User notice
1. The receiving module J4 in the above figure is the selection switch of the photoelectric switch normally open and normally closed.
2. When the short-circuit cap on NO.it is normally open.
3. When the shorting cap on NC.jt is normally closed
4. Installation
5. The photocell should be installed above 20cm from the ground (to avoid reflection), and the distance between the transmitter and receiver should be greater than 50cm.
6. The end user should install the photocell receiver on the back of direct sunlight or other strong light sources (±5-) to keep the photocell working stably.
7. Avoid installing other infrared photocell transmitters within the effective distance of the receiver.
8. If the end user needs to install other photocells in the same line, the receiver can be installed at both ends, and the transmitter can be installed back to back.
9. The installation is stable, which can avoid the signal skew of the transmitter and receiver due to slight vibration and misoperation.
10. When the product is installed in an angled place, the end user can adjust the PCBA to make the installation better.
11. Turn on the power after checking. When the shorting cap is NO, install the battery on the LED light of the transmitter module, the LED light turns on for 0.5 seconds and then goes out, the receiving module LED is on, and the receiver module contacts are closed; when the transmitter and receiver When the cover of the receiver is aligned, the receiver module LED will be off and NC/NO will be on; when something or someone obstructs the sensor, the receiver module LED will be on and the NC/NO contact will be closed. When the cap is short-circuited at the NC, the state of NO/NO is opposite to the above phenomenon.
