  • Page 17: Minimum Installation Distance

    Instruction Manual SG2 EXTENDED 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 EXTENDED 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 EXTENDED It is thus important to perfectly align the safety light curtain according to the minimum distance from reflecting surfaces. The minimum distance depends on:  Working distance between emitter (TX) and receiver (RX) = operating distance ...
