CODE ALARM DESCRIPTION
22 VACC NOT OK Failure on the acceleration potentiometer signal at rest. The alarm points out
that the voltage value detected on the accelerator potentiometer is 1Volt
higher than the least value programmed with the Vacc function. Check:
- The traction potentiometer (it could be damaged or not correctly
calibrated)
- The traction potentiometer wiring.
- Carry out the Vacc setting again.
23 INCORRECT START replace the traction logic unit.
24 PEDAL WIRE KO Not used
25 WRONG BATTERY When the key is turned ON, the controller checks the battery voltage and
compares it with the “SET BATTERY” parameter setting. If the actual value
is 20% higher or lower than the nominal value, there is a fault. Replace the
battery with a correct one.
26 REMOTE IMPUT incorrect starting procedure.
28 STEER SENSOR KO This alarm signals that the steering potentiometer is out of range. There is a
fault in the following conditions:
- the “Set steer 0 pos” (straight wheels programmation) parameter is
wrong (lower than “Set steer min” or higher than “Set steer max”).
- the feedback signal of the steering potentiometer is outside the window
defined by the “Set steer min” and the “Set steer max” parameters.
In the first case, repeat the steering potentiometer acquisition. In the second
case, check the steering potentiometer and its wiring again. In case, repeat
once again the steering potentiometer acquisition .
29 FORW + BACK Incorrect sequce by starting. Check:
- Microswitch for forward/backward directions and relevant wires.
- Microswitch for parking brake and relevant wires.
1A SLAVE KO Failure on the slave module.
- Replace the traction unit.
1C BATTERY_LOW Discharged battery. If the “battery check” option is ON, a battery discharge
algorithm is carried out. When the charge level is 10% , this alarm is
ignalled and the current is reduced to the half of the programmed level.
2A CHOPPER The Dual AC2 traction unit has an erroneous configuration. Using the
NOT CONF. programming console it is possible to set the unit correctly according to the
truck configuration:
(0)double pedal version;
(1)manual inversor version;
(2)with inversor on the armrest.
(3)arm comand + direction selector on the steering column
1E CONTACTOR Failure on the contactor driver. Check the main contactors coils
CLOSED and the relevant wirings.
2C GAIN ACQUISITION This warning communicates that the logic is in phase of input acquisition. In
this phase the logic doesn't start.
2E HANDBRAKE Failure on parking brake. Check: the parking brake microswitch and the
relevant cables.
