5. Interface angle adjustment


The angle can be adjusted between the positioner and the valve. If need to adjust the interface angle, rotate the main body casing clockwise or counter-clockwise in 180°range.


6. Additional software functions


  • Selection of the transfer characteristic between set-point value and stroke
  • Sealing function for position controller
  • Effective sense of direction between input signal and set-point value
  • Limit of the mechanical stroke range
  • Setting for control parameters
  • Safety position setting for the position controller
  • Configuration of signal level fault detection
  • Configuration of the outputs
  • Calibrating the control parameters
  • Setting for manual control rate
