3.3.3 Other applications (not for personnel protection)
Along with safety-related applications, you can also use the SafeZone safety
laser scanner for applications in which people do not need to be protected.
Collision protection
Along with people, you can also protect vehicles from colliding with
other objects.
Figure 12: Collision protection
As soon as vehicle  reaches the warning field of vehicle Œ, vehicle Œ slows
down. When vehicle  reaches the protective safety field of vehicle Œ,
vehicle Πstops.
Currently there are two SafeZone variants offered. The SafeZone
Singlezone is offered with a 4 meter protective safety field range and
Single field set (Warning and protective safety fields) and the SafeZone
Multizone is offered with a 5 meter protective safety field and up to four
configurable field sets.

3.4 Configurable functions
3.4.1 Field sets
Configuring the protective safety field and warning field
• The protective safety fields ( Œ) can cover up to 190° and have a radius
of up to 4 or 5 m.
• The warning fields ( ) can cover up to 190° and have a radius of up to
49 m. Detection is dependent on the reflectivity (e.g. objects with a
reflectivity of 20% can be detected in a radius of up to 20 m).

Typical Application Functionality Required
Protection of a robot insertion station One field set
Protection of a pipe bending machine Up to four switchable field sets
Protection of a material processing system‘ Up to four switchable field sets
Œ

Protection of an automated guided vehicle AGV
with bi-directional travel In each direction of travel up to four switchable
field sets
With the aid of the SCD software you can configure
the field set, which comprises a protective safety field
and a warning field. During this process you
configure the shape and size of the protective safety
field and the warning field. You can realize any field
shape required.

IMPORTANT The area to be monitored is scanned
radially by the SafeZone safety laser
scanner. The SafeZone safety laser
scanner cannot “see around a corner.”
The area behind objects that are in the
area to be monitored (pillars, columns,
etc.) can thus not be monitored.
