Check the protective device for damage or wear, particularly the mounting, the electrical
c
onnection and the connection cable, the housing and the front screen.
Check whether the access to the hazardous area is only possible by interrupting the light
path between sender and receiver (e.g. correct mounting of mechanical protective
devices).
Check whether the protective device is effective for the set operating mode.
6.2.3 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 major changes have been made to the machine or the protective device, or if the
single-beam photoelectric safety switch has been modified or repaired, check the plant
again as per the checklist in the annex.
