  • Page 6: General Information

    SG4 BASE 1 GENERAL INFORMATION 1.1 GENERAL DESCRIPTION The safety light curtains are optoelectronic multibeam devices that are used to protect working areas that, in presence of machines, robots, and automatic systems in general, can become dangerous for operators that can get in touch, even accidentally, with moving parts.

  • Page 7: Package Contents

    SG4 BASE Some parts or sections of this manual containing important information for the user or installing operator are preceded by a note: Notes and detailed descriptions about particular characteristics of the safety devices in order to better explain their functioning. Special instructions regarding the installation process.

  • Page 8: New Features Compared To Se4-Plus (Edm)

    SG4 BASE 1.3 NEW FEATURES COMPARED TO SE4-PLUS (EDM) With respect to SE4-PLUS (EDM) series, the SG4 BASE safety light curtain series presents new important features: • Higher operating distance • Shorter response time (see cfr.TECHNICAL DATA page 48) •...

  • Page 9: How To Choose The Device

    SG4 BASE 1.4 HOW TO CHOOSE THE DEVICE There are at least three different main characteristics that should be considered when choosing a safety light curtain, after having evaluated the risk assessment. 1.4.1 Detection capability The detection capability (or resolution) of the device is the minimum diameter that an opaque object must have in order to obscure at least one of the beams that constitute the detection zone and to actuate the sensing device.

  • Page 10: Height Of The Detection Zone

    SG4 BASE 1.4.2 Height of the detection zone The controlled height is the height protected by the safety light curtain.

  • Page 11: Minimum Installation Distance

    SG4 BASE 1.4.3 Minimum installation distance The safety device must be positioned at a specific safety distance (Fig 3 - page 11). This distance must ensure that the dangerous area cannot be reached before the dangerous motion of the machine has been stopped by the Safety Control System.
  • Page 12 SG4 BASE When devices with > 40 mm resolution are used, the height of the top beam has to be ≥ 900 mm (H2) from machine supporting base while the height of the bottom beam has to be ≤ 300 mm (H1).

  • Page 13: Typical Applications

    SG4 BASE 1.5 TYPICAL APPLICATIONS Example 1: Operating point protection on drilling machines The operator positions the part and takes it back after machining. The operator must be protected against possible abrasions while working. Solution: SG 14mm safety light curtain is especially suitable for this kind of application, which requires the installation of the device directly on the machine.
  • Page 14 SG4 BASE Example 3: Paper cutting machines These machines typically cut paper to a specific size for newspapers or special applications. The operator must be protected against abrasion or cuts by cutter blades. Solution: SG 30mm safety light curtain is especially suitable for this kind of application, which require the installation of the device directly on the machine.

  • Page 15: Safety Information

    SG4 BASE 1.6 SAFETY INFORMATION For a correct and safe use of the safety light curtains, the following points must be observed: • The stopping system of the machine must be electrically controlled. • This control system must be able to stop the dangerous movement of the machine within the total machine stopping time T as per paragraph Minimum installation distance page 11 and during all working cycle phases.

  • Page 16: Installation

    SG4 BASE 2 INSTALLATION 2.1 PRECAUTIONS TO BE OBSERVED FOR THE CHOICE AND INSTALLATION Make sure that the protection level assured by the light curtain device is compatible with the real danger level of the machine to be controlled, according to EN ISO 13849-1: 2015 or EN 62061:2005/A2: 2015.

  • Page 17: General Information On Device Positioning

    SG4 BASE 2.2 GENERAL INFORMATION ON DEVICE POSITIONING The safety light curtain should be carefully positioned in order to provide the necessary protection. Access to the dangerous area must only be possible by passing through the protecting safety light beams.

  • Page 18: Minimum Distance From Reflecting Surfaces

    SG4 BASE 2.2.1 Minimum distance from reflecting surfaces Reflecting surfaces placed near the light beams of the safety device (over, under or laterally) can cause passive reflections. These reflections can affect the recognition of an object inside the controlled area. Moreover, if the RX receiver detects a secondary beam (reflected by the side-reflecting surface) the object might not be detected, even if the object interrupts the main beam.

  • Page 23: Use Of Deviating Mirrors

    SG4 BASE 2.2.4 Use of deviating mirrors The control of any dangerous area, with several but adjacent access sides, is possible using only one safety device and well-positioned deviating mirrors. The figure shows a possible solution to control two different access sides, using one mirror placed at 45° with respect to the beams.

  • Page 24: Controls After First Installation

    SG4 BASE 2.2.5 Controls after first installation The control operations to carry-out after the first installation and before machine start-up are listed hereinafter. The controls must be carried-out by qualified personnel, either directly or under the strict supervision of the person in charge of machinery Safety.

  • Page 25: Mechanical Mounting

    SG4 BASE 3 MECHANICAL MOUNTING The emitting (TX) and receiving (RX) units must be installed with the relevant sensitive surfaces facing each other. The connectors must be positioned on the same side and the distance must be included within the operating range of the model used (see cfr.TECHNICAL DATA page 48).
  • Page 26 SG4 BASE Anti-vibration shock absorbers together with fixing brackets are recommended in applications with particularly strong vibrations to reduce the impact of the vibrations.
