Protective field or warning field suggested by the safety laser scanner
The SCD software can suggest the protective field or warning field in the field set editor. The safety laser scanner scans the
visible surrounding contour several times. From the data obtained the SCD software suggests the contour and size of the
field. The following figure shows an example for the reading of a protective field:
Fig. 11: Reading the protective field
In those places at which the surrounding contour is smaller than the maximum protective field range (e.g. at ), the
protective field corresponds to the surrounding contour.
Note The measuring error tolerances for the SafeZone Mini are automatically subtracted from the protective field size. As a
result the protective field is slightly smaller than the surface covered
.
In those places where the surrounding contour is larger than the protective field range
, the protective field corresponds
to the possible scanning range.
Check the protective field suggested by the SCD software
The protective field suggested by the SCD software is not a replacement for the calculation of the minimum distance.
Calculate the minimum distance and check the effectiveness of the protective fields prior to commissioning the
application!
Pay attention to the descriptions in Chapter 5, “Mounting” on page 24, the notes in Chapter 9, “Commissioning” on page
47 and the “Checklist” on page 70.
Using the contour as a reference
In addition to the protective field, the SafeZone Mini can also monitor a contour (e.g. the floor in vertical applications).

contour as reference
For contour monitoring you define a contour segment . The contour segment comprises a positive  and a negative 
tolerance band.
