• Su'ega So'oga: Occasionally check all wiring connections to ensure they remain tight and secure.

7. Faʻafitauli

• No "ON" LED illumination:
  • Check if the main AC power supply is connected and active.
  • Verify the input wiring (N, L) is correct and secure.
• "OVERLOAD" LED illuminates:
  • This indicates an overcurrent condition or a short circuit on the 24V DC output or connected DUOX Plus bus lines.
  • Immediately disconnect the main AC power supply to the unit.
  • Inspect all connected DUOX Plus equipment and wiring for short circuits or excessive load.
  • After resolving the issue, wait approximately one minute before reconnecting the main AC power supply to allow the electronic fuse to reset.
  • If the problem persists, the connected equipment may be drawing too much current, or the power supply itself may be faulty.
• Leai Voltage / Sin Tensión / Nicht Spannung:
  • This label on the unit indicates the absence of voltage. If the "ON" LED is off and there is no output, refer to the "No 'ON' LED illumination" troubleshooting steps.
