VEGABAR 86 • Secondary Device for electronic differential pressure
48048-EN-220817
7.1.3 Diagnostics
The respective min. and max. measured values for the differential
pressure and static pressure are stored in the sensor. In menu item "
Peak indicator, pressure
", both values are displayed.
In another window you can carry out a reset of the peak values
separately.
In this menu item you can simulate measured values. This allows the
signal path to be tested, e.g. through downstream indicating instru-
ments or the input card of the control system.
Select the requested simulation variable and set the requested value.
To deactivate the simulation, you have to push the
[ESC]
key and
confirm the message "
Deactivate simulation
" with the
[OK]
key.
Caution:
During simulation, the simulated value is output as 4 … 20 mA cur-
rent value and as digital HART signal. The status message within the
context of the asset management function is "
Maintenance
".
Note:
Without manual deactivation, the sensor terminates the simulation
automatically after 60 minutes.
7.1.4 Additional adjustments
In menu item "
Current output, variable
" you specify which measured
variable is output via the current output.
The following selection is possible depending on the selected ap-
plication:
•
Flow
•
Height - Interface
•
Density
•
Differential pressure
•
Static pressure
Peak indicator, pressure
Simulation 4 … 20 mA/
