Description
Only applicable for application modes
The "Command: close GCB" output issues the signal for the GCB
to close. This relay may be configured as an impulse or constant
output signal depending on parameter
Impulse
If the output is configured as "Impulse", the discrete output will
enable for the time configured in parameter
external holding coil and sealing contacts must be installed into
the GCB closing circuit if this discrete output is configured for an
impulse output signal.
Constant
If the relay is configured as "Constant", the relay will energize and
remain enabled as long as the discrete input "Reply GCB"
remains de-energized and the generator and busbar voltages are
identical. If a class C or higher alarm occurs, this discrete will dis‐
able and the GCB will open immediately.
Not applicable for application mode
The parameter
If this output is configured as "N.O.", the relay contacts close
resulting in the GCB opening circuit energizing.
If this output is configured as "N.C.", the relay contacts open
resulting in the GCB opening circuit de-energizing.
If the controller is configured for the breaker application "None",
this relay is freely configurable.
Application mode
The open GCB command remains enabled until the GCB is man‐
ually closed and the discrete input "Reply GCB" is energized. The
open GCB command will be issued when a fault condition or an
engine shut down occurs.
Application mode
The controller enables the open GCB command when the GCB is
to be opened for switching operations. If the discrete input "Reply
GCB" is energized, the open GCB command will be disabled.
Only applicable for application mode
The discrete output "Command: close MCB" is an impulse output
signal.
This discrete output is enabled for the time configured in param‐
eter 3417 Ä p.
An external holding coil and sealing contacts must be utilized with
the MCB closing circuit.
