VEGABAR 52 - 4 … 20 mA/HART
Product description
3.2 Principle of operation
Area of application
VEGABAR 52 is a pressure transmitter for measurement of
gauge pressure, absolute pressure or vacuum. Measured
products are gases, vapours and liquids.
Physical principle
Sensor element is the CERTEC® measuring cell with rugged
ceramic diaphragm. The process pressure causes a capacitance change in the measuring cell via the ceramic 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.
Power supply
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 instrument version. The exact range is stated in the "Technical data"
in the "Supplement".
3.3 Adjustment
VEGABAR 52 can be adjusted with four different adjustment
media:
l
l
l
l
the indicating and adjustment module PLICSCOM
with the suitable VEGA DTM in conjunction with an
adjustment software acc. to FDT/DTM standard, e.g.
PACTware™ and PC
with manufacturer-specific adjustment programs AMS™ or
PDM
a HART handheld
The entered parameters are generally saved in VEGABAR 52,
optionally also in PLICSCOM or in PACTware™.
3.4 Storage and transport

4.1 General instructions
Wetted materials
Check if the wetted materials such as seal, process fitting etc.
are suitable for the existing process conditions, such as
product, temperature etc.
Installation location
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°).
Moisture
Use the recommended cable (see chapter "Connecting to
power supply") and tighten the cable gland.
You can give your VEGABAR 52 additional protection against
moisture penetration by leading the connection cable downward 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.

Connecting to power supply
5 Connecting to power supply
5.1 Preparing the connection
Note safety instructions
Always observe the following safety instructions:
l
l
Connect only in the complete absence of line voltage
If overvoltages are expected, overvoltage arresters should
be installed.
Tip:
We recommend VEGA overvoltage arresters ÜS-F-LB-I and
ÜSB 62-36G.X.
Take note of safety
instructions for Ex
applications
In hazardous areas you should take note of the appropriate
regulations, conformity and type approval certificates of the
sensors and power supply units.
Select power supply
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 requirement.
Bear in mind the following factors regarding supply voltage:
l
l
the reduction of the output voltage of the power supply unit
under nominal load (with a sensor current of 20.5 mA or
22 mA in case of fault signal)
the influence of additional instruments in the circuit (see
load values in "Technical data").
VEGABAR 52 is connected with standard two-wire cable
without screen. An outer cable diameter of 5 … 9 mm ensures
the seal effect of the cable entry. If strong electromagnetic
interference is expected, we recommend the use of screened
cable.
Cable gland ½ NPT
On VEGABAR 52 with cable gland ½ NPT and plastic housing,
a metal ½" threaded insert is moulded in the plastic housing.
27507-EN-051004
Selecting the connection cable
VEGABAR 52 - 4 … 20 mA/HART
13
Connecting to power supply
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.
Cable screening and grounding
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. 1 nF, 1500 V). The low frequency potential equalisation
currents are thus suppressed, but the protective effect against
high frequency interference signals remains.
Select connection
cable for Ex applications
Take note of the corresponding installation regulations for Ex
applications. In particular, make sure that no potential equalisation 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.
5.2 Connection procedure
Proceed as follows:
Unscrew the housing cover
2
If an indicating and adjustment module is installed, remove
it by turning it slightly to the left.
3
Loosen compression nut of the cable entry
4
Remove approx. 10 cm (4 in) of the cable mantle, strip
approx. 1 cm (0.4 in) insulation from the ends of 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)

VEGABAR 52 can be used for process pressure as well as for
level measurement. Default setting is process pressure
measurement. The mode can be changed in the adjustment
menu.
Depending on your application, only the respective subchapter
"Process pressure measurement" or "Level measurement" will
apply. There you will find the individual adjustment steps.
Optional settings
Parameter adjustment "Process pressure measurement"
Additional adjustment and diagnosis options such as e.g.
scaling, simulation or trend curve presentation are shown in
the following menu schematic. You will find a detailed
description of these menu items in the operating instructions
manual of the indicating and adjustment module PLICSCOM.
Process pressure measurement
Set up VEGABAR 52 in the following sequence:
1

