アクチュエータのヒステリシスを設定するには？
ヒステリシスを設定することにより、アクチュエータは PID クローズドループ制御アプリケーションにより適合することができます。ヒステリシスを設定する手順S-Aスイッチ（下図の赤枠）を2の位置に回します。調整ノブ（黄色のボックスで強調表示）を回してヒステリシスを設定します。各スケールマークは0.5%を表します。調整可能なヒステリシスの範囲は0.5%～5%です。
vaTestTool_DCL.exeによるDCLアクチュエータのModbus制御方法
1.Open vaTestTool_DCL-v1.31.exe. 2.The application will popup a “Connect to” dialog to set the target device id and local computer RS232 port parameters as follow. Choose the COM port which connected to the USB-RS485 connector. Select the modbus baud rate (the default baudrate on DCL actuator now is 9600). Click on “CONNECT”button to connect to the actuator. 3.Close the “Connect to” windows and now you are in operation windows. Now you can click on “OPEN/CLOSE/STOP”button to control the actuator. Your can input in “Set position”text frame and then click on “SET POS” button to let actuator drive the valve to the position as you wish. You can click on “4-20mA INPUT”to let […]
アクチュエータの入力信号の校正方法は？
When the actuator’s valve position does not match the 4–20mA input signal (resulting in a discrepancy between the feedback signal and the input signal), you can calibrate the input signal to eliminate this deviation. 6 Simple Steps for Calibration: Turn the S-A switch to position 2. Press and hold the Set button until the L2 red LED lights up. (After releasing, L2 will start flashing.) Within 5 seconds, press and hold both the Open and Shut buttons simultaneously. L2 flashing will switch to L3 flashing, indicating that the control module has entered input signal calibration mode. Apply a 4mA signal from the signal source, then press and hold Set and […]

1. Mechanical Installation 1. Mechanical Installation Refer to the “How to Install the Actuator onto the Valve” section to correctly install the actuator onto the valve and manually operate it to confirm proper functioning. Follow the guidelines in “How to Set the ON-OFF Electric Valve” to properly adjust the actuator’s electrical limits (close limit CLS and open limit OLS) and mechanical limits. Important Notes: Unless specified otherwise, the actuator’s stroke angle between the fully closed and fully open positions is typically 90° during factory debugging. The output current corresponds to 4mA when fully closed and 20mA when fully open. The position potentiometer has been calibrated during the valve matching process, […]

1. Installing the Actuator onto the Valve Follow the installation instructions in “How to Install the Actuator onto the Valve” to correctly install the actuator on the valve. Confirm normal operation by manually testing the valve movement. 2. Adjusting the Mechanical Limits for Fully Closed Position Use the handwheel to move the valve to the fully closed position. Ensure the mechanical limit stop does not touch the adjustment screw or housing. Loosen the scale plate locking screw, adjust the scale plate so that the pointer aligns with the 0 degree mark (SHUT position), and then tighten the locking screw. 3. Adjusting the Mechanical Limits for Fully Open Position Use the […]

1. Adjusting the Fine-Tuning Electrical Limit Full Close Adjustment: Use the handle to drive the valve to the fully closed position. Loosen the scale plate locking screw and adjust the scale plate so that the pointer aligns with the 0 mark (SHUT direction). Then, tighten the screw. Using a 2mm hex wrench, turn the closing adjustment shaft (S) clockwise until the travel stop D1 rotates clockwise and triggers K2 and K1 sequentially, making a clicking sound. Stop turning when K1 clicks, completing the full-close position adjustment. Full Open Adjustment: Use the handle to drive the valve to the fully open position so the pointer aligns with the 0 mark (OPEN […]
バルブへのアクチュエータの取り付け方法は？
Installation Steps Manually rotate the valve to check for any abnormalities and ensure the valve is in the fully closed position. Secure the mounting bracket onto the valve. Fit one end of the coupling onto the valve stem. Manually drive the electric actuator to the fully closed position (pointer aligned with SHUT or zero-degree marking) and insert the actuator’s output shaft into the square hole of the coupling. Tighten the bolts connecting the bracket, actuator, and valve body. Manually operate the actuator through its full stroke to ensure smooth movement, no misalignment, and no eccentricity. Check if the valve can fully open and fully close within the actuator’s position indicator […]
