VEGA VEGASON 65 Foundation Fieldbus - Manual (Page 32)

6.4 Setup procedure
A fter VEGASON 65 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:
l I nternal check of the electronics
l I ndication of the instrument type, the firmware as well as the
sensor TAGs (sensor designation)
l S tatus byte goes briefly to fault value
T hen the current measured value will be displayed and the
corresponding digital output signal will be outputted to the cable. 1)
A
s VEGASON 65 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.
T he 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.
T he 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.
I n the main menu item "Basic adjustment", the individual submenu
items should be selected one after the other and provided with the
correct parameter values.
S tart your parameter adjustment with the following menu items of the
