Series connection

The series connection of safety laser scanners means using several safety laser scanners
in a configuration. The OSSD are in the controlling master unit that is connected to the
evaluation device.
In a series connection, each of the connected safety laser scanners monitors the area that
is covered by the light beam emitted from the safety laser scanner.

[5] Warning zone
The safety zones and warning zones can be defined independently of each other for each
safety laser scanner.
When an object or a person intrudes into the warning zone or safety zone, the status of the
relevant safety laser scanner is changed, shown in the display and signalled to the master.
Depending on the violated zone, the master triggers the relevant configured actions.
