8.3 Tuning Wizard
The positioner will automatically search for the mechanical valve travel limits and tune the
valve position PID control algorithm. Click Go to begin. This will take several minutes to
complete and will stroke the valve.
If this is not a first time setup of the valve, you may skip this step by clicking the Skip button.
WARNING
Before beginning the Auto or Manual 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.
Figure 8.3 Tuning Wizard
The air supply to the valve must be on and set to the correct pressure.
WARNING
Isolate the valve from the process and keep clear of moving parts before using Limit
Searching or Autotune.”
