ERROR CAUSE POSSIBLE REMEDY
Black The wheel balancer does not switch on. 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.
Err. 1 No rotation signal. 1. Check in self-diagnostics that the encoder functions properly.
2. Replace the phase pick-up board.
3. Replace the computer board.
Err. 2 Speed too low during detection.
During the unbalance measurement revolu-
tions, the wheel speed has fallen to below
42 rpm. 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.
Err. 3 Unbalance too high. 1. Verify wheel dimension settings.
2. Check detection unit connections.
3. Perform machine calibration.
4. Mount a wheel with more or less known unbalance (less than 100
grammes) and verify the response of the machine.
5. Replace the computer board.
Err. 4 Rotation in opposite direction.
After pressing [START], the wheel
starts turning in the opposite direction
(anticlockwise). 1. Check in self-diagnostics that the encoder functions properly
2. Check the bearing/spring of the phase generator
Err. 5 Guard open
The [START] pushbutton was pressed
without first closing the guard. 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.
Err. 6 Spindle open. The [START] button has
been pressed without first having closed the
spindle 1. Reset the error by pressing the button [7]=End
2. Close the spindle
3. Press the [START] button
Err. 7/
Err. 8/
Err. 10 NOVRAM parameter read error 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.
Err. 9 NOVRAM parameter write error. Replace the computer board.
Err. 11 Speed too high error.
During unbalance measurement rotation,
wheel speed is more than 270 rpm. 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.
Err.14/
Err.15/
Err.16/
Err.17/
Err.18/
Err.19 Unbalance measurement error. 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 unbalance (less than 100
grammes) and verify the response of the machine.
5. Replace the computer board.
