3.2 Principle of operation

The instrument is suitable for applications with liquids in storage tanks
and process vessels under dicult process conditions. Application
possibilities can be found in the chemical industry, in environmental
and recycling technology as well as in the petrochemical industry.

The version with standpipe antenna is particularly suitable for
measurement of solvents and liquid gases, for vessels with foam
generation or for measurement of products with low dielectric values
(DK > 1.6).

Measurement in a standpipe is not recommended for extremely
adhesive products.

The standard electronics enables the use of instruments in products
with an ε
enables the use of the instrument also in applications with very poor
reective properties or products with an εr value ≥1.5. The values that
can be actually reached depend on the measurement conditions, the
antenna system or the standpipe or bypass tube.

Functional principle

Packaging

10

The antenna of the radar sensor emits short radar pulses with a
duration of approx. 1 ns. These pulses are reected by the product
and received by the antenna as echoes. The transit time of the radar
pulses from emission to reception is proportional to the distance and
hence to the level. The determined level is converted into an appropri­ate output signal and outputted as measured value.

3.3 Packaging, transport and storage

Your instrument was protected by packaging during transport. Its

capacity to handle normal loads during transport is assured by a test
according to DIN EN 24180.

The packaging of standard instruments consists of environment­friendly, recyclable cardboard. For special versions, PE foam or PE

4.1 General instructions

With instruments with threaded process tting, suitable tools must be

applied for tightening the hexagon.

Warning:

The housing must not be used to screw the instrument in! Applying
tightening force can damage internal parts of the housing.

Moisture

Suitability for the process
conditions

Installation

Use the recommended cables (see chapter "Connecting to power
supply") and tighten the cable gland.

You can give your instrument additional protection against moisture
penetration by leading the connection cable downward in front of the
cable entry. Rain and condensation water can thus drain o. This ap­plies mainly to outdoor mounting as well as installation in areas where
high humidity is expected (e.g. through cleaning processes) or on
cooled or heated vessels.

Make sure that all parts of the instrument exposed to the process, in
particular the active measuring component, process seal and process
tting, are suitable for the existing process conditions. These include
above all the process pressure, process temperature as well as the
chemical properties of the medium.

You can nd the specications in chapter "Technicaldata" and on the
type label.

4.2 Instructions for installation

By using the standpipe version, the inuence of turbulence and ves­sel installations, such as e.g. heating spirals or agitators, is excluded.
If turbulence or vigorous product movement occurs in the vessel, long
standpipe antennas should be fastened to the vessel wall.

The standpipe antenna must extend all the way down to the request­ed min. level, as measurement is only possible within the tube. If a
good mixing of the product is important, you should use a version with
perforated surge pipe.

Warning:

Remember that with the version with ¾" thread, a max. torque of
80 Nm (59 lbf ft) must not be exceeded.

Safety instructions

5 Connecting to power supply

5.1 Preparing the connection

Always keep in mind the following safety instructions:

Connect only in the complete absence of line voltage

•

If overvoltage surges are expected, overvoltage arresters should

•

be installed

Voltage supply via mains
voltage

Voltage supply via low
voltage

Select connection cable

Cable gland ½ NPT

In this case, the instrument is designed in protection class II. To main­tain this protection class, it is absolutely necessary that the ground
conductor be connected to the internal ground terminal. Take note of
the general installation regulations.

Supply voltage and current output are carried on separate connection
cables if reliable separation is required. The supply voltage range can
dier depending on the instrument version.

The data for power supply are specied in chapter "Technicaldata".

In this case, the instrument is designed in protection class II. Gener­ally connect the instrument to vessel ground (potential equalization)
or with plastic vessels to the next ground potential. For this purpose, a
ground terminal is located laterally on the instrument housing.

An approved, three-wire installation cable with PE conductor is
required for voltage supply with mains voltage.

The 4 … 20 mA current output is connected with standard two-wire
cable without screen. If electromagnetic interference is expected
which is above the test values of EN 61326-1 for industrial areas,
screened cable should be used.

Use cable with round cross-section. A cable outer diameter of
5 … 9 mm (0.2 … 0.35 in) ensures the seal eect of the cable gland.
If you are using cable with a dierent diameter or cross-section,
exchange the seal or use a suitable cable gland.

