AC-0 Controller fault code

1) WATCH DOG

MDI-PRC Code = 8

– Cause: It occurs when the embedded WATCH DOG protection is not

able either to cut off the power stage when not triggerd or it is

not able to activate the power stage when triggered.

– Remedy: Verify the motor is connected and the continuity of the three

motor phases. If the alarm occurs permanently, it is necessary

to substituite the controller.

2) EEPROM KO

MDI-PRC Code = 13

– Cause: It occurs due to a HW or SW defect of the non-volatile

embedded memory supporting the controller regulations.

– Remedy: Try to execute a CLEAR EEPROM operation. This consists of

Entering the ALARMS item in the MAIN MENU’. Push at the

same time the two right side buttons to enter the hidden ZAPI

MENU’. Roll up and Down until the CLEAR EEPROM appears

on the hand set display. Push Twice the Enter Button. Switch

the key off and on to check the result. If the alarm occurs

permanently, it is necessary to substituite the controller.

3) LOGIC FAILURE #1

MDI-PRC Code = 19

– Cause: It occurs when the battery voltage overtakes 45V (when the

battery is 24V) or 47.5V (when the battery is 36V). It also

occurs when the supply voltage inside the logic falls less than11Vdc.

– Remedy: Normally the overvoltage occurs due to the regenerative

braking energy increasing the battery voltage; the undervoltage

of the logic supply, can be due to a depletion in the key voltage

So first of all check for your failure mode then contact the Zapi

technician to look for a countermeasure.

As a matter of fact this alarm may occurs also for a HW failure

and, in this case, it is necessary to substituite the Controller.

4) LOGIC FAILURE #2

MDI-PRC Code = 18

– Cause: It occurs when the circuit, to compensate for the dead times of

the sine waves, is failed.

– Remedy: It is necessary to substituite the Controller.

5) LOGIC FAILURE #3

MDI-PRC Code = 17

– Cause: It occurs when the circuit to limitate via HW the current peak in the controller is active.

– Remedy: It is probably a power failure or a logic failure. If it occurs

permanently it is necessary to substituite the Controller.

6) CHECK UP NEEDED

MDI-PRC Code = 99

– Cause: This is just a warning to call for the time programmed maintanance.

– Remedy: It is just enough to turn the CHECK UP DONE option to level

ON ，after the maintanance is executed.
