Binary inputs – list
Rem Start/Stop
External request for engine run. AUT mode only.
NOTE:
If the binary input Rem Start/Stop is active and mains failure occures, the MCB breaker opens, and
after AMF Settings: Trans Del delay the GCB breaker is closed. Once the mains is OK, the AMF
Settings: MainsReturnDel delay elaspes and the GCB breaker is opened. Then after AMF Settings:
Trans Del delay is MCB breaker closed. Gen-set remains running as long as Rem Start/Stop is active.
See AMF time chart for more details.

MCB Feedback
This input indicates whether MCB is closed or opened.

This iinp s creted mainly for cascading applications, where slave controllers do not have usually
Mains and Gen-set voltage measuring inputs connected to the repspective power sources.Then this
binary input tells the controller if Mains is healthy to be able to respond to Mains failure.
