- Verify the CANbus network (external issue).
- Replace the logic board (internal issue).
OFFSET SPD.SENS.
(MDI/LED code = 3)
Cause:
It is necessary to acquire the offset angle between the stator and the speed
sensor, i.e. they mutual angular misalignment. An automatic function is
dedicated to this procedure.
Troubleshooting:
Perform the teaching procedure: in OPTIONS, select ABS SENS. ACQUIRE.
See paragraph 7.3.1 for more details.
OPEN COIL EV.
(MDI/LED code = 21)
Cause:
This fault appears when no load is connected between one or more EV
outputs and the positive terminal PEV (pin
A3 ). For the meaning of code
“XX”, refer to paragraph 10.510.5.
Troubleshooting:
- Check the coils.
- Check the wiring.
- If the problem is not solved, replace the logic board.
OVERLOAD
(MDI/LED code = 57)
Cause
The motor current has overcome the limit fixed by hardware.
Troubleshooting
If the alarm condition occurs again, ask for assistance to a Zapi technician.
The fault condition could be affected by wrong adjustments of motor
parameters.
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 does cancel the alarm.
- If the alarm appears at key-on without any CLEAR EEPROM performed,
replace the controller.
PARAM TRANSFER
(MDI/LED code = 93)
Cause:
Master uC is transferring parameters to the supervisor.
Troubleshooting:
Wait until the end of the procedure. If the alarm remains longer, re-cycle the
key.
