HW
FAULT
MC
Cause:
At start-up, the hardware circuit dedicated to enable and disable the MC driver is
found to be faulty. The hexadecimal value
“
XX
”
facilitates
Zapi technicians debugging the problem
Troubleshooting:
This type of fault is not related to external components. Replace the logic board.
204
BRAKE
RUN
OUT
Cause:
The CPOT BRAKE input read by the microcontroller is at its maximum value
without the hand-brake request.
Troubleshooting:
Check the mechanical calibration and the functionality of the brake potentiometer.
If the alarm is still present, replace the logic board.
205
EPS
RELAY
OPEN
Cause:
The controller receives from EPS information about the safety contacts being open.
Troubleshooting:
Verify the EPS functionality.
206
INIT
VMN
HIGH
Cause
Before switching the LC on, the software checks the power-bridge voltage without
driving it. The software expects the voltage to be in a
“
steady state
”
value. If it is
too high, this alarm occurs.
Troubleshooting
- Check the motor power cables;
- Check the impedance between U, V and W terminals and -Batt terminal of the
controller.
- Check the motor leakage to truck frame.
- If the motor connections are OK and there are no external low impedance paths,
the problem is inside the controller. Replace it.
207
INIT
VMN
LOW
Cause
Before switching the LC on, the software checks the power-bridge voltage without
driving it. The software expects the voltage to be in a
“
steady state
”
value. If it is
too low, this alarm occurs.
Troubleshooting
- Check the motor power cables.
- Check the impedance between U, V and W terminals and -Batt terminal of the
controller.
- Check the motor leakage to truck frame.
- If the motor connections are OK and there are no external low impedance paths,
the problem is inside the controller. Replace it.
208
EEPROM
KO
Cause:
A HW or SW defect of the non-volatile embedded memory storing the controller
parameters. This alarm does not inhibit the machine operations, but it makes the
truck to work with the default values.
