•
The safety laser scanner must be affixed so that no small objects (e.g. cables) are
in the protective field, even if the safety outputs do not switch to the OFF state as a
result.
•
The safety laser scanner must be affixed so that no obstacles disrupt the safety
laser scanner’s field of view. Take additional protective measures if a risk arises
due to unavoidable obstacles.
•
If people can stay between the protective device and the hazardous point without
being detected, check if additional protective measures (e.g. restart interlock) are
required.
•
Reaching under, over and around, crawling beneath and stepping over the safety
laser scanner, as well as moving it, must be prevented.

Protection from influences
A safety laser scanner can be influenced by the beams from a different laser source
in close proximity to it, e.g. by another laser scanner. This may impair the machine’s
availability. That is to say, the affected safety laser scanner switches the machine off,
although no people are situated in the protective field.
A safety laser scanner may be dazzled by a strong external light source in the scan
plane. This may impair the machine’s availability. That is to say, the safety laser scanner
switches the machine off, although no people are located in the protective field.
You can use the following measures to increase the availability:
