- Motor connections
- If motor windings/cables have leakages towards truck frame
- That the LC power contact closer properly, with a good contact
- If no problem are found on the motors, the problem is inside the
controller.
27) “PUMP VMN HIGH”
Cause:
This test is carried out when the pump motor is turning (pwm applied). The
pump motor output is higher than expected, considering the pwm applied.
Troubleshooting:
It is suggested to check:
A) Motor connections
B) If motor windings/cables have leakages towards truck frame
C) If no problem are found on the motors, the problem is inside the
controller
28) “WRONG ZERO”
Cause:
The outputs of the amplifiers (used to measure the traction motor voltage)
are checked to be included into a range . This alarm occurs when the voltage
signals >3V or <2V at the init.
Troubleshooting:
This type of fault is not related to external components; replace the controller.
29) ”EVP1 COIL OPEN”
Cause:
This fault appears when the LOWER EVP1 output is used (parameter “EVP
TYPE” in “SET OPTION” menu is set ANALOG or DIGITAL) but no load is
connected between the output and PAUX positive.
Troubleshooting:
A) It is suggested to check the harness, in order to verify if EVP1 coil is
connected to the right connector pin and if it is not interrupted.
B) If, even connecting the coil to the right pin or replacing it, the alarm is still
present than the problem is inside the controller logic board, replace it.
30) ”EVP2 COIL OPEN”
Cause:
This fault appears when the EVP2 output is used (parameter “EVP2 TYPE” in
“SET OPTION” menu is set ANALOG or DIGITAL) but no load is connected
between the output and PAUX positive.
Troubleshooting:
A) It is suggested to check the harness, in order to verify if EVP2 coil is
connected to the right connector pin and if it is not interrupted.
B) If, even connecting the coil to the right pin or replacing it, the alarm is still
present than the problem is inside the controller logic board, replace it.
31) “AUX BATT. SHORT”
Cause:
A) The coil on the aux output is not correctly connected.
B) The smartdriver inside the controller is damaged.
Troubleshooting:
- It is suggested to check that the coil is correctly connected between A2
and A4.
- If no problem is found on the coil, the problem is inside the controller.
