Start-up and settings
During the initialization procedure, the
positioner checks whether the control valve
can move through the indicated nominal
range (travel or angle) without collision.
In case of a positive result, the indicated
nominal range is adopted with the limits of
lower x-range and upper x-range values as
the operating range.
Note!
The maximum possible travel must always
be greater than the nominal travel entered.
If this is not the case, the initialization is
canceled (error indication Code 52) be-
cause the nominal travel is not achieved.

The initialization procedure may
take several minutes, depending on
the actuator size, as the valve moves
through its entire travel/angle of ro-
tation range.
Positioners with EXPERT
tions automatically start plotting the refer-
ence graphs after the initialization process
has been completed. See note at the bottom
of page 46.
