12.0 DIAGNOSTICS
WARNING
The information in the POSSIBLE REMEDY column requires work to be performed by
specialist technicians or other authorised people who must always work using the
Personal Protective Equipment indicated in the INSTALLATION manual. In some cases,
this work can be performed by a normal operator.
ERROR
CAUSE
Black
The wheel balancer does not switch on.
Err. 1
No rotation signal.
Speed too low during detection.
During the imbalance measurement
Err. 2
revolutions, the wheel speed has fallen
to below 42 rpm.

POSSIBLE REMEDY
1.
Verify correct connection to the mains.
2.
Verify and eventually replace the fuses on the power card.
3.
Verify monitor function.
4.
Replace the computer board.
1.
Check in self-diagnostics that the encoder functions properly.
2.
Replace the phase pick-up board.
3.
Replace the computer board.
1. Make sure that a vehicle wheel is mounted on the wheel balancer.
2. Use the self-diagnostics function to check the encoder.
3. Disconnect the piezo connectors from the board and do a spin
(if no error is detected, replace the piezo sensors).
4. Replace the CPU board.
1.
Verify wheel dimension settings.
2.
Check detection unit connections.
3.
Perform machine calibration.
4.
Mount a wheel with more or less known imbalance (less than 100
grammes) and verify the response of the machine.
5.
Replace the computer board.
1.
Check in self-diagnostics that the encoder functions properly
2.
Check the bearing/spring of the phase generator
1.
Reset the error by pressing pushbutton [7]=End.
2.
Close the guard.
3.
Verify the function of the protection uSwitch.
4.
Press the [START] pushbutton.
1.
Repeat machine calibration
2.
Shut down the machine.
3.
Wait for a minimum time of ~ 1 Min.
4.
Re-start the machine and verify correct operation.
5.
Replace the computer board.
Replace the computer board.
1.
Check if there is any damage or dirt on the timing disc.
2.
Check in self-diagnostics that the encoder functions properly.
3.
Replace the computer board.
1.
Check in self-diagnostics that the encoder functions properly
2.
Check detection unit connections.
3.
Verify machine earth/ground connection.
4.
Mount a wheel with more or less known imbalance (less than 100
grammes) and verify the response of the machine.
5.
Replace the computer board.
1. Check that a vehicle wheel has been mounted on the wheel
balancer.
2. Check in self-diagnostics that the encoder functions properly
3. Replace the computer board.
Replace the computer board.
Perform a new eccentricity measurement.
