Sensing range setting
WTS26x-xxxxxx2xAxx with press-turn element
The sensing range is adjusted by pressing the teach-in button (approx. 1-3 sec.).
Depending 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
placing the object within the sensing range,
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
