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 binary input to protect the configured settings against accidental
adjustment.
5.3 Sequence of automatic initialization
