VEGA VEGASON 66 4 … 20 mA_HART four-wire - Manual (Page 32)

6.4 Setup procedure
In HART-Multidrop mode (several sensors on one input) the
address must be set before continuing with the parameter
adjustment. You will find a detailed description in the
Operating instructions manual "Indicating and adjustment
module" or in the online help of PACTware™ or DTM.

As VEGASON 66 is a distance measuring instrument, the
distance from the sensor to the product surface is measured.
To have the real product level displayed, an allocation of the
measured distance to the percentage height must be made. To
carry out this adjustment, the distance is entered with full and
empty vessel. If these values are not known, an adjustment
with the distance values, e.g. 10 % and 90 % is also possible.
Starting point for these distance specifications is always the
the lower side of the flange (flange version, for all other
versions the lower side of the transducer.
The actual level is then calculated on the basis of these
entered values. At the same time, the operating range of the
sensor is limited from maximum range to the requested range.
The real product level during this adjustment is not important,
because the min./max. adjustment is always carried out
without changing the product level. These settings can be
made ahead of time without the instrument having to be
installed.
In the main menu item "Basic adjustment", the individual
submenu items should be selected one after the other and
provided with the correct parameter values.
Start your parameter adjustment with the following menu items
of the basic adjustment:
Proceed as follows:
1 Move from the measured value display to the main menu
by pushing [OK].
