Use this input for indication, whether the generator circuit breaker is open or closed.
If the feedback is not used, connect this input to the output GCB CLOSE/OPEN
MCB Feedback
This input indicates whether MCB is closed or opened.
Emergency Stop
If the input is opened, the stop signal for the gen-set is sent and the MCB and GCB are opened. Input
is inverted (normally closed) in default configuration.
Access Lock
If the input is closed, no setpoints can be adjusted from controller front panel and gen-set mode (OFF-
MAN-AUT-TEST) cannot be changed.
N

:
Access Lock does not protect setpoints and mode changing from LiteEdit. To avoid unqualified
changes the selected setpoints can be password protected. Also the button Fault reset, is not blocked
at all and buttons Start and Stop in MAN mode are not blocked.
