Introduction
This manual provides essential information for the proper installation, operation, and maintenance of the Secop 101N0510 Electronic Unit. This unit is specifically designed to control BD35F and BD50F DC compressors, commonly found in refrigeration systems. Please read these instructions carefully before proceeding with installation or operation to ensure safe and efficient use.
Safety Information
Always observe basic safety precautions when installing or servicing electrical components. Failure to do so may result in personal injury or damage to the equipment.
- Disconnect Power: Ensure all power sources are disconnected before beginning any installation or maintenance work.
- Qualified Personnel: Installation and service should only be performed by qualified technicians.
- Correct Voltage: Verify that the power supply voltage matches the requirements of the electronic unit (12V/24V DC).
- Proper Fusing: A pre-fuse is required for the DC power supply to protect the unit and system from overcurrent.
- Avoid Moisture: Do not expose the electronic unit to moisture or extreme temperatures.

- Mounting: Securely mount the electronic unit in a location that is dry, well-ventilated, and protected from physical damage. Ensure adequate space for wiring and heat dissipation.
- Compressor Connection: Connect the electronic unit directly to the BD35F or BD50F DC compressor. The connectors are typically plug-and-play, designed to fit only one way. Refer to the compressor's manual for specific connection points.
- Power Supply Connection: Connect the 12V or 24V DC power supply to the designated terminals on the electronic unit. A pre-fuse is required in the DC power line to protect the system. Observe correct polarity (+ and -).
- Thermostat/Control Connection (Optional): If using an external thermostat or control, connect it to the appropriate terminals as per the wiring diagram provided with your compressor or refrigeration system.
- Final Check: Before applying power, double-check all connections for security and correct polarity.

Operating Instructions
Once installed correctly, the Secop 101N0510 Electronic Unit operates automatically to control the compressor based on the system's demands and thermostat settings.
- Power On: Apply the appropriate 12V or 24V DC power to the unit. The compressor should start operating if the thermostat calls for cooling.
- Thermostat Control: The electronic unit responds to signals from the connected thermostat to cycle the compressor on and off, maintaining the desired temperature.
- Voltage Monitoring: The unit includes built-in low voltage protection to prevent excessive discharge of the battery. If the voltage drops below a safe level, the compressor will temporarily shut off and restart when the voltage recovers.
Maintenance
The Secop 101N0510 Electronic Unit is designed for reliable, maintenance-free operation. However, periodic checks of the system can help ensure longevity.
- Cleanliness: Keep the unit free from dust and debris to ensure proper heat dissipation.
- Connection Integrity: Periodically inspect all electrical connections for tightness and signs of corrosion.
- Ventilation: Ensure that the mounting area remains well-ventilated to prevent overheating.
Troubleshooting
If the refrigeration system is not operating as expected, consider the following common issues:
| Problem | Possible Cause | Solution |
|---|---|---|
| Compressor does not start | No power supply, low battery voltage, faulty thermostat, loose connections. | Check power source and fuse. Charge battery. Test thermostat. Verify all wiring connections. |
| Compressor cycles on/off rapidly | Low battery voltage, insufficient ventilation, refrigerant issues. | Check battery charge. Ensure adequate airflow around the unit and compressor. Consult a refrigeration technician for refrigerant issues. |
| Unit is warm to the touch | Normal operation, or insufficient ventilation. | Some warmth is normal. Ensure proper ventilation around the unit. If excessively hot, check for overloads or blockages. |
