Travel Tuning
WARNING
Changes to the tuning set may cause the valve/actuator assembly to stroke. To avoid personal injury and property damage
caused by moving parts, keep hands, tools, and other objects away from the valve/actuator assembly.
D Travel Tuning Set
There are eleven 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.
Table 3‐3 lists the proportional gain, velocity gain and minor loop feedback gain values for preselected tuning sets.

In addition, you can specify Expert tuning and individually set the proportional gain, velocity gain, and minor loop
feedback gain. Individually setting or changing any tuning parameter or running the Performance Tuner or Stabilize
Optimize routine will automatically change the tuning set to X (expert).
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 manual Expert tuning.
Table 3‐4 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, you may have to select either
a higher or lower tuning set to get the desired response. You can use the Performance Tuner to optimize tuning.
