38 Capacitive electrodes EK - Profibus PA
Profibus PA address
In this window, you can assign a bus
address to the sensor in the field "Sensor
address". This function is only available if the
mini coding switch on the oscillator is set to
126 or higher.
Reset
In this menu window, you can carry out two
different resets.
Standard reset (Reset on 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
Interference mode last value
Sensor optimisation mode 1 (90°)
Total reset
In case of 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
oscillators 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 reconfigured
if the oscillator is exchanged.
Measuring system
In this window, you can choose the
respective electrode. You can find the
electrode type on the type plate of the
instrument.
Choose the correct electrode from the list,
e.g. EK 21: 14 mm PTFE. In front of the listed
electrodes you see the electrode type
number. The number belonging to your
capacitive 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
specific No.".