8.3 Exchanging the electronics
The electronics of VEGABAR 52 consists of the measuring cell
electronics and the processing electronics. The measuring cell
electronics in the process fitting is not accessible to the user.
The processing electronics is in the form of a module in the
housing. If this electronics is defective, it can be exchanged by
the user.
The electronics modules differ only in their signal output and
are suitable for all VEGABAR series 50 and 60 sensors. The
following types are available:
l
l
l
BR-E.60H (4 … 20 mA/HART)
BR-E.60P (Profibus PA)
BR-E.60F (Foundation Fieldbus)
An exchange of the same type is thus possible. If there is no
electronics module available on site, it can be ordered from the
responsible VEGA agency. It can be ordered with or without
serial number.
The electronics with serial number includes order-specific
data such as factory setting, seal material etc. The electronics
without serial number includes no order-specific data. The
serial number can be found on the type label of VEGABAR 52
or on the delivery note.
In both cases, the function of VEGABAR 52 is ensured.

10.2 Planning
Safety function
The measuring system generates on the current output a
signal between 3.8 mA and 20.5 mA proportional to the
process pressure or level.
This analogue signal is transmitted to a connected processing
unit for monitoring the following conditions:
l
Exceeding or falling below a set pressure value
The safety function is that a signal is outputted if the set
switching point is reached on the processing unit.
Safe condition
The safe condition depends on the mode and is stated in the
following chart:
Safe condition
Output current in safe
condition
Monitoring upper
pressure value
Monitoring lower

Exceeding of the
switching point
Falling below the
switching point
> switching point (+1 %) < switching point (+1 %)
Failure current "fail low"
<3.6 mA
<3.6 mA
Failure current "fail high"
>21.5 mA
>21.5 mA
The current tolerance ±1 % refers to the full measuring range
of 16 mA.
Fault description
A fail-safe failure (safe failure) exists if the measuring system
changes to the defined safe condition or to the failure mode
without demand of the process.
If the internal diagnosis system detects an failure, the
measuring system goes to failure mode.
A dangerous undetected failure exists if the measuring system
does neither go to the defined safe condition when required by
the process nor to the failure mode.
Configuration of the processing unit
If the measuring system delivers output currents of "fail low" or
"fail high", this can be due to a failure.
46
VEGABAR 52 - 4 … 20 mA/HART
27507-EN-051004
The processing unit must therefore interpret such currents as
failure and output a suitable fault signal.
Functional safety acc. to IEC 61508-4 (SIL)
If this is not the case, the appropriate shares of the failure rates
must be assigned to the dangerous failures. Therefore the
stated values in chapter "Safety-relevant characteristics" can
deteriorate.
Low demand mode
If the demand rate is only once a year, then the measuring
system can be used as safety-relevant subsystem in "low
demand mode" (IEC 61508-4, 3.5.12).
If the ratio of the internal diagnostics test rate of the measuring
system to the demand rate exceeds the value 100, the
measuring system can be treated in the way it is executing a
safety function in the mode with low demand rate (IEC 61508-2,
7.4.3.2.5).
Corresponding characteristics is the value PFDavg (average
Probability of dangerous Failure on Demand). It is dependent
on the test interval TProof between the function tests of the
protective function.
Numbers see paragraph "Safety-technical characteristics".
High demand mode
If the "low demand mode" does not apply, the measuring
system must be used as safety-relevant subsystem in "high
demand" (IEC 61508-4, 3.5.12).
The fault tolerance time of the complete system must be higher
than the sum of the reaction times or the diagnostics test
periods of all components in the safety chain.
Corresponding characteristics is the value PFH (failure rate).
Numbers see paragraph "Safety-technical characteristics".

