Specific terminals for Thermocouples (K, J, E type) or RTDs (Pt100).
Small LEDs (usually labeled OUT, ALM, or AT) that show if the heater is active, if an alarm is triggered, or if "Auto-Tuning" is in progress. 2. Basic Configuration and Wiring
This usually indicates a sensor error. Check if your thermocouple is broken or if the wires are swapped (Reverse Polarity). fourtech temperature controller manual
The "AT" light on the faceplate will blink. The controller will now "learn" the thermal dynamics of your machine.
Mastering Your Fourtech Temperature Controller: A Comprehensive Guide Specific terminals for Thermocouples (K, J, E type)
Before diving into the settings, familiarize yourself with the interface. Most Fourtech models feature: Displays the current temperature. SV (Set Value): Displays your desired target temperature.
Once the light stops blinking, the controller has saved the optimal PID settings. 6. Common Error Codes Basic Configuration and Wiring This usually indicates a
Verify the Hy (Hysteresis) or AL settings to ensure the alarm threshold isn't set too close to your working temperature.
By following these steps, you can bypass the frustration of a complex manual and get straight to precise temperature management.
