This input is used for connection of the normally open feedback contact from the
Neutral contactor. If the input is active, the controller will consider the neutral
contactor as closed and vice versa. See also description of the setpoint #Neutral
cont..
Binary input: CylDifEvalBlk
This input is used to disable temporarily evaluation of the alarms caused by
cylinder temperatures deviations.
NOTE:
For IS-NT only.
Binary input: ECU StoppedEng
When this input is activated, the genset will be stopped immdiately without
unloading and cooling phase, however no alarm will be issued.
This input is intended for situations, where the genset is controller by an ECU or
other device which also includes engine protections and can stop the engine itself.
In such case the controller would issue an Underspeed alarm. Connecting this
input to an appropriate ECU output, which provides information, that the engine
has been stopped by the ECU, prevents the controller from issuing the
underspeed alarm.
Binary input: CtrlHBeat sens
This input is used at a redundant controller to sense the "heart beat" from the
main controller. The input is to be connected to the output CtrlHeartBeat of the
main controller.
If the redundant controller does not sense the heart beat from the main one, it will
activate the binary output CtrlHBeat FD, which has to be wired such a way, that it
disconnects the dead main controller from the genset, connects the redundant
controller instead and activates it.
NOTE:
Learn more about redundancy in separate chapter Redundant controllers.
Binary input: Nominal speed
Use this input to bypass the idle phase of the start-up procedure.
NOTE:
The input is especially designed for shortening of the start-up procedure when the
gen-set is starting to an AMF operation.
