or reflection-based measurement errors
If there is a retroreflector in the vicinity of the protective device (distance of the retrore‐
f
lector from protective field ≤6m), you must take the supplement Z
R
= 350mm into
account.
4.3.7 Hazardous area protection
Overview
T
he safety laser scanner is mounted with a horizontal scan plane in a stationary appli‐
cation. This is, for example, on a machine where the hazardous area is not completely
surrounded by a physical guard.
During hazardous area protection, the safety laser scanner detects a person’s legs. The
protective field is parallel to the direction of approach.

Complementary information
It is r
ecommended to mark the course of the protective field boundaries on the floor.
By doing this, you allow machine operators to see the protective field boundaries and
make it easier to thoroughly check the protective function at a later date.
