procedure.
Troubleshooting:
- Check the wirings.
- Check the mechanical calibration and the functionality of the accelerator
potentiometer.
- Acquire the maximum and minimum potentiometer value through the
PROGRAM VACC function.
- If the problem is not solved, replace the logic board.

INCORR
ECT
START
Cause:
Incorrect starting sequence. Possible reasons for this alarm are:
- A travel demand active at key-on.
- Man-presence sensor active at key on.
Troubleshooting:
- Check wirings.
- Check microswitches for failures.
- Through the TESTER function, check the state of the inputs are coherent with
microswitches states.
- If the problem is not solved, replace the logic board.
80
FORW +
BACK
Cause:
This alarm occurs when both the travel requests (FW and BW) are active at the
same time.
Troubleshooting:
- Check that travel requests are not active at the same time.
- Check the FW and BW input states through the TESTER function.
- Check the wirings relative to the FW and BW inputs.
- Check if there are failures in the microswitches.
- If the problem is not solved, replace the logic board.

ENCODE
R ERROR
Cause
This fault occurs in the following conditions: the frequency supplied to the motor is
higher than 40 Hz and the signal feedback from the encoder has a jump higher than
40 Hz in few tens of milliseconds. This condition is related to an encoder failure.
Troubleshooting
- Check the electrical and the mechanical functionality of the encoder and the
wires crimping.
- Check the mechanical installation of the encoder, if the encoder slips inside its
housing it will raise this alarm.
- Also the electromagnetic noise on the sensor can be the cause for the alarm. In
these cases try to replace the encoder.
- If the problem is still present after replacing the encoder, the failure is in the
controller.

WIRE KO
This is not implemented in ACE3.
Troubleshooting:
- Ask for help to a Zapi technician.
