1.1 Function

Continuous level measurement with ultrasonic
sensors is based on the running time meas­urement of ultrasonic pulses.

Product description

VEGASON 54 … 56 sensors are a newly
developed generation of extremely compact
ultrasonic sensor for level measurement.
They were developed for liquids and
especially for solids and larger measuring
distances. They are the right choice for
applications in silos, bunkers and material
dumps.

Due to small housing dimensions and proc­ess fittings, the compact sensors are an
unobtrusive, and most of all, very cost­effective solution for your level measurement
applications. With the integrated display and
a special sensor intelligence in conjunction
with large measuring ranges, they enable
high-precision level measurement and can
be used for applications in which the advan­tages of non-contact measurement could
never before be realised.

The outputs generate a digital Profibus PA
signal as output, i.e. measurement signal.

Measuring principle

High-performance piezoceramic transducers
emit focused ultrasonic pulses which are
reflected by the product surface. The meas­urement electronics prepares a precise im­age of the environment from the reflected
ultrasonic pulses. The transducers work both
as transmitter and receiver. As receiver, the
transducers are high-sensitivity piezo micro­phones.

Meas.
distance

emission - reflection - reception

The measurement electronics precisely cal­culates the distance between transducer and
medium from the speed of sound and the
measured running time of the emitted sound
impulse. The distance is then converted into
a level-proportional signal and, in conjunction
with the sensor parameter settings, made
available as a precise, calibrated level value.

Since the speed of sound is subject to tem­perature influence, the transducer also con­tinuously detects the ambient tempera­ture, so that the level is precisely measured
even in case of varying ambient temperature.

4 VEGASON 54P … 56P

Product description

Output signal

The level-proportional Profibus PA measure­ment signal is processed and outputted
completely digitally. Digital processing of the
measurement signal ensures an accuracy
which could be never reached by an ana­logue measurement signal, as the digital
signal is always transmitted error-free right
up to the last decimal position. Varying
resistances or tiny leakage currents do not
influence the accuracy of digital technology.
The digital signal is always clear and unam­biguous.

The digital signal, giving a faithful representa­tion of the adjusted measuring range of the
sensor, can be modified by various param­eter settings.

Measured value display

As an option, the series 50 ultrasonic sensors
can be equipped with an indicating instru­ment for direct, local level survey. The indi­cating instrument shows the precise level by
means of the analogue bar graph and the
digital number value. In addition to the indica­tion in the sensor, you can have the level
displayed with the VEGADIS 50 external
indicating instrument at a distance of up to 25
m from the sensor. The external measured
value display operates, like the integrated
display, independently of the PA output signal
and can be modified through individual pa­rameter settings.

1.3 Profibus output signal

PROPRO

PROcess

PROPRO
sult of a joint project of thirteen companies
and five universities. The companies Bosch,
Klöckner-Möller and Siemens played a deci­sive role. The specifications of the bus are
described in the protocol layers 1, 2 and 7 of
the ISO/OSI reference model and are avail­able from the PNO (Profibus user organisa­tion). Layers 3 … 5 have not yet been
developed as a standard, leaving Profibus
with far-reaching perspectives for the future.

Today approx. 600 companies make use of
Profibus technology and belong to the PNO.
Profibus
Specification, Profibus
Periphery and Profibus
mation.

As a process automation bus, Profibus PA
enables power supply over the bus. Up to 32
sensors can be operated on a shielded two­wire cable that carries both power supply
and measurement signal. In Ex areas, up to
ten sensors can be connected from the PA
level to one two-wire cable (EEx ia).

Bus structure

The Profibus DP and PA network consists of
up to 126 master and slave participants.
Data are always exchanged from point to
point, with the data traffic being exclusively
controlled and checked by master devices.
Communication is carried out according to
the Token-Passing procedure. This means
that the master holding the Token can contact
the slaves, give instructions, enquire data
and cause the slaves to receive and transmit
data. After the work is done or after a prede­termined time interval, the Token is passed
on by the master to the next master.

One or several Master-Class 2 can operate in
a Profibus network. As a rule, Master-Class 2
devices are engineering, adjustment or visu­alisation stations. The VEGA adjustment soft­ware VVO (VEGA Visual Operating) operates
as Master-Class 2 participant on the DP bus
and can work on an engineering PC, on an
adjustment PC or on the process control
computer and can access any VEGA sensor
on the PA level.

Instrument master file

A so-called GSD file is delivered with every
VEGASON Profibus sensor. This file is nec­essary for integrating the sensor into the bus
system. The GSD file (instrument master file)
contains, beside the sensor name and the
manufacturer, the sensor-specific communi­cation parameters which are necessary for a
stable integration of the sensor in the bus.

Load the GSD file belonging to the sensor
into your bus configuration program. If the
GSD file is not available, it can be loaded
from the VEGA homepage:
http://www.vega.com.

