Page 10: Installation Steps
3.2.1 Installation Steps 1. Proper bracket must be made in order to adapt the positioner on the actuator yoke. Please consider following important points when a bracket is being designed. Positioner’s feedback lever must be parallel to the ground at 50% of the valve stroke. ... - Page 11 7. Check if feedback lever is parallel to the ground at 50% of the valve stroke. If it is not parallel, adjust the bracket or feedback link bar to make parallel. Improper installation may cause poor linearity and may create unnecessary hunting during the operation. 8.

Page 20: Auto Calibration (Auto Cal)
6.3.1 Auto Calibration (AUTO CAL) Auto Calibration (AUTO CAL) automatically calibrates the positioner. “AUTO CAL” process takes about 2~3 minutes, and the duration of the process varies upon the size of the actuator. There are 3 types of AUTO CAL. Zero Point End Point KP, KI, KD... -
