5 ALARMS
"ZAPI CONSOLE" "MDI"
1) POWER FAILURE #1 73
Short-circuit on the ON/OFF valves, or in the main contactor coil, or in the
electrobrake coil.
2) EEPROM KO 13
Fault in the area of memory where the parameters are stored. This alarm inhibits
machine operation. If the fault continues when the Key switch is turned off and on
again, replace the logic. If the fault disappears, the previously stored parameters
will be replaced by the default parameters.
3) INCORRECT START 79 (Traction), 95 (Pump)
Alarm generated by an incorrect starting sequence. Possible reasons:
a) The Enable microswitch has welded or failed.
b) Error in the starting sequence from the operator.
c) Error in the wiring.
d) Lifting operation awaiting when the key is turned on.
4) CAPACITOR CHARGE 60
This check is made during the initial diagnosis. This Alarm is generated if the
capacitors are not charged within 500 mSec after the Key switch on. Probable
cause is a failure within the power block.
5) VMN NOT OK 32
This test is performed at rest, with the Main Contactor closed, and also during
operation. This Alarm is generated if the VMN is lower than battery voltage in stand-
by. This alarm is generated if VMN does not follow the duty-cycle of the chopper
while driving. Possible causes:
a) Incorrect motor connection.
b) Frame fault of motor to chassis.
c) Defect in the power unit.
6) VACC NOT OK 78
This Alarm is generated if the accelerator output voltage from the serial tiller is
higher than 1V. Possible causes to be checked on the serial tiller:
a) the track of the potentiometer has become open.
b) the potentiometer is not wired correctly.
c) the potentiometer itself is defective.
d) the values set during the acquisition procedure are wrong.
