The following table shows the formulae for calculating the safety distance S:20Perpendicularapproachß = 90˚ (± 5˚) S = 2000T + 8 * (d – 14) NB. To prevent bypassing thed = ≤ 40 mm where S > 100 mm AOPD, use EN 294. In practice,this standard is not alwaysapplicable because it regardsthe hand as a deformableelement. In this case it isnecessary to seek the adviceof an accident prevention body.where S > 500 mmtake S = 1600T + 8 * (d – 14).In this case S cannot be< 500 mm.40 < d ≤ 70 mm S = 1600T + 850 Height of lowest beam ≤ 300 mmHeight of highest beam ≥ 900 mmd > 70 mm No. of Recommendedmulti-beam S = 1600T + 850 Beams heights4 300, 600, 900, 1200 mm3 300, 700, 1100 mm2 400, 900 mmsingle beam S = 1600T + 1200 1 750 mmParallel S = 1600T + (1200 – 0.4 * H) 15 * (d – 50) ≤ H ≤ 1000 mm.approach where 1200 – 0.4 * H > 850 mm Where H ≥ 300 mm there is arisk of undetected access underß = 0˚ (± 5˚)the beam to be taken into accountfor H where d ≤ H/15 + 50Angular Where ß > 30 ˚C, cf. d ≤ H/15 + 50 applies to theapproach perpendicular approach; lowest beam.Where ß < 30 ˚C, cf. parallel5˚ < ß < 85˚ approach;S then applies to the furthestbeam whose height ≤ 1000 mmS: Minimum distance H: Height d: Resolutionß: Angle between plane of detection and direction of penetration T: TimeFig. 22: Formulae for calculating the safety distance115Machinery ProtectionDevices
