Persons and parts of the body to be protected may not be recognized in case of non-
observance.
Make sure that the optical properties of the front screens of the sender and

receiver are not changed, e.g., by:
beading water, mist, frost or ice formation. If necessary, remove any residues
°
of this type or any other form of contamination and restart the receiver.
Scratches or damage. If necessary, replace the respective sender or receiver
°

Make sure that all reflective surfaces and objects maintain a minimum distance
b
from the protective field,

NOTE
This document does not provide information on operating the machine in which the
safety light curtain is integrated.
Checking the effectiveness with the test rod
The effectiveness of the protective device must be checked daily using the test rod pro‐
vided. The diameter of the test rod corresponds to the resolution of the light curtain.
Before introducing the test rod, check if the OSSD LED illuminates green. If not, then
you must first change this status. The check is otherwise meaningless.

observance.
Only use the included test rod with the diameter specified on the type label of the
b
safety light curtain.
Do not use any test rods with a similar or the same diameter of other safety light
b
curtains.
