5.3 Dangerous area calculation

5.3.1 Introduction
The dangerous area of the machinery to which SBV System Series is applied must be calculated as indicated in
standards ISO 13855:2010. For SBV System Series the fundamental factors for calculation are height (h) and
inclination (α) of the sensor, see "Sensor position" on page 42.
5.3.2 Formula
To calculate the depth of the dangerous area (S), use the following formula:
Where:
Variable Description
K Maximum dangerous area access
speed
T
Total system stopping time (SBV
System Series + machinery)
C
Corrective constant according to
standard ISO 13855:2010
Example 1
Machinery stopping time = 0.5 s
l
T = 0.1 s + 0.5 s = 0.6 s
S = 1600 * 0.6 + 850 = 1810 mm
