Sensing range adjustment
WTB4F-xxxxxx1x
Adjustment via a potentiometer:
Clockwise rotation: Sensing range increased.
Counterclockwise rotation: Sensing range reduced.
WTB4F-xxxxxx2x
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.
