This operating instructions manual applies to the following instrument
versions:
• Software from 3.82
3.2 Principle of operation
VEGABAR 52 is a pressure transmitter for use in the paper, food
processing and pharmaceutical industries as well as in water/sewage
water plants. Depending on the version, it is used for level, gauge,
absolute pressure or vacuum measurement. Measured products are
gases, vapours and liquids, also those containing abrasive sub-
stances.
Sensor element is the CERTEC®measuring cell with robust, depend-
entontheprocessttingalsofront-ush,abrasion-resistantceramic
diaphragm.The process pressure causes a capacitance change in
the measuring cell via the ceramic diaphragm.This change is con-
verted into an appropriate output signal and outputted as measured
value.

The CERTEC®measuring cell is also equipped with a temperature
sensor. The temperature value can be displayed via the display and
adjustment module as well as processed via the signal output (with
digital versions).
As a standard feature, the CERTEC®measuring cell is equipped with
a lateral, recessed seal.
Instruments with double seal have an additional front seal.

3.3 Operation
The instrument can be adjusted with the following adjustment media:
• With the display and adjustment module
• with the suitable VEGA DTM in conjunction with an adjustment
software according to the FDT/DTM standard, e.g. PACTware and
PC
3.4 Packaging, transport and storage
Your instrument was protected by packaging during transport. Its
capacity to handle normal loads during transport is assured by a test
based on ISO 4180.
The packaging of standard instruments consists of environment-
friendly, recyclable cardboard. For special versions, PE foam or PE
foil is also used. Dispose of the packaging material via specialised
recycling companies.
Transport must be carried out under consideration of the notes on the
transport packaging. Nonobservance of these instructions can cause
damage to the device.
The delivery must be checked for completeness and possible transit
damage immediately at receipt. Ascertained transit damage or con-
cealed defects must be appropriately dealt with.

5.1 Preparing the connection
Always keep in mind the following safety instructions:
• Connect only in the complete absence of line voltage
• If overvoltage surges are expected, overvoltage arresters should
be installed
Tip:
We recommend using VEGA overvoltage arresters B63-48 and
ÜSB 62-36G.X.
Inhazardousareasyoumusttakenoteoftherespectiveregulations,
conformityandtypeapprovalcerticatesofthesensorsandpower

Power supply and current signal are carried on the same two-wire
cable.Thevoltagesupplyrangecandierdependingontheinstru-
ment version.
Thedataforpowersupplyarespeciedinchapter"Technical data".
Provide a reliable separation between the supply circuit and the
mains circuits according to DIN EN 61140 VDE 0140-1.The VEGA
power supply units VEGATRENN 149A Ex, VEGASTAB 690 as well
as all VEGAMETs and VEGASCANs meet this requirement.
Keepinmindthefollowingadditionalfactorsthatinuencetheoperat-
ing voltage:
• Output voltage of the power supply unit can be lower under nomi-
nal load (with a sensor current of 20.5 mA or 22 mA in case of fault
message)
• Inuenceofadditionalinstrumentsinthecircuit(seeloadvaluesin
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.
Usecablewithroundcross-section.Acableouterdiameterof
5…9mm(0.2…0.35in)ensuresthesealeectofthecablegland.
Ifyouareusingcablewithadierentdiameterorcross-section,
exchange the seal or use a suitable cable gland.
We generally recommend the use of screened cable for HART multi-
drop mode.

housing.Thiswouldinuencethestabilityoftheconnectionandthe
tightness of the housing.
If screened cable is necessary, connect the cable screen on both
ends to ground potential. In the sensor, the screen must be connected
directly to the internal ground terminal.The ground terminal on the
outside of the housing must be connected to the potential equalisa-
tion (low impedance).
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,buttheprotectiveeectagainsthighfrequencyinterfer-
ence signals remains.
Warning:
Considerablepotentialdierencesexistinsidegalvanicplantsaswell
as vessels with cathodic corrosion protection.Very large equalisa-
tioncurrentscanowthroughthecablescreenwhenthescreen
is grounded on both ends. To avoid this, the cable screen must be
connected to ground potential only on one end (inside the switch-
ing cabinet) in such applications.The cable screen must not be
connected to the internal ground terminal in the sensor and the outer
ground terminal on the housing not to potential equalisation!
Information:
Themetallicpartsoftheinstrument(transmitter,processtting,etc.)
are conductively connected with the inner and outer ground terminal
on the housing.This connection exists either as a direct metallic
contact or via the shielding of the special connection cable on instru-
mentswithexternalelectronics.Youcanndspecicationsonthepo-
tentialconnectionswithintheinstrumentinchapter"Technical data".
Take note of the corresponding installation regulations for Ex applica-
tions. In particular, make sure that no potential equalisation currents
owoverthecablescreen.Incaseofgroundingonbothsidesthis
can be achieved by the use of a capacitor or a separate potential
equalisation.
5.2 Connection procedure
Proceed as follows:
1. Unscrewthehousingcover
2. If a display and adjustment module is installed, remove it by turn-
ing it to the left.
3. Loosen compression nut of the cable entry
4. Remove approx. 10 cm of the cable mantle, strip approx. 1 cm
insulation from the individual wires
5. Insert the cable into the sensor through the cable entry
6. Lift the opening levers of the terminals with a screwdriver (see
following illustration)
