Why is my Samson 3730 Valve Positioners actuator moving in the wrong direction?
If your Samson Valve Positioner's actuator moves in the wrong direction, first check the characteristic setting. Also, inspect the piping and the configuration of the mounting parts.
How to fix slow movement of actuator in Samson 3730 Valve Positioners?
If the actuator on your Samson Valve Positioner moves too slowly, you should check the supply pressure. Additionally, consider deactivating any software restrictions. Inspect the cross-section of the piping and screw fittings, and verify the configuration of the mounting parts.
What to do if Samson 3730 Valve Positioners leaks air?
If you notice air leaks from your Samson Valve Positioner, examine the attachment. Also, check the seals in the connecting plate.
How to troubleshoot a Samson Valve Positioners with no display reading?
If there is no reading on the display of your Samson Valve Positioner, start by checking the electrical connection and electrical power. Also, check the ambient temperature, making sure it's within the display's operating range of –30 to +65 °C.
What to do if the actuator stem does not move on demand in my Samson Controller?
If the actuator stem on your Samson Controller isn't moving, first, check for any blockages. Be careful, as a blocked actuator can suddenly move uncontrollably, potentially causing injury. Disconnect and lock the pneumatic air supply and control signal before attempting to remove any blockage. Release any stored energy in the actuator, such as spring compression. Also, check the signal pressure and the signal pressure line for leaks. Ensure the signal pressure is connected to the correct diaphragm chamber, referring to the 'Installation' chapter. Finally, a defective diaphragm in the actuator could be the cause; in this case, you would need to replace the diaphragm.
