Pressure Tuning Set

WARNING
Changes to the tuning set may cause the valve/actuator assembly to stroke. To avoid personal injury or property damage
caused by moving parts, keep hands, tools, and other objects away from the valve/actuator assembly.
There are twelve Pressure Tuning Sets to choose from. Each tuning set provides a preselected value for the digital valve
controller gain settings.
Tuning set B provides the slowest response and M provides the fastest response. Tuning set B is appropriate for
controlling a pneumatic positioner. Table 3‐4 lists the proportional gain, pressure integrator gain and minor loop
feedback gain values for preselected tuning sets.
In addition, you can specify Expert tuning and individually set the pressure proportional gain, pressure integrator gain,
and pressure minor loop feedback gain. Individually setting or changing any tuning parameter will automatically
change the tuning set to X (expert).

Note
Use Expert tuning only if standard tuning has not achieved the desired results.
Out Block Selection
Out Block Selection defines which output function block, Analog or Discrete, will control the setpoint of the valve.
Note
Select the AO function block if throttling control is required. Select the DO function block for on/off connectivity.
