synchronized and closed. After the
MCB has closed the GCB is opened.
Emergency power: The emergency
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
operated depending on the setting of
"Enable MCB" (parameter
).
Synchronization of either the
generator or the mains can be
initiated 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 disabling of the engine
request, the MCB is reverse
synchronized and the GCB is then
opened.
Emergency power: The emergency
power operation is terminated
following the expiration of the mains
settling time. The MCB closes, the load
is transferred, and the GCB opens.

PARALLEL: Breaker logic "Mains parallel"
This operation mode may be used both in the case of an islanded system, an islanded parallel system, and a system that
is operated in mains parallel.
The GCB is opened.
Mains parallel operation can be
performed via the "GCB On" push-
button.
The GCB is synchronized via an add-on
request and mains parallel operation
is performed.
When a shed-off request is issued, the
generator sheds load, the GCB is
opened, and the engine is shut down
following the configured cool down
period.
