X.TUNE -

Automatic calibration of the position controller

The X.TUNE function must be run for a function check of the positioner to adjust to specific local
features.
WARNING!
While the X.TUNE function is running, the valve automatically moves from its current position.
▶ Never run X.TUNE while a process is running.
▶ Take appropriate measures to prevent the system / positioner from being unintentionally actuated.
ATTENTION!
Avoid maladjustment of the controller due to an incorrect compressed air supply or applied operating
medium pressure.
▶ Run X.TUNE whenever the compressed air supply (= pneumatic auxiliary energy) is available during
subsequent operation.
▶ Run the X.TUNE function preferably without operating medium pressure to exclude interference caused
by flow forces.
To run X.TUNE, the positioner must be in the AUTOMATIC operating state (DIP switch 4 = OFF).
