1. Mount the sensor using a suitable mounting bracket (see the SICK range of
accessories).
2. Note the sensor’s maximum permissible tightening torque of 0.5 Nm.
3. Select the position so that the infrared light (not visible) hits the center of the
object. The correct alignment can only be detected via the LED indicators (yellow
indicator LED lights up when the object is detected) or with the help of an infrared
conversion screen (see the SICK range of accessories).
see figure 9, page 25
4. Note the preferred direction of the object relative to the sensor. see figure 10,
page 26
5. Adjust the sensing range and distance to the object or background and the remis‐
sion capability of the object.
see figure 11, page 26
6. You must ensure that the optical opening (front screen) of the sensor is completely
clear.
NOTE
The minimum distance for background suppression can be read as follows. Example:
Sensing range (= x axis) to a bright object is 400 mm. A dark background is suppressed
at a distance of 85 mm or more behind the object.
