1 Safety information
1.1 General safety notes
■Read the operating instructions before commissioning.
■
Connection, mounting, and configuration may only be performed by trained
specialists.
■
2006/42/EC
NO
SAFETY
Not a safety component in accordance with the EU Machinery Directive.
■
Do not install the sensor at locations that are exposed to direct sunlight
or other weather influences, unless this is expressly permitted in the operating
instructions.
■These operating instructions contain information required during the life cycle of
the sensor.
1.2 Notes on UL approval
The device shall be supplied from an isolating transformer having a secondary overcur‐
rent protective device that complies with UL 248 to be installed in the field rated either:
a) max 5 amps for voltages 0 ~ 20 V (0 ~ 28.3 V peak), or
b) 100 / Vp for voltages of 20 ~ 30 V (28.3 ~ 42.4 V peak).
Alternatively, they can be supplied from a Class 2 power supply.
UL Environmental Rating: Enclosure type 1
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 it 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.
WLG16 is a photoelectric retro-reflective sensor with optional add-on for detecting
transparent objects.

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 2]), which issues a notification if the sensor is only ready
for operation to a limited extent. The LED flashes in this case. Possible causes: Sensor
is contaminated, sensor is out of alignment. In the good state: LOW (0), if excessively
contaminated HIGH (1).
Health output: The sensor (WLG16) features a pre-failure notification output (“Health”
in connection diagram [see table 2]), 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 [table 2], which can be used to switch the sender off and, therefore, check that
the sensor is functioning correctly: If female cable connectors with LED indicators are
used, you have to ensure that the TI is assigned accordingly.
It is important that there is no object between the sensor and reflector; activate the
test input (see the connection diagram). The send LED is shut down or the detection
of an object is simulated. Refer to table 6 to check the function. If the switching output
fails to behave in accordance with the graphic, check the application conditions. see
„Troubleshooting“, page 14

7 Commissioning
7.1 Alignment
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 [see figure 1]. You must ensure that the
optical openings of the sensor and reflector are completely clear.

7.3 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 automat‐
ically adjusted in the event of contamination or after cleaning.
