Prerequisites
•
N
o obstacles interfere with the view in the protective field of the safety laser scan‐
ner. Where there are unavoidable obstacles, additional protective measures are
applied.
•
If people can stay between the protective device and the hazardous point without
being detected, additional protective measures (e.g. restart interlock) are applied.
•
Reaching under, over and around, crawling beneath and stepping over the safety
laser scanner, as well as moving it, are prevented.

Complementary information
Certain optical and electromagnetic ambient conditions can affect the safety laser
scanner and thus reduce the availability of the machine.
Examples:
•
Condensation on the optics cover
•
Strong electrical fields (e.g. welding cables or induction cables)

4.3.1 Protection from influences
Influence by laser
L
aser sources located close to the machine can influence the safety laser scanner and
thus reduce the availability of the machine.
Measures to increase availability:
b
Avoid laser sources in the scan plane.
b
Set multiple sampling to the highest value permitted in your application, taking the
minimum distances into account, see "Multiple sampling", page 64.
