3.2 Front Panel Layout (AI-518G Example)

Figure 1: Front panel of the Yudian AI-518G PID Temperature Controller. It features a dual digital display, with the upper red display showing the Process Value (PV) and the lower green display showing the Set Value (SV). Below the displays are indicator lights for various statuses (MAN, PRO, MO, COM, OP1, OP2, AL1, AL2, AUT, AUX) and control buttons including 'Set', 'Up', 'Down', 'Run', 'Stop', and 'A/M' (Auto/Manual).

4. インストールとセットアップ
4.1 取り付け
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配線
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:
- 電源: Connect to the specified AC or DC voltage.
- センサ入力: Connect your temperature sensor (thermocouple, RTD) to the designated input terminals. Observe polarity for thermocouples.
- 制御出力: Connect the heating/cooling element or SSR to the control output terminals.
- アラーム出力: If utilized, connect external alarm devices to the alarm output terminals.
- 接地: Ensure proper grounding for safety and noise reduction.
注意:配線を誤ると、コントローラーまたは接続機器が損傷する可能性があります。不明な場合は、資格のある電気技師にご相談ください。
5. 操作手順
5.1 電源投入と初期表示
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 Setting the Set Value (SV)
- を押す セット ボタンを一度押します。SVディスプレイが点滅を始めます。
- 使用 UP (▲) そして 下 (▼) buttons to adjust the desired temperature.
- を押す セット 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 セット 最初のパラメータコードが表示されるまで、ボタンを数秒間押し続けます。 セット ボタンを押すとパラメータが切り替わり、 UP/下 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:
- Set the desired SV.
- Access the parameter menu and locate the auto-tuning parameter (often labeled AT または類似)。
- Set the AT parameter to '1' (ON) and confirm. The controller will begin the auto-tuning process, which may involve temperature cycling.
- 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. メンテナンス
6.1 クリーニング
フロントパネルを柔らかい布で拭いてください。amp 布で拭いてください。研磨剤入りの洗剤、溶剤、または刺激の強い化学薬品は使用しないでください。ディスプレイやコンピューターに損傷を与える可能性があります。asing. Ensure no liquid enters the controller.
6.2 検査
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 キャリブレーション
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.
