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.

Time function setting
WT24-2xx2x, WT24-2xx5x: 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
