Input Methods:
- The controller accepts thermocouple inputs with index numbers K, J, E, and N. Ensure the correct thermocouple type is selected in the controller's settings to match your sensor.
Important: Always ensure power is disconnected before making any wiring connections. Incorrect wiring can damage the device or cause safety hazards.
7. Instruccions de funcionament
7.1 Encès
Once properly wired and installed, apply power to the controller. The display will show the current Process Value (PV) and Set Value (SV).
7.2 Setting the Temperature (SV)
- Premeu el botó MODE button briefly to enter the set value adjustment mode. The SV display will flash.
- Utilitza el ▲ i ▼ botons per ajustar la temperatura desitjada.
- Utilitza el ◀ (Shift) button to move between digits for faster adjustment.
- Premeu el botó MODE button again to confirm the new set value and exit the adjustment mode.
7.3 Configuració dels paràmetres
The controller has various parameters for advanced configuration, including control mode (PID/ON-OFF), alarm settings, and thermocouple type. Accessing and adjusting these parameters typically involves pressing and holding the MODE button for several seconds to enter the parameter menu. Refer to the detailed parameter list in the full manual for specific instructions on each setting.
- Mode de control: Select between PID control for precise regulation or ON/OFF control (when P=0) for simple switching.
- Configuració d'alarma: Configure the single alarm with 6 modes (high deviation, low deviation, process value alarm).
- Tipus de termoparell: Ensure this matches your connected sensor (K, J, E, N).
- Unitat de temperatura: Switch between Celsius (℃) and Fahrenheit (°F) as needed.
7.4 PID Auto-Tuning (AT)
For optimal performance with PID control, auto-tuning is recommended. This process automatically calculates the best PID parameters for your specific system. Consult the full manual for detailed steps on initiating and completing the auto-tuning process. The AT indicador lamp will illuminate during auto-tuning.
