Ho
w 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
T
he rod test check is used to check whether the hazardous point is only accessible via
the protective field of the safety light curtain and whether the protective device is able
to identify each time the hazardous point is approached.
The test is carried out with an opaque test rod whose diameter corresponds to the
resolution of the safety light curtain.
If several safety light curtains are connected to each other in a cascade, the complete
check for every safety light curtain in the cascade is carried out. During the check,
catch the field indicator of the device you are currently testing.
Important information
DANGER
Use of incor
rect test rods
Persons or parts of the body to be protected may not be detected in operation.
b
Only use the test rod with the diameter specified on the type label of the safety
light curtain.
b
If the resolution is reduced, use the test rod that ensures effective resolution of
the safety light curtain.
DANGER
H
azard 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 safety light curtain have no effect on the
machine during the check of the components.
DANGER
H
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 field indicator lights up green or yellow during the
check!
b
If the field indicator lights up green or yellow during the check (even if only briefly)
work must stop at the machine.
b
In this case, the mounting and electrical installation of the safety light curtain
must be checked by qualified safety personnel.
NOTE
T
he integrated laser alignment aid switches the OSSDs to the OFF status.
b
Ensure that the integrated laser alignment aid is switched off during the check.
