azard due to lack of effectiveness of the protective device
Persons and parts of the body to be protected may not be recognized in case of non-
observance.
Do not operate the machine if the OUT LED lights up green or the RES LED flashes
orange during the check!
b
If the OUT LED lights up green or the RES LED flashes orange during the test, even
if only briefly, work must stop at the machine.
b
In this case, the mounting and configuration of the safety light curtain must be
checked by qualified safety personnel (siehe "Mounting", Seite 44).
b
Before inserting the test rod, check whether the OUT LED lights up green if the
reset function is deactivated or the RES LED flashes orange if the reset function is
configured (“reset required”). If this is not the case, this status must first be
induced. The check is otherwise meaningless.
Approach
1.
Move the test rod slowly through the area to be protected (e.g., machine opening),
as indicated by the arrow, see figure 31.
2. Watch the OUT LED and the RES LED during the check. The OUT LED should con‐
tinuously light up red. The RES LED must not flash orange.

y the arrow, see figure 32.
4. Watch the OUT LED and the RES LED during the check. The OUT LED should con‐
tinuously light up red. The RES LED must not flash orange.
