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.
