OUT MISMATCH PU (MDI/LED code = 20)
Cause:
This is a safety related test. Supervisor C has detected that master C is
driving the pump motor in a wrong way (not corresponding to the operator
request).
Troubleshooting:
- Checks the matching of the parameters between Master and Supervisor.
- Ask for assistance to a Zapi technician.
- If the problem is not solved, replace the logic board.
PARAM RESTORE (MDI/LED code = 14)
Cause:
The controller has restored the default settings. If a CLEAR EEPROM has
been made before the last key re-cycle, this warning informs you that
EEPROM was correctly cleared.
Troubleshooting
:
- A travel demand or a pump request cancels the alarm.
- If the alarm appears at key-on without any CLEAR EEPROM performed,
replace the controller.
SP MISMATCH XX (MDI/LED code = 15)
Cause:
This is a safety related test. The supervisor C has detected a mismatch in
the speed setpoint with respect to the master C. The hexadecimal value
“XX” facilitates Zapi technicians debugging the problem.
Troubleshooting:
- Check the matching of the parameters between master and supervisor.
- Ask for assistance to a Zapi technician.
- If the problem is not solved, replace the logic board.
SP MISMATCH PUMP (MDI/LED code = 18)
Cause:
This is a safety related test. The supervisor C has detected a mismatch in
the DC-pump speed setpoint with respect to the master C.
Troubleshooting:
- Check the matching of the parameters between master and supervisor.
- Ask for assistance to a Zapi technician.
- If the problem is not solved, replace the logic board.
STEER SENSOR KO (MDI/LED code = 95)
Cause:
The voltage read by the microcontroller at the steering-sensor input is not
within the range from STEER RIGHT VOLT to STEER LEFT VOLT,
programmed through the STEER ACQUIRING function (see paragraph 9.3).
Troubleshooting:
- Acquire the maximum and minimum values from the steering
potentiometer through the STEER ACQUIRING function.
- Check the mechanical calibration and the functionality of the
potentiometer.
- If the problem is not solved, replace the logic board.