Do not confuse the GSD file with the EDD
(Electronic Device Description), a file neces­sary for the PDM environment (this can be
also found on the VEGA homepage).

Product description

1.4 Adjustment

Each measuring situation is unique. For that
reason, every ultrasonic sensor needs some
basic information on the application and the
environment, e.g. which level means "empty"
and which level "full". Beside this "empty and
full adjustment", many other settings and
adjustments are possible with VEGASON
ultrasonic sensors. The output of echo
curves or the calculation of vessel lineari­sation curves by means of vessel dimen­sions are only two examples.

Profibus adjustment scheme

In the Profibus environment, there are differ­ent adjustment concepts and adjustment
tools which often differ considerably from
manufacturer to manufacturer. From the us­er’s point of view, a manufacturer-independ­ent adjustment program which could be
operated directly on the Profibus DP, as well
as at any system node (e.g. the engineering
station or the process control), would be
ideal.

In the past, only the program "SIMATIC PDM",
based on the HART® adjustment scheme,
could fulfil this wish (though with the limita­tions common to HART®). As with HART®, the
availability of an instrument-specific database
for a comprehensive adjustment with PDM
(Process Device Managing) is a requirement.
Otherwise, only the basic instrument func­tions, such as adjustment, are available. In
the PDM environment, this instrument-spe­cific database is called EDD (Electronic De­vice Description), in perfect analogy to the
HART® environment which also requires,
except for the VEGA HART® instruments, a
DD (Device Description) for each sensor.

We are aware of the disadvantages of the
HART® environment: for each sensor/partici­pant, an individual DD must be loaded, which
in addition, must always be the latest and
most up-to-date DD. Special adjustment
options such as e.g., the output of an echo
curve, are available neither with HART® nor
with PDM. User-friendly adjustment is out of
the question. With VEGA’s adjustment pro­gram VVO, those restrictions belong to the
past.

The legitimate wish of many Profibus users
for a manufacturer-independent adjustment
tool without EDD has been realised in the
form of PACTware

TM 1)

. An association of a
number of process technology companies
developed PACTwareTM: a Process Automa­tion Configuration Tool that can run different
manufacturer software tools under a stand­ardised user interface and adjustment
scheme. Specialists call this technology Field
Device Transcription. Just as different Win­dows printer drivers enable operation of
completely different printers under a single
user interface, PACTware

TM

enables operation
of all field instruments under a single user
interface. Instrument-specific databases
(EDD), like those required for SIMATIC PDM,
are not necessary.

As a result of this development, four adjust­ment media are available for VEGA Profibus
sensors:

- adjustment with the PC and the adjustment

program VVO (VEGA Visual Operating) as
stand-alone tool, on the segment coupler
or directly on the sensor.

- adjustment with the detachable adjustment

module MINICOM in the sensor

- adjustment with the SIMATIC PDM adjust-

ment program (requires EDD instrument
databases) from the control room

- adjustment with the manufacturer-inde-

pendent user interface PACTwareTM on the
sensor, from the control room or on the
segment coupler.

VEGASON 54P … 56P 7

Product description

Adjustment with the adjustment pro­gram VVO - VEGA Visual Operating

The setup and adjustment of the ultrasonic
sensors is generally done on the PC with the
adjustment program VEGA Visual Operating
(VVO) under Windows®. The program leads
quickly through adjustment and parameter
setting by means of pictures, graphics and
process visualisations.

Note:

The adjustment program VVO must be avail­able in version 2.70 or higher.

The VEGA adjustment software VVO (VEGA
Visual Operating) operates either as a
subprogram of the host program PACTware
acc. to the FDT concept (Field Device Tool) or
as an independent adjustment program on
any PC, engineering station or process con­trol computer.

The adjustment program recognises the sensor type

Visualised input of a vessel linearisation curve in the
adjustment program VVO

VEGA’s adjustment program VVO can ac­cess the adjustment options of VEGA sen­sors in their entirety and, if necessary, can
update the complete sensor software. For
communication with Profibus sensors, the
adjustment program either requires a
Profibus-Master-Class2 interface card or the
interface adapter VEGACONNECT 3.
The PC with the Profibus interface card can
be connected directly to any point on the DP
bus with the standard RS 485 Profibus cable.
In conjunction with the adapter
VEGACONNECT, the PC can be connected
directly to the sensor. VEGACONNECT com­municates via a small plug directly with the
respective sensor.
The adjustment and parameter data can be

TM

saved at any time on the PC with the adjust­ment software and can be protected by
passwords. If necessary, the adjustments
can be transferred quickly to other sensors.
In practice, the adjustment program VVO is
often installed as a tool on an engineering
station or an operating station. VVO then
accesses all VEGA sensors directly over the
bus via the Profibus interface card (e.g. from
Softing) as Master Class 2, from the DP level
to the PA level (via segment coupler) right
down to the individual sensor.
Beside the instrument master file (GSD), with
which a sensor is logged into the Profibus
system, the majority of all Profibus sensors
requires for adjustment, beside the specific
adjustment software, also a so-called EDD
(Electronic Device Description) for each
sensor, in order to access and adjust the
sensor from the bus levels. This is not the
case with VVO. The adjustment software
VVO can communicate at any time with all
VEGA sensors without the help of a special
database. Of course, all other non-Profibus
VEGA sensors can be adjusted with the
adjustment software as well (4 … 20 mA
sensors or VBUS sensors). With VEGA sen­sors, it is not necessary to go looking for the
latest EDD. This is the essential requirement
for a manufacturer-independent adjustment
program, like PACTwareTM, anticipated by
many users, see following pages.

