Symptom
Error in the Sonar reading.
The values taken by the Sonar
are insufficient for a correct
runout measurement.
Error in Lateral Sonar reading.
Sonar did not read any value.
Error int the Lateral Sonar read-
ing. The values taken by the
Sonar are insufficient for a cor-
rect Lateral Runout measure-
ment.
Error in Radial and Lateral Sonar
reading. No value was read by
the Radial and Lateral Sonars.
Error in the Radial and Lateral
Sonar reading. The values taken
by the Radial and Lateral Sonars
are insufficient for a correct
Runout measurement.
Printer Not Connected.
Check
1. Before taking the measurement, make sure that the RADIAL
RUNOUT SONAR is properly positioned.
2. Check that the wheel doesn’t stop before making at least 4 to 5
complete turns after the first breaking impulse.
3. Check belt tightening.
4. Fit a medium-sized wheel (14” x 5-3/4”) and execute an eccentricity
measurement. If error 55 doesn’t take place anymore, it means that
the inertia of the wheel that gave the problem is the cause of the
wheel stopping before the acquisition of the minimum number of
values necessary for a reliable runout measurement.
1. Before taking the measurement, make sure that the LATERAL
RUNOUT SONAR is properly positioned.
2. Check the LATERAL RUNOUT SONAR connection. Unplug and
replug at power PCB.
3. Check the power supplies on the power board.
4. Replace the Lateral Runout Sonar.
5. Check that the wheel doesn’t stop before making at least 3 com-
plete turns after the first braking pulse.
6. Check the belt tightening.
7. Replace the PC board.
1. Before taking the measurement, make sure that the LATERAL
RUNOUT SONAR is properly positioned.
2. Check that the wheel doesn’t stop before making at least 3 com-
plete turns after the first braking pulse.
3. Check the belt tightening.
4. Fit a medium-sized wheel (14” x 5-3/4”) and execute a lateral runout
measurement. If error 57 doesn’t take place anymore, it means that
the inertia of the wheel that gave the problem is the cause of the
wheel stopping before the acquisition of the minimum number of
values necessary for a reliable runout measurement.
1. Check actions in Error 54.
2. Check actions in Error 56..
1. Check actions in Error 55.
2. Check actions in Error 57..
1. Check serial connector at computer PCB.
2. Check serial connections inside cabinet at wire tray.
