Auto Tune
The SVI II ESD has a built-in positioning Auto tune feature. When setting up the PST controller
on a valve, this feature automatically computes the optimal parameters for the positioning
algorithm. This feature does not require valve specific parameters in order to complete
successfully.
The Autotune feature can be launched using the local pushbuttons, a handheld
communicator loaded with the device driver (DD), a control system loaded with the DD or
ESDVue software. ESDVue must be in Setup mode to perform Auto Tune. (See “Change
Mode” on page 83)
To start the Auto Tune function:
1. Click Auto Tune (Figure 137).
