SITRANS LU HART
17.1 SitrLuHA
The minimum peak gradient value is displayed if the gradient monitoring function for negative
changes is enabled (GradHDnEn = 1)
(6) Resetting of peak values of the gradient
Using these buttons you can reset the maximum or minimum peak value of the gradient (output
parameters PV_GradPP0 and PV_GradNP0).
The button is displayed if the gradient monitoring function for positive (GradHUpEn = 1) or
negative (GradHDnEn = 1) changes is enabled.
(7), (8) Display of HART variables including signal status
This area provides information on the current process values of the HART variables with the
corresponding signal status. The name of the configured measured value is displayed
depending on the PV_Meas1..2 variable, in this case "Level", "Space", "Distance",
"Temperature", "Volume", "Volume flow", and "Custom". TV and QV are not supported by
Sitrans Probe LU240.
(11) Display of fill time and empty time
Fill time and empty time are shown in this area if Feature bit 6 (Activate calculation of fill time/
empty time) is enabled.
With a positive gradient value, a value is calculated for the fill time. With a negative gradient
value, a value is calculated for the empty time.
The calculated times are only shown if the gradient value is outside the deadband
(DeadTFiEm).
(12) and (13) Display of auxiliary values
You can use this area to display two auxiliary values that have been configured in the
Engineering System (ES). You can find more information on this in the section "Opening
additional faceplates" in the APL Online Help.
(14) Button for switching to the standard view of any faceplate
Use this button for the standard view of a block configured in the Engineering System (ES). The
visibility of this navigation button depends on the configuration in the engineering system (ES).
You can find more information on this in the section "Opening additional faceplates" in the APL
documentation.
