7.3 Sequence of automatic initialization

3. Position feedback: You can adjust the range of position detection using the friction clutch
4. Adjust the positioner as per the respective actuator with the help of the initialization process
Types of initialization
You can initialize the positioner as follows:
● Automatic initialization:
The positioner also adjusts the control parameters as per the dynamic response of the actuator.
● Manual 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.

and by setting the parameters. If required, use the "PRST" parameter to cancel the
adjustment of the positioner on the actuator. The positioner is again in the "P manual mode"
after this process.
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 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.
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.