With plastic housing, the NPT cable gland or the Conduit steel tube

must be screwed without grease into the threaded insert.
Max. torque for all housings see chapter "Technicaldata"

Cable screening and
grounding

14

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 on the
outside of the housing must be connected to the potential equalisa­tion (low impedance).

If potential equalisation currents are expected, the connection on the
processing 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 eect against high frequency interfer­ence signals remains.

Connection technology

5 Connecting to power supply

Warning:

Signicant potential dierences exist inside galvanization plants as
well as on vessels with cathodic corrosion protection. Considerable
equalisation currents can ow over the cable screen if the screen is
grounded on both ends.

To avoid this in such applications, the cable screen must be connect­ed to ground potential only at one end (in the switching cabinet). The
cable screen must not be connected to the internal ground terminal in
the sensor and the outer ground terminal on the housing must not be
connected to the potential equalisation!

Information:

The metal parts of the instrument (process tting, transmitter, concen­tric tube, etc.) are conductively connected with the inner and outer
ground terminal on the housing. This connection exists either directly
via connecting metallic parts or, in case of instruments with external
electronics, via the screen of the special connection cable.

You can nd specications on the potential connections inside the
instrument in chapter "Technicaldata".

5.2 Connecting

The voltage supply and signal output are connected via the spring-

loaded terminals in the housing.
The connection to the indicating and adjustment module or to the

interface adapter is carried out via contact pins in the housing.

Information:

The terminal block is pluggable and can be removed from the elec­tronics. To do this, lift the terminal block with a small screwdriver and
pull it out. When inserting the terminal block again, you should hear it
snap in.

Connection procedure

36508-EN-121011

VEGAPULS 62 standpipe version • 4 … 20 mA/HART - four-wire

Proceed as follows:

1. 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.

Adjustment system

Main menu

The sensor is adjusted via the four keys of the indicating and adjust-

ment module. The LC display indicates the individual menu items. The
functions of the individual keys are shown in the above illustration.
Approx. 10 minutes after the last pressing of a key, an automatic reset
to measured value indication is triggered. Any values not conrmed
with [OK] will not be saved.

6.3 Parameter adjustment

Through the parameter adjustment the instrument is adapted to the
application conditions. The parameter adjustment is carried out via an
adjustment menu.

The main menu is divided into ve sections with the following func-

tions:

Setup: Settings, e.g., for measurement loop name, medium, applica­tion, vessel, adjustment, signal output

Display: Settings, e.g., for language, measured value display, lighting
Diagnosis: Information, e.g. on the instrument status, pointer, reli-

ability, simulation, echo curve
Further settings: Instrument unit, false signal suppression, linearisa-

tion curve, reset, date/time, reset, copy function
Info: Instrument name, hardware and software version, calibration

date, instrument features

Information:

In this operating instructions manual, the instrument-specic param­eters in the menu sections "Setup", "Diagnosis" and "Additional set-
tings" are described. The general parameters in these menu section
are described in the operating instructions manual "Indicating and
adjustment module".

6 Set up with the indicating and adjustment module

You can nd in the operating instructions manual "Indicating and ad-
justment module" also the description of the menu sections "Display"
and "Info".

In the main menu point "Setup", the individual submenu points should
be selected subsequently and provided with the correct parameters
to ensure the optimum adjustment of the measurement. The proce­dure is described in the following.

Setup/Medium

Setup/Adjustment

Each medium has dierent reection properties. With liquids, further
interfering factors are uctuation product surface and foam genera­tion. With bulk solids, these are dust generation, material cone and
additional echoes from the vessel wall.

To adapt the sensor to these dierent measuring conditions, the
selection "Liquid" or "Bulk solid" should be made in this menu item.

Through this selection, the sensor is adapted perfectly to the product
and measurement reliability, particularly in products with poor reec­tive properties, is considerably increased.

Enter the requested parameters via the appropriate keys, save your
settings with [OK] and jump to the next menu item with the [ESC] and
the [->] key.

Since a radar sensor is a distance measuring instrument, the distance
from the sensor to the product surface is measured. For indication of
the real level, an allocation of the measured distance to the percent­age height must be carried out.

