The hardware addressing is effective if an address <126 is set
with the address selection switches on the electronics module of
VEGABAR 82. Software addressing thus has no effect - only the set
hardware address applies.
The software addressing is only effective if address 126 or higher is
adjusted on the instrument with the address selection switches.
In the menu item "Sensor TAG" you edit a twelve digit measurement
loop designation label.
You can enter an unambiguous designation for the sensor, e.g. the
measurement loop name or the tank or product designation. In digital
systems and in the documentation of larger plants, a singular desig-
nation must be entered for exact identification of individual measuring
points.
The available digits comprise:
•
Letters from A … Z
•
Numbers from 0 … 9
•
Special characters +, -, /, -
In this menu item you activate/deactivate the slave for electronic dif-
ferential pressure and select the application.
If you have connected a slave sensor, you confirm this with "Activate".
If you have connected no slave sensor, you confirm this with "Deac-
tivate".
VEGABAR 82 can be used for process pressure and level measure-
ment. Default setting is process pressure measurement. The mode
can be changed in this adjustment menu.
The VEGABAR 82 in conjunction with a slave sensor can be used for
flow, differential pressure, density and interface measurement. The
default setting is differential pressure measurement. Switchover is
carried out in the adjustment menu.
Depending on the selected application, different subchapters in the
following adjustment steps are important. There you can find the
individual adjustment steps.
