capacitors:
- High voltage à Overvoltage condition
- Low/normal voltage à Undervoltage condition
Troubleshooting
If the alarm happens during the brake release, check the line contactor contact
and the battery power-cable connection.
203
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.
