DESCRIPTION
CAUSE
A15
Fault digital oil pressure sensor
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.
A16
Low fuel prewarning (analogue sensor)
Fuel level below the pre-alarm threshold set with P11.08.
A17
Low fuel level (analogue sensor)
Fuel level below the alarm threshold set with P11.09.
A18
High fuel level pre-alarm (analogue sensor)
Is activated when the threshold set with P11.12 is ex-
ceeded and is used to activate the siren.
A19
High fuel level (analogue sensor)
Is activated when the threshold set with P11.13 is ex-
ceeded and is used to activate the siren.
A20
Analogue level sensor failure
The resistive fuel level sensor is an open circuit (discon-
nected).
A21
Low fuel level (digital sensor)
Low fuel level indicated by activation of the digital input
programmed with the appropriate function.
A22
Low radiator liquid level
Alarm generated when the liquid level of cooling is below
the minimum level. Activated by digital input.
A23
Signal failure "W/pick-up"
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.
A24
"W/pick-up" disconnected
With speed measurement enabled, the alarm occurs
when the 'W/pick-up' sensor is disconnected even with
the motor stopped.
A25
Low speed "W/pick-up" motor
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.
A26
Low fuel prewarning (analogue sensor)
This occurs when the speed signal 'W/pick-up' remains
above the threshold of P07.03 for the time set in P07.04.
A27
Pinion inserted (feedback on during pause)
Alarm generated when the analogue input of the pinion
signals that the motor start is on but has not been re-
quested.
A28
Pinion not engaged (feedback off during cranking)
Alarm generated when the analogue input of the pinion
signals that it is not engaged and the motor start has not
been requested.
A29
Pinion sensor disconnected
Alarm generated when the pinion analogue input is not
correctly connected.
A30
Water in fuel
Alarm generated when the contact signals the presence
of water in the fuel. Activated by digital input.
A31
Failure to start
Occurs when, after having made the number of attempts
to start the motor, the motor still has not started.
A32
Unexpected stop
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.
A33
Failure to stop
Alarm generated if the motor has not yet stopped
65 seconds after the start of the stop phase.
A34
Battery voltage A high
Battery voltage higher than the set threshold with for a
time longer than P05.04.
A35
Battery voltage A low
Battery voltage lower than the threshold set with P05.03
for a time longer than P05.04.
A36
Inefficient A battery
Maximum number of attempts to start from battery A
exhausted. Battery voltage lowered below the minimum
supply threshold.
A37
Battery charger alarm A
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.
