3.2.4 Protective field, warning field and field set
Protective field
T
he protective field protects the hazardous area of a machine or vehicle. As soon as the
safety laser scanner recognizes an object in the protective field, the device switches the
OSSDs to the OFF state thereby causing the machine to be switched off or the vehicle
to be stopped.
If 2 protective fields have been configured, the two cut-off paths must be routed to inde‐
pendent OSSD pairs of the Flexi Soft safety controller.
Warning field
T
he warning fields can be defined so that the safety laser scanner detects an object
even before the actual hazardous area.
Warning field 1 can be used in particular for vehicle protection applications to detect an
object before the actual hazardous area and to slowly retard the movement of the vehi‐
cle or bring it to a standstill. This can reduce the wear on the brakes of the AGV. Warn‐
ing field 2 can also be used to trigger a warning signal.
NOTE
A w
arning field must not be used for tasks relating to the protection of people.
