3.2.6
Protective field, warning field and field set
The 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.
The 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 warning field must not be used for tasks relating to the protection of people.
Field set comprising a protective field and warning field(s)
Protective fields and warning fields form the so-called field set. These field sets are con‐
figured using the CDS. You can configure the fields to be radial, rectangular or free
form. When the area to be monitored changes, you can reconfigure the safety laser
scanner via the software without additional mounting work.
Depending on the I/O module used, you can define up to 32 field sets and save them in
the safety laser scanner. This allows you to switch to another field set if the monitoring
situation changes.
You can configure different field sets:
•
Field sets that comprise one protective field and one warning field
•
Field sets that comprise two protective fields
•
Field sets that comprise one protective field and two warning fields
