Tip
For normal operation, simply start initialization over Code P22 after mounting the positioner
on the valve, checking the fail-safe position (P3), to ensure that the positioner works proper-
ly. The positioner only works with its default settings.
The type and extent of self-adaptation depends on the preset parameters. MAX applies as
the default setting for the nominal range (Code P5). During the initialization process, the po-
sitioner determines the total travel range or rotational range of the valve (from the CLOSED
position to the opposite end position).

2. Press
Î Initialization starts. P22 and INIT blink during initialization. The
time required for the initialization procedure depends on the actu-

minutes.
After a successful initialization, Code P0 appears on the display and
the positioner changes to closed-loop operation indicated by the
