5.4 Parameter
Types of initialization
You can initialize the positioner as follows:
● Automatic initialization:
during automatic initialization, the positioner determines the following one after the other:
– The direction of action
– The actuator travel and angle of rotation
– The travel time of the actuator
The positioner also adjusts the control parameters as per the dynamic response of the actuator.
● Manual initialization:
the actuator travel and the angle of rotation of the actuator are set manually. The remaining
parameters are automatically determined. This function is useful for valves which are lined,
for example, with PTFE.
● Copying the initialization data when replacing a positioner:
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.
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 digital input to protect the configured settings
against accidental adjustment.

5.4 Parameter
Introduction
Parameters 1 to 5 are the same for all versions of the positioner. These parameters are used
to adjust the positioner to the actuator. Normally, setting these parameters is sufficient to be
able to operate the positioner on an actuator.
If you want to get to know all details of the positioner, gradually try out the effects of the
remaining parameters by systematic testing.
Note
Factory-set parameter values are printed in bold in the following table.
