CAUSE
With the motor stopped for more than one minute, the
oil sensor is not closed to signal lack of pressure. It is
therefore assumed that the connection is interrupted.
Fuel level below the pre-alarm threshold set with P11.08.
Fuel level below the alarm threshold set with P11.09.
Is activated when the threshold set with P11.12 is ex-
ceeded and is used to activate the siren.
Is activated when the threshold set with P11.13 is ex-
ceeded and is used to activate the siren.
The resistive fuel level sensor is an open circuit (discon-
nected).
Low fuel level indicated by activation of the digital input
programmed with the appropriate function.
Alarm generated when the liquid level of cooling is below
the minimum level. Activated by digital input.
With speed measurement enabled, the alarm occurs
when the D+ signal is detected (presence of battery
charger alternator signal) but the speed signal 'W/pick-
up' is not detected within 5 seconds.
With speed measurement enabled, the alarm occurs
when the 'W/pick-up' sensor is disconnected even with
the motor stopped.
It occurs when the motor is running (presence of battery
charger alternator signal), not decelerated, and the speed
signal 'W/pick-up' remains below the threshold of P07.05
for the time set in P07.06.
This occurs when the speed signal 'W/pick-up' remains
above the threshold of P07.03 for the time set in P07.04.
Alarm generated when the analogue input of the pinion
signals that the motor start is on but has not been re-
quested.
Alarm generated when the analogue input of the pinion
signals that it is not engaged and the motor start has not
been requested.
Alarm generated when the pinion analogue input is not
correctly connected.
Alarm generated when the contact signals the presence
of water in the fuel. Activated by digital input.
Occurs when, after having made the number of attempts
to start the motor, the motor still has not started.
This alarm occurs when the motor stops autonomously,
after the time when the alarms have been activated,
without the appliance having intentionally caused it to
shut down.
Alarm generated if the motor has not yet stopped
65 seconds after the start of the stop phase.
Battery voltage higher than the set threshold with for a
time longer than P05.04.
Battery voltage lower than the threshold set with P05.03
for a time longer than P05.04.
Maximum number of attempts to start from battery A
exhausted. Battery voltage lowered below the minimum
supply threshold.
Alarm generated by the input programmed with the
function - Battery Charger Alarm A - connected to an ex-
ternal battery charger when the mains voltage is within
the limits.