To perform the adjustment, enter the distance with full and empty ves­sel. For instruments with standpipe antenna, these values are already
preset by default, see the following example:

Fig.10:Parameteradjustmentexamplemin./max.adjustment

1 Min. level = max. meas. distance
2 Max. level = min. meas. distance

If these values are not known, an adjustment with the distances of for
example 10 % and 90 % is possible. Starting point for these distance
specications is always the seal surface of the thread or ange. By
means of these settings, the real level will be calculated.

The real product level during this adjustment is not important, be­cause the min./max. adjustment is always carried out without chang­ing the product level. These settings can be made ahead of time
without the instrument having to be installed.

Setup/Min. adjustment

Proceed as follows:

1. Select the menu item "Setup" with [->] and conrm with [OK].
Now select with [->] the menu item "Min. adjustment" and conrm
with [OK].

2. Edit the percentage value with [OK] and set the cursor to the
requested position with [->].

3. Set the requested percentage value with [+] and save with [OK].
The cursor jumps now to the distance value.

adjustment.

Setup/Max. adjustment

Diagnosis/Peak value

Proceed as follows:

1. Select with [->] the menu item max. adjustment and conrm with
[OK].

2. Prepare the percentage value for editing with [OK] and set the
cursor to the requested position with [->].

3. Set the requested percentage value with [+] and save with [OK].
The cursor jumps now to the distance value.

4. Enter the appropriate distance value in m (corresponding to the
percentage value) for the full vessel. Keep in mind that the max.
level must lie below the min. distance to the antenna edge.

5. Save settings with [OK]

The respective min. and max. measured value is saved in the sensor.

The values are displayed in the menu item "Peak values".

Diagnosis/Measurement
reliability

24

When non-contact level sensors are used, the measurement can be

inuenced by the respective process conditions. In this menu item,
the measurement reliability of the level echo is displayed as dB value.
The measurement reliability equals signal strength minus noise. The
higher the value, the more reliable the measurement. With a function­ing measurement, the values are > 10 dB.

36508-EN-121011

6 Set up with the indicating and adjustment module

Diagnoses/Curve indica­tion

The "Echocurve" shows the signal strength of the echoes over the

measuring range in dB. The signal strength enables an evaluation of
the quality of the measurement.

The "False signal suppression" displays the saved false echoes (see
menu "Additional settings") of the empty vessel with signal strength in
"dB" over the measuring range.

A comparison of echo curve and false signal suppression allows a
more accurate conclusion on measurement reliability. The selected
curve is continuously updated. With the [OK] key, a submenu with
zoom functions is opened:

"X-Zoom": Zoom function for the meas. distance

•

"Y-Zoom": 1, 2, 5 and 10x signal magnication in "dB"

•

"Unzoom": Reset the presentation to the nominal measuring range

•

36508-EN-121011

VEGAPULS 62 standpipe version • 4 … 20 mA/HART - four-wire

With the function "Echocurvememory" the echo curve can be saved

at the time of setup. This is generally recommended; for using the As­set Management functions it is absolutely necessary. If possible, the
curve should be saved with a low level in the vessel.

With the adjustment software PACTware and the PC, the high resolu­tion echo curve can be displayed and used to recognize signal
changes over the operating time. In addition, the echo curve of the
setup can be also displayed in the echo curve window and compared
with the actual echo curve.

Additional adjustments/
False signal suppression

The following circumstances cause interfering reections and can

inuence the measurement:

High sockets

•

Vessel installations such as struts

•

Agitators

•

Buildup or welded joints on vessel walls

•

Note:

A false signal suppression detects, marks and saves these false sig­nals so that they are no longer taken into account for level measure­ment.

This should be done with the low level so that all potential interfering
reections can be detected.

Proceed as follows:

1. Select the menu item "Additional settins" with [->] and conrm
with [OK]. With [->] you have to select the menu item "False
signal suppression" and conrm with [OK].

2. Conrm again with [OK].

3. Conrm again with [OK].

26

4. Conrm again with [OK] and enter the actual distance from the
sensor to the product surface.

5. All interfering signals in this section are detected by the sensor
and stored after conrming with [OK].

Note:

Check the distance to the product surface, because if an incorrect
(too large) value is entered, the existing level will be saved as false
signal. The lling level would then no longer be detectable in this area.

