Product self-inspection steps

1. Detect whether the installation position of the object and the proximity sensor has deviated, slacked, or skewed; whether there is slack, poor contact, or disconnection in the wiring and connection parts
2. Whether there is adhesion or accumulation of metal dust, etc.
3. Is there any abnormality in using temperature conditions and environmental conditions?
4. Set whether the flashing of the display lamp type is abnormal.
Suppose you must be careful not to disassemble and repair by yourself during the inspection, and to easily find out the fault. In that case, you can investigate the operating state of the sensor through the connection with the portable detector, and then repair it according to the situation.

In order to make the photoelectric sensor work stably for a long time, it should be regularly checked with the same contents as the general control equipment to maintain its long-term function. The photoelectric sensor can also be stocked. Once a problem with the photoelectric sensor is found, we can replace it in time without affecting the use of the sensor.
