Tuning
Methods for tuning the SVi1000:
Preset Tune
Preset tuning is done according to valve/actuator size. Figure 22 shows the graphic that appears
on the local user interface. As valve size increases values increase from 1 to 7 and 9 to F. 0 and
8 are reserved for auto tuning ATO and ATC valves, respectively.
Preset tuning becomes active immediately.

Presets; The fastest and easiest commissioning is to use a preset tuning for
the actuator in use ( "Preset Tune"). Using presets saves time as you do not
run Auto Tune.
Auto Tune: If desired, run Auto Tune ( "Auto Tune" on page 49).
PID Settings: The third method is to manually tune PID settings for fine
tuning, if desired. See the online help.
