The height of the protective field H above the reference plane and the resolution d of the
AOPD are related to each other as follows:
The safety distance S for safeguarding danger areas is derived in accordance with EN
999 from the formula:
Hmin [mm] = 15 x (d -50) [mm] or d [mm] = H/15 + 50 [mm]
H = Height of the protective field above the reference plane, maximum 1000 mm
Heights equal to or less than 300 mm are considered too low for adults to crawl
under
d = Resolution of the AOPD
S [mm] = K [mm/s] x T [s] + C [mm]
S = Safety distance in mm
K = Approach speed of 1600 in mm/s.
T = Total time of the delay in seconds;
Total of:
the response time of the protective device t

a)
the response time of the safety interface, if any t
