Step 4: Autotune
The SVi1000 has a built in positioning Autotune feature. When setting up the valve controller,
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 user interface, a handheld
communicator loaded with the device driver (DD), a control system loaded with the DD or
SVi1000 software. However, it cannot be fully done remotely, as you must use the local user
interface Configuration Selection Switch.
To autotune the SVi1000 with the Setup Wizard:
1. Move the Configuration Selection Switch on the unit to:
0 for and ATO valve.
8 for an ATC valve.
2. Click the Autotune checkbox.
3. Enter a Supply Pressure.
