After opening the breaker, there is internal delay for another closing of breaker. Delay is 6 seconds - 5
seconds for OFF coil and 1 second for UV coil. After these 6 seconds, breaker can be closed again. For
opening of breaker there is no delay.
Breaker control outputs
Close/Open
An output for control of a contactor. Its state represents the breaker position requested by the
controller. The breaker must react within 2 seconds to a close or open command, otherwise
an alarm is issued.
ON coil
An output giving a 2 second pulse in the moment the breaker has to be closed. The output is
intended for control of close coils of circuit breakers.
OFF coil
An output giving a pulse in the moment the breaker has to be opened. The pulse lasts until
the feedback deactivates, but at least for 2 seconds. The output is intended for control of
open coils of circuit breakers.
UV coil
The GCB UV coil output is active the whole time the gen-set is running (not in idle or cooling).
The MCB UV coil output is active when the controller is switched on. The output is
deactivated for at least 2 seconds in the moment the breaker has to be switched off. The
output is intended for control of undervoltage coils of circuit breakers.

Breaker fail detection
Breaker fail detection is based on binary output breaker close/open comparing with binary input breaker
feedback.
IMPORTANT: It is necessary to configure breaker feedback to use this function.
IMPORTANT: Also it is possible to use breakers without feedbacks. In this case there is no check
of breaker real state.
There are three different time delays for breaker fail detection – see following diagrams.
