CAUTION
Err. 20 The wheel comes to a halt before comple-
ting positioning correctly.
1. Make sure that the wheel to be balanced is at least 10” in diame-
ter.
2. Verify the correct setting of wheel dimensions on screen.
3. Verify belt tautness.
4. For wheels less than 12” in diameter wheels: disenable the
eccentricity measurement procedure
Err. 30 Clock error 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
plotting 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 card.
4. Replace the eccentricity measurement sonar.
5. Make sure that the wheel does not halt before completing at least
4/5 revolutions after the first braking impulse.
6. Verify belt tautness.
7. Replace the computer board.
Err.55 Sonar readout error.
Sonar values are insufficient 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 first 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
number of values necessary for reliable eccentricity measurement.
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.
