Protective safety field suggested by the safety laser scanner
You can also have the SCD software suggest a protective safety field. The
safety laser scanner scans the visible room contour several times. During this
process possible measurement errors are taken into account. From the data
obtained in this way the SCD software determines the contour of the
protective safety field.
Figure 14: Reading protective safety field and warning field
In those places at which the room contour is smaller than the nominal
scanning range (e.g. at
Œ), the protective safety field corresponds to the
room contour (less the measurement tolerances). In those places where
the room contour is larger than the nominal scanning range
, the
protective safety field corresponds to the nominal scanning range (4 or
5 m).
3.4.2 Application
• Possible resolution for stationary applications:
30 mm (hand detection with smaller safety distance)
- 40 mm (hand detection with larger safety distance)
- 50 mm (leg detection with smaller protective safety field
size)
- 70 mm (leg detection with larger protective safety field
size)
- 150 mm (body detection)
• Possible resolution for mobile application:
- 70 mm (leg detection)
ATTENTION Check the protective safety field
configuration.
Prior to commissioning the machine or
vehicle, check the configuration of the
protective safety fields using the
instructions in Section 8
“Commissioning” (page 36) and using
the checklist (page 54).
You can obtain the suggestion for the protective
safety field in the field set editor in the SCD
software: Device symbol SafeZone safety laser
scanner, command Edit field sets.... In the field set
editor window that opens, Suggest protective safety
field button.
The size determined for the protective safety field is:
• As large as the visible room contour.
• In those places where there is no room contour
within the scanning range, as large as the
maximum scanning range of the safety laser
scanner (4 or 5 m).
IMPORTANT The measurement error tolerances of
the SafeZone safety laser scanner are
automatically subtracted from the
protective safety field suggested. As a
result the protective safety field is
slightly smaller than the surface
acquired.

WARNING Check the protective safety field
suggested.
The scanner cannot calculate the safety
distance necessary for your
application. Calculate the safety
distance based on the description in
Section 4 “Installation and mounting”
on page 18. Prior to commissioning the
machine or vehicle, check the
configuration of the protective safety
fields using the instructions in Section
8 “Commissioning” on page 36 and
using the checklist on page 54.
With the SCD software you can configure the
SafeZone safety laser scanner for the required
application. For each application you first set the
resolution (device symbol SafeZone safety laser
scanner system, context menu Configuration draft,
Edit..., file card Application):
IMPORTANT For mobile applications a resolution of
only 70 mm is required for leg
detection, as a lower resolution is
sufficient for the detection of a human
leg due to the movement of the
vehicle.
