Chapter 3. Operation
3-1. Auto-setup
Auto-setup is a unique program for automatically making various positioner adjustments.
After installing your SVX, auto-setup should be performed. The built-in zero and span
adjustment switches on the SVX provides non-interactive closed and open valve position
setting.
There are three ways to perform Auto-Setup.
„
Using the Switch.
„
Using the Field Communication Software (model CFS100)
Refer to the operation manual for Smart Valve Positioner (CM2-CFS100-2010 ).
„
Using HART Communicator
Refer to "5-1-2: Using a HART Communicator" on page 55.
Note) After auto-setup has completed, verify valve operation by varying the input signal.
After auto-setup, the SVX is calibrated to the fully shut (zero) and fully open (span) values
of the valve. If the valve is not achieving the proper relationship between its travel and the
control signal of the SVX, then adjust zero or span manually.
