Menu/parameter Value range Description
Actuator Type Linear, Rotary
Use this parameter to configure the configuration-,
parameterization instruction for the positioner for
operation on a linear actuator (sensor range ±30°) or on
a rotary actuator (sensor range ±45°). No mechanical
modifications to the positioner are required.
Linearization can be selected under the ‘Linear’
parameter in accordance with the mounting conditions:
Bolt Position
Bolt On Lever,
Bolt On Stem
For the linearization, when attaching to linear
actuators, a differentiation is made concerning the
mechanical part of the position transfer to which the
actuator bolt is permanently mounted.
-
Bolt On Lever (actuator bolt on the potentiometer
lever)
-
Bolt On Stem (actuator bolt on the valve stem)
Factory setting: Bolt On Lever
Vent Position
Position 0%, Position
100%
Use this parameter to specify which position is to be
shown in the display when output 1 of the positioner is
completely vented.
Set point
SP Range Min.
SP Range Max.
SP Filter
SP Ramp Up
SP Ramp Down
SP Charact. Curve
SP Direction
The parameters for the set point are set in this
parameter group.
Range Settings
Valve Rng Calib.
Upper Valve Rng
Lower Valve Rng
The valve end positions and the working range in which
the valve is to be controlled are set in this parameter
group.
Note:
If the work area is limited, the switching points of the
digital feedback opposite the valve area which had
possibly been previously adjusted will shift.
End Stop Behav.
Tight Shut 0%
Control at 0%
Dead Angle 0%
Tight Shut 100%
Control at 100%
Dead Angle 100%
The end position behavior is set in this parameter
group.
Recalc. Position Off, On
Use this parameter to define whether the position
indicator and Analogue position feedback display the
valve position (Direct) or the valve flow (Recalculated).
