MANUAL TUNE FUNCTIONS

Access to the manual

TUNE functions can be obtained by the selecting of X.TUNE in the main menu

and briefly pressing the MANUAL/AUTOMATIC key or aborting the countdown by releasing the MANU-
AL/AUTOMATIC key.

The following parameters, which are determined automatically during

X.TUNE , may be preset or

changed afterwards manually.

TUNE-END

- Return to main menu

TUNE-POS

- Preset end positions

The

AUTOTUNE function determines the end positions of the control armature automatically on the

basis of the physical stops. Certain armatures (e.g. continuously turning butterfly valves) possess no
physical end stop, so that the end positions must be manually preset by means of

TUNE-POS. An

immediately following

AUTOTUNE takes over the manual end position settings and continues with

setting the positioning system and optimization of the positioner.

NOTE

If a manual preset of the end positions with

TUNE-POS is necessary, it must be done

before execution of AUTOTUNE.
