Subject to change without notice
WT(B)23-2xxx2x: Align the sensor with the object. Select the position so that the
infrared light (not visible) hits the center of the object. The correct alignment can
only be detected via the LED indicators. Please refer to Graphics C and E. You must
ensure that the optical opening (front screen) of the sensor is completely clear. We
recommend making the adjustments using an object with a low remission.

5 Sensor which it is not possible to set (WT(B)23-2Xxxx0): The sensor is adjusted and
ready for operation.
Refer to Graphics C and G to check the function. If the switching output fails to
behave in accordance with Graphic C, check application conditions. See section
Fault diagnosis.
Sensor with potentiometer (WT(B)23-2Xxxx1):
The sensing range is adjusted with the potentiometer (type: 270°). Clockwise rota‐
tion: sensing range increased; counterclockwise rotation: sensing range reduced.
We recommend placing the switching state in the object, e.g., see Graphic F. Once
the sensing 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 (see Graphic C).
The sensor is adjusted and ready for operation. Refer to Graphics C and G to check
the function. If the switching output fails to behave in accordance with Graphic C,
check application conditions. See section Fault diagnosis.
Sensor with teach-in button (WTE23-2Xxxx2):
The sensing range is adjusted by pressing the teach-in button. Do not operate the
teach-in button using sharp objects. We recommend placing the switching state in
the object, e.g., see Graphic F. Once the sensing 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 (see Graphic C).
