Safety light curtains; Parallel Approach

S = 1600 * T + C

T is the total of response time of the AOPD, safety interface and the stop time of the machine.

C = 1200 - 0,4 * H; C_min = 850 mm

H is the Height of the protected field above ref. plane;
H_min =15 * (d - 50 mm); H_max = 1000 mm;
Height > 300 mm there is a risk of crawling beneath!

To calculate the required d when the height of the protected field is known:
d = H / 15 + 50 mm

d is the detection capability of the AOPD in mm.

Condition:
50 ≤ d ≤ 116 mm

A period must be entered to mark the decimal point.
