3 Sensing range setting
WTS26 x-xxxxxx2 xAxx with Teach-Turn adjustment:
The sensing range is adjusted by pressing the teach-in button (approx. 1-3 sec.). Depend‐
ing on the requirements, the potentiometer can be used for fine-tuning (without pressing
the teach-in button).
Clockwise rotation: sensing range increased.
Counterclockwise rotation: sensing range reduced.
The sensing range can also be adjusted using just the potentiometer. We recommend plac‐
ing the sensing range in the object, e.g.
adjusted, the object is removed from the path of the beam, which causes the background
to be suppressed and the switching output to change
