Through-beam photo switches



After mounting the photo-switch the light beam can be adjusted using 3 screws.
Important note!
The optical sensor is spring-mounted. All 3 screws are unscrewed by 1 turn factory-made, the maximum is 3 turns.
The optical sensor is optimally align when the green LED lights up constantly.

LED lights up

LED lights up: 100% of the cone of light is hitting the reflector


LED flashing

LED flashing: less than 100% of the cone of light is hitting the reflector
