9 MAINTENANCE AND REPAIR
9.3.6 Cleaning the Encoder
The measuring wheel of the incremental encoder must have direct and steady contact with
the conveyor belt and must turn without any slipping.
Contamination on the measuring wheel or damaged rubber rings can cause faulty behavior
of the incremental encoder.
Fig. 41: Visual inspection of the incremental encoder
▸ Remove any contamination on the measuring wheel of the incremental encoder.
▸ Replace damaged rubber rings.
▸ Check the wear of the measuring wheel.
Note
If it is so badly worn that contact with the conveyor belt is impaired, the incremental
encoder must be replaced
