A04 Pressure switch alarm
This alarm occurs when either the high or low pressure switch trips. The high
pressure switch may trip due to poor cleaning of the condenser or loosened con-
denser fan belts.
The low pressure switch may trip due to refrigerant leaks. By tripping it causes
the machine to stop until the alarm itself disappears.
A05 Low battery level alarm
This alarm occurs if battery power is lower than 11.5V. It turns the machine off
until power remains above 11.5V for at least 1'. Warning: making the engine work
for short periods (with frequent peaks) causes the battery to exhaust.
A06 Cargo area sensor failure alarm
This alarm causes the machine to permanently stop until the problem has been
solved. To start the machine again, it must be reset using the procedure
described in the paragraph above and the
ON/OFF key must be pressed.
A07 Defrost sensor failure alarm
It is a warning alarm which has no consequences on the operation of the
machine.
A08 Starting failure/damaged alternator
This alarm may occur if the diesel engine did not start after the maximum num-
ber of startup attempts (factory-set at 5).
Possible causes include: broken alternator, loose belts, no fuel. If the same alarm
occurs during electric standby, it should be attributed to a broken alternator.
To start the machine again, you need to reset the alarm by following the proce-
dure described in the above section and press the ON/OFF key
.
A09 High/low temperature alarm
This alarm occurs if the differential between actual temperature of the cold room
and the temperature value set using the control exceeds a factory-set limit. It is
a warning alarm which has no consequences on the operation of the machine.
A10 Radiator water level alarm (optional)
