4.3.6.6 Height of the scan plane
Overview
T
ake into consideration both the minimum and maximum height of the scan plane. You
can use the fixing holes of the safe multibeam scanner as a reference for the scan
plane.
Minimum height
T
he safe multibeam scanner checks every protective or warning field using a vertical
aperture angle of up to 4°. Calculate the minimum height for the scan plane so that the
protective or warning field is not disturbed by the floor.
h
min
= 0.035 x L
max
+ 30 mm
where:
•
h
min
= minimum height in millimeters (mm)
•
L
max
= maximum length used for protective or warning fields in millimeters (mm)
Table 3: Example values for the minimum height
Maximum length used (mm) Minimum height (mm)
0 30
1000 65
2000 100
3000 135
4000 170
Maximum height
T
he scan plane must be at a maximum height of 200 mm everywhere. Otherwise,
persons lying horizontally may not be detected.
In many cases, a mounting height (height of the scan plane) of 150 mm above the floor
is suitable.
