Transmission pin position Pin position of the positioner lever. See marking on the positioner lever.
Only for attachment to linear actuator acc. to NAMUR.
States:
Default (coldstart) value:
A/B
A
Travel/angle limit
lower
Lower limitation of valve travel/angle to the entered value. The characteristic is not adapted.
Range:
Default (coldstart) value:
–20.0 % to 99.9 % of the travel/angle range
0.0 %
Travel/angle limit
upper
Upper limitation of valve travel/angle to the entered value. The characteristic is not
adapted.
Range:
Default (coldstart) value:
0.0 % to 120.0 % of the travel/angle range
100.0 %
Travel range end Upper limitation of the effective working range (travel). For a non-linear characteristic, the
characteristic is adapted to the reduced valve travel.
Maximum value = rated travel.
If the "maximum range" has been initialized, the travel range is always related to the
entered nominal travel.
The working range may not be selected 1/4 less than the nominal angle.
Range:
Default (coldstart) value:
0.0 mm to 255.9 mm
15.0 mm
Travel range start
Lower limitation of the effective working range (travel). For a non-linear characteristic, the
characteristic is adapted to the reduced travel.
If the "maximum range" has been initialized, the travel range is always related to the
entered nominal travel.
The working range may not be selected 1/4 less than the nominal angle.
Range:
Default (coldstart) value:
0.0 mm to 255.9 mm
0.0 mm
Type of initialization Type of initialization related to the nominal or maximum range.
For initialization in the nominal range, only the range of the manipulated variable is
considered (e.g. globe valve with mechanical stop at one side). When the maximum range
is initialized, the maximum range is passed (e.g. three-way valve with mechanical stop at
both sides).
States:
Default (coldstart) value:
Nominal range / maximum range
Maximum range
Type of characteristic Unassigned text describing the user-defined characteristic
Length: 32 characters
Universal revision Revision number of the universal device description that the field device conforms to.
Valve id number Manufacturer identification of the valve delivered with the positioner.
Version Actuator with/without spring return.
States:
Default (coldstart) value:
Single acting with spring return / double acting without spring return.
Single acting.
