Description
Use this parameter to configure the positioner for operation on a linear actuator (sensor
range +/-30°) or on a part-turn actuator (sensor range +/-45°). No mechanical modifications to
the positioner are required.
IMPORTANT (NOTE)
After changing the actuator type, it is recommended that you run Autoadjust to
prevent linearity errors.
Use this parameter to specify which position is to be shown in the display when output 1 of the
positioner is completely vented.
The shut-off value is a percentage of the working range from which the 0 % position is
approached. Once the specified position limit value is reached, the actuator moves directly into
the 0 % end position.
Use this parameter to set the end position behavior. If the parameter is activated, the 0 % position
is controlled. Otherwise, the actuator moves into the 0 % mechanical end position.
The shut-off value is a percentage of the working range from which the 100 % position is
approached. Once the specified position limit value is reached, the actuator moves directly into
the 100 % end position.
Use this parameter to set the end position behavior. If the parameter is activated, the 100 %
position is controlled. Otherwise, the actuator moves into the 100 % mechanical end position.
Use this parameter to define the mode or scope of the Autoadjust function.
Full – Full Autoadjust
Controller – Only determine control parameters
Zero – Only determine the 0 % position
Valve Range – Only determine limit stops
Locked – Autoadjust locked
The following values are determined during Autoadjust:
— Actuator's direction of action
— Reset spring's direction of action
— Actuator / valve travel
— Stroke time for both directions
— Control parameters
— Offset for the I/P module
— Actuator / valve stiction
— Actuator / valve dynamic friction
