Valve positioner failure
Thread Content
After ventilating the locator, the pressure gauge shows the air source pressure at its outlet; adjusting the zero point has no effect, and adjusting the input current also has no effect. I will try moving the range lever again this afternoon. I suspect it’s an amplifier issue; does anyone know a solution? Show the image below
