For this purpose, the safety laser scanner scans the visible surrounding contour several
t
imes. Based on the data obtained, the Safety Designer suggests the contour and size
of the field.
You can use the Su
ggest field tool to create a field.
Important information
NOTE
If y
ou propose a protective field, the proposal does not replace calculation of the
minimum distance. You must calculate the minimum distance and check whether the
size of the proposed protective field is sufficient. You must also take into account the
measurement tolerances of the safety laser scanner.
Existing field geometries
•
D
elete existing shapes: The field is redrawn according to the surrounding contour.
•
Refine existing shapes: The existing field is adapted to the surrounding contour.
Measurement method
•
Use e
very single distance value: Each scan of the surrounding contour is used individu‐
ally to draw the field.
•
Use median of distance values: The median of the last 25scans is used to draw the
field.
Type of teach-in
•
Onl
y allow reduction: The shortest measured distance is used at each angle. If you
walk along the borders of the imaginary field and, e.g., hold a board or cardboard
into the laser beam, this restricts the surrounding contour.
•
Allow expansion: The surrounding contour is used as it is measured.
Automatic reduction
Y
ou can specify that the proposed field is drawn smaller than the measured surround‐
ing contour so that the field will be at a distance from walls. The default value corre‐
sponds to the TZ value (tolerance zone of the safety laser scanner).
Smoothing by point reduction
T
he proposed contour may initially be uneven and consist of very many points. With the
Smoothing by point reduction option, you can reduce the number of points and simplify the
lines.
