Start-up and configuration
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).
Start initialization:
Î
Enable configuration (section 7.1).
1. Turn until Code P22 appears.
2. Press and hold for 3 s (reading: 3 ... 2 ... 1 ).
Î
Initialization starts. P22 and INIT blink during initialization. The
time required for the initialization procedure depends on the actu-
ator transit time, which means that initialization can take a few
minutes.
%
After a successful initialization, Code P0 appears on the display and
the positioner changes to closed-loop operation indicated by the
closed-loop operation icon.
Initialization is canceled and the fault indication icon appears
when initialization fails.
Canceling initialization
The initialization can be canceled:
