D Tuning Set—There are twelve tuning sets to choose from. Each tuning set provides a preselected value for the digital
valve controller gain settings. Tuning set C provides the slowest response and M provides the fastest response. For
smaller actuators use tuning set C or D. For larger actuators using tuning set F or G. Table 3‐3 lists the values for
preselected tuning sets.
Note
Tuning set B is only available in Pressure Control Mode.

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.
In addition, you can select Expert, which allows you to individually set the proportional gain, velocity gain, and minor
loop feedback gain for travel tuning and pressure proportional gain, pressure integrator gain, and pressure minor loop
feedback gain for pressure tuning. Refer to page 48 for additional information on travel tuning and page 50 for
pressure tuning.
Note
Use Expert tuning only if standard tuning has not achieved the desired results.
Stabilize/Optimize or Performance Tuner may be used to achieve the desired results more rapidly than expert tuning.
Table 3‐2 provides tuning set selection guidelines for Fisher and Baumann actuators. These tuning sets are only
recommended starting points. After you finish setting up and calibrating the instrument, use Stabilize/Optimize to
adjust the tuning set to get the desired response.
