Maintenance and overhaul
In order to make the photoelectric switch work stably for a long time, like the general controller, please carry out the
following regular inspections:
1. Check whether the installation position of the detection object and the photoelectric switch is offset, loose or deformed;
2. Check the wiring and connection parts for looseness, poor contact and disconnection;
3. Check whether there are deposits such as metal dust adhered to the detection surface;
4. Check whether the operating temperature and ambient conditions are abnormal;

Precautions 
1. This product cannot be used when the power is turned on (within 200ms);
2. The detected object must be an opaque detection body.
3. When two through-beam photoelectric switches are installed together at the same time, there may be mutual interference
between the photoelectric switches. Please change the position between the transmitter and the receiver to avoid mutual
interference disturb.
4. Please be sure to connect the circuit correctly to avoid damage to the product.
