13.2.1.3 Binary input: MCB fdb neg
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
MCB feedback. Maximal allowed time the both inputs are in the same
position is 500ms, after this time the alarm MCB Fail is issued.
13.2.1.4 Binary input: MGCB feedback
This input is used for connection of the normally open feedback contact from
the master generator circuit breaker or contactor. If the input is active, the
controller will consider the MGCB as closed and vice versa.
If the feedback does not respond to a change of the control output
MGCB close/open within 2s, the alarm MGCB Fail will be issued.
If the feedback changes it's position unexpectedly without any
command given by the control output, the alarm MGCB Fail will be
issued immediately.
NOTE:
This input is obligatory.
13.2.1.5 Binary input: MGCB fdb neg
This input is used for connection of the normally closed feedback contact
from the master 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 MGCB feedback. Maximal allowed time the both inputs are in the
same position is 500ms, after this time the alarm MGCB Fail is issued.
13.2.1.6 Binary input: Rem Start/Stop
If the input closes (AUT mode only), the controller activates the binary output
Sys start/stop in order to start the gen-set group (to enable the start setpoint
ParallelEnable should not be set to NO). In MGCB application, the MGCB
can be closed before the output activation (see setpoint description
MGCBparalClose).
