The sensor is adjusted via the four keys of the display and adjust-

ment module. The LC display indicates the individual menu items. The

functions of the individual keys are shown in the above illustration.

Approx. 10 minutes after the last pressing of a key, an automatic reset

to measured value indication is triggered. Any values not confirmed

with [OK] will not be saved.

6.4 Setup steps

Before starting the actual parameter adjustment of a Profibus PA

sensor, the address setting must first be carried out. You will find a

detailed description in the operating instructions manual of the display

and adjustment module or in the online help of PACTware or DTM.

As VEGASON 61 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 lower side of the flange, with 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, be-

cause the min./max. adjustment is always carried out without chang-

ing 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].
