4.4 Installation Specifications for COMPACT Light Grids for Danger Area Safe-
guard, Horizontal Arrangement (Series C50 and C90)
When light grids, horizontal arrangement are being mounted to safeguard danger areas, make sure
that the height of the sensing field does not exceed 1000 mm above the ground. If H exceeds 300
mm (200 mm if children are present), an undetected approach underneath the sensing field is pos-
sible. This must be taken into account when the risk is assessed. The lowest admissible height for
grid assembly depends on the AOPDs resolution, to ensure that the human leg or foot can be
recognized without failure. The minimum safety distance is calculated as follows:
S = (1.6 mm/ms x T) + C
C = 1200 mm - 0.4 x H
(with H = height of the sensing field above reference plane C
Assembly height:
H = 1000 mm
max
H = 15 (d - 50 mm) with d = resolution of the AOPD
min
The admissible height for grid assemblies of the COMPACT light grids by using this calculation is:
