5. Set-up and maintenance
5.1 Functional testing
The safety function of the safety components must be tested. The
following conditions must be previously checked and met:
1. Correct fixing of the transmitter and receiver.
2. Fitting and integrity of the power cable.
3. If one or more light barriers are interrupted, the hazardous
movement is brought to standstill.
5.2 Maintenance
In the case of correct installation and adequate use, the safety switch-
gear features maintenance-free functionality. A regular visual inspection
and functional test, including the following steps, is recommended:
1. Check the correct mounting of the fixing screws on the safety
light barriers.
2. Clean the optics of transmitter and receiver with a soft clean cloth.
The use of agressive, abrasive or scratching cleaning agents,
which could attack the surface, is prohibited
Damaged or defective components must be replaced.
6. Disassembly and disposal
6.1 Disassembly
The safety switchgear must be disassembled in a de-energised
condition only.
