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 acti-
vates 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, shut-
down is immediately activated.
Water temperature is greater than Sd Water Temp setpoint.
Water temperature is greater than Wrn Water Temp setpoint.
The generator frequency is out of limits given by Gen >f and
Gen <f setpoints.
Fuel level is smaller than Sd Fuel Level setpoint (5%). (Not
available on MLG, MLT or MTT units.)
Fuel level is smaller than Wrn Fuel Level setpoint (15%). (Not
available on MLG, MLT or MTT units.)
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 measure-
ment.
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 set-
points.
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 protection becomes active. Protection
evaluation starts 5 seconds after startup.
The generator voltage is out of limits given by Gen <V and
Gen <V setpoints.
