If a double‐acting relay is used, you will be prompted to run the relay adjustment when auto calibration is selected.
Select Yes to adjust the relay. For additional information refer to Relay Adjustment on page 83.
If after completing the Setup Wizard the valve seems slightly unstable or unresponsive, you can improve operation by
selecting either Performance Tuner or Stabilize/Optimize.
Performance Tuner
Field Communicator Configure > Guided Setup > Performance Tuner (1‐1‐2)
Note
The Performance Tuner is available for instrument level AD, PD, and ODV.
WARNING
During performance tuning the valve may move, causing process fluid or pressure to be released. To avoid personal injury
and property damage caused by the release of process fluid or pressure, isolate the valve from the process and equalize
pressure on both sides of the valve or bleed off the process fluid.
The Performance Tuner is used to optimize digital valve controller tuning. It can be used with digital valve controllers
mounted on most sliding‐stem and rotary actuators, including Fisher and other manufacturers' products. Moreover,
because the Performance Tuner can detect internal instabilities before they become apparent in the travel response, it
can generally optimize tuning more effectively than manual tuning. Typically, the Performance Tuner takes 3 to 5
minutes to tune an instrument, although tuning instruments mounted on larger actuators may take longer.
Access Performance Tuner by selecting Performance Tuner from the Guided Setup menu. Follow the prompts on the
Field Communicator display to optimize digital valve controller tuning.
