Smart Power System Motor Wiring  Diagnostic Guide 

The Smart Power System connects to the LiteGait actuator via a black, five‑pin female plug called an actuator cable connector. A loose connector or internal wiring fault will disable the movement of the upper and lower columns, and the control box LED will display a solid red light indicating to “Contact Support.”

Symptoms:

• Control box LED displays red color code, indicating to CONTACT SUPPORT.

• Top column does not move and pressing the hand-switch single down arrow button does not move either column.

• Top column does not move and pressing the hand-switch single down button only moves the lower column.
• Lower column does not move and pressing the hand-switch single arrow up button does not move either column. 

Step-By-Step Troubleshooting

Check for a loose connection between the motor and actuator cable connector

• • The connector is located on the back side of the unit

    

  • Remove the magnetic cover to find the connector
    
    
  • Reseat the connector 
    

    • If the control red light disappears, test the equipment to confirm functionality

      • Do both columns move now?

    • If the red light does not disappear and the issues persists, move on to the next steps

Actuator cable connector wiring layout and symptom identification

⬛ BLACK .............. Lower Column

⬜ WHITE .............. Lower Column

Identify the Symptom and faulty wire

• • Top column is disabled - there is no movement from the top column when any of the hand-switch buttons are pressed.

• • Top column is disabled - there is no movement from the top column when any of the hand-switch buttons are pressed, and pressing the single arrow down button does not move the top or lower columns 

• • Lower column is disabled - there is no movement from the lower column when any of the hand-switch buttons are pressed, and pressing the single up arrow does not move the top or lower columns 

Check the connector’s internal wiring for faulty connections 

• • Open the connector by removing the two Phillip screws that secure the housing
    

• • When the housing top cover is removed, the internal wiring and the set screws that secure the wiring should be visible

• • If a loose wire is identified:

    1. use a small flathead screwdriver to loosen the set screw for the affected wire

    2. push the wire further into its slot

    3. once the wire is adjusted, tighten the set screw to secure the wire

    4. check if the red light has disappeared
