Starter motor Energise starter motor.
Fuel solenoid valve Energise the fuel solenoid valve.
Global alarm Output activated in the presence of any alarm with the Global alarm property activated.
Mechanical fault Output activated if at least one alarm with this property is enabled.

Siren Powers the acoustic warning siren.
Decelerator Commands deceleration in the start phase. Energised as soon as the engine starts, for the set maximum
duration.

Stop magnet Output energised to stop the engine.
ctivation of glow plug pre-heating prior to engine start.
Gas valve Controls the gas delivery solenoid valve. Opens after a delay with respect to the energisation of the starter motor

to start gas fuelled engines. The gasoline
start relay is energised in parallel with the gas

Alarms
CODE DESCRIPTION DESCRIPTION OF ALARM
A01 Engine temperature pre-alarm (analog sensor) Occurs if engine temperature rises above the pre-alarm threshold set in P09.05.
A02 Engine temperature high (analog sensor) Occurs of engine temperature rises above the alarm threshold set in P09.06.
A03
nalog temperature sensor fault Occurs if the resistive temperature sensor is in open circuit (disconnected).
A04 Engine temperature high (digital sensor) Occurs if engine overtemperature is signalled by activation of the digital input programmed for this function.
A05 Engine temperature low (analog sensor) Occurs if engine temperature falls below the alarm threshold set in P09.07.
A06 Oil pressure pre-alarm (analog sensor)
Occurs if engine oil pressure falls below the pre-alarm threshold set in P08.05.
A07 Oil pressure low (analog sensor) Occurs if engine oil pressure falls below the alarm threshold set in P08.06.
A08
nalog pressure sensor fault Occurs if the resistive pressure sensor is in open circuit (disconnected).
A09 Oil pressure low (digital sensor) Occurs if low oil pressure is signalled by activation of the digital input programmed for this function.
A10 Digital pressure sensor fault Occurs if the engine has stopped for over one minute, but the oil pressure sensor has not closed its contacts to
signal no oil pressure. It is assumed that the sensor is disconnected.
A11 Fuel level pre-alarm (analog sensor) Occurs if fuel level falls below the pre-alarm threshold set in P10.04.
A12 Fuel level low (analog sensor) Occurs if fuel level falls below the alarm threshold set in P10.05.
nalog fuel level sensor fault Occurs if the resistive fuel level sensor is in open circuit (disconnected).
A14 Fuel level low (digital sensor) Occurs if low fuel level is signalled by activation of the digital input programmed for this function.
A15 Battery voltage high Occurs if battery voltage remains above the threshold set in P05.02 for longer than the time set in P05.04.
A16 Battery voltage low Occurs if battery voltage remains below the threshold set in P05.03 for longer than the time set in P05.04.
A17 Battery discharged Occurs if engine start attempts have reduced battery voltage below the minimum threshold.
A18 Battery charging alternator fault Occurs if the engine is running (generator voltage and/or frequency or ‘W / pick-UP’ signal detected) but the battery
charging alternator signal (D+) remains under the engine running voltage threshold set in P11.01 for more than 4
seconds.
A19 “W / pick-up” signal fault Occurs if speed control is enabled and the engine is running (battery charging alternator signal or generator voltage
and/or frequency signal detected) but no ‘W / pick-up’ engine speed signal is detected within 5 seconds.
A20 “W / pick-up” low engine speed Occurs if the engine is running (battery charging alternator signal or generator voltage and/or frequency
signal
detected) and is not decelerated, but the ‘W / pick-up’ engine speed signal remains under the threshold set in
P07.05 for the time set in P07.06.
A21 “W / pick-up” high engine speed Occurs if the ‘W / pick-up’ engine speed signal remains over the
threshold set in P07.03 for the time set in P07.04.
A22 Start failure Occurs if the engine has not started after the set number of start attempts.
A23 Emergency stop Occurs if power is removed from the terminal +COM1 or if a digital input programmed to function as ‘Emergency
stop’ is activated.
A24 Unexpected engine stop Occurs after the alarm activation delay if the engine stops of its own accord, without the controller having
commanded the shut-down.
A25 Stop failure Occurs if the engine has not stopped 65 seconds after the beginning of the stop cycle.
A26 Generator frequency low Occurs if the engine is running but the frequency of the generator remains below the threshold set in P12.11 for the
time set in P12.12.
A27 Generator frequency high Occurs if the frequency of the generator remains above the threshold set in P12.09 for the time set in P12.10.
A28 Generator voltage low Occurs if the engine is running but the voltage of the generator remains below the threshold set in P12.01 for the
time set in P12.14.
A29 Generator voltage high Occurs if the voltage of the generator remains above the threshold set in P12.03 for the time set in P12.15.
A30 Generator voltage asymmetry Occurs if asymmetry between the generator phases exceeds the threshold set in P12.07 for the time set in P12.08.
A31 Generator maximum current Occurs if current from the generator exceeds the percentage threshold set in P13.01 for the time set in P13.02. If
this alarm occurs, wait for the reset time set in P13.05 before resetting it.
A32 Generator short circuit Occurs if current from the generator exceeds the percentage threshold set in P13.03 for the time set in P13.04.
A33 External generator protection tripped
If programmed, occurs if the digital input contact
for the generator's external thermal protection device closes while
the genset is running.
A34 Generator power threshold exceeded
Occurs if power from the generator exceeds the percentage threshold set in P17.03 for the time set in P17.04.
A35 Generator phase sequence wrong Occurs if the detected phase sequence does not correspond to that programmed.
A36 Generator switch fault Occurs after the time set in P17.05 if a discrepancy is detected between the state of the controller output and that of
the feedback input for the generator switch / breaker.
A37 Maintenance request Occurs when the hours of the maintenance interval reach zero. See menu M17. Use the Commands menu to reset
functioning hours and reset the alarm.
