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].
Table 8: Sensing range setting
For WT24-2B470 (with foreground suppression): The sensing range is adjusted relative to
the background with the potentiometer. Clockwise rotation: sensing range increased; coun‐
terclockwise rotation: sensing range reduced. Turn the potentiometer clockwise until the
yellow LED indicator lights up. Afterwards, only turn the potentiometer counterclockwise as
far as is needed so that the yellow LED no longer lights up. When an object is moved into
the path of the beam, the yellow LED indicator must light up. If the yellow LED indicator
does not light up during object detection, repeat the adjustment process, or reduce the dis‐
tance between the sensor and background and then repeat the adjustment process.
The sensor is adjusted and ready for operation.
4 Time function setting
WT24-2xx2x, WT24-2xx5x: t0= no time delay, t1 = time delay, t2 = time delay; for -2R: 0 =
relay deactivated, 1 = relay active. Time delay selector switch can be set on the device
according to the following graphic.
Time stages: 0.5 ... 10 s can be adjusted.
