3.2Principle of operation
VEGABAR 53 is a pressure transmitter for measurement of
gauge pressure,absolute pressure or vacuum.Measured
products are gases,vapours and liquids up to 600 bar.With
flush version also viscous liquids.
The process pressure acts via the stainless steel diaphragm to
the sensor element1).Aresistance change is caused which is
converted into a respective output signal and outputted as
measured value.
Power supply is via the Profibus DP/PA segment coupler or
VEGALOG 571 EP cards.Atwo-wire cable acc.to Profibus
specification serves as carrier of both power and digital data
signals for multiple sensors.The instrument profile of
VEGABAR 53 corresponds to profile specification version 3.0.
The GSD (instrument master files)and bitmap files necessary
for planning your Profibus-DP-(PA)communication network
are available from the download section on the VEGA
homepage www.vega.com under "Services –Downloads –
Software –Profibus".There you can also find the appropriate
certificates.InaPDM environment,an EDD (Electronic Device
Description)is also required to enable the full range of sensor
functions (also available as a download).ACDwith the
appropriate files can be ordered via e-mail under info@de.
vega.com or by phone from one of the VEGA agencies under
the order number "DRIVER.S".
3.3Adjustment
VEGABAR 53 can be adjusted with three different adjustment
media:
lthe indicating and adjustment module PLICSCOM
lwith the suitable VEGA DTM in conjunction with an
adjustment software acc.to FDT/DTM standard,e.g.
PACTware™and PC
lthe Simatic adjustment program PDM
The entered parameters are generally saved in VEGABAR 53,
optionally also in PLICSCOM or in PACTware™.
1)For meas.ranges up to 16 bar:piezoresistive sensor element with internal
transmission liquid,for meas.ranges from 25 bar:strain gauge (DMS)
sensor element on the rear of the stainless steel diaphragm (dry).

3.4Storage and transport
Your instrument was protected by packaging during transport.
Its capacity to handle normal loads during transport is assured
by a test acc.to DIN 55439.
The packaging of standard instruments consists of environ-
ment-friendly,recyclable cardboard.For special versions,PE
foam or PE foil is also used.Dispose of the packaging material
via specialised recycling companies.
Instruments for oxygen applications are welded in PE foil and
provided with a label "Oxygen!Use no Oil".Remove this foil
just before mounting the instrument!

4Mounting
4.1General instructions
Check if the wetted materials such as seal,process fitting etc.
are suitable for the existing process conditions,such as
product,temperature etc.
Caution:
After removing the diaphragm protection,the diaphragm must
not be impressed.
Select an installation position you can easily reach for
mounting and connecting as well as later retrofitting of an
indicating and adjustment module.The housing can be rotated
by 330°without the use of any tools.You can also install the
indicating and adjustment module in four different positions
(each displaced by 90°).
Use the recommended cable (see chapter "Connecting to
power supply")and tighten the cable gland.
You can give your VEGABAR 53 additional protection against
moisture penetration by leading the connection cable down-
ward in front of the cable entry.Rain and condensation water
can thus drain off.This applies mainly to mounting outdoors,in
areas where moisture is expected (e.g.by cleaning processes)
or on cooled or heated vessels.

Danger:
Instruments for oxygen applications should be unpacked just
before mounting.After removing the protective cover of the
process fitting,the label "O₂"will be visible on the process
fitting.Penetration of oil,grease and dirt should be avoided.
Danger of explosion!
4.2Mounting information
VEGABAR 53 functions in any installation position2).Itis
mounted acc.to the same regulations like a manometer
(DIN EN 839-2).
Information:
We recommend using lock fittings,measuring instrument
holders and siphons from the line of VEGA accessories.
4.3Mounting procedure
To mount VEGABAR 53,a welded socket is necessary.Use
components from the line of VEGA mounting accessories:
lWelded socket G1Bfront flush,max.150°C(302°F), article
no.2.27868
lWelded socket G1Bfront flush O-ring,article no.2.27867
lWelded socket G½B,article no.27866

5Connecting to power supply
5.1Preparing the connection
Always observe the following safety instructions:
lConnect only in the complete absence of line voltage
lIf overvoltages are expected,overvoltage arresters should
be installed acc.to Profibus specification.
In hazardous areas you should take note of the appropriate
regulations,conformity and type approval certificates of the
sensors and power supply units.
Power is supplied via a Profibus DP/PA segment coupler or a
VEGALOG 571 EP input card.The power supply range can
differ depending on the instrument version.The exact range is
stated in the "Technical data"in the "Supplement".
VEGABAR 53 is connected with screened cable acc.to the
Profibus specification.Power supply and digital bus signal are
carried over the same two-wire connection cable.
An outer cable diameter of 5…9mm ensures the seal effect
of the cable entry.
Please make sure that your installation is carried out acc.to
the Profibus specification.In particular,make sure that the
termination of the bus is done with appropriate terminating
resistors.
When using VEGABAR 53 with cable entry 1/2"NPT and
plastic housing,a metal 1/2"threaded insert is moulded into
the plastic housing.
Caution:
No grease should be used when screwing the NPT cable
gland or steel tube into the threaded insert.Standard grease
can contain additives affecting the connection between
threaded insert and housing.This will influence the stability of
the connection and the tightness of the housing.
In systems with potential equalisation,connect the cable
screen directly to ground potential at the power supply unit,in
the connection box and at the sensor.The screen in the sensor

must be connected directly to the internal ground terminal.The
ground terminal outside on the housing must be connected to
the potential equalisation (low impedance).
In systems without potential equalisation,connect the cable
screen directly to ground potential at the power supply unit and
at the sensor.In the connection box or T-distributor,the screen
of the short stub to the sensor must not be connected to
ground potential or to another cable screen.The cable screens
to the power supply unit and to the next distributor must be
connected to each other and also connected to ground
potential via a ceramic capacitor (e.g.1nF,1500 V). The low
frequency potential equalisation currents are thus suppressed,
but the protective effect against high frequency interference
signals remains.
The total capacitance of the cable and of all capacitors must
not exceed 10 nFin Ex applications.
Take note of the corresponding installation regulations for Ex
applications.In particular,make sure that no potential equal-
isation currents flow over the cable screen.In case of
grounding on both sides this can be achieved by the use of a
capacitor or a separate potential equalisation.
5.2Connection procedure
Proceed as follows:
1Unscrew the housing cover
2If an indicating and adjustment module is installed,remove
it by turning it slightly to the left.
3Loosen compression nut of the cable entry
4Remove approx.10 cm (4in)of the cable mantle,strip
approx.1cm (0.4in)insulation from the ends of the
individual wires
5Insert the cable into the sensor through the cable entry
6Lift the opening levers of the terminals with a screwdriver
(see following illustration)
7Insert the wire ends into the open terminals according to
the wiring plan
