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!
