MOTOR
TEMP. STOP
The temperature sensor has
overtaken the threshold defined
by STOP MOTOR TEMP.
1- Check the temperature read by the
thermal sensor inside the motor
through the MOTOR TEMPERATURE
reading in the TESTER function.
2- Check the sensor ohmic value and the
sensor wiring.
3- If the sensor is OK, improve the
cooling of the motor.
4- If the warning is present when the
motor is cool, replace the controller.
179
STEER
SENSOR KO
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
1- 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.
2- If the problem is not solved, replace
the logic board.
180 OVERLOAD
The motor current has overcome
the limit fixed by hardware.
If the alarm condition occurs again, ask
for assistance to a EP technician.
The fault condition could be affected by
wrong adjustments of motor parameters.
181
WRONG ENC
SET
Mismatch between parameters
ENCODER PULSES 1 and
ENCODER PULSES 2
Set the two parameters with the same
value, according to the adopted encoder
182
EVP2 COIL
OPEN
No load is connected between
the EVP2 output and the
electrovalve positive terminal.
1- Check the EVP2 condition.
2- Check the EVP2 wiring.
3- If the problem is not solved, replace
the logic board.
