Ä Define the limits of the protective field using the safety distance S without an additional distance.
Ä Determine the biggest protective field radius R
G
for this protective field.
The biggest protective field radius determines the additional distanceZ
SM
for the system-related mea-
surement error, by which the protective field contour must be enlarged.
The position of the rotary mirror's center point with regard to the housing is provided by the dimen-
sioned drawings.

Ä Avoid retro-reflectors at the beam level beyond the protective field boundaries. If this is not possible,
add another additional distanceZ

of 100mm.
Minimum distanceD to the protective field contour
The minimum distanceD is the distance between point of operation and protective field contour.
D [mm] = Minimum distance between the point of operation and the protective field contour

[mm] = Additional distance for system-related measurement error

[mm] = Additional distance for retro-reflectors
Ä If the protective field runs up against fixed boundaries, such as walls or machine frames, take a coun-
tersinking into the machine contour of at least the size of the necessary additional distance Z
SM
, and
Z
REFL
where required, into account. With the protective field contour under these conditions, stay about
50mm away from the machine surface.
Ä If the protective field runs up against hard guards, ensure that the protective field ends under instead of
in front of the hard guards. The width of the lower post must correspond with the size of the required
additional distances.
Ä If all hazards in the fenced off area are covered by the safety sensor and the height of the beam level is
300mm, you can raise the bottom edge of the hard guards from 200 mm to 350 mm in the protective
field range. The protective field reaching to under the hard guards takes over the protective function of
preventing an adult from crawling under in this case.
NOTICE
The beam level of the safety sensor is level with the alphanumerical display.
Ä Prevent obstructions within the calculated protective field boundaries. If this is not possible, implement
protective measures so that the point of operation cannot be reached from out of the shadow of the ob-
struction.
