Important information
DANGER
Hazard due to lack of effectiveness of the protective device
Reflective surfaces and dispersive media can prevent persons or parts of the body to
be protected from being properly reflected and therefore, they remain undetected.
b
Make sure that all reflective surfaces and objects maintain a minimum distance
from the protective field.
b
Ensure that no reflective objects are in the protective field.
b
Make sure that no dispersive media (e.g., dust, fog, or smoke) are within the
calculated minimum distance from the protective field.
b
Ensure that the correct formula is used for the calculation of the minimum dis‐
tance.
b
Ensure that the minimum distance to reflective surfaces is recalculated after a
change to the scanning range configuration.
Determining minimum distance from reflective surfaces with automated calibration of
the protective field width
The minimum distance can be determined as follows:
b
Determine the distance between sender and receiver D in meters (m).
b
Read the minimum distance a in millimeters (mm) in the graph or calculate using
the respective formula to determine the minimum distance to reflective surfaces:
