Safety

DANGER

Hazard due to lack of effectiveness of the protective device
Persons and parts of the body to be protected may not be recognized in case of non-
observance.

b

Maintenance work, alignment work, fault diagnoses, and any changes to the inte‐
gration of the protective device in the machine must only be carried out by quali‐
fied personnel.

b

The effectiveness of the protective device must be checked following such work.

DANGER

Hazard due to lack of effectiveness of the protective device
Persons and parts of the body to be protected may not be recognized in case of non-
observance.

b

Make sure that the optical properties of the front screens of the twin sticks are not
changed, e.g., by:

°

beading water, mist, frost, or ice formation. If applicable, remove films or
other types of contamination, disconnect the voltage supply of the twin stick
and then switch it back on.

°

Scratches or damage. Replace the device if the front screen is scratched or
damaged.

b

Make sure that all reflective surfaces and objects maintain a minimum distance
from the protective field.

b

Make sure that no dispersive media (e.g., dust, fog, or smoke) are within the calcu‐
lated minimum distance from the protective field.

NOTE

This document does not provide information on operating the machine in which the
safety light curtain is integrated.

9.2

Regular thorough check

The check must detect if it is possible to enter the hazardous area without being
detected. Such possibilities may exist due to modifications, manipulations or external
influences.

b

Carry out the checks according to the instructions from the manufacturer of the
machine and from the operating entity.