Adjustment with the SIMA TIC PDM
adjustment program

To adjust all essential functions of the VEGA
sensor with the adjustment station SIMATIC
PDM from Siemens, a so-called EDD is re­quired. Without this EDD, only the basic func­tions such as min./max. wet adjustment or
integration time can be adjusted with the
PDM adjustment program. Further important
adjustment functions, such as input of the
measuring environment or false echo stor­age, are not available without EDD. After
integration of the EDD files in the Simatic PDM
adjustment software, all important adjustment
functions are accessible. If it is not at hand,
the obligatory GSD (instrument master file)
as well as the EDD (Electronic Device De­scription) necessary for PDM can be
downloaded from the VEGA homepage
(http://www.vega.com).

Adjustment with PACTware

PACTwareTM is a manufacturer-independent
automation/configuration tool through which
access to instruments of different manufac­turers (Krohne, Pepperl + Fuchs, VEGA,
WIKA-, Bürkert…) is possible. The VEGA
adjustment software VVO works as a
subprogram/menu. PACTwareTM activates the
required menu options for the sensor/instru­ment being accessed.

PACTwareTM looks different than VVO and is
designed with a tree structure. Operating

1.5 T ype survey

VEGASON 54 … 56 sensors are a newly
developed generation of very compact ultra­sonic sensors for large measuring ranges.
For shorter measuring ranges, VEGASON
51 … 53 sensors are used.

Thanks to the small housing dimensions and
process fittings, the compact sensors are a
very cost-effective solution for your level
measurement applications. Swivelling holders
enable quick orientation of the transducers to
the liquid or solid surface. Because the sen­sor electronics and transducer can be sepa­rated, installation is very simple. It is possible
to separate the sensor electronics up to
300 m from the transducer. As a result, the
transducer can handle ambient temperatures
up to 150°C (VEGASON 56).

General features

• Application in solids and liquids.

• Measuring range 0.8 m … 70 m.

• Ex-approved in Zone 10 (IEC) or Zone 11
(ATEX) classification mark EEx ia [ia] IIC T6
or Zone 20/21/22, VEGASON 56 also
Zone 1.

• Integrated measured value display in the
sensor or in the external indicating instru­ment which can be mounted up to 25 m
away from the sensor.

2.1 Mounting

Version A

Sensors in version A (flange version) are
supplied completely assembled and ready
for operation. Immediately after mounting on
the vessel and electrical connection, they are
ready for operation.

Version B

Sensors in version B are supplied in two
parts (transducer and sensor electronics).
First of all, mount the transducer on the ves­sel or above the medium. There is a four-pole
jack at the end of the transducer tube. The
respective counterpart to the jack protrudes
out of the lower side of the sensor electron­ics. Insert the plug of the sensor electronics
(only possible in one position) into the jack of
the transducer tube. Continue pushing the
electronics housing onto the transducer tube,
on which there is a wide and a narrow
groove.

Mounting groove (must
no longer be visible after

The wide groove is used for locking the
headless screws. The narrow groove is an
assembly mark. Move the electronics hous­ing farther down over the transducer tube
until the mounting groove is no longer visible.
Fasten the housing with the headless screws
to the transducer tube. Use a 5 mm hexagon
screwdriver (or Allen wrench).

counterpart to the jack is provided in the
connection cylinder of the transducer cable.
Insert the connection cylinder plug into the
jack of the transducer tube. S

On the end of the transducer tube you find a
wide and a narrow groove. The wide groove
is used for locking the cylinder with the head­less screws. The narrow groove is the as­sembly mark.

Then push the connection cylinder onto the
transducer tube (with a slight swivelling mo­tion) until the assembly mark is no longer
visible.

When the assembly mark is covered by the
cylinder, fasten the cylinder with the two
headless screws. Use a 5 mm hexagon
screwdriver (or Allen wrench).

Now mount the sensor electronics at the
requested location. The sensor electronics is
fastened to a mounting bracket so that it can
be mounted on a plain surface or on a wall.
Make sure that the sensor electronics is
mounted in such a way that there is enough
space above the electronics to open the
cover.

Now insert the plug at the other end of the
transducer cable into the jack on the elec­tronics housing.

Note:

Avoid bending the transducer cable too
sharply when laying it out. This is a special
cable which could otherwise be damaged.

