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.
■
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 Class 2 source of supply.
UL Environmental Rating: Enclosure type 1
2 Intended use
The WLA16 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.

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 (WLA16) features a pre-failure notification output (“Alarm” in
connection diagram 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 (WLA16) 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 WLA16 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 [see figure 1]. You must ensure that the optical
openings of the sensor and reflector are completely clear.
Figure 1: Alignment 1 Figure 2: Alignment 2
2Sensing range
Adjust the distance between the sensor and the reflector according to the corresponding
diagram [see figure 3] (x = sensing range, y = operating reserve).

16 Montage
Sensor und Reflektor an geeignete Befestigungswinkel montieren (siehe SICK-Zubehör-
Programm). Sensor und Reflektor zueinander ausrichten.
Maximal zulässiges Anzugsdrehmoment des Sensors von < 1,3 Nm beachten.
17 Elektrische Installation
Anschluss der Sensoren muss spannungsfrei erfolgen. Je nach Anschlussart sind die
folgenden Informationen zu beachten:
– Steckeranschluss: Pinbelegung beachten
– Leitung: Adernfarbe
Erst nach Anschluss aller elektrischen Verbindungen die Spannungsversorgung anlegen
bzw. einschalten.
