Dangerous area calculation
6.3.1
Introduction
The dangerous area of the machinery to which safeRS3 is applied must be calculated
as indicated in standards ISO 13855:2010. For safeRS3 the fundamental factors for
calculation are height (h) and inclination (α) of the sensor (see
).
6.3.2
Formula
To calculate the depth of the dangerous area (S), use the following formula:
