| 39 | 10.9 | 12.2 | 17.0 | 24.5 | 24.7 |
| 47 | 11.0 | 12.3 | 17.0 | 24.7 | 24.9 |
Note: The 12V Max column indicates the maximum voltage the 12V system can handle before potential issues. Always ensure your battery voltage remains within safe operating limits.
4. Maintenance
The Secop Electronic Controller is designed for durability and reliability. Regular maintenance is minimal but important for ensuring long-term performance.
- Cleaning: Keep the controller free from dust, dirt, and moisture. Use a soft, dry cloth for cleaning. Do not use abrasive cleaners or solvents.
- Connections: Periodically check all electrical connections to ensure they are tight and free from corrosion. Loose connections can lead to intermittent operation or damage.
- Inspection: Inspect the unit for any signs of physical damage, such as cracks or frayed wires. If damage is found, discontinue use and contact support.
5. Troubleshooting
If you encounter issues with your electronic controller, refer to the following common troubleshooting steps. For more complex problems, consult a qualified technician.
- No Power: Check the power supply connections and ensure the fuse is intact. Verify the main switch is in the 'ON' position.
- Compressor Not Running: Ensure the battery voltage is above the cut-in threshold. Check all wiring connections to the compressor and controller.
- LED Indicator: Observe the LED indicator for diagnostic codes. Consult the compressor's manual or Secop documentation for specific LED flash codes and their meanings.
- Overheating: Ensure adequate ventilation around the compressor and controller. Check the fan operation if applicable.
