- Common Faults & Solutions
| Fault Phenomenon | Possible Causes | Solutions |
| Contact failure | Improper installation, stuck mechanism, damaged linkage | Reinstall firmly, clean foreign matters, replace contact block |
| Poor contact | Oxidation, loose terminal, severe wear | Polish contact surface, retighten wiring, replace component |
| Contact ablation | Overload current, frequent switching, overvoltage | Control current within 2.5A, reduce frequent operation, verify voltage range |
| Difficult installation | Model mismatch, wrong direction, broken buckle | Confirm GV2/GV3 compatibility, install as arrow direction, replace part |
