The center of detection is constantly cleaned for stable detection, even with Japanese paper, etc., that generates a large amount of dust.
The top lens is also cleaned by the “spring effect" of work caused by release of tension that occurs when the work runs out.

The output transistor turns off when load short circuit or overload occurs. Check the load and turn the power back on.
