse to operate an external holding coil for the GCB or for a continuous cur-
rent (Parameter 114).
If th
e relay is configured for a momentary pulse, the relay will energize for the time configured in
"Synchronize time pulse" (Parameter 119).
If th
e relay is configured for a constant current, the relay will energize and remain energized when the
discrete input "Reply: GCB is open" de-energizes and the generator and busbar voltages are identical.
If an F2 alarm condition is detected, the generator load is reduced and the GCB is opened when the
measured power is less than 3% of rated or the time configured for "Add on/off max. time" (Para-
m
eter 112) expires, which ever occurs first. If an F3 alarm condition is detected, this relay de-
energizes immediately.
Command: open GCB
Terminals 41/42
The "Command: open GCB" relay issues the signal to open the GCB. After the open command has
been issued this relay is de-energized.
[GCP-32] Command: close MCB
Terminals 16/17
The "Command: close MCB" relay issues the signal for the MCB to close. This relay is a momentary
pulse and must be used with an external holding coil for the MCB.
[GCP-32] Command: open MCB
Terminals 39/40
The "Command: open MCB" relay issues the signal to open the MCB. After the open command has
been issued this relay is de-energized.
Relay Manager
Terminals 74 to 83, 37/38, 47/48
The "Relay Manager" (Parameter 250) permits specific logical functions to be assigned to specific re-
lay outputs.
Default values:
•·Relay 1 to 5 = relay number (e.g. relay 1 = alarm class F1, relay 2 = alarm class F2, etc.)
•·Relay 6 = Ignition / preheating
•·Relay 7 = Centralized alarm
Refer to Appendix B for a description of the Relay Manager functions.
