ibed in this operating instructions manual

2.2 Appropriate use

VEGAWELL 72 is a suspension pressure transmitter for level and gauge measurement.
You can nd detailed information on the application range in chapter "Product description".
Operational reliability is ensured only if the instrument is properly used according to the specications in the operating instructions manual as well as possible supplementary instructions.
For safety and warranty reasons, any invasive work on the device beyond that described in the operating instructions manual may be carried out only by personnel authorised by the manufacturer. Arbitrary conversions or modications are explicitly forbidden.

2.3 Warning about misuse

Inappropriate or incorrect use of the instrument can give rise to application-specic hazards, e.g. vessel overll or damage to system components through incorrect mounting or adjustment.

2.4 General safety instructions

This is a high-tech instrument requiring the strict observance of standard regulations and guidelines. The user must take note of the safety instructions in this operating instructions manual, the country-specic installation standards as well as all prevailing safety regulations and accident prevention rules.
The instrument must only be operated in a technically awless and reliable condition. The operator is responsible for trouble­free operation of the instrument.

2 For your safety
During the entire duration of use, the user
must make sure that the occupational safety measures taken always comply with current valid policy as well as new regulations.

2.5 Safety approval markings and safety tips

The safety approval markings and safety tips on the device must be observed.

2.6 CE conformity

VEGAWELL 72 is in CE conformity with EMC (89/336/EWG) and LVD (73/23/EWG).
Conformity has been judged according to the following standards:
l EMC:
- Emission EN 61326: 1997/A1: 1998 (class B)
- Susceptibility EN 61326: 1997/A1:1998
l LVD: EN 61010-1: 1993
2.7 Fulfilling
of NAM
With respect to interference resistance and emitted interfer­ence, the NAMUR recommendation NE 21 is fullled.
With respect to compatibility, the NAMUR recommendation NE 53 is fullled. This applies also to the corresponding
indicating and adjustment components. VEGA instruments are generally upward and downward compatible.
l Sensor software for DTM VEGAWELL 72 HART l DTM
VEGAWELL 72 for adjustment software PACTware
The parameter adjustment of the basic sensor functions is
independent of the software version. The range of available functions depends on the respective software version of the individual components.
The software version of the instrument can be read out via PACTware.

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 dier depending on the instrument version.
Data for power supply are specied in chapter "Technical data".

3.3 Operation

VEGAWELL 72 - 4 20 mA/HART can be adjusted with dierent 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 PACTwareand PC optionally also in the PC.

points when selecting the installation
location.
l Sidewa
ys movements of the transmitter can cause
measurement errors
à Therefore, mount VEGAWELL 72 in
a calm area or in a
suitable protective tube
Information:
We recommend
the measuring instrument holder from the VEGA line of accessories (article no. BARMONT.B) for fastening VEGAWELL 72.
l The protective cover prevents mechanical damage to the
measuring cell. It
should only be removed when the sensor
is deployed in extremely polluted water.
Note the following item for pressure compensation:
l The
connection cable has a capillary for atmospheric
pressure compensation
à Therefore lead
the cable end into a dry space or directly
into a suitable connection housing.
