Test notes
6.3.1
Tests before the first commissioning
The purpose of the tests before the first commissioning is to confirm the safety require-
ments specified in the national/international rules and regulations, especially in the
Machine and Equipment Usage Directive (EU Conformity).
>
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 12.2 on
page 60).
>
Make sure that the operating personnel of the machine secured by the light curtain are
properly instructed by specialist personnel before being allowed to operate the machine.
Instructing the operating personnel is the responsibility of the machine operator.
>
Annex 12.2 of this document shows a checklist for review by the manufacturer and OEM.
Use this checklist as reference before commissioning the system for the first time.
6.3.2
Regular inspection of the protective device by qualified 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 are detected before commissioning.
>
If substantial 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.
