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
After VEGASON 61 is connected to voltage supply or after voltage
recurrence, the instrument carries out a self-check for approx. 30
seconds. The following steps are carried out:
•
Internal check of the electronics
•
Indication of the instrument type, the firmware as well as the sen-
sor TAGs (sensor designation)
•
Status byte goes briefly to fault value
Then the current measured value will be displayed and the corre-
sponding digital output signal will be outputted to the cable. 2)
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.

already carried out, e.g. default setting.
