Alarm
The output closes if :
• any alarm comes up or
• the gen-set malfunctions
The output opens if
• FAULT RESET is pressed
The output closes again if a new fault comes up.
^GCB Close/Open
The output controls the generator circuit breaker.
Hint:
Supposed time to close (reaction time) of GCB is 0,1 sec.
^Ready to AMF
The output is active, if the controller is able to start the engine (the output Ready to run is active) or
engine is already running and simultaneously the controller is in AUTO Mode.
Ready
The output is closed if following conditions are fulfilled:
• Gen-set is not running and
• No Shut down is active
• Controller is not in OFF Mode
Ready To Load
The output is closed if gen-set is running and all electric values are in limits no alarm is active - it is
possible to close GCB or it is already closed. The output opens during cooling state.
AL Mains Fail
Output closes if the mains over/under voltage alarm, voltage asymmetry alarm or mains over/under
frequency alarm activates.
The output opens, if
• alarm is not active and
• FAULT RESET is pressed
Not in AUT
The output is closed, if MAN Mode is selected.
*ECU PowerRelay
The output closes at the beginning of prestart and opens if the engine shall be stopped. The
communication failure with ECU is not evaluated while the output is not active even if it is not
configured. It means that if communication with ECU fails during engine stop for example (ECU
PowerRelay output would be closed if configured) the controller doesn't issue any related alarms.
Battery Flat
Output closes when IL-NT performs reset during start procedure (probably due to weak battery) or
when battery under voltage warning appears.
The output opens, if
• alarm is not active and
• FAULT RESET is pressed
Glow Plugs
The output closes prior to the engine start (by Prestart Time) and opens at the beginning of cranking
time. In case of repeated crank attempts the output closes always prior to the other engine start
attempts (by Prestart Time) and is opened during crank attempts.
