What to do if the actuator of my Samson Valve Positioner does not move?
If the actuator of your Samson Valve Positioner doesn't move during initialization, start by verifying the air supply and ensuring it is adequate. Also, inspect the positioner mounting for any obstructions. Finally, check the milliamp (mA) input signal. After these checks, re-initialize the positioner.
How to fix zero error on Samson Valve Positioners?
If your Samson Valve Positioner shows a zero error, it means the zero point has shifted more than 5% since initialization, possibly due to valve seat trim wear. Check the valve and positioner attachment, as well as the supply pressure. If the mounting is correct, recalibrate the zero point using Code P23 (see the 'Start-up and configuration' section), and clear the error code (see section 9.1.1).
What to do if travel is not achieved during initialization of Samson Valve Positioners?
If your Samson Valve Positioner's travel isn't achieved during initialization, it could be due to low supply pressure, actuator leaks, incorrect travel settings, or an activated pressure limit function. Check the supply air, positioner mounting, lever, pin position, and settings. Then, re-initialize the positioner.
Why is the transit time too short during initialization of my Samson Valve Positioner?
If the transit time is too short during the initialization of your Samson Valve Positioner, it means the actuator transit times detected are too short, making optimal tuning impossible. Inspect the piping and re-initialize the positioner. If needed, use a screw restriction or reduce the gain K.
What to do if displayed and INIT values are not identical on Samson Valve Positioners?
If the displayed and INIT values on your Samson Valve Positioner aren't identical, it's because the parameters (Code P3, P4, or P5) were changed after initialization. To resolve this, either reset the parameters or re-initialize the positioner.
Why is standstill detection not possible during initialization of Samson Valve Positioners?
If standstill detection is not possible during the initialization of your Samson Valve Positioner, it may be due to variations in supply pressure or incorrect mounting. Check the supply air and positioner mounting. Then, re-initialize the positioner.
Why does the actuator move in the wrong direction on my Samson Valve Positioner?
If your Samson Valve Positioner's actuator moves in the wrong direction, check the direction of action (Code P8), the characteristic setting, the piping, and the configuration of the mounting parts.
How to fix K setting P initialization error on Samson Valve Positioners?
If the gain setting P is causing an initialization error on your Samson Valve Positioner, it means the gain is too high. Limit the gain K (Code P9), re-initialize the P positioner, and possibly use a screw restriction.
What causes the travel signal to be at the lower or upper limit on Samson Valve Positioners?
If the travel signal is at the lower or upper limit on your Samson Valve Positioner, it could be due to the wrong pin position, lever, or attachment direction when using NAMUR attachment. Reset the error code (see section 9.1.1), check the positioner mounting, and re-initialize the positioner.
Why does the actuator move too slowly on my Samson Valve Positioner?
If your Samson Valve Positioner's actuator moves too slowly, examine the supply pressure, the cross-section of the piping and screw fittings, and the configuration of the mounting parts.
