How to connect the thermocouple wiring of the temperature controller

1. Clearly define the wiring terminals
Firstly, it is necessary to clarify the wiring terminals of the temperature controller and thermocouple. Usually, the wiring terminals of the thermostat are marked as COM, NC, and NO, while the wiring terminals of the thermocouple are marked as+and -.

2. Cut off the power supply
Before making any wiring, be sure to cut off the power supply. This will ensure safety and avoid electric shock accidents.

3. Cable for connecting thermocouples
Firstly, connect the positive pole of the thermocouple (marked as+) to the COM terminal of the thermostat. Next, connect the negative pole of the thermocouple (marked as -) to the NO terminal of the temperature controller.

4. Connect the power cord
Next, connect the cable of the thermostat to the power cord. Connect the NC terminal of the thermostat to the "live" line of the power cord, and connect the COM terminal to the "ground" line of the power cord.

5. Check the wiring
After completing the connection, be sure to carefully check whether the wiring connection is secure and there is no looseness or short circuit. Ensure that all wiring is correct and error free.

6. Restore power supply
Afterwards, check all connections and reconnect the power. Ensure that the thermostat is working properly and can accurately read the temperature of the thermocouple.

During the wiring process, be sure to cut off the power supply to avoid electric shock accidents.

If you are unsure about the wiring, please consult a professional or read the device's user manual.

If any cable damage or poor thermocouple connection is found, please replace or repair it in a timely manner.

Before wiring, please ensure that you have relevant electrical knowledge and experience to ensure safe and correct wiring connections.

After wiring is completed, test and ensure that the insulation controller is working properly.

The above is an explanation about the wiring of the temperature controller thermocouple, hoping to be helpful to you. Remember, safety always comes first!
