ATTENTION!
Avoid maladjustment of the controller due to an incorrect
pilot pressure or applied operating medium pressure.
▶ Run X.TUNE whenever the pilot pressure (= pneumatic aux-
iliary energy) is available during subsequent operation.
• Run the X.TUNE function preferably without operating medium
pressure to exclude interference caused by flow forces.
ATTENTION!
Breakage of the pneumatic connection pieces due to rota-
tional impact.
▶ When unscrewing and screwing in the transparent cap, do not
hold the actuator of the process valve but the basic housing.
