3.2Principle of operation
VEGABAR 54 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 meas-
urement.Measured products are gases,vapours and liquids,
also those containing abrasive substances.
The sensor element is the small CERTEC
®
measuring cell with
flush,abrasion resistant ceramic diaphragm.The hydrostatic
pressure of the medium or the process pressure causes a
capacitance change in the measuring cell via the diaphragm.
This change is converted 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 indicating and adjustment module or processed via the
signal output.
Power is supplied via the H1Fieldbus.Atwo-wire cable
according to Fieldbus specification serves as carrier of both
power and digital data signals for multiple sensors.This cable
can be operated in two versions:
lvia an H1interface card in the control system and
additional power supply
lvia a linking device with HSE (High speed Ethernet)and
additional voltage supply according to IEC 61158-2
The DD (Device Descriptions)and CFF (capability files)
necessary for planning and configuration of your FF (Founda-
tion Fieldbus)communication network are available in the
download area of the VEGA homepage www.vega.com under
"Services -Downloads -Software -Foundation Fieldbus".The
appropriate certificates are also available there.ACDwith the
appropriate files and certificates can be ordered via e-mail
under [e-mail] or by phone from one of the VEGA
agencies under the order number "DRIVER.S".

4.1General instructions
Make sure that the wetted parts of VEGABAR 54,especially
the seal and process fitting,are suitable for the existing
process conditions such as pressure,temperature etc.as well
as the chemical properties of the medium.
You will find specification in chapter "Technical data"in the
"Supplement".
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 cables (see chapter "Connecting to
power supply")and tighten the cable gland.
You can give your VEGABAR 54 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.

5Connecting to voltage supply
5.1Preparing the connection
Generally note the following safety instructions:
lConnect only in the complete absence of line voltage
lIf overvoltage surges are expected,overvoltage arresters
should be installed according to Foundation Fieldbus
specification
In hazardous areas you should take note of the appropriate
regulations,conformity and type approval certificates of the
sensors and power supply units.
VEGABAR 54 requires a supply voltage of 9…32 VDC.
Power and the digital bus signal are carried on the same two-
wire connection cable.Power is supplied via the H1power
supply.
VEGABAR 54 is connected with screened cable according to
Fieldbus specification.Acable diameter of 5…9mm ensures
the seal effect of the cable gland.
Make sure that the entire installation is carried out according to
the Fieldbus specification.In particular,make sure that the
termination of the bus is done with appropriate terminating
resistors.
OnVEGABAR 54 with cable gland ½NPT and plastic housing,
a metal ½" threaded insert is moulded in 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).

Connecting to voltage supply
29728-EN-061219

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
