STOP
The GCB is opened; the MCB is operated
depending on the setting of "Enable MCB"
(parameter 12923 Ä p. 206).
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 12923 Ä p. 206).

opened. Following the shed-off request
being issued, the MCB is synchronized
and closed. After the MCB has closed the
GCB is opened.
Emergency power: The emergency power
operation is terminated following the expi‐

MCB synchronizing to the generator. The
MCB closes and the GCB opens immedi‐
ately afterwards.
Via an engine request, the GCB is
synchronized and the generator power is
increased. The MCB is then opened. Fol‐
lowing the disabling of the engine request,
