Description of the alarms signalled by the diagnostic LED.
The alarm code is shown in parentheses. A detailed description is given in the section
“DECODING THE ALARMS DISPLAYED ON CONSOLE”.

The test is carried out in standby. If the VMN voltage is lower than 1/3 of the battery
voltage, an alarm is signalled. Possible causes:
a) Check the motor wiring to make sure it is correct.
b) Chopper broken, replace.

The test is carried out in full conduction.
If, in this condition, the VMN is found to be greater than 1/3 VBATT, the diagnostic
circuit is faulty, causing a safety risk, and thus machine operation is inhibited. If the defect
persists, replace the logic.

TH.PROTECTION
An indication that the chopper temperature has exceeded 80°C.
The maximum current is gradually reduced, reaching 0 at a temperature of 85°C. If the
alarm occurs while cold:
a) Check the thermal sensor connection.
b) Thermal sensor failure.
c) Connection on the power interrupted (check the connector that connects the logic to
the power unit).
d) Logic failure.

The battery charge is low.
The alarm is signalled only if the BATTERY CHECK option has been selected. All
functions except hydrdrive are inhibited.