36508-EN-121011

6 Set up with the indicating and adjustment module

If a false signal suppression has already been created in the sensor,
the following menu window appears when selecting "False signal
suppression":

The menu item "Delete" is used to completely delete an already cre­ated false signal suppression. This is useful if the saved false signal
suppression no longer matches the metrological conditions in the
vessel.

The menu item "Extend" is used to extend an already created false
signal suppression. This is useful if a false signal suppression was
carried out with a too high level and not all false signals could be de­tected. When selecting "Extend", the distance to the product surface
of the created false signal suppression is displayed. This value can
now be changed and the false signal suppression can be extended to
this range.

Additional adjustments/
Linearization curve

A linearization is necessary for all vessels in which the vessel volume
does not increase linearly with the level - e.g. in a horizontal cylindri­cal or spherical tank - and the indication or output of the volume is
required. Corresponding linearization curves are preprogrammed
for these vessels. They represent the correlation between the level
percentage and vessel volume.

By activating the appropriate curve, the volume percentage of the
vessel is displayed correctly. If the volume should not be displayed in
percent but e.g. in l or kg, a scaling can be also set in the menu item
"Display".

Enter the requested parameters via the appropriate keys, save your
settings and jump to the next menu item with the [ESC] and [->] key.

Caution:

Note the following if the instrument with corresponding approval is
used as part of an overll protection system according to WHG:

If a linearisation curve is selected, the measuring signal is no longer
linearly proportional to the level. This must be taken into consideration
by the user, particularly when setting the switching point on the level
switch.

- Reset

With radar sensors with standpipe antenna, the sensor length is

already preset in this menu item. When shortening the standpipe
antenna afterwards, this value must be appropriately corrected.

When a reset is carried out, all settings (with only a few exceptions)

are reset. The exceptions are: PIN, language, lighting, SIL and HART
mode.

The following reset functions are available:
Delivery status: Restoring the parameter settings at the time of ship-

ment from the factory incl. the order-specic settings. A created false
signal suppression, user-programmable linearization curve as well as
the measured value memory will be deleted.

Basic settings: Resetting the parameter settings incl. special and
laboratory parameters to the default values of the respective instru­ment. A created false signal suppression, user programmable lineari­zation curve as well as the measured value memory will be deleted.

Setup: Resetting of the parameter settings to the default values of the
respective instrument in the menu item Setup. User-generated false
signal suppression, user-programmed linearization curve, measured
value memory as well as event memory remain untouched. The
linearization is set to linear.

False signal suppression: Deleting a previously created false signal
suppression. The false signal suppression created in the factory
remains active.

Peak values distance: Resetting the measured min. and max. dis­tances to the actual measured value.

6.4 Saving the parameter adjustment data

We recommended noting the adjusted data, e.g. in this operating
instructions manual, and archiving them afterwards. They are thus
available for multiple use or service purposes.

If the instrument is equipped with an indicating and adjustment
module, the data in the sensor can be saved in the indicating and
adjustment module. The procedure is described in the operating
instructions manual "Indicating and adjustment module" in the menu
item "Copy sensor data". The data remain there permanently even if
the sensor power supply fails.

The following data or settings for adjustment of the indicating and
adjustment module are saved:

All data of the menu "Setup" and "Display"

•

In the menu "Additional adjustments" the items "Sensor-specic

•

units, temperature unit and linearization"
The values of the user programmable linearisation curve

•

The function can also be used to transfer settings from one instru­ment to another instrument of the same type. If it is necessary to
exchange a sensor, the indicating and adjustment module is inserted
into the replacement instrument and the data are likewise written into
the sensor via the menu item "Copy sensor data".

necessary. This applies, e.g. to the VEGA instruments VEGATRENN
149A, VEGAMET 381 and VEGAMET 391). Commercially available
Ex separators are also usually equipped with sucient current limita­tion resistance. In such cases, VEGACONNECT 4 can be connected
parallel to the 4 … 20 mA cable.