VEGABAR 52 - 4 … 20 mA/HART
Failure rates are constant, wear of the mechanical parts is
not taken into account
Failure rates of external power supplies are not included
Multiple errors are not taken into account
The average ambient temperature during the operating
time is +40°C (104°F)
The environmental conditions correspond to an average
industrial environment
The lifetime of the components is around 8 to 12 years
(IEC 61508-2, 7.4.7.4, remark 3)

General instructions and restrictions
The repair time (exchange of the meas. system) after a failsafe error is eight hours (MTTR = 8 h)
The scanning interval of a connected control and processing unit is max. 1 hour to react on dangerous,
detectable errors
The communication via the HART interface is not used for
transmission of safety-relevant information
The measuring system should be applied acc. to the
application by taking pressure, temperature, density and
chemical properties of the medium into account.
The application-specific limits must be maintained and the
specifications must not be exceeded.
10.3 Adjustment instructions and parameter
adjustment
Instrument parameters
Since the plant conditions influence the safety of the
measuring system, the instrument parameters must be set
according to the application.
VEGABAR 52 suitable for the VEGA-DTM in conjunction with
an adjustment software acc. to FDT/DTM standard, e.g.
PACTware™ is permitted as auxiliary means.
Create a measurement loop
Via the adjustment software, the parameter "Sensor acc. to
SIL" must be selected in the menu item "Measurement loop".
Reaction in case of failure
The parameter adjustment of the interference current influences the safety-technical characteristics. For safety-relevant
applications only the following inference currents are allowed:
l
l
fail low = <3.6 mA
fail high = 22 mA
Note:
The setting "Hold value" must not be selected.
The damping of the output signal must be adapted to the
process safety time.
Inadmissible modes
The measured value transmission by means of HART signal
as well as HART multidrop mode are not permitted.
Inspection possibilities
The effectivity of the set parameters must be checked in a
suitable way.

Access locking
After connecting the instrument, the output signal jumps to
the set interference current (at the end of the switch on
phase)
In mode "Simulation", the signal current can be simulated
independent of the current pressure or level
To avoid unwanted or unauthorized modification, the set
parameters must be protected against unintentional access:
l
l
Activate the password protection on the adjustment
program PACTware™
Activate the PIN on the adjustment module PLICSCOM
The access by means of HART handheld or similar is not
permitted.
The protection against unintentional or unauthorized adjustment can be prevent by e.g. sealing the housing cover.
Caution:
After a reset of the values, all parameters must be checked or
readjusted.
10.4 Set up
Take note of the mounting and installation instructions of the
operating instructions manual.
Within the setup, we recommend checking the safety function
by means of an initial filling.
10.5 Reaction during operation and in case of
failure
The adjustment elements must not be modified during
operation.
In case of modifications during operation, you have to take
note of the safety functions.
Occurring fault signals are described in the appropriate
operating instructions manual.
27507-EN-051004
In case of detected failures or fault signals, the entire
measuring system must be switched out of service and the
process held in a safe condition by means of other measures.
An electronics exchange is easily possible and described in
the operating instructions manual.
VEGABAR 52 - 4 … 20 mA/HART
49
Functional safety acc. to IEC 61508-4 (SIL)
If due to the detected failure, the electronics or the complete
sensor is interchanged, the manufacturer must be informed
(incl. a fault description).
10.6 Recurring function test
The recurring function test serves to reveal potential dangerous errors that are otherwise not discernible. The function of
the measuring system must be checked at adequate intervals.
The operator is responsible for choosing the type of test and
the intervals in the stated time frame. The time frame depends
on the PFDavg value acc. to the chart and diagram in section
"Safety-related characteristics".
In high demand rate, no recurring function test is arranged in
IEC 61508. A proof of the functional efficiency is seen in the
more frequent demand of the measuring system. In double
channel architectures it is useful to proof the redundancy by
recurring function tests in appropriate intervals.
The test must be carried out in a way that verifies the flawless
operation of the safety functions in conjunction with all system
components.
This is ensured by a controlled reaching of the response height
during filling. If filling up to the response height is not possible,
then a response of the measuring system must be triggered by
a suitable simulation of the level or the physical effect.
The methods and procedures used during the tests must be
stated and their suitability must be specified. The tests must be
documented.
If the function test proves negative, the entire measuring
system must be switched out of service and the process held
in a safe condition by means of other measures.
In the double channel architecture 1oo2D this applies
separately to both channels.
