[5] Warning zone
[6] Additional protective equipment for securing the danger zone that is not covered
by the safety laser scanner
The area can be divided into a safety zone and a warning zone.
If an object or a person violates the safety zone, the OSSDs switch to an OFF state.
When at least one warning output was selected during the configuration of outputs, actions
can be triggered (e.g. switching on indicator light unit), when an object or a person enters
the warning zone.

Function description
Operating Manual PSEN sc ME 5.5 08-17
1005388-EN-01 | 16
You can specify for each warning output whether activation is to occur when a Low signal
or a High signal is present.
4.1.2 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.

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.

Function description
Operating Manual PSEN sc ME 5.5 08-17
1005388-EN-01 | 17
For a violated safety zone, the OSSDs switch to the OFF state, for a violated warning zone
an indicator light unit can be switched on, for example.

The safety laser scanner scans the area in front of an automated guided vehicle system to
prevent collisions. When an object or a person is detected, the safety laser scanner sends
a signal to the automated guided vehicle system.
}When the warning zone is violated, an alarm of the automated guided vehicle system can
be triggered. The person can leave the route or remove the object from the route.
}When the protective zone is violated, a stop of the automated guided vehicle is triggered.
}The size of the protective zone is calculated from the hazard source, not from the dis-
tance to the safety laser scanner.
4.3 Reference outline monitoring
For vertical applications, national and international standards recommend monitoring a ref-
erence outline.
The reference outline is configured during the first installation of PSEN sc ME 5.5 08-17.
The distances measured during configuration are used as reference values for monitoring
the reference outline.
4.4 Use of zone sets and switching of zone sets
A zone set must include a safety zone and it can include a max. of two warning zones.
Each zone can include any number of geometrical shapes.
Each machine state can be assigned a signal at the control inputs or a combination of sig-
nals at the control inputs. Each of these assignments is assigned a zone set. The zone set
is always active whose control input signal/combination of signals is present.
