NOINI (P-Manual Mode) Troubleshooting
This document can be considered as a ‘catch-all’ procedure that can uncover all issues that
will prevent successful PS2 initialization. For mechanical installation of positioner to actuator,
refer to the specific mounting kit instructions.
Note
This procedure will move the valve throughout the entire valve stroke. Therefore, valve
should be bypa
ssed so movements do not adversely affect process.
Activate NOINI Mode (if not active already):

– Press and release
button until parameter "4.INITA" is reached.
– Once at parameter "4.INITA", press and hold
button until display changes to: "no".
– Press and hold
button to exit configuration mode.
Move the Valve:
While the display is flashing "NOINI" the valve can be moved with the or buttons.
