5) MOTOR TEMPERATURE
Cause:
This warning occurs when the temperature sensor is opened (if digital) or has
overtaken the threshold of 150° (if analogue).
Troubleshooting:
Check the thermal sensor inside the motor (use the MOTOR
TEMPERATURE reading in the TESTER menu); check the sensor ohmic
value and the sensor wiring. If the sensor is OK, improve the cooling of the
motor. If the warning is present when the motor is cool, then the problem is
inside the controller.
6) BRAKE RUN OUT
Cause:
The CPOTBRAKE input red by the microcontroller is at the maximum value
without the hand brake request.
Troubleshooting:
Check the mechanical calibration and the functionality of the brake
potentiometer. If the alarm is not disappeared the failure is in the ACE logic
board, replace it.
7) HAND BRAKE
Cause:
The hand brake input is active when a traction request is done.
Troubleshooting:
The possible reasons for this alarm are (use the readings in the TESTER to
facilitate the troubleshooting):
-
The HB switch is damaged so it does not close the input CNA#13 to –
Batt. Replace it.
- The HB switch work correctly but in the tester menu the HB input is
always ON. In this case the failure is in the logic board, replace it.
8) CURRENT GAIN
Cause:
The Maximum current gain parameters are at the default values, which
means the maximum current adjustment procedure has not been carried out
yet.
Troubleshooting:
Ask the assistance of a Zapi technician to do the correct adjustment
procedure of the current gain parameters
9) SENS MOT TEMP KO
Cause:
The output of the motor thermal sensor is out of range.
Troubleshooting:
Check the sensor ohmic value and the sensor wiring. If the sensor is OK,
then the problem is inside the ACE logic board, replace it.
10) THERMIC SENS KO
Cause:
The output of the controller thermal sensor is out of range.
Troubleshooting:
This type of fault is not related to external components; replace the controller.
