Hoe stel ik de hysteresis van de actuator in?

Setting the hysteresis allows the actuator to better match PID closed-loop control applications. Steps to Set the Hysteresis: Turn the S-A switch (highlighted in the red box below) to position 2. Rotate the adjustment knob (highlighted in the yellow box) to set the hysteresis. Each scale mark represents 0.5%. The adjustable hysteresis range is 0.5% […]

Hoe een DCL-actuator via Modbus te besturen met vaTestTool_DCL.exe

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 […]

Hoe kalibreer ik het ingangssignaal van de actuator?

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 […]

Hoe configureer ik de aan/uit-actuatoren met een positiezender?

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 […]

Hoe stel ik een modulerende elektrische klep in?

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 […]

How to Set Up an ON-OFF Electric Valve?

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 […]

How to install the actuator onto the valve?

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) […]
