STOP TEST MANUAL AUTOMATIC
CLOSED TRANSIT.: Breaker logic "Closed transition / make-before-brake / overlap synchronization"
The MCB and the GCB are synchronized, in order to avoid a dead busbar in this breaker logic mode. Immediately after the
synchronization of one breaker, the other is opened. Continuous mains parallel operation is not possible.
The GCB is
opened; the MCB
is not operated.
The GCB and the MCB are not
operated.
Exception
: Load test by actuating
the "GCB ON" push-button.
Termination of the load test via
the "GCB OFF" or "MCB ON"
push-button(s).
Emergency power:
Automatic
closing of the GCB. If there is a
dead busbar and terminal 53 "En-
able MCB" is energized, the
MCB will be closed.
Synchronization of either the ge-
nerator or the mains can be in-
itiated by pressing the "GCB
ON" or "MCB ON" push-button.
The GCB is synchronized via an
add-on request. After the GCB
closes the MCB is opened. Fol-
lowing the shed-off request being
issued, the MCB is synchronized
and closed. After the MCB has
closed the GCB is opened.
Emergency power:
The emergen-
cy power operation is terminated
following the expiration of the
mains settling time and the MCB
synchronizing to the generator.
The MCB closes and the GCB
opens immediately afterwards.
INTERCHANGE: Breaker logic "Soft loading / interchange synchronization"
The MCB and the GCB are synchronized, in order to avoid a dead busbar in this breaker logic mode. The operation of a
breaker under load is avoided by utilizing the ability to soft load. Continuous mains parallel operation is not possible with this
breaker logic. Following the shed-off request, the MCB synchronizes and closes, the generator soft unloads to the mains and
the GCB opens. After the GCB is open the engine is stopped following the expiration of the configured cool down period.
The GCB is
opened; the MCB
is not operated.
The GCB and the MCB are not
operated.
Exception
: Load test by actuating
the "GCB ON" push-button.
Termination of the load test via
the "GCB OFF" or "MCB ON"
push-button.
Emergency power
: Automatic
closing of the GCB. If there is a
dead busbar and terminal 53 "En-
able MCB" is energized, the
MCB will be closed.
Synchronization of either the ge-
nerator or the mains can be in-
itiated by pressing the "GCB
ON" or "MCB ON" push-button.
Via an engine request, the GCB
is synchronized and the generator
power is increased. The MCB is
then opened. Following the dis-
abling of the engine request, the
MCB is reverse synchronized and
the GCB is then opened.
Emergency power:
The emergen-
cy power operation is terminated
following the expiration of the
mains settling time. The MCB
closes, the load is transferred,
and the GCB opens.
