475: Debugging the Fisher locator; the actual opening is 45%, but the DCS shows 20%. What could be the reason? Does DCS need to be changed?

Does 475 calibrate the valve stroke?

Compare the current value shown in the 475 communication feedback with that of the ammeter on the serial port to see if they match

Connect 475 and check what the feedback is. If it is 25, then check the locator (such as the original feedback value, parameter settings, etc.); if it is 45, then check the current, the wiring, DCS parameter settings, and so on.

It seems this Fischer doesn’t have independent feedback.

Model 6200 is available; the feedback is passive and requires connection to a 24V power supply
