EOS2 SAFETY LIGHT CURTAINUse of deflecting mirrorsFor protection or control of areas accessible from several sides, one or more deflectingmirrors can be used in addition to the Emitter and Receiver.Deflecting mirrors make it possible to redirect the beams generated by the Emitter onseveral sides.Wishing to deflect the beams generated by the Emitter by 90°, the perpendicular to thesurface of the mirrors must form an angle of 45° with the direction of the beams.An application in which two deflecting mirrors have been used for "U" shaped protectionis illustrated in the figure below.Figure 7 – Deflecting mirrorsWhen using deflecting mirrors, comply with the following rules:• Position the mirrors so as to comply with the minimum safety distance S(Figure 7) on each side of access to the dangerous area.• The working distance (working range) is given by the sum of the lengths of all theaccess sides to the protected area. (Note that the maximum working rangebetween the Emitter and Receiver is reduced by 15% for each mirror used).• In the installation phase, take care to avoid twisting along the longitudinal axis ofthe mirror.• Standing close to and in axis the Receiver, check that the entire shape of theEmitter is visible on the first mirror.• It is advisable not to use more than three deflecting mirrors.English10 8540738 • 2nd December 2009 • Rev.2
