Remarks
 Approved purpose
The diffuse reflection light scanners are optical electronic sensors for optical, contactless detection of
objects. This product may only be used by qualified personnel and must only be used for the approved
purpose. This sensor is not a safety sensor and is not to be used for the protection of persons.

Sensor OFF
In the areas between "Sensor OFF"
and the operating range, the sensor
functions with only a low perfor-
mance reserve. The sensor typically
flashes in this case. Depending on
the tolerance, it is, however, also
possible that the sensor no longer
detects objects.
