9.2 Sequence of automatic initialization

● Copying the initialization data when replacing a positioner:
You have to define a few parameters for the positioner before initialization. Owing to the
preset values, you cannot adjust further parameters for initialization.
You can use a suitably configured and activated binary input to protect the configured
settings against accidental adjustment.
9.2 Sequence of automatic initialization
The automatic initialization takes place in the following phases:
Automatic initialization phase

RUN1
RUN2
RUN3
RUN4
RUN5
End
The following structured charts describe the sequence of initialization. The "Up/Down"
names indicate the direction of action of actuators.

the initialization data of a positioner can be read and copied into another positioner. A
defective device can thus be replaced without interrupting an ongoing process through
initialization.