In addition, make sure that the cable cannot
be damaged during operation. A signal with
a voltage of approx. 1 kV is transmitted
(which could be a danger in Ex areas if the
cable is damaged) via the shielded cable
cores.

Beam angle and false echoes

At greater distance, the energy of the ultra­sonic impulses distributes over a large area,

The ultrasonic impulses are focused by the
transducers. The impulses leave the trans­ducer in a conical form similar to the beam
pattern of a spotlight. The beam angle is 4°

thus causing weaker echoes from obstruct­ing surfaces. The interfering signals are
therefore less critical than those at close
range.

Therefore, in practical application, the trans­ducer has to be oriented so that the lowest
possible false echo signal strength is
achieved. Only giving attention to the size of
the useful echo is usually not adequate under
difficult measuring conditions. In most cases,
a low false echo level enables the sensor to
reliably pick up the useful echo. With the
adjustment software VVO on the PC, you can
view the echo image (see manual VVO "Sen­sor optimisation".

paraboloidal reflectors. If the transducer is
placed in the focal point of the parabolic tank,
the ultrasonic sensor receives amplified false
echoes. The transducer should be mounted
outside the focal point. Parabolically amplified
echoes can be thereby avoided.

Narrow, uneven shafts, wells and vessel

2.4 Measurement of solids

Flange mounting

For containers with solids, as with applica­tions for liquids, the instrument can be
mounted on a short DIN socket piece. The
transducer end should protrude out of the
socket so that it does not interfere with ultra­sonic signals. The swivelling holder enables
not only correct orientation to the product
surface but also minimisation of possible
false echoes.

Different filling conditions often lead to a vary­ing product surface orientation. This causes
the useful echo to vary in quality. For this
reason, the transducer should be mounted in
such a way that, even in an empty vessel, the
false echo intensity remains as low as possi­ble. You can view the echo curve on the PC
with the adjustment program VVO.

Min. distance

Very good measuring results can be attained
with a measuring tube in continuous narrow
shafts, see illustration. The applied measur­ing tube must have smooth walls inside (e.g.
PE sewage pipe) and a diameter ≥ 200 mm.
This arrangement works well as long as the
inside of the measuring tube collects no dirt
or buildup (cleaning necessary). You might
want to consider using hydrostatic pressure
transmitters or capacitive measuring probes.
The measuring tube should either be never
immersed in the medium, or always im­mersed, making the measurement take place
exclusively in the tube.

Material heaps

2.5 Socket extensions

Ultrasonic sensors require a min. distance to
the liquid or solid. Take the min. distance into
account in your planning. In some situations,
it is possible to reach the required min. dis­tance, and hence the desired filling height
with a socket extension. However, the socket
piece increases the noise level of the ultra­sonic signal at the extension outlet and can
interfere with the measurement. Only use a
socket extension if all other possibilities have
to be excluded. Carry out the extension as
shown in the following illustration.

Socket extensions for liquids

Chamfer and deburr the socket carefully and
make sure that it has a smooth inner surface.
The socket should not protrude into the
measured product, in case buildup can form
on the socket through dirt or product
residues.

For non-adhesive measured products, a
socket extension in the form of a measuring
tube can be permanently submerged in the
product. The ultrasonic measurement is then
made exclusively in the measuring tube and
works very well without interference from
other vessel installations (see "Pump shaft").

Large material heaps are usually measured
with several instruments, which can be
mounted on e.g. traverse cranes. If material
cones form, we recommend orienting the
sensors to the solid surface.

products (figure: VEGASON 54)

2.6 False echoes

The mounting location of the ultrasonic sensor
must be selected such that no installations or
inflowing material are in the path of the ultra­sonic impulses. The following examples and
instructions show the most frequent measur­ing problems and how to avoid them.

Vessel protrusions

Vessel forms with flat protrusions can, due to
their strong false echoes, adversely effect
the measurement. Shields above these flat
protrusions scatter the false echoes and
guarantee a reliable measurement.

Correct Incorrect

Socket extension in solids

For solids, use a conical socket extension
with a taper of at least 15° … 20°.

Vessel protrusions (slope)

Intake pipes, e.g. for the mixing of materials,
with a flat surface directed towards the sen­sor should be covered with a sloping shield.
The shield will scatter the false echo.

Vessel installations

Vessel installations such as, for example, a
ladder, often cause false echoes. Make sure
when planning your measurement loop that
the ultrasonic signals have free access to the
measured product.

Correct Incorrect

Ladder

Ladder

Struts

Struts, like other vessel installations, can
cause strong false echoes that are superim­posed over the useful echo signal. Small
shields effectively hinder a direct false echo
reflection. The false echoes are scattered
and diffused in the area and are then filtered
out as "echo noise" by the measuring elec­tronics.

Inflowing material

Do not mount the instrument in or above the
filling stream. Ensure that you detect the
product surface and not the inflowing mate­rial.

