4. Installation
The XR02CX-5N0C1 controller is designed for panel mounting. Ensure all power is disconnected before proceeding with installation.
4.1 Panel Mounting
- Cut an opening of 71x29mm in the desired panel.
- Insert the controller into the opening from the front.
- Secure the controller using the provided mounting clips from the rear of the panel.
5. Wiring Diagram
Refer to the diagram below for correct electrical connections. Ensure all wiring is done by a qualified professional and complies with local electrical codes. The power supply voltage must match the controller's specified voltage (e.g., 230V~ 50-60Hz for the 220V model).
Terminal Connections:
- Terminals 1-2: Hot Key connection.
- Terminals 3-4: Digital Input for external signals.
- Terminals 5-6: NTC Probe input (Room temperature sensor).
- Terminals 7-8: Power Supply (Line, e.g., 230V~ 50-60Hz).
- Terminals 8-9: Compressor Output (Comp).
6. Operation
The controller features a simple interface for setting and monitoring temperature.
6.1 Front Panel Controls
- SET Button: Used to view and modify the setpoint temperature and access programming parameters.
- Up Arrow Button: Increases the displayed value or navigates through parameters.
- Down Arrow Button: Decreases the displayed value or navigates through parameters.
- AUX Button: Typically used for auxiliary functions or to initiate manual defrost cycles.
- Display: Shows the current temperature or parameter values.
6.2 Setting the Temperature Setpoint
- Press the SET button briefly to display the current setpoint.
- Press and hold the SET button for a few seconds until the setpoint value starts flashing.
- Use the Up or Down arrow buttons to adjust the setpoint to the desired temperature.
- Press the SET button again to confirm and save the new setpoint.
6.3 Defrosting
The controller supports shutdown defrosting. Consult the full programming manual (if available) for detailed defrost cycle settings. Manual defrost can typically be initiated by pressing and holding the AUX button.
7. Maintenance
Regular maintenance ensures the longevity and optimal performance of your temperature controller.
7.1 Cleaning
- Clean the front panel with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Ensure no liquids enter the controller unit, especially around the buttons and display.
7.2 Probe Inspection
- Periodically check the NTC temperature probe and its wiring for any signs of damage or corrosion.
- Ensure the probe is securely placed in the area where temperature needs to be measured.
7.3 Electrical Connections
- Occasionally inspect all electrical connections to ensure they are tight and free from corrosion.
- If any wiring appears damaged, replace it immediately.
8. Troubleshooting
This section provides solutions to common issues you might encounter.
| Problem | Possible Cause | Solution |
|---|---|---|
| Controller not powering on | No power supply; incorrect voltage; loose wiring. | Check power source; verify voltage matches controller; inspect wiring connections. |
| Incorrect temperature reading | Faulty NTC probe; probe not correctly installed; wiring issue. | Check probe connection; ensure probe is in correct location; replace probe if damaged. |
| Compressor not engaging/disengaging | Setpoint issue; relay fault; wiring to compressor incorrect. | Verify setpoint and differential settings; check compressor wiring; consult a technician if relay is suspected faulty. |
| Display shows error code | Sensor error; internal fault. | Refer to the full programming manual for specific error code meanings. Check sensor connections. |
9. User Tips
- Always ensure the power supply is stable and within the specified voltage range to prevent damage to the controller.
- For optimal temperature control, place the NTC probe in a location that accurately reflects the temperature of the controlled environment, away from direct airflow or heat sources.
- Familiarize yourself with the programming parameters to fine-tune the controller's behavior for your specific application.
- In case of power outages, most controllers retain their settings, but it's good practice to verify the setpoint once power is restored.
