Binary input: GCB fdb neg
Related FW 3.0
Description This input is used for connection of the normally closed feedback contact from
the generator circuit breaker or contactor. This input is optional and if it is
configured, it must be always in inverse position to the normally open input
feedback. Maximal allowed time the both inputs are in the same position is
500ms, after this time the alarm GCB Fail is issued.
Binary input: MCB fdb neg

Description This input is used for connection of the normally closed feedback contact from
the mains circuit breaker or contactor. This input is optional and if it is configured,
it must be always in inverse position to the normally open input
Maximal allowed time the both inputs are in the same position is 500ms, after this
time the alarm MCB Fail is issued.
Binary input: Emerg. manual

Description This input is designed to allow the gen-set to be controlled externally, not by the
controller.
This feature is especially designed for marine gen-sets, which are supposed to be
started manually as the controller has no power supply before the gen-set is
started. It may be also useful in case of testing the gen-set or in case of a failure,
which does not allow the gen-set to be controlled by the controller, but the gen-set
itself is stays operational. This function is also used in case of
disable redundant controller.
The controller behaves following way:

If the input is active during synchronizing, the controller will keep the
genset synchronized without issuing the GCB closing command until the
input is deactivated or Sync timeout
If the input is active and the GCB button is pressed in MAN mode to close
the GCB to dead bus, the GCB will not be closed until the input is
deactivated and the GCB button pressed again.
If the input is active and the GCB is to be closed to dead bus
automatically, the GCB will not be closed until the input is deactivated.

Stops all functions regarding the gen-set control, deactivates all outputs
related to it. The complete list of effected logical binary outputs is at the
bottom.
Stop Fail alarm is not beeing evaluated and stop solenoid is not activated
if nonzero speed is detected.
Voltage, current, power and other electric measurements are active.
When the input is deactivated, the controller takes control over the gen-
set according to the situation in which the gen-set was in the moment of
is elapsed.
