ERRORS CAUSE POSSIBLE REMEDY
Black
The wheel balancer does not switch on. 1. Check proper connection to the mains.
2. Check and if necessary replace the fuses on the power board.
3. Verify monitor function.
4. Replace the CPU board
Err. 1 No rotation signal. 1. Check functioning of the phase generator and, in particular, the
reset signal.
2. Replace the phase generator.
3. Replace the CPU board.
Err. 2 Speed too low during detection.
During the unbalance measurement
revolutions, the wheel speed has fallen
to below 42 rpm.
1. Make sure that a vehicle wheel is mounted on the wheel balancer.
2. Check functioning of the phase generator and, in particular, the
reset signal.
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. Check the wheel dimension setting.
2. Check detection unit connections.
3. Perform machine calibration.
4. Mount a wheel with more or less known unbalance (less than 100
grams) and verify the response of the machine.
5. Replace the CPU board.
Err. 4 Rotation in opposite direction. After
pressing [START], the wheel begins to
rotate in the opposite direction (ant
clockwise).
1. Check in self-diagnostics that the encoder functions properly
2. Check the bearing/spring of the encoder
Err. 5
Guard open.The [START] push butto
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 Switch.
4. Press the [START] button.
Err. 7 /
Err. 8
NOVRAM parameter read error 1. Repeat machine calibration
2. Shut down the machine.
3. Wait for at least ~ 1 min.
4. Re-start the machine and verify correct operation.
5. Replace the CPU board.
Err. 9 NOVRAM parameter write error Replace the CPU board.
Err. 11 Speed too high error.During unbalance
measurement rotation, wheel speed is
more than 100 rpm.
1. Check in self-diagnostics that the encoder functions properly.
2. Replace the computer board.
Err. 12
Unbalance measuring cycle error. 1. Check functioning of the phase generator.
2. Verify correct motor operation.
3. Replace the CPU board.
