EOS2 SAFETY LIGHT CURTAINVertical positioning of the light curtainModels with 30, 40mm resolutionEnglish These models are suitable for hand detection.The minimum safety distance S is calculated accordingto the following formula:S = 2000 (t1 + t2) + 8(D-14)(D=resolution)This formula is valid for distances S between 100 and500 mm. If, according to the calculation, S exceeds500 mm, the distance can be reduced down to aminimum of 500 mm using the following formula:S = 1600 (t1 + t2) + 8(D-14)If, in view of the particular configuration of themachine, the dangerous zone can be reached fromabove, the highest beam of the light curtain must be ata height H (from resting surface G) whose value isdetermined by using the ISO 13855 Standard.GFigure 12 -Vertical positioning30mm, 40mmpoint ofdanLight curtaingerdirectionofapproachreference planeModels with 50, 90mm resolution These models are suitable for detecting the armor the leg and must not be used to detectfingers or hands.The minimum safety distance S is determinedaccording to the following formula:S = 1600 (t1 + t2) + 850Î In every case the height H of the highest beamfrom resting surface G must not be smallerthan 900 mm, while the height of the lowestbeam P must not be bigger than 300 mm (ISO13855 Standard).