Strong product movements

Strong turbulence in the vessel, e.g. caused
by powerful stirrers or intense chemical reac­tions, seriously interfere with the measure­ment. A surge or bypass tube of sufficient
size (DN 200, DN 250) always allows, pro­vided the product causes no buildup in the
tube, a reliable measurement even with
strong turbulence in the vessel.

2.7 Installation mistakes

Foam generation

Thick foam on the product can cause incor­rect measurements. Take measures to avoid
foam, carry out the measurement in a bypass
tube, or use a different measurement technol­ogy, e.g. capacitive probes or hydrostatic
pressure transmitters.

Wrong orientation to the product

Weak measuring signals are the result if the

Min. distance to the medium

If the min. distance to the medium is not main­tained, the instruments show wrong meas­ured values. Mount the instrument at the

Sensor too close to vessel wall

Correct Incorrect

If the sensor is mounted too close to the
vessel wall (dimension A in diagram), strong
false echoes can be caused. Buildup, rivets,
screws or weld joints on the vessel wall su­perimpose their echoes on the product, i.e.
the useful echo. Please ensure a sufficient
distance from the sensor to the vessel wall
depending on the maximum measuring dis­tance (dimension B in diagram). In case of
good reflecting conditions (liquids, no vessel
installations), we recommend determining the
sensor distance according to Diagram curve

1. At a max. measuring distance of e.g. 10 m,
the distance of the transducer (acc. to curve

1) should be approx. 1.5 m. In case of solids
with poor reflective properties, determine the
distance to the vessel wall according to Dia-
gram curve 2. Under very bad measuring
conditions (rough vessel walls, struts), it
might be necessary to increase the distance
to the vessel wall, or to also filter out the false
echoes by storing them in memory, thereby
adapting the sensor more precisely to the
environment.

Parabolic effects of rounded or arched
vessel tops

Round or parabolic tank tops act like a para­bolic mirror on the signals. If the sensor is
placed at the focal point of such a parabolic

echoes. The optimum location is generally in
the area of half the vessel radius from the
centre.

3 Electrical connection

Electrical connection

3.1 Connection

Safety information – Qualified person­nel

Instruments which are not operated with
protective low voltage or DC voltage must
only be connected by qualified personnel.
This also applies to the configuration of
measuring systems planned for Ex environ­ment.

As a rule, do all connecting work in the com­plete absence of line voltage. Always switch
off the power supply before you carry out
connecting work on the ultrasonic sensors.
Protect yourself and the instruments.

Note, important for connection to an EP
card

If VEGASON 54P … 56P sensors are oper­ated on Profibus input cards (EP cards) in
the VEGALOG 571 processing system, each
card must be powered individually with an
own power supply unit. For power supply of
an EP card, use the power supply unit "ASI­Interface SLA 3.100" from Puls which is avail­able from VEGA.

By this measure, the signal circuits are gal­vanically separated. This avoids possible
crosstalks between the EP cards.

3.2 Connection cables and bus con­figuration

Note the Profibus specification. The connec­tion cables must be specified for the ex­pected operating temperatures in the plant
and must have an outer diameter of
6 … 12 mm, to ensure the seal effect of the
cable entry on the sensor.

For power supply and bus communication, a
two-wire cable acc. to the Profibus specifica­tion (up to max. 2.5 mm2 cross-section area
of conductor) is used. The electrical connec­tion on the sensor is made by spring-loaded
terminals.

In a laboratory setup, a Profibus system will
also work with standard, unshielded two-wire
cable. In practice however, an automation
network and bus system can only be pro­tected reliably against electromagnetic inter­ference with screened cable. Acc. to the
Profibus specification (IEC 1158-2),
screened and twisted cables are prescribed.

All participants are connected in one line
(serially). At the beginning and end of the
bus segment, the bus is terminated by an
active bus termination. On the DP bus level,
most participants already have a bus termi­nation implemented. With more than 32 par­ticipants on the DP level, a so-called repeater
must be used to open and combine another
DP level with a max. of 32 additional partici­pants. On the PA bus branch of the segment
coupler, the PA ultrasonic sensors also work
with a maximum of 32 participants (Ex max.
10 participants).

A PA sensor can work only in conjunction with
a Profibus DP system, to which a Profibus PA
subsystem is connected. A PA Profibus par­ticipant must consume min. 10 mA supply
current.

26 VEGASON 54P … 56P

Electrical connection

Cable length

Connection cables must correspond to the
Profibus specification and the FISCO model.
The sensor cable must be in conformity with
the values of the reference cable acc. to

= 80 … 120 Ω; damping = 3 dB/km;

The max. cable length first of all depends on
the transmission speed:
up to 32 kbit/s: 1900 m Prup to 32 kbit/s: 1900 m Pr

up to 32 kbit/s: 1900 m Pr

up to 32 kbit/s: 1900 m Prup to 32 kbit/s: 1900 m Pr
up to 94 kbit/s: 1200 m Profibus DP
up to 188 kbit/s: 1000 m Profibus DP
up to 500 kbit/s: 500 m Profibus DP
up to 1500 kbit/s: 200 m Profibus DP
up to 12000 kbit/s: 100 m Profibus DP

The distributed resistance of the cable, in
conjunction with the output voltage of the
segment coupler and the current requirement
(VEGASON 10 mA) or the voltage require­ment (VEGASON 9 V) of the sensors, deter­mines the max. length of the cable.

