7. Troubleshooting
This section provides guidance for common issues. For complex problems, contact technical support.
| Problem | Possible Cause | Solution |
|---|---|---|
| Controller not powering on | No power supply; incorrect wiring; internal fault. | Check power connections and voltage. Verify wiring. If problem persists, contact support. |
| ALARM indicator is on | System fault (e.g., overpressure, high temperature, motor overload). | Check the display for specific error codes or messages. Address the underlying issue in the compressor system. Press RESET after resolving the fault. |
| Compressor not starting | Incorrect start mode; safety interlock active; motor fault. | Verify START MODE setting. Check for active alarms or safety conditions. Consult compressor manual for motor diagnostics. |
| Inaccurate readings (PRES, TEMP, CURR, VOLT) | Sensor malfunction; wiring issue; calibration needed. | Inspect sensor connections. Check sensor integrity. Contact support for calibration procedures if necessary. |
8. User Tips
- Always ensure the controller is compatible with your specific air compressor model, especially for variable frequency units.
