3. Producto terminadoview

The Yudian AI-518 series temperature controllers are advanced instruments featuring high measurement accuracy and stable control performance. They utilize PID (Proportional-Integral-Derivative) control algorithms to maintain precise temperature levels in various processes. The front panel typically includes dual digital displays for Process Value (PV) and Set Value (SV), along with operational buttons for configuration and control.

3.1 Características principales

• Alta precisión y resolución de medición.
• Advanced PID control with auto-tuning function.
• Multiple input types (thermocouple, RTD, linear voltage/actual).
• Various output options (relay, SSR, linear current/voltagmi).
• Alarm functions with configurable modes.
• Digital filtering and sensor error compensation.
• Durable ABS material casing.

3.2 Front Panel Layout (AI-518G Example)

4. Instalación y configuración

4.1 Montaje

The AI-518 series controllers are designed for panel mounting. Ensure adequate space for ventilation and wiring. Cut a panel opening according to the dimensions provided in the product specifications (refer to Section 7). Secure the controller using the provided mounting brackets.

4.2 Cableado

All wiring should be performed with the power disconnected. Refer to the wiring diagram typically found on the side or top of the controller casing, or in a separate wiring guide. Ensure correct connections for:

• Fuente de alimentación: Connect to the specified AC or DC voltage.
• Entrada del sensor: Connect your temperature sensor (thermocouple, RTD) to the designated input terminals. Observe polarity for thermocouples.
• Salida de control: Connect the heating/cooling element or SSR to the control output terminals.
• Salidas de alarma: If utilized, connect external alarm devices to the alarm output terminals.
• Toma de tierra: Ensure proper grounding for safety and noise reduction.

Note: Incorrect wiring can damage the controller or connected equipment. If unsure, consult a qualified electrician.

5. Instrucciones de funcionamiento

5.1 Encendido y pantalla inicial

Upon powering on, the controller will typically display the Process Value (PV) on the upper display and the Set Value (SV) on the lower display. The PV indicates the current measured temperature, while the SV is the desired target temperature.

5.2 Configuración del valor establecido (SV)

1. Presione el COLOCAR Presione el botón una vez. La pantalla SV comenzará a parpadear.
2. Utilice el UP (▲) y ABAJO (▼) botones para ajustar la temperatura deseada.
3. Presione el COLOCAR button again to confirm the new SV. The display will stop flashing.

5.3 Accessing Parameter Menus

To access advanced parameters (e.g., input type, output mode, PID parameters, alarm settings), press and hold the COLOCAR button for several seconds until the first parameter code appears. Use the COLOCAR button to cycle through parameters and the UP/ABAJO buttons to change values. Refer to the detailed parameter list in the full technical manual for specific codes and ranges.

5.4 Auto-Tuning (AT) Function

The auto-tuning function automatically calculates optimal PID parameters for your specific process. To initiate auto-tuning:

1. Set the desired SV.
2. Access the parameter menu and locate the auto-tuning parameter (often labeled AT o similar).
3. Set the AT parameter to '1' (ON) and confirm. The controller will begin the auto-tuning process, which may involve temperature cycling.
4. Once complete, the AT parameter will automatically revert to '0' (OFF), and the newly calculated PID parameters will be saved.

It is recommended to perform auto-tuning when the controller is first installed or if the process characteristics change significantly.

6. Mantenimiento

6.1 Limpieza

Limpie el panel frontal con un paño suave yamp paño. No utilice limpiadores abrasivos, disolventes ni productos químicos fuertes, ya que pueden dañar la pantalla oasing. Ensure no liquid enters the controller.

6.2 Inspección

Periodically inspect wiring connections for looseness or corrosion. Check the sensor for damage or degradation. Ensure the operating environment remains within specified conditions.

6.3 Calibración

If the temperature readings appear inaccurate, the sensor or controller may require calibration. Refer to the advanced parameter settings for calibration offsets, or consult a qualified technician for professional calibration services.
