Page 5: Principle Of Operation
EOS2 SAFETY LIGHT CURTAIN PRINCIPLE OF OPERATION If the protected area is clear, the two outputs on the Receiver are active and enable 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 the system intercepts the optical path of one or more beams, the Receiver deactivates its own outputs. -
Page 6: Installation
EOS2 SAFETY LIGHT CURTAIN INSTALLATION Before installing the EOS2 safety system, check all the conditions listed below: The level of protection of EOS2 (Type 2, SIL2, SILCL2, PLd) must be compatible with the level of danger of the system to be protected. The safety system is used only as a stopping device and not to control the machine. -
Page 7: Positioning
EOS2 SAFETY LIGHT CURTAIN Positioning The Emitter EOS2E and the Receiver EOS2R must be positioned so that it is impossible to access the dangerous area from above, from below and from the sides without intercepting one of the beams. Useful indications for correct positioning of the light curtain are provided in the figure below. -
Page 8: Master/Slave Positioning
EOS2 SAFETY LIGHT CURTAIN Master/Slave Positioning In addition to standard models (that can be positioned either horizontally or vertically), EOS2 can be purchased in a MASTER/SLAVE configuration. This configuration comprises two (or three) pairs of light curtains in which the two (or three) Emitters and the two (or three) Receivers are connected in series. -
Page 9: Calculation Of Safety Distance
EOS2 SAFETY LIGHT CURTAIN Calculation of safety distance The light curtain must be positioned at a distance equal to or greater than the minimum safety distance S so that the dangerous point can be reached only after stopping the dangerous movement of the machine (Figure 5). According to the EN999:2008 European standards, the minimum safety distance S must be calculated using the following formula : S = K (t1 + t2) + C... -
Page 10: Multiple Systems
EOS2 SAFETY LIGHT CURTAIN Multiple systems When several EOS2 are used, precautions must be taken to prevent optical interference between these: position the elements so that the beam of the Emitter of one system is received only by its respective Receiver. Figure 6 provides examples of correct positioning of two photo-electric systems. -
Page 11: Use Of Deflecting Mirrors
EOS2 SAFETY LIGHT CURTAIN Use of deflecting mirrors For protection or control of areas accessible from several sides, one or more deflecting mirrors can be used in addition to the Emitter and Receiver. Deflecting mirrors make it possible to redirect the beams generated by the Emitter on several sides. -
Page 12: Distance From Reflective Surfaces
EOS2 SAFETY LIGHT CURTAIN Distance from reflective surfaces The presence of reflective surfaces close to the light curtain may cause occasional reflections that prevent sensing. Referring to Figure 8, object A is not detected due to surface S that, reflecting the beam, closes the optical path between the Emitter and Receiver. -
Page 13: Mechanical Assembly And Optical Alignment
EOS2 SAFETY LIGHT CURTAIN Mechanical assembly and optical alignment The Emitter and Receiver must be installed facing each other, at a distance equal to or less than that indicated in the technical data. Using the provided inserts and fastening brackets, place the Emitter and Receiver so that they are aligned and parallel to each other, and with the connectors facing the same side. -

EOS2 SAFETY LIGHT CURTAIN Electrical connections WARNINGS Before making electrical connections, make sure that the mains voltage matches the one indicated in the technical data. The Emitter and Receiver must be powered at a 24Vdc±20% (PELV, in compliance with the standard EN 60204-1 (Chapter 6.4)). The electrical connections must be made according to the wiring diagrams provided in this manual. -

Page 28: Checkouts And Maintenance
EOS2 SAFETY LIGHT CURTAIN Figure 26 - FIE inserts and LE fastening brackets (provided) CHECKOUTS AND MAINTENANCE Checking of light curtain efficiency Before each shift or at power-on, check the correct operation of the light curtain. To do this, comply with the following procedure which uses a test object (available free of charge on request as accessory) to intercept the beams. - Page 29 EOS2 SAFETY LIGHT CURTAIN Never use abrasive or corrosive products, solvents or alcohol that could damage the part to be cleaned or wool cloths in order to prevent electrifying the front surface. Even very fine scratching of the front plastic surfaces may increase the width of the beam emitted by the light curtain, thereby impairing its efficiency in the presence of reflecting side surfaces.