7.2 Parameter adjustment with PACTware

For parameter adjustment of the sensor via a Windows PC, the con­guration software PACTware and a suitable instrument driver (DTM)
according to FDT standard are required. The up-to-date PACTware
version as well as all available DTMs are compiled in a DTM Collec­tion. The DTMs can also be integrated into other frame applications
according to FDT standard.

Note:

To ensure that all instrument functions are supported, you should
always use the latest DTM Collection. Furthermore, not all described
functions are included in older rmware versions. You can download
the latest instrument software from our homepage. A description of
the update procedure is also available in the Internet.

Further setup steps are described in the operating instructions manu­al "DTMCollection/PACTware" attached to each DTM Collection and
which can also be downloaded from the Internet. Detailed descrip­tions are available in the online help of PACTware and the DTMs.

All device DTMs are available as a free-of-charge standard version
and as a full version that must be purchased. In the standard version,
all functions for complete setup are already included. An assistant for
simple project conguration simplies the adjustment considerably.
Saving/printing the project as well as import/export functions are also
part of the standard version.

In the full version there is also an extended print function for complete
project documentation as well as a save function for measured value
and echo curves. In addition, there is a tank calculation program as
well as a multiviewer for display and analysis of the saved measured
value and echo curves.

The standard version is available as a download under www.vega.

9.1 Maintenance

If the device is used correctly, no maintenance is required in normal
operation.

9.2 Measured value and event memory

The instrument has several memories which are available for diagno­sis purposes. The data remain even with voltage interruption.

Measured value memory

Event memory

Echo curve memory

Up to 60,000 measured values can be stored in the sensor in a ring
memory. Each entry contains date/time as well as the respective
measured value. Storable values are for example:

Distance

•

Filling height

•

Percentage value

•

Lin. percent

•

Scaled

•

Current value

•

Meas. reliability

•

Electronics temperature

•

When the instrument is shipped, the measured value memory is
active and stores distance, measurement certainty and electronics
temperature every 3 minutes.

The requested values and recording conditions are set via a PC with
PACTware/DTM or the control system with EDD. Data are thus read
out and also reset.

Up to 500 events are automatically stored with a time stamp in the
sensor (non-deletable). Each entry contains date/time, event type,
event description and value. Event types are for example:

Modication of a parameter

•

Switching on and o times

•

Status messages (according to NE 107)

•

Error messages (according to NE 107)

•

The data are read out via a PC with PACTware/DTM or the control
system with EDD.

The echo curves are stored with date and time and the corresponding

echo data. The memory is divided into two sections:
Echo curve of the setup: This is used as reference echo curve for

the measurement conditions during setup. Changes in the measure­ment conditions during operation or buildup on the sensor can thus
be recognized. The echo curve of the setup is stored via:

4 Maintenance - blue

Failure: Due to a malfunction in the instrument, a failure message is
outputted.

This status message is always active. It cannot be deactivated by the
user.

Function check: The instrument is in operation, the measured value
is temporarily invalid (for example during simulation).

This status message is inactive by default. It can be activated by the
user via PACTware/DTM or EDD.

Outofspecication: The measured value is unstable because the
instrument specication is exceeded (e.g. electronics temperature).

This status message is inactive by default. It can be activated by the
user via PACTware/DTM or EDD.

Maintenance: Due to external inuences, the instrument function
is limited. The measurement is aected, but the measured value is
still valid. Plan in maintenance for the instrument because a failure is
expected in the near future (e.g. due to buildup).

This status message is inactive by default. It can be activated by the
user via PACTware/DTM or EDD.

9.4 Rectify faults

The operator of the system is responsible for taking suitable meas-

ures to rectify faults.

The rst measures are:

Evaluation of fault messages, for example via the indicating and

•

adjustment module
Checking the output signal with 4 … 20 mA instruments

•

Treatment of measurement errors

•

Further comprehensive diagnostics options oer a PC with the soft­ware PACTware and the suitable DTM. In many cases, the reasons
can be determined in this way and faults can be rectied.

Connect a handmultimeter in the suitable measuring range according
to the wiring plan. The following table describes possible errors in the
current signal and helps to remove them:

The propagation speed of the radar impulses in gas or vapour above the medium is reduced by
high pressure. This eect depends on the superimposed gas or vapour and is especially large at
low temperatures.
