Subject to change without notice
Sensor with potentiometer:
The sensing range is adjusted with the potentiometer (type: with stop5-gear). Clock‐
wise rotation: sensing range increased; counterclockwise rotation: sensing range
reduced. Position the object and direct the light spot onto it. Red emitted light spot
can be detected on the object. Turn the adjustment to the minimum scanning ran‐
ge. Then increase the scanning range until the yellow LED indicator lights up. Re‐
commended: If high contrast or poorly remitting objects are detected, increase the
scanning range by adding a safety supplement of 15% of the scanning range (cf.
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/D).
The sensor is adjusted and ready for operation. Refer to Graphics C/D and G to
check the function. If the switching output fails to behave in accordance with Gra‐
phic C/D, check application conditions. See section Fault diagnosis.
