2 Mount the sensor and the reflector using suitable mounting brackets (see the SICK
range of accessories). Align the sensor and reflector with each other.
Note the sensor's maximum permissible tightening torque of 0.8 Nm.
3 The sensors must be connected in a voltage-free state (V
in the graphics [B] must be observed, depending on the type of connection:
– Male connector connection: pin assignment
– Cable: core color
Technical data and wiring diagrams from page 61.

Explanations of the connection diagram (Graphic B):
Switching outputs Q and /Q (according to Graphic B):
Teach = external teach-in (ET) (see Adjustment)
WLG4S-3Exxxx and WLG4S-3Fxxxx
D: dark switching, output (Q) switches on when an object is present in the path of
the beam.
WLG4S-3Exxx4 and WLG4S-3Fxxx4
Output Q. In addition: ET: teach-in function via cable.
WLG4S-3Vxxxx and WLG4S-3Wxxxx
Output Q, in addition, alarm output. Alarm output switches on when the continuous
threshold adaptation can no longer be adapted to the ambient conditions (e.g., the
reflector is too contaminated).
4 Align the sensor with a suitable reflector. Select the position so that the red emit‐
ted light beam hits the center of the reflector. The sensor must have a clear view of
the reflector, with no object in the path of the beam [see E]. You must ensure that
the optical openings of the sensor and reflector are completely clear.
