Inverter Failure

What does 09 mean?

This error indicates a specific issue with the inverter, manifested as an error signal appearing at input Port X11 of the master control PCB. This error is recorded if the inverter fault signal persists for 10 seconds while the master control PCB is determined to be operating correctly.

• An internal fault or malfunction within the inverter unit itself.
• An active fault signal being received at input Port X11 of the master control PCB.
• Communication error or disruption between the inverter and the master control PCB.

Click steps to track your progress.

1. 1

   Check the inverter's own fault display or diagnostic LEDs for any specific error codes or status indications.

2. 2

   Verify the wiring and secure connection between the inverter and input Port X11 on the master control PCB.

3. 3

   Ensure the master control PCB is functioning correctly by checking its status indicators or diagnostic outputs.

4. 4

   Measure the input voltage supplied to the inverter to confirm it is within specified operational limits.
