CHARGING ALTERNATOR FAULT.  It is possible to program the stop; by factory default it is programmed to stop.

NUMBER OF ATTEMPTS TO START.  10 attempts to start can be programmed. (Failure to start).

LOW OIL PRESSURE WARNING. (The pressure measured by the pressure transmitter). This is programmed as notification and does 

not stop the engine. (The low pressure detected by the pressure switch causes the engine to stop).

STARTING OF GENERATOR SET WITH BATTERY WITH LOW CHARGE.  (With control unit in automatic mode). Starts or stops the 

generator set depending on the voltage measured at the battery terminals.

FUEL RESERVE.  

Does not stop the engine.

FUEL FINISHED

.  It is possible to program the stop; by factory default it is programmed to stop.

INTERVENTION DUE TO ENGINE OVERTEMPERATURE. The temperature is measured by the (TEMPERATURE) TRANSMITTER and is 

programmable. The protection device can be set on two levels and intervenes when these are exceeded. The warning level is 

programmed only as notification, the other level is programmed to stop the engine (the overtemperature is also detected by the 

thermostat that always causes the engine to stop).
