Sensing range setting
Sensor with potentiometer: open the sensor cover and protective hood, make sure that
no dirt has gotten into the device.
The sensing range is adjusted with the potentiometer (type: without stop ). Clockwise
rotation: sensing range increased; counterclockwise rotation: sensing range reduced.
We recommend placing the object within the sensing range, e.g. see
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
figure 6
and
figure
7].
Table 8: Sensing range setting
The sensor is adjusted and ready for operation.

Time function setting
WT34: no time delay, t1 = time delay, t2 = time delay; for -R: 0 = relay deactivated,
1 = relay active. Time delay selector switch can be set on the device according to the
following graphic.
