5.1.3 Safety distance and beam heights for access guarding
Determination of the beam heights and calculation of the safety distance of Safety Light
Curtains with a resolution of 20, 30 or 40
mm for use as access guarding, for example with
limited space between the protective field and a danger point.
Warning!
Please consider the additional safety instructions for access guarding with SOLID-2 in
Chapter 2.5.
Beam heights with use of Safety Light Curtain to guard access in accordance with
EN 999 and EN ISO 13857:
a = Safety distance (protective field/danger
point),
b = Height of the lowest beam above reference
plane, see Table 5.1-1
c = Height of the highest beam, see Table 5.1-1
d = Measures to prevent access from the sides
