3.2 Principle of
operation
VEGAWELL 72 is used for level and gauge measurement in
wells, basins and atmospherically open vessels particularly in
the water/waste water industry as well as in the shipbuilding
industry.
The
1)
actual sensor element is the CERTEC
®
measuring cell
with rugged ceramic diaphragm. The hydrostatic pressure
causes a capacitance change in the measuring cell via the
ceramic diaphragm. This change is converted into an
appropriate output signal.
Two-wire electronics 4 … 20 mA/HART for power supply and
measured value transmission over the same cable.
The supply voltage range can differ depending on the
instrument version.
Data for power supply are specified in chapter "Technical
data".
3.3 Operation
VEGAWELL 72 - 4 … 20 mA/HART can be adjusted with
different adjustment media:
l with external adjustment/indication VEGADIS 12
l an adjustment software according to FDT/DTM stan
e.g. PACTware and PC
l With a HART handheld
The
type of adjustment and the adjustment options depend on
the selected adjustment component. The entered parameters
are generally saved in the respective sensor, when adjusting
with PACTware™ and PC optionally also in the PC.

Always keep in mind the following safety instructions:
l Connect only in the complete absence of line voltage
l If overvoltage surges are expected, overvoltage arresters
should
be installed
Tip:
We recommend
l B63-48 (use in plastic housing
l ÜSB 62-36G.X (use in a separate housing)
the following VEGA overvoltage arresters:
of VEGAWELL 72)
In hazardous areas you should take note of the appropriate
regulations, conformity
and type approval certificates of the
sensors and power supply units.
Power supply and current signal are carried on the same twowire cable. The voltage supply range can differ depending on
the instrument version.
Data for power supply are specified in chapter "Technical
data".
Provide a reliable separation between the supply circuit and
the mains circuits according to DIN VDE 0106 part 101.
VEGA power supply units VEGATRENN 149AEx, VEGASTAB
690, VEGADIS 371 as well as all VEGAMETs meet this
requirement. When using one of these instruments, protection
class III is ensured for VEGAWELL 72.
Bear in mind the following factors regarding supply voltage:
l Outpu
t voltage of the power supply unit can be lower under
nominal load (with a
sensor current of 20.5 mA or 22 mA in
case of fault message)
l Influence
of additional instruments in the circuit (see load
values in chapter "Technical data")
The instrument is connected with standard two-wire cable
without screen. If electromagnetic interference is expected
which is above the test values of EN 61326 for industrial areas,
screened cable should be used.

5 Connecting to power supply
Use cable with round cross-section. A cable outer
diameter of
5 … 9 mm (0.2 … 0.35 in) ensures the seal effect of the cable
gland. If you are using cable with other diameter or crosssection, you have to exchange the seal or use a suitable cable
gland.
We generally recommend the use of screened cable for HART
multidrop mode.

connected directly to the internal ground terminal. The ground
terminal outside
on the housing must be connected to the
potential equalisation.
If potential equalisation currents are expected, the connection
on the processing side must be made via a ceramic capacitor
(e. g. 1 nF, 1500 V). The low frequency potential equalisation
currents are thus suppressed, but the protective effect against
high frequency interference signals remains.

The adjustment data are effective, the output current 4 … 20 mA
corresponds to the actual level.
Information:
The corresponding current
values must be calculated and set
respectively for adjustment with part fillings or emptyings.
Example: For a part emptying of 25 %, a current of 4 mA +
4 mA = 8 mA must be set, for a part filling of 75 %, a current of
4 mA + 12 mA = 16 mA. VEGAWELL 72 then calculates the
values for full and empty.
Adjustment st eps, integration time
Adjustment st eps, scaling
Proceed as follows for the adjustment of the integration time
with VEGADIS 12:
1 Open housing cover
2 Set rotary switch to "ti"
3 Make sure that the integration time is set to 0 sec by
pressing the [-] key 10 times.
4 For every 1 sec. requested integration time, push the [+]
key once.
5 The integration time is the time required by the output
current signal to reach 90 % of the actual height after a
sudden level change.
6 Set rotary switch to "OPERATE"
7 Close housing cover
The display outputs the current 4 … 20 mA as bar graph and
digital value.
With 4 mA no segment of the bar graph appears, with 20 mA
all segments appear. This assignment is fix.
You can scale the digital value to any value between -9999 …
+9999 via the adjustment module.

It is recommended to document or save the parameter
adjustment data. They are hence available for multiple use or
service purposes.
The VEGA DTM Collection and PACTware in the licensed,
professional version provide suitable tools for systematic
project documentation and storage.
7.4 Parameter adjustment with AMS™ and PDM
For VEGA sensors, instrument descriptions for the adjustment
programs AMS™ and PDM are available as DD or EDD. The
