Classification: CPC G  F | IPC F  G

Claim 2:
3. The method as claimed in claim 1, further comprising:
the first sensor element has electronic devices for outputting a signal SR proportional to the number of belt revolutions, in that the rotor revolutions of the drive motor are determined by the second sensor element and are output as a signal SM proportional to the speed of the drive motor;
the relationship between a specified number NR of belt revolutions and the motor revolutions determined for this, which is present when the drive belt is new, is calculated in the computing unit and is stored as a reference value;
the associated motor speeds are then repeatedly determined for further belt revolutions corresponding to the specified number NR and their current relationship is compared with the reference value; and
a warning or alarm signal is output by the computing device after a specified tolerance value between the current relationship and the reference value has been exceeded.
