ERROR ERROR TEXT POSSIBLE CAUSE FAULT CLEARANCE
1 WRONG CONFIG This alarm occurs the first time a control-
ler is switched on when the non volatile
eeprom memory is not initialized yet.
Then it is necessary to specify if the
controller is AC-0 or AC-1 type (see
AC TYPE 0 in the hidden hardware
setting Zapi menu). If the alarm is pres-
ent, by switching off the key the AC
TYPE 0 setting will be automatically
turned On (and the controller is speci-
fied to be an AC-0). The AC TYPE 0
setting can be changed only when a
WRONG CONFIG alarm is present. If it
is not present, it is necessary to clear
the eeprom memory if the WRONG
CONFIG alarm occurs.
The AC TYPE 0 setting must be factory
adjusted and so the alarm should
never happen. So ask for the assis-
tance of a Big Lift LLC Service Repre-
sentative when this alarm occurs.
8 WATCH DOG This alarm occurs when the embedded
WATCH DOG protection is not able to
either cut off the power stage when not
triggered or it is not able to activate the
power stage when triggered.
Verify the motor is connected and there
is continuity of the three motor phases.
If the alarm occurs permanently,
replace the controller.
16 AUX OUPUT KO This alarm occurs when the feedforward
PWM generated by the controller to
supply the Electromechanical Brake
are not matched in between. The diag-
nosis is made only when the Tiller
Switch is active.
Replace the controller because the
driver of the Electromechanical Brake
has a failure.
13 EEPROM KO This alarm occurs due to a HW or SW
defect of the non-volatile embedded
memory supporting the controller regu-
lations.
Try to execute a CLEAR EEPROM oper-
ation. This consists of entering
ALARMS in the MAIN MENU. Push at
the same time the two right side but-
tons to enter the hidden ZAPI MENU.
Roll up and down until the CLEAR
EEPROM appears on the handset dis-
play. Push the Enter Button two times.
Switch the key off and on to check the
result. If the alarm occurs permanently,
replace the controller.
17 LOGIC FAILURE #3 This alarm occurs when the circuit to
limit via HW the current peak in the
controller is active.
If is probably a power failure or a logic
failure. If the alarm occurs perma-
nently, replace the controller.
18 LOGIC FAILURE #2 This alarm occurs when the circuit, to
compensate for the dead times of the
sine waves, is failed.
Replace the Controller.
