  Valve positioner commissioning steps:
  1. Positioner panel settings:
  2. Internal wiring (4 wires): feedback and command lines.
  3. Important parameter switching method before commissioning:
  (1) Switch between local and remote operation. Press and hold the MODE button, then press the ↑ or ↓ button to toggle between the two modes.
  (2) Enter 1.1 (Remote Control) and 1.2 (Local Control) using the method described in (1).
  (3) To perform a quick open, first press and hold the ↑ key, then press the ↓ key; to perform a quick close, first press and hold the ↓ key, then press and hold the ↑ key, in order to complete the operation.
  (4) Enter 1.3 using the method described in (1), and the word SENS-POS will appear, indicating that after adjusting the positioner, the linkage and the rear knob arc remain within a symmetrical range.
  4. Debugging Steps
  (1) P1.0: Press the ↑ and ↓ keys simultaneously, then press the “ENTER” key. The word “LINEAR” will appear, allowing you to adjust the angular stroke and linear stroke.
  (2) P1.1: Press and hold the MODE key, then press the ↑ and ↓ keys to enter the P1.1 menu. Continuously press the ENTER key for 3 seconds; once the panel displays a countdown of 0, release the key, and self-tuning will begin. The process will continue until the word “COMPLETE” appears.
  (3) P1.4: When exiting (EXIT), “Save” and “Do Not Save” will be displayed. Press and hold the “ENTER” key for 3 seconds to save the debugging settings; if you do not wish to save, simply press the up arrow key to return to the “Cancel” option, then press and hold the “ENTER” key for 3 seconds to exit.
  (4) When the word “REVERSE” appears on P2.3, it indicates the direct or reverse action of the control valve and positioner.
  (5) When the CW/CCW word appears in P3.2, it adjusts the direct and reverse action of the DCS and the local positioner commands.
  (6) The word “EXIT” appears at P3.3, meaning “exit.”
  (7) If the word “DIGEET” appears on P8.2, the adjustment pertains to the direct and reverse action of the DCS and the field positioner feedback.
  The above parameters are critical for the debugging procedure; please refer to the user manual for details.
