Indicator Light Status Explanation
Note: To simplify the display, the number of red light flashes determines the current status—whether in protection mode or an abnormal state.
| Definition | Red Light Flashes | Suggested Actions |
|---|---|---|
| Leakage | 1 | Power off and restart to recover. Check for potential leakage risks in the wiring. |
| Overvoltage | 2 | Auto recovery after voltage stabilizes. |
| Undervoltage | 3 | Auto recovery after voltage stabilizes. |
| Overcurrent | 4 | Level 1 overcurrent has limited auto-recovery attempts. Level 2 overcurrent or short circuit requires a power-off restart. Check for potential short circuit risks. |
| Overtemperature | 5 | Auto recovery after temperature normalizes. |
| Leakage Self-Test Failure | 6 | Restart to check if recovery occurs. If multiple failures persist, check the leakage module and wiring. Contact support if unresolved. |
| Reserved | 7 | - |
| CP Level Error | 8 | Power cycle the system. If the issue persists, contact support. |
| Relay Error | 9 | Power cycle the system. If the issue persists, contact support. |
| Auxiliary Processor Error | 10 | Power cycle the system. If the issue persists, contact support. |
| System 12V Error | 11 | Power cycle the system. If the issue persists, contact support. |
