The PowerProx Small Teach-in - WTT190LC-B2233A00 is an opto-electronic photoelec‐
tric proximity sensor (referred to as “sensor” in the following) for the optical, non-con‐
tact detection of objects. If the product is used for any other purpose or modified in any
way, any warranty claim against SICK AG shall become void.

3 Commissioning
3.1 Check the application conditions:
Check the application conditions: Adjust the sensing range and distance to the object
or background and the remission capability of the object according to the correspond‐
ing diagram [see H1, H2] (x = sensing range, y = minimum distance between the object
and background in mm (object remission / background remission)). Remission: 6% =
black, 90% = white (referring to standard white as per DIN 5033).
The minimum distance (= y) for background suppression can be read from diagram the
diagram [see H15] as follows:
Example: x = 1,000 mm, y = 20 mm. That is, the background is suppressed at a
distance of > 20 mm from the object.

3.2 Mounting
Mount the sensor using a suitable mounting bracket (see the SICK range of acces‐
sories).
Note the sensor's maximum permissible tightening torque of 0.8 Nm.
Note the preferred direction of the object relative to the sensor [F].
3.3 Electronics
The sensors must be connected in a voltage-free state (UV = 0 V). The information in
the graphics must be observed, depending on the connection type:
– Male connector connection: pin assignment
– Cable: Wire color

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

3.5 Alignment
Align the sensor with the object. Select the position so that the red emitted light beam
hits the center of the object. You must ensure that the optical opening (front screen)
of the sensor is completely clear [F]. We recommend making the adjustments using an
object with a low remission.
Figure: E
4 Configuration
Perform configuration:
4.1 Setting the switching output via the teach-in quick access button (-/Q1) (+/Q2)
The sensing range is adjusted by pressing the teach-in quick access button for > 1 s.
Do not operate the teach-in buttons using sharp objects. We recommend placing the
sensing range in the object, e.g., see Graphic F. Once the sensing range has been
adjusted, the object is removed from the path of the beam. This causes the background
to be suppressed and the switching output to change.
Sensing range settings via IO-Link. See IO-Link description (8022709).
The sensor is adjusted and ready for operation. Use the following graphic to check the
function. If the switching output fails to behave in accordance with the graphic, check
the application conditions. See section Fault diagnosis chapter 5.

4.3 Setting the switching outputs and other sensor configurations via the menu
As an alternative, the switching outputs can also be set via the menu. Further sensor
configurations can also be performed via the menu. The menu is accessed by briefly
pressing the Set button for < 1 s. Graphic K describes how to navigate within the menu.
NOTE
Entries qn1 and qn2 are only available when the accompanying teaching mode (qc1,
qc2) has been set to 2-point or window mode.
