2) NO FULL COND.
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.
3) TH.PROTECTION
An indication that the chopper temperature has exceeded 79°C.
The maximum current is gradually reduced, reaching 0 at a temperature of 90°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.
4) BATTERY LOW
The battery charge is low.
The alarm is signalled only if the BATTERY CHECK option has been selected.
All functions except hydrodrive are inhibited.
5 ) INCORRECT START
A running request is present on key startup.
Possible causes:
a) Operator error.
b) Request microswitch stuck.
6) STBY I HIGH
Test carried out in standby, checks that the current is nil.
If this is not verified, an alarm is signalled. This alarm shuts down the machine. Possi-
ble causes:
a) Current sensor broken and logic failure.
First replace the logic, and if the defect persists, replace the power unit.
7) I=0 EVER
Test carried out in running.
Checks that the current during running is greater than a minimum value. If not, an alarm
is signalled and the machine is shut down. Possible causes:
a) The current sensor is faulty. Replace the power unit.
8) EEPROM PAR.KO
Fault in the area of memory in which the adjustment parameters are stored. This alarm
inhibits machine operation.
If the defect persists when the key is switched off and on again, replace the logic.
If the alarm disappears, remember that the parameters stored previously have been
cancelled, and replaced by the default values.
