EOS2 SAFETY LIGHT CURTAINPRINCIPLE OF OPERATIONIf the protected area is clear, the two outputs on the Receiver are active andenable the machine to which they are connected to operate normally.Each time that an object bigger than or equal in size to the resolution of thesystem intercepts the optical path of one or more beams, the Receiver deactivatesits own outputs.This condition enables dangerous machine movements to be stopped (by meansof an adequate machine emergency stop circuit).Î Resolution is the smallest sized object that, passing through the protected area,interrupts at least one of the beams generated by the light curtain (Figure 1),causing certain intervention of the device and consequent stopping of thedangerous movement of the machine.Figure 1 - ResolutionP = Pitch between two lensesD = Diameter of a lensR = Resolution = P+DPRDReceiverEmitterBeamResolution remains constant regardless of working conditions as it depends only on thegeometric characteristics of the mirrors and on the centre distance between two adjacentlenses.The height of the protected area is the effective height protected by the safety lightcurtain. If the curtain is positioned horizontally, this value indicates the depth of theprotected area.The working range indicates how far the emitter and receiver can be separated andfunction properly.EOS2 is available with the following resolutions:• 30mm (protected heights from 150mm to 1500mm): PROTECTION OF THE HANDS.• 40mm (protected heights from 300mm to 1500mm): PROTECTION OF THE HANDS.• 50mm and 90mm (protected heights from 300mm to 1800mm):PROTECTION OF THE LIMBS.English The EOS2 is also available in a Multibeam version with a distance between themirrors of:• 500mm (2 beams), 400mm (3 beams), 300mm (4 beams).PROTECTION OF THE BODY.4 8540738 • 2nd December 2009 • Rev.2
