About maintenance and overhaul
In order to keep the proximity sensor to work stably for longtime,
the following regular examinations should be performed just like
general control
1. Check the installation position of detected object and proximity
sensor if any deviation,loosening or deformation exists.
2. Check the attached wires and connecting parts if any
loosening,bad contact or wire breaking off exists.
3. Check if there is any metallic powder accumulation or not.
4. Check if the temperature condition and surrounding environment
condition are normal or not.
5. Check if the detection distance is normal or not.
