• Alimentare electrică: Connect the AC power supply (AC100~242V) to terminals L and N as indicated.
• Intrare senzor: Connect your temperature sensor (e.g., thermocouple, RTD) to the designated input terminals (e.g., 1, 2, 3, 4, 5). Refer to the diagram for specific sensor type connections.
• Conexiuni de ieșire: Connect your heating/cooling element or other controlled device to the output terminals (e.g., 6, 7, 8, 9, 10) according to your controller's output type (Relay, SSR, 0-22mA, SCR).

5. Instrucțiuni de utilizare

5.1 Operare de bază

Upon power-up, the controller will display the Process Value (PV) and Set Value (SV).

• Temperatura de setare (SV): Apăsați tasta SET button once. The SV display will flash. Use the Up şi Jos arrow buttons to adjust the desired temperature. Press SET din nou pentru a confirma și a ieși.
• Parameter Access: Țineți apăsat butonul SET button for several seconds to enter the parameter setting menu. Use the arrow buttons to navigate and adjust parameters.

5.2 PID Control and Auto-Tuning

The XMTG-8 utilizes PID (Proportional-Integral-Derivative) control for stable and accurate temperature regulation. For optimal performance, auto-tuning is recommended after initial setup or if the process characteristics change significantly.

• Auto-Tuning (AT): Refer to the specific parameter settings in the full product manual for initiating auto-tuning. During auto-tuning, the AT indicator light will illuminate, and the controller will cycle the output to determine optimal PID parameters.

5.3 Ramp/Soak Functionality

The XMTG-8 supports ramp/soak programming, allowing for complex temperature profiles with defined heating/cooling rates (ramps) and holding periods (soaks). Detailed programming steps for ramp/sak profiles are typically found within the advanced parameter settings of the controller.

5.4 Setări de alarmă

The controller features one or two alarm outputs (AL1, AL2). Alarm parameters can be configured to activate based on deviations from the setpoint, absolute temperature limits, or other conditions. Adjust alarm types and values in the parameter menu.

6. Întreținere

Regular maintenance ensures the longevity and reliable operation of your temperature controller.

• curatenie: Ștergeți ușor ecranul șiasing with a soft, dry cloth. Do not use abrasive cleaners or solvents. Ensure no liquids enter the unit.
• Inspecţie: Periodically check all wiring connections for tightness and signs of wear or damage. Inspect the mounting for security.
• Conditii de mediu: Verificați dacă mediul de operare se încadrează în intervalele de temperatură și umiditate specificate.
