Troubleshooting:
It is necessary to improve the controller cooling. To realize an adequate
cooling in case of finned heat sink important factors are the air flux and the
cooling-air temperature. If the thermal dissipation is realized by applying the
controller base plate onto the truck frame, the important factors are the
thickness of the frame and the planarity and roughness of its surface.
If the alarm occurs when the controller is cold, the possible reasons are a
thermal-sensor failure or a failure in the logic board. In the last case, it is
necessary to replace the controller.
THERMIC SENS. KO
(MDI/LED code = 61)
Cause:
The output of the controller thermal sensor is out of range.
Troubleshooting:
This kind of fault is not related to external components. Replace the
controller.
THROTTLE PROG.
(MDI/LED code = 48)
Cause:
A wrong profile has been set in the throttle profile.
Troubleshooting:
Set properly the throttle-related parameters (see paragraph 9.8).
TILLER ERROR
(MDI/LED code = 64)
Cause:
Input mismatch between the Hard&Soft input (
A6 ) and the TILLER/SEAT input
( A1 ): the two inputs are activated at the same time.
Troubleshooting:
- Check if there are wrong connections in the external wiring.
- Using the TESTER menu of the controller verify that what the controller
sees in input is in accordance with the actual state of the external switch
inputs.
- Check if there is a short circuit between A6 and A1 .
- In case no failures/problems have been found, the problem is in the
controller, which has to be replaced.
TILLER OPEN
(MDI/LED code = 51)
Cause:
Tiller/seat input has been inactive for more than 120 seconds.
Troubleshooting:
-
Activate the tiller/seat input.
- Check the tiller/seat input state through the TESTER function.
- Check the wirings.
- Check if there are failures in the microswitches.
- If the problem is not solved, replace the logic board.
TORQUE PROFILE
(MDI/LED code = 98)
Cause:
There is an error in the choice of the torque profile parameters.
