MANUAL TUNE - FUNCTIONS
Access to the manual TUNE functions is obtained by selection X.TUNE in the main menu and briefly
pressing the MANUAL/AUTOMATIC key, or on abortion of countdown, by releasing the MANUAL/
AUTOMATIC key.
The following parameters, which are automatically determined during X.TUNE, may be manually
present or adjusted afterwards.
TUNE-END - Return to main menu
TUNE-POS - Present end position
The AUTOTUNE function determines the end positions of the control armature from the physically stops.
Certain armatures (e.g. rotating vanes) have no physically stops, so that the end positions must be
manually present using
TUNE-POS. When executed immediately afterwards, AUTOTUNE assumes the
manual end settings and continues with the setting of the positioning system and optimization of the
positioner.
NOTE If manual presetting of the end positions by means of TUNE-POS is necessary, it must be
done before execution of AUTOTUNE.
ATTENTION!
During execution of the AUTOTUNE function, the valve moves on its own away from its
current position. For this reason, never execute AUTOTUNE while the process is
running!
