As initialization has not been carried out

the display.
These alarms do not influence the
positioner’s readiness for operation.

cillate in automatic operating mode, the
parameters K
P
and T
V
must be slightly
corrected. Proceed as follows:
Set T

If the positioner still oscillates, the gain
K
P
(Code 17) must be decreased until the
positioner shows a stable behavior.
