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 launch.
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 Overfl 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.
30 Error in clock control on the screen.
40 ÷ 53 Error in control of eccentricity measurement graphs
