2 Intended use
The WLG16 is an opto-electronic photoelectric retro-reflective sensor (referred to as
“sensor” in the following) for the optical, non-contact detection of objects, animals, and
persons. A reflector is required for this product to function. If the product is used for any
other purpose or modified in any way, any warranty claim against SICK AG shall become
void.
Photoelectric retro-reflective sensor with optional add-on for detecting transparent

4 Mounting
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 < 1,3 Nm.
5 Electrical installation
The sensors must be connected in a voltage-free state. The following information must
be observed, depending on the connection type:
– Male connector connection: Note pin assignment
– Cable: wire color
Only supply/switch on the voltage once all electrical connections have been estab‐
lished.

6 Additional functions
Alarm
Alarm output: The sensor (WLG16) features a pre-failure notification output (“Alarm” in
connection diagram [see table 5]), which issues a notification if the sensor is only ready
for operation to a limited extent. The LED indicator flashes in this case. Possible
causes: Sensor or reflector is contaminated, sensor is out of alignment. In the good
state: LOW (0), if excessively contaminated HIGH (1).
Health
Health output: The sensor (WLG16) features a pre-failure notification output (“Health”
in connection diagram [see table 5]), which issues a notification if the sensor is only
ready for operation to a limited extent or the cable has been interrupted. Possible
causes: Sensor or reflector is contaminated, sensor is out of alignment, cable is dam‐
aged. In the good state: HIGH (1), if excessively contaminated or in the event of cable
interruption LOW (0). The yellow LED indicator flashes in this case.

Test input
Test input: The WLG16 sensors feature a test input (“TI” or “Test” on the connection
diagram [see table 2, table 3 and table 6]), which can be used to switch the sender off
and, therefore, check that the sensor is functioning correctly: If female cable connec‐
tors with LED indicators are used, you have to ensure that the TI is assigned accord‐
ingly.
It is important that there is no object between the sensor and reflector; activate the test
input (see the connection diagram [see table 2, table 3 and table 6]). The send LED is
shut down or the detection of an object is simulated. Refer to table 6 to check the func‐
tion. If the switching output fails to behave in accordance with table 6, check the appli‐
cation conditions. See section Fault diagnosis.

7 Commissioning
1Alignment
Align the sensor with a suitable reflector. Select the position so that the red emitted 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 [figure 1]. You must ensure that the optical open‐
ings of the sensor and reflector are completely clear.

2Sensing range
Adjust the distance between the sensor and the reflector according to the corresponding
diagram [see figure 2].

Sensing range setting
The teach-turn adjustment is used to set the object mode and switching threshold, see
figure 3, see figure 4.
The WLG16 is equipped with AutoAdapt technology. The switching threshold is automati‐
cally adjusted in the event of contamination or after cleaning.
•Turn the press-turn element (without pressing) to set the desired object mode. A blue
LED indicator lights up according to the set object mode.
•Press the press-turn element for about 1 to 3 seconds to set the switching threshold.
If mode 1 to 4 is selected, the yellow LED indicator lights up when the reflector is in
view of the sensor.
•Lead the object into the path of the beam. The yellow LED indicator goes out, mean‐
ing the object is detected and the setting is correct.
•With object selection 5, the film must be in the path of the beam when the poten‐
tiometer is pressed. The yellow LED indicator does not light up until the film is no
longer in the beam path. When this has been checked, the setting is correct.
•The blue LED indicator of mode M lights up when a setting has been selected via IO-
Link which deviates from the predefined parameter sets of modes 1-5. This mode
cannot be selected directly on the device.
