Understanding buzzer alarm signals is essential for fast troubleshooting during elevator maintenance. Here’s a simplified reference based on KONE system buzzer codes:
🔔 Buzzer Code Basics
- *= Short beep
- -= Long beep
- ( )= Pause ~1 sec
- (q)= Pause ~15 sec
- (m)= Pause ~60 sec
- ----= Continuous beeping
⚙️ Common Alarm Codes & Meanings
- Drive module overheat→ (-m)
• Motor overheat → (* m)
• Resolver angle = 0 (not adjusted) → (**** q)
• Resolver auto-adjust (up direction) → ()
• Resolver auto-adjust (down direction) → ()
• Resolver adjustment error → (-)
• Resolver angle not detected (check motor U/V wiring) → (-)
• SETUP not performed → (-* m)
• SETUP active → (-)
• Error detected during SETUP → (-**** q)
• NTS fault (deceleration triggered in normal mode) → (* q)
• Parameters changed → (* q)
• Position error (V3F25) → (*-)
• Buffer & traction test → (----)
💡 Tips
- Always match buzzer patterns carefully—timing matters
- Most faults relate to resolver signals, setup status, or wiring issues
- Re-check connections and parameter settings before replacing parts
