    Instruction Manual Safety Light Curtain OY32 2.2.4. Emitter and receiver orientation The two units shall be assembled parallel each other, with the beams arranged at right an- gles with the emission and receiving surface, and with the connectors orientated towards the same direction.
  • Page 20 Instruction Manual Safety Light Curtain OY32 The operator must respect the following precautions when using the deviating mirrors: • The alignment of the emitter and the receiver can be a very critical operation when deviating mirrors are used. Even very small displacement of the mirror is enough to lose alignment. The use of laser pointer accessory is recommended under these conditions.

  • Page 21: Controls After First Installation

    Instruction Manual Safety Light Curtain OY32 2.2.6.

  • Page 22: Mechanical Mounting

    Two types of brackets can be used to fix the two units. Angled fixing brackets Angled fixing brackets are supplied with all OY32 models (Fig.15). Adjustable supports for correcting unit inclination on the axes are available on request (see section 14 “Accessories”).
  • Page 23 Instruction Manual Safety Light Curtain OY32 In case of applications with particularly strong vibrations, vibration dampers together with mounting brackets are recommended to reduce the impact of the vibrations. Fig. 17 The recommended mounting positions according to the light curtain length are shown in Fig.18 and in the following table.

  • Page 24: Electrical Connections

    Instruction Manual Safety Light Curtain OY32 ELECTRICAL CONNECTIONS All electrical connections to the emitting and receiving units are made through a male M12 connector, located on the lower part of the two units. For receiver a M12 8-pole connector is used, while for emitter a M12 4-pole connector is used.

  • Page 25: Notes On Connections

    4.1. Notes on connections For the correct functioning of the OY32 safety light curtains, the following precautions re- garding the electrical connections have to be respected. • Do not place connection cables in contact with or near high-voltage cables and/or cable undergoing high current variations (e.g.
  • Page 26 Instruction Manual Safety Light Curtain OY32 • If one of these configurations is erroneously used, the device enters into the output failure condition (see section 7 “Diagnostic functions”). • Connect both OSSDs to the activating device. Failure to connect an OSSD to the activating device jeopardises the system safety degree that the light curtain has to control.

  • Page 27: Ground Connection

    Safety Light Curtain OY32 Ground Connection OY32 safety light curtain units are preset for easy ground connection. A special compart- ment, positioned onto caps and marked with the special symbol shown in Figure 24, allows connection with ground cable by means of an additional screw coming with the equipment.
