Figure 62: Operating structure X.CONTROL
dBnd insensitivity range (dead band) of the position controller
Input the dead band as %, relating to the scaled stroke range;
i.e. X.LIMIT Max - X.LIMIT Min (see Auxiliary function X.LIMIT).
This function causes the controller to respond from a specific control difference only. This function
protects the solenoid valves in the positioner and the pneumatic actuator.
If the auxiliary function X.CONTROL is in the main menu while X.TUNE (Autotune of the position controller)
is running, the dead band DBND is determined automatically depending on the friction behaviour of the
actuator. The value determined in this way is an approximate value. You can re-adjust it manually.

if the sub-menu is left by pressing the selection key on the left (ESC), the value remains unchanged.
