7 Set up with the display and adjustment module
VEGAFLEX 82 • 4 … 20 mA/HART two-wire
44222-EN-130823
The default setting is min. current 3.8 mA and max. current 20.5 mA.
If a supplementary electronics with a second current output is im-
plemented in the instrument, then you can adjust the second current
output separately.
In menu item"Current output 2" you specify which measured value
the second current output refers to.
The second current output cannot be used as an output in the sense
of a safety-instrumented application (SIL).
The procedure corresponds to the previous settings of the standard
current output. See "Setup - Current output".
Since the HART variables are very extensive, the indication was
divided into two menu items.
In the menu "HART variables 1" you can have the first HART value PV
(primary value) and the second HART value SV (secondary value) of
the sensor displayed.
The values cannot be changed in the display and adjustment module.
To change these values, you have to use the adjustment software
PACTware.
HART functions are not relevant for SIL applications.
In the menu "HART variables 2" you can have the third HART value
TV (third value) and the fourth HART value QV (quarter value) of the
sensor displayed.
The values cannot be changed in the display and adjustment module.
To change these values, you have to use the adjustment software
PACTware.
HART functions are not relevant for SIL applications.
The following circumstances cause interfering reflections and can
influence the measurement:
•
High sockets
•
Vessel installations such as struts
•
Deflectors, etc.
