Operation and function
6.3.3. Running the Automatic Adjustment for X.TUNE
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!
NOTE!
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 subse-
quent operation.
• Run the X.TUNE function preferably without operating medium pressure to exclude interference caused by
flow forces.
