VEGA VEGASON 66 Profibus PA - Manual (Page 32)

6.4 Setup procedure
After VEGASON 66 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
Internal check of the electronics
l
Indication of the instrument type, the firmware as well as
the sensor TAGs (sensor designation)
l
Status byte goes briefly to fault value
Then the current measured value will be displayed and the
corresponding digital output signal will be outputted to the
cable.

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 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:

tings already carried out, e.g. default setting.
