Regular checks and maintenance

9.1

Checks

9.1.1

Regular checks

The aim of these regular checks is to uncover any changes to the plant/machine, safe-
guards and ambient conditions.

9.1.2

Daily check

The safety light grid must undergo a function test once a day (e.g. when starting work, after
a shift change).

INFORMATION

This inspection may only be carried out by qualified personnel.

Check the safety function of the safety light grid as follows:
Violate the protected field. The indicator light unit must change from green to red and the
movement causing the hazard must be switched off.

9.1.3

Check after plant/machine modification

Check the safety light grid each time the plant/machine is modified. Changing the safety
light grid or swapping safety light grid components should be regarded as a modification. 
The requirements of the applicable national regulations must be observed 

absolutely

.

INFORMATION

This inspection may only be carried out by qualified personnel.

The Appendix contains a Checklist which should help you perform the safety check.

9.2

Maintenance

Other than cleaning the lens covers, the safety light grids requires no other form of main-
tenance.

CAUTION!

Improper cleaning agents can damage the safety light grid and lead to mal-
functions
