  • Page 7: How To Choose The Device

    Instruction Manual SG2 BASE 1.3. 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: 1.3.1. Resolution The resolution of the device is the minimum dimension that an opaque object must have in order to obscure at least one of the beams that constitute the sensitive area.

  • Page 8: Controlled Height

    SG2 BASE Instruction Manual 1.3.2. Controlled height The controlled height is the height protected by the safety light curtain ( Hp ) Fig. 2 The SG2-B controlled height is delimited by the yellow line pad-printed on the front glass and by the dimensions listed in the table: Controlled height Hp Model...

  • Page 9: Minimum Installation Distance

    Instruction Manual SG2 BASE 1.3.3. Minimum installation distance The safety device must be positioned at a specific safety distance (Fig. 3). This distance must ensure that the dangerous area cannot be reached before the dangerous motion of the machine has been stopped by the ESPE.
  • Page 10 SG2 BASE Instruction Manual 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). If the safety light curtain must be mounted in a horizontal position (Fig.4), the distance between the dangerous area and the most distant optical beam must be equal to the value calculated using the following formula:...
  • Page 11 Instruction Manual SG2 BASE Practical examples: Let's suppose to have a light curtain with height = 600 mm 1) To calculate the distance of the device from the ESPE, in a vertical position, the following formula is used: S = K*T + C where: T = t = ESPE response time + SE-SR2 relay release time (max 80 ms)

  • Page 12: Typical Applications

    - Automatic and semiautomatic assembly lines; - Automatic warehouses. In food industry applications, DATALOGIC AUTOMATION Technical Service has to verify the compatibility of the material of the safety light curtain housing with any chemical agents used in the production process.
  • Page 13 Instruction Manual SG2 BASE Example 2: Cooling and conditioning systems Cooling and conditioning systems, as well as automotive equipment and components are checked inside a machine, to detect possible leaks by a helium mass spectrometer. The point where these parts are positioned inside the measuring chamber requires a Type 2 protection ensuring a certain space saving and an easy access to the protected area.

  • Page 14: Safety Information

    SG2 BASE Instruction Manual 1.5. Safety information For a correct and safe use of the safety light curtains of the SG2 series, 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 par.

  • Page 15: Installation Mode

     The presence of intense electromagnetic disturbances could affect device correct operation. This condition shall be carefully assessed by seeking the advice of DATALOGIC AUTOMATION Technical service.  The operating distance of the device can be reduced in presence of smog, fog or airborne dust.

  • Page 16: General Information On Device Positioning

    SG2 BASE Instruction Manual 2.2. General information on device positioning The safety light curtain should be carefully positioned, in order to reach a very high protection standard. Access to the dangerous area must only be possible by passing through the protecting safety light beams.

  • Page 17: Minimum Installation Distance

    Instruction Manual SG2 BASE When the installation of the safety light curtain very near to the dangerous area is not possible, a second light curtain must be mounted in a horizontal position in order to prevent any lateral access (as shown in Fig.6b).

  • Page 18: Minimum Distance From Reflecting Surfaces

    SG2 BASE Instruction Manual 2.2.2. 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 compromise the recognition of an object inside the controlled area.
  • Page 19 Instruction Manual SG2 BASE It is thus important to position the safety light curtain according to the minimum distance from reflecting surfaces. The minimum distance depends on:  Operating distance between emitter (TX) and receiver (RX);  Real opening angle of ESPE (EAA); in particular: for ESPE type 2 EAA = 10°...

  • Page 31: Alignment Procedure

    Instruction Manual SG2 BASE ALIGNMENT PROCEDURE The alignment between the emitting and the receiving units is necessary to obtain the correct functioning of the light curtain. A good alignment prevents outputs instability caused by dust or vibrations. The alignment is perfect if the optical axes of the first and the last emitting unit’s beams coincide with the optical axes of the corresponding elements of the receiving unit.
  • Page 32 SG2 BASE Instruction Manual The standard installation described hereinafter is the one shown in Fig. 22, i.e. with the bar assembled with the connectors pointing down. Two yellow LEDs ( LAST, SYNC) on SG2 receiver, facilitates the alignment procedure. During standard operation, the LEDs indicate the safety light curtain status, as shown in the table.

  • Page 33: Correct Alignment Procedure

    Instruction Manual SG2 BASE 5.1. Correct alignment procedure The light curtain alignment can be effected only after having completed the mechanical installation and the electrical connections.

    SG2 BASE Instruction Manual 15. GLOSSARY ACTIVE OPTOELECTRONIC PROTECTIVE DEVICE (AOPD): its detection function is achieved thanks to the use of optoelectronic receivers and emitters detecting the optical beams interruptions inside the device caused by an opaque object present inside the specified detecting area. An active optoelectronic protective device (AOPD) can operate both in emitter-receiver mode and in retro-reflective light curtains.
  • Page 53 Instruction Manual SG2 BASE OUTPUT SIGNAL SWITCHING DEVICE (OSSD): part of the electrosensitive protective equipment (ESPE) connected to machine control system that, when the sensor is triggered during standard operating mode, is switched to the inactive status. PROTECTED AREA: area where a specified test object is detected by the ESPE.
