Stroke Rate Limits
The Stroke Rate Limits area displays the maximum rate of travel in the opening and closing
directions. Limiting the rate of travel can be helpful to prevent surging process flow.
Positioner Gains
Positioner gains are set atomically during the Quick-Cal process and typically do not
require modification. Change these values will affect responsiveness.
Opening values will affect the responsiveness in the opening direction.
Closing values will affect the responsiveness in the closing direction.
Positioner Gain is the easiest way to adjust the responsiveness. This may only be adjusted
at the positioner. Use the Selectable GAIN Switch to adjust the gain at any time during
operation. This adjustment takes effect immediately. For faster response select settings
above “E” (F-J). For more stable response, select settings below “E” (B-D). To perform a
Quick-Cal without affecting custom gain settings, select "A".
Stroke Time from Calibration
The Stroke Time from Calibration area displays the stroke time in seconds measured
during quick calibration.