In a practical application of a PA bus branch,
the max. length of the cable is also deter­mined (beside the required supply voltage
and max. current consumption of all partici­pants on the PA bus branch) by the bus
structure and the type of segment coupler
used.

The cable length results from the sum of all
cable sections and the length of all stubs.
The length of the individual stubs must not
exceed the following lengths:
1 … 12 stubs 120 m (Ex: 30 m)
13 … 18 stubs 60 m (Ex: 30 m)
19 … 24 stubs 30 m (Ex: 30 m)

More than 24 stubs are not permitted,
whereby each branch longer than 1.2 m is
counted as a stub. The total length of the
cable must not exceed 1900 m (in Ex version
1000 m).

Ground terminal

The electronics housings of the sensors have
a protective insulation. The ground terminal in
the electronics is galvanically connected with
the metallic process connection. For sensors
with a plastic thread as process fitting, the
sensor must be grounded by connecting a
ground cable to its external ground terminal.

Screening

"Electromagnetic pollution" caused by elec­tronic actuators, energy cables and transmit­ting systems has become so pervasive that
shielding for normal two-wire bus cable is
usually a necessity. According to the Profibus
specification, the screening should be made
on both ends. To avoid potential equalisation
currents, a potential equalisation system
must be provided in addition to the screen­ing.

According to specification, we recommend
the use of twisted and screened two-wire
cable, e.g.: SINEC 6XV1 830-5AH10 (Sie­mens), SINEC L26XV1 830-35H10 (Siemens),
3079A (Belden).

Alternatively, when grounding at both ends in
non-Ex areas, the cable shielding can be
connected on one ground side (in the switch­ing cabinet) via an YC-capacitor (e.g. 10 nF,
1500 V) to the ground potential. Make sure
that the ground connection has the lowest
possible resistance (foundation, plate or
mains earth).

Profibus PA in Ex environment

When used in Ex area, a PA bus with all con­nected instruments must be carried out in
intrinsically safe protection class "i". Four-wire
instruments requiring separate supply must
at least have an intrinsically safe PA connec­tion. VEGA sensors for PA-Ex environment
are generally "ia” two-wire instruments.

VEGASON 54P … 56P 27

Electrical connection

In the so-called Fieldbus Intrinsically Safe
Concept (FISCO), the general conditions for
an Ex safe bus configuration have been laid
down. Therein, the electrical data of the
participants and the bus cable have been
determined, so that the linking of these com­ponents always meets Ex requirements. This
makes the otherwise time-consuming Ex
calculation unnecessary. You can build your
Ex bus according to the IEC standard
1158-2.

The Ex segment coupler delivers a controlled
power supply to the PA bus. It acts as
source in the PA branch. All other compo­nents (field instruments and bus terminators)
are only consumers. A field instrument must
consume at least 10 mA. Ideally, an individual
sensor should not consume more than
10 mA, so that the number of instruments can
be as large as possible.

VEGA PA sensors, whether Ex or non Ex,
consume a constant current of 10 mA. Ac­cording to the Profibus specification, this is
the minimum participant current. With VEGA
sensors it is therefore possible to connect 10
sensors (also in Ex environment) even with a
limited energy supply from the Ex segment
couplers.

Watch out for potential losses

Due to potential transfer, earthing on both
sides without a potential equalisation system
is not allowed in Ex applications. If an instru­ment is used in hazardous areas, the re­quired regulations, conformity and type
approval certificates for systems in Ex areas
must be noted (e.g. DIN 0165). Please also
note the approval documents with the safety
data sheet attached to the Ex sensors.

3.3 Sensor address

In a Profibus system composed of Profibus
DP and Profibus PA subsystem, each partici­pant must have a unique address. Each
participant, whether master or slave, is
accessed by means of its own address in
the bus system. The address of a partici­pant, whether on DP or PA level, should be
assigned before connecting to the bus, be­cause an address can be used only once. If
an address is used twice, interference in the
bus will be caused.

The address of an ultrasonic sensor can be
set in two ways:

- with the adjustment software VVO (soft­ware addressing) or

- with the DIP switch block in the sensor
(hardware addressing).

VEGA Profibus sensors are delivered with
the address set at 126 (all DIP switches to
"ON").
Remember, in a Profibus system there are
max. 126 participants possible. When the
DIP switch is set to address 126 (or higher),
the address can be adjusted with the adjust­ment software VVO, the adjustment module
MINICOM or another configuration tool (e.g.
PDM). However, there can be only one sen­sor on the bus with address 126 (delivery
status) during address assignment via soft­ware. For that reason, hardware addressing
(DIP switch) before connection to the bus is
recommended.

