6.3 - Detection zone parallel to the direction of approach

When the direction of approach is parallel to the detection zone, the minimum distance, S, shall be calculated using Equation:

                                                                                                                             S=(K×T)+C

Where

K: 1600 mm/s

C: 1200 mm – 0,4H, but non less than 850 mm, where H is the height of the detection zone above the reference plane.

The lowest allowable height of the detection zone shall be calculated using Equation:

                                                                                                                             H=15(d-50)

If f is less than 50, H shall never be less than 0.

For a given height of the detection zone, the corresponding sensor detection capability, s, shall be calculated using Equation:

                                                                                                                             d=(H/15)+50
