Sensor with potentiometer:
WT18-3Xxx0: The sensing range is adjusted with the potentiometer (type: 4 rotati‐
ons). Clockwise rotation: sensing range increased; counterclockwise rotation: sen‐
sing 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).
WT18-3Xxx1: Sensor with teach-in button:
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 ob‐
ject 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.
