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.

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)

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.
