1 Safety information

1.1 General safety notes

■

Read the operating instructions before commissioning.

■

Connection, mounting, and setting may only be performed by trained spe‐

cialists.

■

Not a safety component in accordance with the EU Machinery Directive.

■

When commissioning, protect the device from moisture and contamination.

■

These operating instructions contain information required during the life cycle of
the sensor.

1.2 Notes on UL approval

The device must be supplied by a limited voltage / limited current circuit or is intended
to be connected to a Class 2 source of supply. In case of a limited voltage / limited cur‐
rent circuit the device shall be supplied from an isolating transformer having a sec‐
ondary overcurrent 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).

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 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
objects (WLG-xx).

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 (UV = 0 V). The following informa‐
tion must be observed, depending on the connection type:

– Male connector connection: Note pin assignment
– Cable: wire color

Only apply voltage/switch on the voltage supply (UV > 0 V) once all electrical connec‐
tions have been established.

Explanations of the connection diagram (Tables 1 and 2):

Alarm = alarm output (see Table 4)

Health = alarm output (see Table 4)

MF (pin 2 configuration) = external input, teach-in, switching signal

QL1 / C = switching output, IO-Link communication

Alarm

Alarm output: The sensor (WLG16) features a pre-failure notification output (“Alarm” in
connection diagram [Table 4]), 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 [Table 4]), 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 damaged. In
the good state: HIGH (1), if excessively contaminated or in the event of cable interrup‐
tion LOW (0). The yellow LED indicator flashes in this case.

6 Commissioning

Bluetooth® is switched on for initial commissioning. You can get SOPASair in the Google
PlayStore (Android) and in the App Store (iOS).
Operating system requirements: Android version 6.0, most current version of iOS.

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 3]. You must ensure that the optical
openings of the sensor and reflector are completely clear.

Figure 3: Alignment

2 Sensing range

Adjust the distance between the sensor and the reflector according to the corresponding
diagram [see figure 4].
