Commissioning
8.3.1 Tests before the initial commissioning
Check the effectiveness of the protective device mounted to the machine, using all
selectable operating modes as specified in the checklist in the annex (see 14.2 on
page 119).
Ensure that the operating personnel of the machine protected by the safety light curtain
are correctly instructed by qualified safety personnel before being allowed to operate
t
he machine. Instructing the operating personnel is the responsibility of the machine
owner.
Annex 14.2 to this document includes a checklist for review by the manufacturer and
OEM. Use this checklist as a reference before commissioning the system for the first
time.
8.3.2 Regular inspection of the protective device by qualified safety personnel
Check the system following the inspection intervals specified in the national rules and
regulations. This procedure ensures that any changes on the machine or manipulations
of the protective device after the initial commissioning are detected.
If any modifications have been made to the machine or the protective device, or if the
safety light curtain has been changed or repaired, the system must be checked again as
specified in the checklist in the annex.
8.3.3 Daily functional checks of the protective device
The effectiveness of the protective device must be checked daily by a specialist or by
authorised personnel, using the correct test rod.
Always test along the complete hazardous area to be protected, never solely at the mount-
ing position of the safety light curtain.
Do not operate the machine if the red LED does not light up during the test!
If the red LED does not light up during the test, work must stop at the machine. In this
case the mounting and the configuration of the safety light curtain must be checked by
qualified safety personnel (see chapter 6).
Before interrupting the protective field or before inserting the test rod, check that the
green LED is lit if the internal restart interlock is deactivated and that the yellow LED is
flashing if the internal restart interlock is activated (“Reset required”). If this is not the
case, ensure that this condition is reached. The test is otherwise meaningless.
How to check the effectiveness and correct function of the safety light curtain in
horizontal applications:
The output signal switching devices on the safety light curtain must shut off once every
24 hours, i.e. the LEDs must illuminate red. For this purpose interrupt the protective
field from the top, in the middle, not in the entry or exit area. In this case the brief illu-
mination of the red LEDs indicates the shut down of the OSSDs.
It is not necessary to test individual beams.
