any internal work on the instruments must be carried out only
by personnel authorised by the manufacturer.
2.2Appropriate use
VEGABAR 54 is a pressure transmitter for measurement of
gauge pressure,absolute pressure and vacuum.
2.3Warning about misuse
Inappropriate or incorrect use of the instrument can give rise to
application-specific hazards,e.g.vessel overfill or damage to
system components through incorrect mounting or adjustment.
2.4General safety instructions
VEGABAR 54 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-specific installation standards
(e.g.the VDE regulations in Germany)as well as all prevailing
safety regulations and accident prevention rules.
2.5CE conformity
VEGABAR 54 is in CE conformity with EMC (89/336/EWG),

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 PLICSCOM or processed via the signal output.
Two-wire electronics 4…20 mA/HART for power supply and
measured value transmission on the same cable.
The power supply range can differ depending on the instru-
ment version.The exact range is stated in the "Technical data"
in the "Supplement".
3.3Adjustment
VEGABAR 54 can be adjusted with four 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
lwith manufacturer-specific adjustment programs AMS™or
PDM
laHART handheld
The entered parameters are generally saved in VEGABAR 54,
optionally also in PLICSCOM or in PACTware™.
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 EN 24180.
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.

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.
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 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 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.
Tip:
We recommend VEGA overvoltage arresters ÜS-F-LB-Iand
ÜSB 62-36G.X.
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 transmitted via the same
two-wire connection cable.The power supply range can differ
depending on the instrument version.The exact range is
stated in the "Technical data"in the "Supplement".
Provide a reliable separation between the supply circuit and
the mains circuits acc.to DIN VDE 0106 part 101.The VEGA
power supply units VEGATRENN 149AEx,VEGASTAB 690,
VEGADIS 371 as well as all VEGAMETs meet this require-
ment.
Bear in mind the following factors regarding supply voltage:
lthe reduction of the output voltage of the power supply unit
under nominal load (with a sensor current of 20.5mAor
22 mAin case of fault signal)
lthe influence of additional instruments in the circuit (see
load values in "Technical data").
VEGABAR 54 is connected with standard two-wire cable
without screen.An outer cable diameter of 5…9mm ensures
the seal effect of the cable entry.If strong electromagnetic
interference is expected,we recommend the use of screened
cable.
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.
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 outside on the housing must be connected to
the potential equalisation (low impedance).
If potential equalisation currents are expected,the connection
on the evaluation side must be made 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.
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

1Unscrew the housing cover
