Overview GCP-31
STOP TEST MANUAL AUTOMATIC
Breaker logic: EXTERNAL: (External)
GCB is primarily operated by an external control such as a PLC. The GCB may be operated through the GCP only if the
MANUAL operation mode has been enabled when this breaker logic is used. In a mains parallel operation, decoupling from
the mains is carried out via the GCB in the event of a mains failure. The GCB will not automatically close in an emergency
power operation.
The GCB is
opened.
The GCB is not operated.
Exception:
The GCB is opened to
decouple from the mains.
The GCB can be manually
opened and closed without syn-
chronization. The GCB is opened
to decouple from the mains.
The GCB is opened if the genset
is stopped or if decoupling from
the mains but will not close if the
engine is started unless given a
close command from an external
controller. The GCB is opened
only if decoupling from the
mains and is never closed unless
given a close command from an
external controller.
Breaker logic: PARALLEL: (Mains parallel)
The GCB is synchronized to permit continuous mains parallel operation or paralleling multiple generators in an isolated ap-
plication. This mode may also be used to operate a single isolated generator.
The GCB is
opened.
The GCB is not operated.
Exception:
Pressing the "GCB
ON" push-button enables load
tests. Pressing the "GCB OFF"
push-button terminates the load
test.
Emergency power:
If a mains
failure occurs while in the TEST
mode, the control can be confi-
gured to open the GCB to de-
couple from the mains.
Synchronization of either the ge-
nerator can be initiated by press-
ing the "GCB ON" or push-
button. This will enable a mains
parallel operation.
The GCB is synchronized via an
add-on request and a mains paral-
lel operation is performed. When
an add-off request is issued, the
generator sheds load and opens
the GCB and the engine is shut
down following completion of
the configured cool down period.
