4. Setup

4.1 Mounting

The TC4S-N4N is designed for panel mounting. Ensure adequate space for ventilation and access to wiring terminals. Secure the controller using the provided mounting clips or screws into a standard panel cutout.

4.2 Wiring Instructions

Refer to Figure 3.2.2 for the general terminal layout. Always ensure power is disconnected before wiring.

1. Power Supply: Connect the 100-240VAC power supply to terminals 5 and 6 (as indicated on the device label).
2. Sensor Input: Connect your temperature sensor (e.g., thermocouple, RTD) to the designated 'TC' terminals (e.g., 9 and 10). Ensure correct polarity if applicable.
3. SSR Output: If using Solid State Relay (SSR) output, connect to terminals 1 and 2. This output typically provides a low-voltage signal to drive an external SSR.
4. Relay Output: If using Relay output, connect your load to terminals 3 and 4. This is a dry contact relay, rated for 250VAC 3A.
5. Alarm Output (if applicable): Some models may have additional alarm outputs (e.g., AL1, AL2). Refer to your specific model's label for connections.

Double-check all connections for tightness and correctness before applying power.

5. Operating Instructions

5.1 Basic Operation

Once powered on, the controller will display the current process value (PV) and the set value (SV).

• Setting the Temperature (SV): Press the MODE button briefly to enter the set value adjustment mode. Use the Up and Down arrow buttons to adjust the desired temperature. Press MODE again to confirm and exit.
• Temperature Unit: The display indicates whether the temperature is in Celsius (°C) or Fahrenheit (°F). This setting is typically configured in advanced parameters.

5.2 Advanced Settings

Accessing advanced settings usually involves pressing and holding the MODE button for several seconds. This allows configuration of parameters such as:

• PID control parameters (P, I, D)
• Alarm settings (high/low limits)
• Input sensor type
• Temperature unit selection (°C/°F)
• Output type configuration (heating/cooling)

Refer to the detailed parameter list (not provided in this general manual) for specific codes and adjustment ranges for your model.

6. Maintenance

Regular maintenance ensures the longevity and accuracy of your temperature controller.

• Cleaning: Gently wipe the display and casing with a soft, dry cloth. Do not use abrasive cleaners or solvents.
• Inspection: Periodically check wiring connections for looseness or signs of corrosion. Ensure the mounting is secure.
• Environment: Keep the controller in a clean, dry environment, free from excessive dust, vibration, and extreme temperatures.

7. Troubleshooting

If you encounter issues with your TC4S-N4N controller, refer to the following common problems and solutions:
