| Symptom | Possible Cause | Relevance to This Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| No air control response | No 24 V DC supply or failed unit | ✅ High | Measure 24 V DC at the input terminals | Verify supply and fuse before replacement |
| Incorrect air output | Wrong setup or control signal mismatch | ✅ High | Check 0-10 V or 4-20 mA command signal | Confirm signal type and configuration |
| Robot alarm on startup | Incorrect first-time setup | ✅ High | Review robot setup and installed spare part data | Reinstall with the correct ABB setup file |
| Pressure unstable | Supply air problem or clogged pneumatic path | ✅ High | Measure inlet pressure and inspect hoses/valves | Check air system before changing the unit |
| Control range limited | Calibration or signal scaling issue | ✅ Medium | Verify 0-100% control range against actual command | Recheck scaling and setup parameters |
| Unit physically fits but does not work | Wrong part number or revision | ✅ High | Compare ACU-01B with 3HNA024871-001 on the label | Use only the exact ABB spare part ID |