Hardware addressing

The DIP switches generate an address
number in the binary system. This means
that, from right to left (ascending), any switch
represents a number twice as high as the
previous switch on the right. The corre­sponding number in the decimal system
results from the sum of all switches set to
"ON". In the illustration, you see the decimal
number that corresponds to each individual
DIP switch.

DIP switch 8 corresponds to the number 128,
switch 1 corresponds to the number 1 and
switch 3 corresponds to the decimal number

4.

sensor lid with the optional indication display
can then be opened. Unscrew the sleeve nut
and slip it over the connection cable (after
removing about 10 cm of insulation). The

3.6 Bus configuration

The type of ultrasonic sensor you use de­pends on the process requirements and
mounting conditions, as well as on the re­quirements of your control, regulative, or
process control system.

VEGASON 54 … 56 Profibus sensors are
sensors for use in Profibus PA environment.
Profile 3 has been implemented in the sen­sors. A measuring system consists of one or
several sensors, one or several segment
couplers and one DP master computer, such
as e.g. a S7 PLC with Profibus interface or a
process control system with Profibus DP­Master-Slot. The processing unit, e.g. the
PLC, evaluates the level-proportional, digital
measuring signals in a number of evaluation
routines and puts them to use process-spe­cifically.

On the following four pages you will see
schematic illustrations of the bus configura­tion.

The automation system as Master-Class 1
takes over the complete bus control. It reads
out all signals cyclically and, if necessary,
gives instructions to the participants (e.g.
sensors). Additional master systems (e.g.
visualisation systems or adjustment tools)
can also be connected to the DP bus. These
systems operate as so-called Master-Class 2
participants. Like the Master-Class 1 system,
they can read out signals, give instructions
and operate in the acyclical mode.

Each participant on the bus must have an
unambiguous address. The addressing
covers both bus levels. A Profibus DP net­work can have max. 126 participants, includ­ing all participants on the PA level. In
practice, each Master-Class 1 computer gets
address 1 and the Master-Class 2 comput­ers address 10 … 20. As a rule, the slaves or
participants get the addresses 21 … 126. On
the Profibus PA network segment, a max. of
32 sensors can be connected on one PA
segment coupler.

Ex environment

In Ex environment, intrinsically safe (EEx ia)
PA sensors are used with Ex segment cou­plers. Generally, the number of PA sensors
on a segment coupler (Ex or non Ex) de­pends on the current requirement of the
sensors and on the current supplied by the
segment coupler. Segment couplers for
EEx ia environment provide 90 … 110 mA.
The number of sensors results from the sum
of:

- the basic current intake of all sensors

- plus 9 mA communication signal

- plus the leakage currents of all sensors

- plus a recommended current reserve
(approx. 10 mA)

A DP bus does not allow power supply via
signal cable, whereas the PA bus does. Both,
DP and PA, require at least one screened
two-wire cable. The DP bus can additionally
have up to 8 cores (screened), some of
which can be supply cables (see also "Instal­lation Guides PA + DP" of the Profibus User
Organisation (PNO).

4.1 Adjustment media

Adjustment with PACTware

Setup

TM

In chapter "1.4 Adjustment" the Profibus ad­justment scheme was briefly explained and
the adjustment media for VEGA Profibus
sensors were shown. All VEGA Profibus
sensors operate in profile 3 and can be ad­justed with:

- the adjustment program VVO on a PC with
Profibus card

- the adjustment program PACTwareTM, under
which VVO runs as a subprogram

- the Siemens software PDM in conjunction
with an EDD (Electronic-Device-Descrip­tion)

- the adjustment module MINICOM in the
sensor.

Adjustment with VV O on the PC

The adjustment program VVO enables user­friendly adjustment of VEGA Profibus PA
sensors. All functions and options relating to
the sensor adjustment are accessible. The
program runs under Windows® on a PC with
a Profibus-Master-Class 2 interface card on
Profibus DP level as Master-Class 2 tool. The
VVO program accesses the VEGA PA sen­sors via the DP bus, the segment coupler
and the PA bus.

The adjustment with PACTwareTM corre­sponds to VVO adjustment. In this case,
VVO runs as a subprogram of PACTwareTM.
The adjustment instructions can be found in
the documentation of PACTwareTM.

Adjustment with PDM

The sensors can be adjusted completely with
PDM. However, some convenient functions
and many special features, like e.g. display
of an echo curve, are not available. In addi­tion to the PDM software, an EDD (available
upon request from VEGA) is required for
each sensor type. The adjustment instruc­tions for PDM are described in the PDM
documentation.

