Sensor with potentiometer:
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.
