Table 10: Size of the unprotected areas
Mounting with hard guards
Figure 26: Example of mounting with hard guards
² Fit the hard guard such Œ that the areas not covered by the safety laser
scanner are completely protected against personnel standing in them.
Mounting in a recess
Figure 27: Form of the recess
² Design the recess Œ to be sufficiently deep enough that it
completely covers the area not protected by the safety laser
scanner (Figure 26) and such that standing in an unscanned area
 is not possible.
4.2 Stationary Vertical Operation for Access
Protection
Access protection can be used when the access to the machine can be
defined by physical means. For access protection the SafeZone safety
laser scanner detects the entry of an entire body.
4.2.1 Safety distance
For access protection, a safety distance (S) must be maintained between
protective safety field and hazardous area. This safety distance ensures
that the hazardous point can only be reached after the dangerous state of
the machine has been completely stopped.

ATTENTION Prevent unprotected areas.
Mount the SafeZone safety laser
scanner such that there are no
unprotected areas. Take one of the
precautions given in the following:
² Install hard guards to prevent
standing behind.
² Install the SafeZone safety laser
scanner in a recess.
IMPORTANT Prevent crawling beneath the recess by
limiting the height of the recess such
that nobody can crawl beneath.
IMPORTANT To ensure adequate access protection,
a response time of ~ 90 ms and a
resolution of 150 mm or finer is
required.
To protect the SafeZone multizone
scanner against inadvertent
adjustment or manipulation, use the
contour of the surrounding area as a
reference (see Section 3.4.3 “Using the
contour of the protective safety field as
a reference” on page 12).
