STOP analog, see paragraph 7.2.3).
Troubleshooting:
- Check the temperature read by the thermal sensor inside the motor through the
MOTOR TEMPERATURE reading in the TESTER function.
- 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, replace the controller.
179
STEER
SENSOR
KO
Cause:
The voltage read by the microcontroller at the steering-sensor input is not within
the STEER RIGHT VOLT
÷
STEER LEFT VOLT range, programmed
through the STEER ACQUIRING function
Troubleshooting:
- Acquire the maximum and minimum values coming from the steering
potentiometer through the STEER ACQUIRING function. If the alarm is
still present, check the mechanical calibration and the functionality of the
potentiometer.
- If the problem is not solved, replace the logic board
180
OVERLO
AD
Cause
The motor current has overcome the limit fixed by hardware.
Troubleshooting
Reset the alarm by switching key off and on again. If the alarm condition occurs
again, ask for assistance to a Zapi technician. The fault condition could be affected
by wrong adjustments of motor parameters.
181
WRONG
ENC SET
Cause
Mismatch between
“
ENCODER PULSES 1
”
parameter and
“
ENCODER
PULSES 2
”
parameter (see paragraph 7.2.5).
Troubleshooting
Set the two parameters with the same value, according to the adopted encoder.
182
EVP2
COIL
OPEN
Cause:
No load is connected between the EVP2 output and the electrovalve positive
terminal
Troubleshooting:
- Check the EVP2 condition.
- Check the EVP2 wiring
- If the problem is not solved, replace the logic board.
183
EVP2
DRIV.
SHORT
Cause
- The EVP2 driver is shorted.
- The microcontroller detects a mismatch between the valve set-point and the
feedback of the EVP2 output
