  • Page 3: Introduction

    EOS4 SAFETY LIGHT CURTAIN INTRODUCTION The EOS4 light curtain is an optoelectronic safety device belonging to the category of Type 4 electro-sensitive protective equipment for the protection of personnel exposed to risks inherent in the use of hazardous machines or plants, complying with the IEC 61496-1,2 and EN 61496-1 standards.
  • Page 4: Principle Of Operation

    • 50mm and 90mm (protected heights from 300mm to 1800mm): PROTECTION OF THE LIMBS. The EOS4 is also available in a Multibeam version with a distance between the mirrors of: • 500mm (2 beams), 400mm (3 beams), 300mm (4 beams).
  • Page 5: Installation

    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. The safety system is used only as a stopping device and not to control the machine.
  • Page 6: 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 7: 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 8: 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 S so that the dangerous point can be reached only after stopping the dangerous movement of the machine (Figure 5).
  • Page 9: 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 10: 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 11: 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 A is not detected due to surface S that, reflecting the beam, closes the optical path between the Emitter and Receiver.
  • Page 12: 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 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.

    Table 12 –Setting of manual/automatic mode 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 20: 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. 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.

    FAIL condition (Table 18) RED BLINKING Table 15 – RX light signals EOS4 (With integrated control functions) The type of fault is identified by the number of flashes (see Troubleshooting chapter) Double blinking (at power-on) of the GREEN led indicates that high range has been selected.
  • Page 23: Test Function

    The minimum duration of the TEST command must be at least 4 msec. Status of the outputs On the Receiver of the EOS4 there are two PNP static outputs whose status depends on the condition of the protected area. The maximum permissible load for each output is 400mA @ 24VDC, corresponding to a resistive load of 60Ω.

    ON. Figure 27 – Efficiency check The EOS4 light curtain does not require any specific maintenance; however, it is good practice to clean the front protective surfaces of the mirrors of the Emitter and Receiver. Clean with a damp cloth; in very dusty environments, after cleaning the front surface, spray with an anti-stat product.