Adjustment with the adjustment module
MINICOM

With the adjustment module MINICOM, you
adjust the individual sensor directly in the
sensor or in the external indicating instrument
VEGADIS 50. The adjustment module
MINICOM enables (with the 6-key adjustment
field with text display) all essential functions
of parameter setting and adjustment.

Note:

Please note that for adjustment with VVO,
version 2.70 or higher is required.

Setup

4.2 Adjustment with the PC

The instructions for the adjustment with the
PC and the adjustment program VVO can be
found in the manual "VEGA Visual Operating
(VVO)" which is supplied with the latest ad­justment software.

Beside the adjustment of ultrasonic sensors,
the manual "VEGA Visual Operating (VVO)"
also describes the setup of all other VEGA
sensors with the PC.

4.3 Adjustment with the adjustment module MINICOM

In addition to the PC, you can adjust the
sensor with the small, detachable adjustment
module MINICOM. The adjustment module is
plugged into the sensor or into the external
indicating instrument (optional).

Although the volume of information of the
small display cannot be compared with that
of the adjustment program VVO, you will be
able to carry out your settings quickly and
efficiently with the small MINICOM.

9. Outputs
Below you will find short explanations to
setup steps 1 … 9.

3. Operating range

Without special adjustment, the operating
range corresponds to the measuring range.
The measuring range was already entered
with the min./max. adjustment. Generally, it is
useful to choose a slightly wider range
(approx. 5 %) for the operating range than
for the measuring range.

Example:
Min./Max. adjustment: 0.300 … 5.850 m;
adjust operating range to approx.

0.250 … 6.000 m.

You can carry out the adjustment with or

the adjustment without medium, as you can
then adjust without a filling/emptying cycle.

2. Measurement in gases

Adjustment is only necessary if the measure­ment is made in gases other than air (CO2,
He, etc.). When measuring in gases, sound

Enter the max. adjustment (upper product

Note:

The difference between the adjustment val­ues of the lower product distance and the
upper product distance should be as big as
possible, preferably at 0 % and 100 %. If the
values are very close together, e.g. lower
product distance adjustment at 40 %
(3.102 m) and upper product distance ad­justment at 45 % (3.331 m), the measurement
will be inaccurate. A characteristics curve is
generated from the two points. Even the
smallest deviations between actual product
distance and entered product distance will
considerably influence the slope of the char­acteristics curve. If the adjustment points are
too close together, small errors inflate to
considerably larger ones when the 100 % or
the 0 % value is outputted.

Ampl.: means amplitude of the level echo in

dB (useful level)

S-N: means Signal-Noise, i.e. the useful

level minus the level of the back­ground noise

The bigger the "S-N" value (difference be­tween the amplitudes of the useful signal level
and the noise level), the better the measure­ment:
> 50 dB Measurement excellent
40 … 50 dB Measurement very good
20 … 40 dB Measurement good
10 … 20 dB Measurement satisfactory
5 … 10 dB Measurement sufficient
< 5 dB Measurement poor

Example:

Ampl. = 68 dB
S-N = 53 dB

68 dB – 53 dB = 15 dB noise level

A signal distance of 53 dB means a very high
degree of measurement reliability.

5.3 Parameter listing

The following parameter listing and function
diagram is used for setup with the automation
system if there is no adjustment software
available. The listing reflects the parameters
of the function block and the transducer
block and should only be used by experi­enced Profibus technicians. Please make
sure that all VEGA sensors are Profile 3 sen­sors. As a rule, however, you will carry out
the sensor setup more conveniently with the
VEGA adjustment software VVO or with the
adjustment module MINICOM in the sensor.

The PA parameters and the function diagram
are normally not required for setup and serve
only to deepen the knowledge of the inter­ested user and enable him to read in the
sensor measured values into the processing
system without an adjustment tool.

6 Diagnosis

Diagnosis

6.1 Simulation

To simulate a certain filling, you can call up
the function "Simulation" on the adjustment
module MINICOM or in the software program
VVO.

With this function, you simulate a real vessel
filling level. Please note that connected instru­ments, such as e.g. a PLC, react according
to their adjustments and will probably acti­vate alarms or system functions.

Simulation with VVO

If you start the simulation mode with the ad­justment program VVO on the PC, the simu­lated level is outputted until you quit the
simulation mode.

Simulation with MINICOM

If you start the simulation mode on the adjust­ment module MINICOM, the sensor returns to
standard operating mode after one hour.

6.2 Error codes

Error codes Corrective measure

E013 No valid measured value Message is displayed during the warm-up

- Sensor in the warm-up phase phase

- Loss of the useful echo If the message remains, a false echo storage
(with the adjustment software on the PC - see
"Echo curve" under "Sensor optimisation") must
be carried out together with a modification of
mounting location and orientation to achieve the
lowest possible false echo background.

E017 Adjustment span too small Carry out a readjustment.

E036 Sensor software does not run Sensor requires a software update (service).

E040 Hardware failure/Electronics defec- Check all connection cables.
