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 [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
[H15] as follows:
Example: x = 1,000 mm, y = 20 mm. That is, the background is suppressed at a dis‐
tance of > 20 mm from the sensor.

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 [B] must be observed, depending on the connection type:

3.4 Functioning of the programmable input
Value Notes
PNP mode Deactivated < 5.0 V Also deactivated when not connected
Active > 10.0 V Max. applied voltage not higher than
UV
NPN mode Deactivated > 10.0 V Max. applied voltage not higher than
UV
Active < 4.0 V Also active when not connected
The programmable input must be active for the durations specified below (e.g., U
> 10.0 V in PNP mode ) in order to set the corresponding functions. For a description of
the available functions and how to select them via the menu, see "Setting the switching
outputs and other sensor configurations via the menu", page 8

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.

4 Configuration
Perform configuration:
4.1 Setting the switching output via the teach-in quick access button (-/Q1) (+/Q2)
(Set/Q3)
The sensing range is adjusted by pressing the teach-in quick access button for > 1 s.
NOTE
The teach-in quick access button (Set/Q3) is only active if the OUT option has previously
been selected in the MF menu item. See section chapter 4.2 for more information
COMMISSIONING 3
8020034.17U4 | SICK
Subject to change without notice 7

Do not operate the teach-in buttons using sharp objects. We recommend placing the
switching 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, which causes the back‐
ground to be suppressed and the switching output to change (see Graphic C).
The sensor is adjusted and ready for operation. Refer to Graphic C to check the func‐
tion. If the switching output fails to behave in accordance with Graphic C, check the
application conditions. See section chapter 5.

4.2 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/Q3 button for < 1 s. Graphic K describes how to navigate within the
menu.
