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 Value
Measurement
unit
K Maximum dangerous area access
speed
1600 mm/s
T Total system stopping time (SBV
System Series + machinery)
0.1 + Machinery stopping time (calculated in
accordance with ISO 13855:2010 standard)
s
C Corrective constant according to
standard ISO 13855:2010
850 mm
Example 1
l Machinery stopping time =0.5 s
T = 0.1 s + 0.5 s = 0.6 s
S =1600 * 0.6 + 850 = 1810 mm
