ZAPI AC-1 Controller fault code

1. WATCH DOG

The test is made in both running and standby. It is a self-diagnosing test within the

logic. If an alarm should occur, replace the logic.

2. EEPROM KO

Fault in the area of memory in which the adjustment parameters are stored; this

alarm inhibits machine operation. If the defect persists when the key is switched OFF

and ON again, replace the logic. If the alarm disappears, remember that the param

eters stored previously have been cancelled and replaced by the default values.

3. LOGIC FAILURE #1

This alarm signals that an undervoltage / overvoltage protection operation has

occured. Two possible reasons:

1. A real undervoltage / overvoltage situation happened.
2. Fault in the hardware section of the logic board which manages the overvoltage

protection. Replace the logic card.

4. LOGIC FAILURE #2

Fault in the hardware section of the logic board which manages the phase’ s voltage

feedback. Replace the logic board.

5. LOGIC FAILURE #3

Fault in the hardware section of the logic board which manages the hardware current

protection. Replace the logic board.

6. CHECK UP NEEDED

This is a warning. It is an information for the user that the programmed time for main

tenance is elapsed.

7. INCORRECT START

This alarm signals an incorrect starting sequence. Possible causes:

1. running microswitch failure;
2. error in sequence made by the operator;
3. incorrect wiring;
4. if the default persists, replace the logic.
5. FORW + BACK

The test is carried out continuously. An alarm is signalled when a double running

request is made simultaneously. Possible causes:

1. defective wiring;
2. running microswitch failure;
3. incorrect operation;
4. if the defect persists, replace the logic.
5. HANDBRAKE

The truck does not start because the handbrake switch is opened. Possible causes:

defective wiring;

failure of the microswitch;

incorrect operation of the operator;

If the defect persist , replace the logic.
