ERROR CAUSE REMEDY
Err.54 Sonar readout error.
Sonar value readout impossible.
1. Position the eccentricity measurement sonar correctly before per-
forming 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. Verify belt tautness.
7. Replace the computer board.
Err.55 Sonar readout error.
Sonar values are insuffi cient for cor-
rect measurement of eccentricity.
1. Position the eccentricity measurement sonar correctly before per-
forming 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. Verify belt tautness.
4. 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 num-
ber of values necessary for reliable eccentricity measurement.
Err.56 Lateral Sonar readout error.
Lateral Sonar value readout impos-
sible.
1. Position the eccentricity measurement lateral sonar correctly before
performing the measurement.
2. Check eccentricity lateral sonar connections.
3. Check the power supplies on the power board.
4. Replace the eccentricity lateral sonar.
5. Make sure that the wheel does not stop before completing at least
4/5 revolutions after the fi rst braking impulse.
6. Verify belt tautness.
7. Replace the computer board.
Err.57 Lateral Sonar readout error.
Lateral Sonar values are insuffi cient
for correct measurement of lateral
eccentricity.
1. Position the eccentricity lateral sonar correctly before performing the
measurement.
2. Make sure that the wheel does not stop before completing at least
4/5 revolutions after the fi rst braking impulse.
3. Verify belt tautness.
4. Mount a wheel of medium dimensions (14”x5 ¾”) and perform an
eccentricity measurement. If in these conditions error 57 no longer
occurs, this means that the wheel inertia causing the problem is
such as to half the wheel before having acquired the minimum num-
ber of values necessary for reliable lateral eccentricity measurement.
Err.58 Radial and lateral Sonar readout error.
Radial and lateral Sonar value readout
impossible.
1. Check points Err. 54
2. Check points Err. 56
Err.59 Radial and lateral Sonar readout error.
Lateral and radial Sonar values are
insufficient for correct measurement
of radial and lateral eccentricity.
1. Check points Err. 55
2. Check points Err. 57
Err.65 Printer timeout 1. Check that a printer is present.
2. Check the code of the processor card.
3. Check the printer <-> processor card connection.
4. Run the printer test function.
Err.66 Printer buffer error 1. Reset the printer.
2. Repeat the print function.
Err.70 Error regarding ADC 16 bit readings 1. Check correct connection cable for distance and diameter gauge
(CN5/CN4).
2. Switch off the machine, wait about 30 seconds and switch on again .
3. Replace the PC board.
Out of
balance
incorrect
with back
centering
cone Wheel slipping on the adapter be-
cause the BP system is at the end of
travel or because of incorrect fitting
of the tire 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.
