5.4.8.4 Sample calculation of a maximum range of a detection zone
The formulas:
S
BDIFF
= G
BDIFF
+ S + Z
SM
yield, under consideration of the width of the danger zone results in the maximum
distance to be monitored:
S
BDIFF
= 700 mm + 2248 mm + 83 mm = 3031 mm
S
MAX
= 3901 mm
5.4.8.5 Sample calculation of an undercut
This example is based on the following application data. If the scanner is mounted
across from the machine (see Fig. 5.4-4), the undercut dimension can be reduced by
d
= 70 mm.
The formula
Z
UMIN
= Z + 83 mm – d
results in a minimum undercut:
Z
UMIN
= 83 mm + 83 mm – 70 mm = 96 mm
It is not allowed for a person to be able to step beneath the undercut.
