8 - ERRORS

ERROR MEANING

1 No rotation signal. Could be due to a faulty position transducer, or to the

motor failing to start, or to something preventing the wheel from turning.

2 During the measurement spins, wheel speed had dropped below 60

r.p.m. Check encoder functioning (see TO CHECK THE ENCODER) and

repeat the spin.

3 Error in the mathematical calculations, most probably caused by incorrect

carrying out of the self-calibration. Repeat the self-calibration. Wheel

unbalance too high.

4 Motor turning in opposite direction.

5 Guard open before start of spin.

7/8/9 Fault in the machine setup parameters.

Check for correctness of the basic setup parameters and repeat the

machine calibration. Contact Technical Service.

11 Speed too high for the measurement.

12/13/14 Overow of counters used for the measurement. Check encoder functio

ning (see TO CHECK THE ENCODER). Contact Technical Service.

15/16/17/18 Contact Technical Service.

20 Wheel stopped before having positioned it.

40 ÷ 53 Error in control of eccentricity measurement graphs
