5 steps to start using DCL actuator
How-tos
How to Set the Hysteresis of the Actuator?
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% to 5%.
How to control DCL actuator through modbus by 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 actuator. 3.Close the “Connect to”
How to calibrate the input signal of the 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 red LED lights up. (After
How to Configure the ON-OFF Actuators with Position Transmitter?
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

Can DCL Actuators Be Used in High-Altitude Areas?
High-altitude environments present unique challenges that can impact the performance of DCL electric actuators. This report evaluates their usage at 3,000 meters above sea level. 1. How High Altitude Affects Electrical Products As altitude increases:✔ Air density and pressure decrease, leading to lower insulation strength and increased risk of electrical breakdown.✔ Cooling efficiency decreases, causing higher temperature rise in motors
Why Do Some Actuators Need Explosion Protection?
1. What is an Explosion? An explosion occurs when flammable substances mix with oxygen and ignite under certain conditions. If the reaction speed exceeds the speed of sound, it results in a destructive explosion wave. 2. What is Explosion Protection? To prevent explosions, at least one of the three key factors must be controlled: Flammable substances Oxygen Ignition source
