SICK safeVisionary2 - Approach Direction; Orthogonal Approach to the Optical Axis, Example 1

Complementary information
In some c
ases, it is not possible to define when to switch (for example because
processing times of the machine vary) or the time advance means that the monitoring
of an area finishes too early.
Remedial measures:
•
Allow both protective fields to partially overlap.
•
Temporarily monitor both hazardous areas simultaneously.

4.3.8 Approach direction
Overview
A per
son can approach the protective field orthogonally or parallel to the optical axis.
The calculation of the minimum distances differs depending on the approach direction.
Orthogonal approach to the optical axis
W
hen approaching orthogonally to the optical axis, a person approaches the protective
field from the side.
