Sensing range setting
Sensor which it is not possible to set: The sensor is adjusted and ready for operation.
The sensing range is adjusted with the potentiometer (type: 270°). Clockwise rotation:
sensing range increased; counterclockwise rotation: sensing range reduced. We recom‐
mend placing the object within the sensing range, e.g.
range has been adjusted, the object is removed from the path of the beam, which
causes the background to be suppressed and the switching output to change
