Troubleshooting:
- Check if there is a short or a low impedance path between the negative coil
terminal and -BATT.
- Check if the voltage applied is in accordance with the parameters set .
- If the problem is not solved, replace the controller.

WATCHD
OG
Cause:
This is a safety related test. It is a self-diagnosis test that involves the logic between
master and supervisor microcontrollers
Troubleshooting:
This alarm could be caused by a CAN bus malfunctioning, which blinds
master-supervisor communication
17
LOGIC
FAILURE
#3
Cause
An hardware problem in the logic board due to high currents (overload). An
overcurrent condition is triggered even if the power bridge is not driven.
Troubleshooting
The failure lies in the controller hardware. Replace the controller.
19
LOGIC
FAILURE
#1
Cause:
This fault is displayed when the controller detects an undervoltage condition at the
key input .
Undervoltage threshold is 11V for 36/48V controllers and 30 V for 80V controllers.
- Fault can be caused by a key input signal characterized by pulses below the
undervoltage threshold, possibly due to external loads like DC/DC converters
starting-up, relays or contactors during switching periods, solenoids energizing or
de-energizing. Consider to remove such loads.
- If no voltage transient is detected on the supply line and the alarm is present
every time the key switches on, the failure probably lies in the controller hardware.
Replace the logic board.
Troubleshooting (fault displayed during motor driving)
- If the alarm occurs during motor acceleration or when there is a
hydraulic-related request, check the battery charge, the battery health and
power-cable connections.
199
BUMPER
STOP
Cause
The two digital inputs dedicated to the bumper functionality are high at the same
time.
Troubleshooting
- Turn off one or both inputs dedicated to the bumper functionality;
- If the alarm occurs even if the inputs are in the rest position, check if the
microswitches are stuck.
- In case the problem is not solved, replace the logic board.
