Universal Controller Reassembly

This procedure covers reassembly of the Universal Controller (UC) on units SC00009 and later.

Before You Begin

This procedure assumes:

  • The Feed Controller is already installed.

  • The Engine Control panel is already installed.

  • The battery cables are connected to the battery terminals.

  • The Feed Controller cable is connected to the Junction Box.

The following diagram shows an overview of the Universal Controller assembly on the rear AeroCube.

      UC to Feed Controller

      The UC is located behind the Rear Feed Controller.

      1. The cables that connect the UC to the Feed Controller are already connected at the UC.

      2. Take the end of the cable located behind the Front Feed Controller. Pass the cable end through the cable hole next to the Front Feed Controller and connect it to the Front Feed Controller.

      3. Take the end of the cable located behind the Rear Feed Controller. Pass the cable end through the cable hole next to the Rear Feed Controller and connect it to the Rear Feed Controller.

        Antenna to UC

        The corner post with the antenna is located to the right of the Rear Feed Controller.

        1. Gently pull the cable ends out from the bottom of the post.

        2. Pass the cable ends through the cable hole.

          Verify Power

          After connecting all cables, the UC should be powered on. The green circle light on top of the UC enclosure should be lit.

          1. Check the green circle light on top of the UC enclosure.

          2. If the light is not lit, press the Power button once.
            The Power button has a circular light around it.
            The light turns green when the UC is powered on.
