Visual check of the machine and the protective device
,
•
How often does the check have to be carried out?
•
Do the machine operators have to be notified of the check and do they need to be
instructed accordingly?
b
Define all guidelines for the check.
4.5.1
Test rod check
Overview
The light beam is covered with an opaque test rod (minimum diameter of 30 mm).
When the light beam is covered, the OSSD LED on the receiver must light up red. The
check is carried out for each light beam and at multiple positions between the sender
and the receiver.
Important information
DANGER
Hazard due to unexpected starting of the machine
b
Make sure that the dangerous state of the machine is and remains switched off
during the check.
b
Make sure that the outputs of the multiple light beam safety device do not affect
the machine during the check.
DANGER
Hazard 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 OSSD LED lights up green during the test!
b
If the OSSD LED lights up green during the test, even if only briefly, work must stop
at the machine.
b
In this case, the mounting and electrical installation of the multiple light beam
safety device must be checked by appropriately qualified safety personnel.
Prerequisites
