How to Change Input Type to PT100 on TCN5 Temperature Controller

How to Change Input Type to PT100 on TCN5 Temperature Controller

The TCN5 series temperature controller supports various input types such as thermocouples (e.g., K-type) and RTDs (e.g., PT100). Depending on your application, you may need to change the sensor input type. This guide will walk you through how to switch the TCN5 input from K-type to PT100.

Step-by-Step Instructions:

1. Enter the Parameter Setting Mode:
   Press and hold the SET key for about 3 seconds until the screen displays P-1.
   
2. Enter Advanced Menu:
   Use the ▲ keys to adjust the P-1 to P-2, then press SET again to enter the advanced parameter menu.
   
3. Find the Input Type Parameter (InP):
   Using SET to locate the Inp parameter, which controls the input type.
   
4. Change Input Type to PT100:
   Default is usually K, (K-type thermocouple). Change the value to Pt. Press SET to confirm.
   
5. Save and Exit:
   Press and hold SET to exit and save changes. The controller will now operate in PT100 mode.
   

Important Notes:

• Always refer to the official manual for specific parameter codes, as they may vary slightly across models.
  
• After changing the input type, power-cycle the device to ensure proper recognition.
  
• If the display shows abnormal readings (like “---” or fixed values), check the PT100 wiring connections.
  

Use Case Example:

PT100 RTDs are ideal for precise temperature control, especially in low-temperature environments such as:

• Laboratory incubators
  
• Cooling systems
  
• Food processing equipment
