Safety light curtains, parallel approach
S = 1600 * T + C
T is the sum of the reaction time of the AOPD, safety interface and the stopping time of the machine
C = 1200 - 0.4 * H; Cmin = 850 mm
H is the height of protective field above reference plane
Hmin =15 * (d - 50 mm); Hmax = 1000 mm;
Heights > 300 mm are considered to be possible for an adult to crawl under.
Calculation of the required d for a known height of the protective field:
d = H / 15 + 50 mm
d is the detection capability of the AOPD in mm.
50 ≤ d ≤ 116 mm
