Diagnostics
Err. 22 Maximum number of spins possible for
the unbalance measurement has been
exceeded. 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.
Err.40/
Err.41/
Err.42/
Err.43 Eccentricity graph plotting procedure error. Perform a new eccentricity measurement.
Err.45/
Err.46/
Err.47/
Err.48 Eccentricity graph value display readout
error. Perform a new eccentricity measurement.
Err.50/
Err.51/
Err.52/
Err.53 Eccentricity graph current value cursor plot-
ting procedure error. Perform a new eccentricity measurement.
Err.54 Sonar readout error.
Sonar value readout impossible. 1. Position the eccentricity measurement sonar correctly before
performing the measurement.
2. Check eccentricity sonar connections.
3. Check the power supplies on the power board.
4. Replace the eccentricity measurement sonar.
5. Make sure that the wheel does not halt before completing at least
4/5 revolutions after the fi rst braking impulse.
6. Replace the computer board.
Err.55 Sonar readout error.
Sonar values are insuffi cient for correct
measurement of eccentricity. 1. Position the eccentricity measurement sonar correctly before
performing the measurement.
2. Make sure that the wheel does not halt before completing at least
4/5 revolutions after the fi rst braking impulse.
3. Mount a wheel of medium dimensions (14”x5 ¾”) and perform an
eccentricity measurement . If in these conditions error 55 no longer
occurs, this means that the wheel inertia causing the problem is
such as to half the wheel before having acquired the minimum
number of values necessary for reliable eccentricity measurement.
Unbalance
incorrect
with back
centring
cones Wheel slipping on the adapter because the
BP system is at the end of travel or because
of incorrect fi tting of the tyre tie-rod Mount the wheel in vertical position and push the sleeve up
against the wheel. If necessary, repeat locking/unlocking/locking
and perform the procedure again.
