Profibus PA address
In this window, you can assign a bus ad-
dress to the sensor in the field "Sensor ad-
dress". This function is only available if the
mini coding switch on the oscillator is set to
>126.
Reset
In this menu window, you can carry out two
different resets.
Standard reset (reset to default)
Adjustment 0 % - 0 pF
100 % - 3000 pF
Adjustment unit pF
Integration time 0 s
Linearisation linear
Sensor display scaled
Scaling 0.0 % 100 %
PA output volume
Failure mode last value
Sensor optimisationMode 1 (90°)
Total reset
With a total reset, all adjustments which can
be carried out via VVO or MINICOM are
reset.
This includes, e.g., the following data:
- electrode type
- Tag name
- offset correction
A total reset is necessary, e.g. if the oscilla-
tors are installed on another electrode.
Setup
Under the menu item "Configuration", you can
choose the following functions:
• Measuring system
• Measurement loop
• Program
The electrode is already preset at VEGA. The
measuring system must only be configured if
the oscillator is exchanged.
Measuring system
In this window, you can choose the respec-
tive electrode. You can find the electrode
type on the type plate of the instrument.
Choose the correct electrode from the list,
e.g. EL 21: 14 mm PTFE. In front of the listed
electrodes you see the electrode type
number. The number belonging to your ca-
pacitive electrode is stated on the type plate
(see also chapter "1.6 Type plate"). If your
electrode is not included in the list, choose
´not configured´. Push the Save button to
confirm the setting.
Information on the sensor ident number:
You do not have to modify the setting "VEGA
specific No.". Only if you want to make sure
the sensor can be replaced on the Profibus
by a sensor from another manufacturer do
you have to choose the option "Profile spe-
cific No.".
