Integration in the control
T
he safety laser scanner communicates with the machine controller as follows:
•
I/O AIDA: local outputs (OSSDs)
Protective field range
T
he safety laser scanner is available in variants with the following maximum protec‐
tive field range:
•
4.0 m
•
5.5 m
•
9.0 m

3.3.2 Connections
•
1 × connec
ting cable with male connector, M12, A-coded for voltage supply and
OSSDs
•
1 × female connector, USB 2.0 Mini-B for configuration and diagnosis

OSSD
An
OSSD is a safety switching output. The functionality of each OSSD is tested periodi‐
cally. OSSDs are always connected in pairs and must undergo dual-channel analysis for
safety reasons. An OSSD pair is formed from 2 OSSDs that are connected and analyzed
together.
3.3.3 System plug
A system plug is required to operate the safety laser scanner.
T
he base plate is the system plug (see figure 2, page 12).
The safety laser scanner’s internal configuration memory is integrated in the system
plug. The system plug and all connecting cables can remain at the installation site
when the safety laser scanner is replaced. The system plug is detached from the
defective safety laser scanner and connected to the new safety laser scanner. The
new safety laser scanner reads the configuration from the configuration memory when
switching on.
3.3.4 Field types
During operation, the safety laser scanner uses its laser beams to continuously check
whe
ther people or objects are present in one or more areas. The areas to be checked
are called fields. A distinction is made between the following field types, depending on
the application type:
•
Protective field
•
Reference contour field
•
Contour detection field

T
he USB connection may only be used temporarily and only for configuration and diagnostics.
