3.2.4 Device components
The SafeZone safety laser scanner comprises three components:
• The sensor head with the opto-electronic acquisition system
• The I/O module, this defines the functionality of the SafeZone safety
laser scanner
• The system plug with the configuration memory (the system plug
contains all electrical connections)

3.3 Applications
3.3.1 Stationary applications
Hazardous area protection
On dangerous stationary machines, the SafeZone safety laser scanner
switches the output signal switching devices (OSSDs) to the off status if
the protective safety field is interrupted. The SafeZone safety laser
scanner initiates the shutdown of the machine or the shutdown of the
dangerous state.

Hazardous area protection with multiple monitored areas
(position-related protective safety field switching)
Using the SafeZone safety laser scanner, you can define up to four
monitoring cases to match the protective safety field and warning field to
the situation on the machine and to monitor changing hazardous areas~e.g.
during different machine production phases~depending on the situation.

Interior protection
On large machines the SafeZone safety laser scanner can be used to
protect the interior. The machine can only be restarted if the SafeZone
safety laser scanner does not detect any object in the protective safety
field. This is particularly important for interiors that can only be seen
with difficulty from the outside, or cannot be seen at all.
