Panel balance command changes requested AC waveform behavior.
Fault route
WSE AC Balance Control Not Working Diagnostic
A WSE AC/DC TIG route for balance-control faults.
Quick Answer
If WSE AC balance control does not work, do not start at the primary inverter. Check the balance command from the AC/DC panel, the control-board processing path and secondary inverter response.
- DC output can be normal while AC balance remains faulty.
- Balance faults belong to the AC command and secondary switching layer.
- Confirm panel command before replacing secondary inverter devices.
WSE AC balance control route
Balance command must reach and affect secondary switching.
Command must be processed into secondary-stage control.
Driver must translate command into switching behavior.
Switching devices create the balance effect.
Observe AC behavior after command changes.
Balance evidence table
| Evidence | Meaning | Repair direction |
|---|---|---|
| Balance setting has no response | Panel command or control path issue. | Check panel and control-board command. |
| Command changes but output does not | Secondary driver/inverter response issue. | Check secondary stage. |
| DC mode normal | Primary output may be healthy. | Focus AC secondary layer. |
| AC output missing entirely | Broader secondary failure. | Use AC-output-missing route. |
