Binary output: InMainsParal
This LBO indicates that controller (or logical group, which the controller is member
of) is connected to the mains. It means that there exists a way across MCB (IM-
NT-MCB application) or MCB+MGCB (IM-NT-MGCB application) to the controller.
It is possible to configure this signal as MCB feedback of the controller, what can
be useful for complicated applications with higher amount of mains.
NOTE:
This signal works correctly only if IM-NT is used as the MCB/MGCB control
device.
Binary output: Engines swapped
This output is activated by the master controller for 100 ms pulse when the priority
of two gen-sets was swapped by the Running hours equalization function.
Binary output: Neutral CB C/O
This output is intended for control of the neutral contactor. The output provides
continuous signal while the neutral contactor has to be closed. Use the input
NeutralCB fdb for the neutral contactor feedback.
Response time of the contactor must be less than 400ms. If the contactor does
not respond to an open or close command within this time, the alarm Wrn NCB fail
is issued.
NOTE:
Learn more about neutral contactor in the description of the setpoint #Neutral
cont..
Binary output: PeriphCommErr
The output is closed while there is an error in the communication with any
peripheral unit (e.g. IS-AIN8, IGS-PTM, ...).
Binary output: CtrlHeartBeat
The output provides alternating signal with rate 500ms active / 500ms inactive
while the controller is operational, i.e. it has passed all checks after startup and
no failure was detected.
If the output does not provide the alternating signal it may indicate following:
• controller is switched off or
