PE ----------------------------------- Green/Yellow
⚠️ The blue wire is not a return from the load; it is the permanent neutral. The motor direction is determined by which of the two phase wires (brown or black) receives 230V AC. schéma branchement volet roulant 3 fils
| Symptom | Likely Cause | Solution | |---------|--------------|----------| | Motor runs in opposite direction | Brown and black swapped | Invert them at switch or controller | | Motor only goes one way | One limit switch stuck or broken | Test continuity; replace motor head | | Motor does not move at all | No neutral to blue wire | Verify blue is connected to N | | Shutter stops mid-way | Overheating protection (thermal cutout) | Wait 15 minutes; check for obstruction | | Both directions dead but motor hums | Mechanical jam or failed capacitor (rare in 3-wire? Note: Some 3-wire motors have internal capacitor. Check datasheet) | Remove shutter fabric; check capacitor | Note: Some 3-wire motors have internal capacitor
