Abnormal Power Synchronous Signal

What does 08 mean?

An abnormality is detected in the power synchronous signal, which is crucial for the controller circuit board to synchronize with the incoming power frequency. A faulty signal can lead to unstable operation of power components and incorrect timing control.

• Abnormal signal detected in the power synchronization process.
• Phase imbalance in the incoming power.
• Faulty power supply board.
• Issues with the synchronizing circuitry.
