Press the key briefly once. The SV display digit will start flashing.

To enter the full configuration menu, press and hold the button for 3 to 5 seconds. 4. Parameter Configuration

Disclaimer: This guide covers general features common to FourTech’s popular models (e.g., 48x48, 48x96). Always refer to your specific model’s sticker for exact terminal numbers.

To keep your controller running smoothly, make sure to check your terminal screws regularly. Over time, heating and cooling cycles can cause them to loosen. If youg., FT-40, FT-90) fourtech temperature controller manual

Relay output (5A/250V AC), SSR drive (12V DC, 30mA), or Analog current/voltage (4-20mA, 0-10V).

: Depending on your hardware, you must select the correct output mode: Relay (020) : Best for mechanical contactors.

Fourtech temperature controllers are digital, microprocessor-based instruments designed for precise thermal regulation. They are widely used in industrial ovens, plastics manufacturing, packaging machinery, and environmental chambers. This comprehensive manual covers installation, wiring, configuration, and troubleshooting. 1. Technical Specifications and Initial Inspection

In the world of industrial automation and precise thermal management, the stands as a reliable, albeit technical, cornerstone. Whether you are managing a commercial espresso machine boiler or a high-stakes industrial oven, understanding the nuances of your controller’s manual is the difference between a stable process and a costly system failure. The Logic of the Controller: A Technical Foundation To keep your controller running smoothly, make sure

Connect Terminal 5 (+) and Terminal 10 (-) directly to the DC input terminals of your external SSR. Initial Configuration and Parameter Settings

Adjust HyS (Hysteresis) to create a dead-band buffer. This prevents your relays from switching on and off too quickly. PID Control and Auto-Tuning Best for high-precision thermal systems. To run the automatic calibration cycle: Access the configuration menu and locate the AT parameter. Change the value from oFF to on . Press to confirm. The AT light on the front panel will flash.

The "AT" light on the faceplate will blink. The controller will now "learn" the thermal dynamics of your machine.
