You can specify for each warning output whether activation is to occur when a Low signal
or a High signal is present.
5.1.2 Series connection
The series connection of safety laser scanners means using several safety laser scanners
in a configuration (safety laser scanner arrangement). The OSSDs are in the controlling
master unit that is connected to an 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.
