If you suspect an air leak in your Siemens Valve Positioners, verify that the "PNEUM" parameter is set correctly. You should also perform a leak test and check the pneumatic fittings, air lines, and actuator for any issues.
What to do if Siemens Valve Positioners have insufficient supply air?
If you're experiencing insufficient supply air with your Siemens Valve Positioners, open the restrictor completely and/or set the supply air to the highest permissible value.
How to reduce stiction in Siemens Valve Positioners?
To address stiction in Siemens Valve Positioners, set the DeadBand value to "Auto".
What to do if Siemens Valve Positioners have too much restriction?
If your Siemens Valve Positioners have too much restriction, open the restrictor(s) by turning counter-clockwise until the factory position is reached.
What to do if Siemens Valve Positioners have high vibration?
If you're experiencing high vibration with your Siemens Valve Positioners, and you cannot avoid it, consider using Non-Contacting technology.
What to check if Siemens Valve Positioners don't fully close or open?
If the valve on your Siemens Valve Positioners does not fully close or open, set Parameter YCLS to "Up do" (Tight Closing Up and Down).
What to do if Siemens Valve Positioners have erratic feedback?
To troubleshoot erratic feedback in Siemens Valve Positioners, use an independent power source and current meter to isolate the field wiring by powering up the feedback card locally. If the erratic feedback disappears, the issue lies with the field wiring or the original power source.
What to do if Siemens Valve Positioners have a mechanical blockage?
If you suspect a mechanical blockage in your Siemens Valve Positioners, check for any obstructions preventing valve movement.
How to troubleshoot erratic input signal on Siemens Valve Positioners?
To troubleshoot an erratic input signal on your Siemens Valve Positioners, first verify that the unit is in Automatic mode. If it is, press and hold all three buttons for at least 5 seconds.
What to do if Siemens Valve Positioners have loose or worn linkage?
If you notice loose or worn linkage in your Siemens Valve Positioners, and a mechanical component does not move with the other components, secure the component with the supplied hardware.
