RETRO-REFLECTIVE PHOTOELECTRIC SENSOR
SENSITIVITY ADJUSTMENT *
1|When an object enters the light axis,
the yellow status LED must go out.
If this is not the case, the sensitivity
must be adjusted.
2|Using the screwdriver, turn the potentiometer
until the yellow status LED goes out.
* Only on variants with potentiometer
