This section provides basic troubleshooting steps for common issues. For more complex problems, refer to the detailed technical manual or contact Datakom support.
| Problem | Possible Cause | Solution |
|---|---|---|
| Controller does not power on. | No power supply; incorrect wiring; blown fuse. | Check battery connections and voltage. Verify power supply wiring. Check for blown fuses in the power circuit. |
| Generator fails to start in AUTO mode. | Mains power present; start inhibit active; engine fault; low fuel. | Verify mains status. Check controller settings for start inhibits. Inspect engine for fuel, oil, and battery issues. Check alarm logs on the controller. |
| Communication issues (USB/Ethernet). | Incorrect cable; driver issues; network configuration; module not installed. | Ensure correct cable type and connection. Install necessary drivers for USB. Verify network settings (IP address, subnet mask). Confirm communication module is correctly installed. |
| Alarm indication on display. | Engine fault (e.g., high temperature, low oil pressure); sensor malfunction. | Note the specific alarm code/message. Refer to the detailed manual for alarm definitions. Address the underlying engine or sensor issue. |
Always ensure safety precautions are followed when troubleshooting electrical systems. If you are unsure, consult a qualified technician.
