Description
Shutdown alarm configurable on the input of IG-IOM/
IGS-PTM.
Warning alarm configurable on the input of IG-IOM/
IGS-PTM.
If the controller switches off during starting sequence
due to bad battery condition, it doesn't try to start again
and activates this protection.
Configurable Warning/Shutdown alarms on the inputs
of IL-NT.
Failure of the alternator to charge the battery.
If the red emergency stop switch is pushed or opened,
shutdown is immediately activated.
Water temperature is greater than Sd Water Temp set-
point.
Water temperature is greater than Wrn Water Temp
setpoint.
The generator frequency is out of limits given by Gen >f
and Gen <f setpoints.
Failure of the generator circuit breaker.
The generator current is unbalanced.
RTC backup battery is flat (low).
Oil pressure is smaller than Sd Oil Press setpoint.
Oil pressure is smaller than Wrn Oil Press setpoint.
The load is greater than the value given by Overload
setpoint.
The protection comes active if the speed is greater than
Overspeed setpoint.
Wrong checksum of parameters. Happens typically
after downloading new firmware or changing of the
parameter. The controller stays in INIT mode. Check all
parameters, write at least one new parameter.
Failure of the magnetic pick up sensor for speed mea-
surement.
Shutdown alarm in case of lost connection to IOM/IGS-
PTM module.
The protection is active if the output Sprinkler is closed.
Unit did not start.
Unit did not stop.
Battery voltage is out of limits given by Batt Undervolt
setpoints.
During starting of the engine, when the RPM reaches
the value of Starting RPM setpoint, the starter is
switched off and the speed of the engine can drop
under Start RPM again. Then the Underspeed protec-
tion becomes active. Protection evaluation starts 5 sec-
onds after startup.
