Actuator and Valve Information
Field Communicator Setup & Diag > Detailed Setup > Actuator & Valve (1-2-5)
Follow the prompts on the Field Communicator to edit or view information in the following fields:
D Max Supply Press—Enter the maximum supply pressure in psi, bar, or kPa, depending on what was selected for
pressure units.
Note
If the actual measured pressure exceeds this setting by 25%, the pressure measurement will not be displayed.
D Actuator Style—Enter the actuator style, spring and diaphragm, piston double-acting without spring, piston
single-acting with spring, or piston double-acting with spring.
D Valve Style—Enter the valve style, rotary or sliding-stem
D Zero Control Signal—Identifies whether the valve is fully open or fully closed when the input is 0%. If you are unsure
how to set this parameter, disconnect the current source to the instrument. The resulting valve travel is the Zero
Control Signal. (With direct acting digital valve controllers, disconnecting the current source is the same as setting
the output pressure to zero.)
Setting Response
Field Communicator Setup & Diag > Detailed Setup > Response Control (1-2-6)
Follow the prompts on the Field Communicator to configure the following response control parameters:
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 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 2‐4 lists the proportional gain, velocity gain, and minor loop feedback gain values for preselected tuning sets.
