- Page 6 INSTALLATION Before installing the EOS4 safety system, check all the conditions listed below: The level of protection of EOS4 (Type 4, SIL3, SILCL3 PLe) must be compatible with the level of danger of the system to be protected. ...
-
Page 7: Positioning
EOS4 SAFETY LIGHT CURTAIN Positioning The Emitter EOS4E and the Receiver EOS4R 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
In addition to standard models (that can be positioned either horizontally or vertically), EOS4 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
EOS4 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 so that the dangerous point can be reached only after stopping the dangerous movement of the machine (Figure 5). -
Page 10: Multiple Systems
EOS4 SAFETY LIGHT CURTAIN Multiple systems When several EOS4 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. -
Page 11: Use Of Deflecting Mirrors
EOS4 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
EOS4 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 is not detected due to surface that, reflecting the beam, closes the optical path between the Emitter and Receiver. -
Page 13: Mechanical Assembly And Optical Alignment
EOS4 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 , place the Emitter and Receiver so that they are aligned and parallel to each other, and with the connectors facing the same side. -

Page 20: Configuration And Operating Modes (Master Models / With Integrated Control Functions)
Automatic operation If the EOS4 light curtain is used in AUTOMATIC mode, it will not be equipped with a start/restart interlock circuit. In most applications, this safety function is compulsory. Carefully assess the risks analysis of your own application. -
Page 21: Connection Of External Contactors K1 And K2
EOS4 SAFETY LIGHT CURTAIN Connection of external contactors K1 and K2 In both operating modes, it is possible to activate control of the external contactors K1/K2 (series of contacts). If this control is to be used, it is necessary to connect pin 4 of the M12 8-pin connector of the Receiver with the power supply (24VDC) via a set of NC contacts (feedback) of the external contactors. -
