ating mode!
The current valve position is indicated in %.
Note: If the positioner shows a tendency to
oscillate in automatic operating mode, the
parameters K
P
and T
V
must be slightly cor

rected. Proceed as follows:
Set T
V
to 4 (Code 18).
If the positioner still oscillates, the gain K
P
(Code 17) must be decreased until the
positioner shows a stable behavior.
Zero point calibration
Finally, if process operations allow it, the
zero point must be adjusted according to
section 5.8 on page 71.
CAUTION!
The positioner automatically moves to zero
point.
