<p>The regulating organ (1) has a pneumatic actuator (6) and a position regulator (7), which adjusts a control signal (Y) of the organ till a regulation deviation comes to zero. The control signal is provided by a process controller (3). A function (19) of the organ is programmed with logic (14) in the control. The function of the organ is brought into a domain by utilization of full capacity of the position regulator when the organ is in a seal closed position and the regulation deviation becomes negative. The function is set during stopping of fluid (4).</p> |
