3. Perform Setup Wizard
Use the
Full Wizard
tab to configure the basic setup for the SVi1000. This tab gives you the
opportunity to configure the following:
Device Information
: Shown in Figure 9 configures nameplate data.
Find Stops
:
Find Stops
or
Manual Find Stops
.
Auto Tune
: PID parameters
.
Position
:
Position Fault Limits
.
Step Test
: Run an initial step test.
Ramp Test
: Run an initial ramp test.
Change Device Mode
: Set the device mode on completion of assigned tasks.
WARNING
This procedure moves the valve.
Before beginning the Find Stops range calibration, confirm that
the valve is isolated from the process. This procedure exhausts
and then fills the valve actuator to supply pressure and therefore
strokes the valve over its full range.
Supply pressure MUST NOT exceed the actuator pressure rating
marked on the actuator. Positioner supply pressure MUST BE at
least 5 psi higher than the upper spring range of the valve.
CAUTION
Procedures (e.g. Find Stops, Auto Tune, Step Test or Ramp Test)
should
NOT be
invoked if the ValVue sequencer is running. For
information on the sequencer, see ValVue 3’s online help.
Do not Auto Tune if manual tuning has been used. Auto Tune
creates new parameters that override the manual tuning
parameters.
For a successful Auto Tune process, the supply pressure must be
at least 5 PSI (34.5 kPa) above the spring range.
