To add biasing, power off the FX30E/FX60E and remove the necessary assemblies (such as metal shield) to access the base board jumper pins located behind the RS-485 port. Then reposition the two shorting blocks on these jumper pins and reassemble the unit by remounting the processor module, hex standoffs, metal shield, and shield screws.

  • Risk of Electric Shock
  • Disconnect the power supply before making electrical connections. Contact with components carrying hazardous voltage can cause electric shock and may result in personal injury or death.
  • Avertissement
  • Risque de décharge électrique. Débrancher l'alimentation avant de réaliser tout branchement électrique. Tout contact avec des composants conducteurs de tensions dangereuses risque d'entraîner une décharge électrique et de provoquer des blessures graves, voire mortelles.

If the controller is already installed or mounted, we recommend that you remove the controller first. Then work on a flat, stable, well lit work surface.
