accuracy and reliability are also ensured after maintenance work.
8.1 Maintenance schedule
1. Check the compressed air supply to the sensor at regular intervals.
2. As the only wear part, the seal lip of the ribbed cover must be replaced after a long time
in service.
 You know that the seal lip needs to be replaced if the conveying capacity drops
noticeably.

8.2 Maintenance tasks
8.2.1 Checking compressed air supply to sensor
If cleaning unit is switched on:
1. Check if air is escaping from the cleaning nozzle on the sensor.
2. If not, and if air is instead escaping only via the safety valve on the cleaning unit:
Check the complete supply line to the cleaning nozzle and check the nozzle itself for
contamination and blockage.
3. Remove the contamination.
 If this is not possible: Replace blocked hoses, connectors or nozzles.
