Quick start

2. In the menu item "Medium - Dielectric constant" you can dene the medium type (medium).

3. Carry out the adjustment in the menu items "Min. adjustment" and "Max. adjustment".

4. A "Linearization" is required for all vessels in which the vessel vol-

ume does not increase linearly with the level - e.g. in a horizontal cylindrical or spherical tank. Activate the appropriate curve.

5. A "False signal suppression" detects, marks and saves the false signals so that they are no longer taken into account for level

measurement. We generally recommend a false signal suppression.

Parameterization example

The sensor measures the distance from the sensor (reference plane) to the product surface.

Fig. 3: Measuring ranges - VEGAFLEX 82

1 Reference plane 2 Probe length L 3 Measuring range 4 Upper dead band (in this area no measurement is possible) 5 Lower dead band (in this area no measurement is possible)

For this adjustment, the distance is entered when the vessel is full and nearly empty. If these values are not known, an adjustment with

other distances, for example, 10 % and 90 % is also possible. Starting

point for these distance specications is always the seal surface of the thread or ange.

Further steps

1. In the menu "Additional settings", menu item "Damping" you can adjust the requested damping of the output signal.

3.2 Principle of operation

The VEGAFLEX 82 is a level sensor with cable or rod probe for continuous level measurement, suitable for applications in bulk solids.

High frequency microwave pulses are guided along a steel cable or a rod. Upon reaching the product surface, the microwave pulses are reected. The running time is evaluated by the instrument and outputted as level.

Probe end tracking

To increase sensitivity, the probe is equipped with probe end tracking. In products with a low dielectric constant, this function is very helpful.

This is the case, for example, in plastic granules, packing chips or in

uidized vessels. Between a dielectric constant of 1.5 and 3, the function switches on, if

required. As soon as the level echo can no longer be detected, probe end tracking is automatically activated. The measurement is contin-

ued with the last calculated dielectric constant.

The accuracy thus depends on the stability of the dielectric constant.

If you measure a medium with a dielectric constant below 1.5, probe end tracking is always active. In this case, you have to enter the dielectric constant of the medium. A stable dielectric constant is very

important here.

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

Protective caps

Suitability for the process conditions

Installation position

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

•

installations in areas where high humidity is expected (e.g. through

•

cleaning processes)

installations on cooled or heated vessels

•

In the case of instrument housings with self-sealing NPT threads, it is

not possible to have the cable entries screwed in at the factory. The openings for the cable glands are therefore covered with red protective caps as transport protection.

Prior to setup you have to replace these protective caps with approved cable glands or close the openings with suitable blind plugs.

The suitable cable glands and blind plugs come with the instrument.

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

nameplate.

4.2 Instructions for installation

Mount VEGAFLEX 82 in such a way that the distance to vessel installations or to the vessel wall is at least 300 mm (12 in). In non-metallic vessels, the distance to the vessel wall should be at least 500 mm

(19.7 in).

During operation, the probe must not touch any installations or the

vessel wall. If necessary, fasten the probe end. In vessels with conical bottom it can be advantageous to mount the

sensor in the center of the vessel, as measurement is then possible

nearly down to the lowest point of the bottom. Keep in mind that measurement all the way down to the tip of the probe may not be pos-

sible. The exact value of the min. distance (lower dead band) is stated

in chapter "Technical data".

Fig. 5: Vessel with conical bottom

Type of vessel

Plastic vessel/Glass vessel

The guided microwave principle requires a metal surface on the process tting. Therefore use in plastic vessels etc. an instrument version with ange (from DN 50) or place a metal sheet (ø > 200 mm/8 in) beneath the process tting when screwing it in.

Make sure that the plate has direct contact with the process tting. When installing rod or cable probes without metal vessel wall, e.g.

in plastic vessels, the measured value can be inuenced by strong electromagnetic elds (emitted interference according to EN 61326:

class A).

Use a probe in coax version for applications in liquids.

Socket

If possible, avoid sockets. Mount the sensor ush with the vessel top.

If this is not possible, use short sockets with small diameter.

Higher sockets or sockets with a bigger diameter can generally be used. They simply increase the upper blocking distance. Check if this

is relevant for your measurement.

In such cases, always carry out a false signal suppression after instal-

lation. You can nd further information under "Setup procedure".

Welding work

Inowingmedium

Measuring range

Before beginning the welding work, remove the electronics module from the sensor. By doing this, you avoid damage to the electronics through inductive coupling.

Do not mount the instruments in or above the lling stream. Make sure that you detect the product surface, not the inowing product.

Fig.10:Mountingofthesensorwithinowingmedium

The reference plane for the measuring range of the sensors is the

sealing surface of the thread or ange.

Keep in mind that a min. distance must be maintained below the reference plane and possibly also at the end of the probe - measurement in these areas is not possible (dead band). The length of the cable

can be used all the way to the end only when measuring conductive

products. These blocking distances for dierent mediums are listed

in chapter "Technical data". Keep in mind for the adjustment that the default setting for the measuring range refers to water.

Pressure

Fixing

od extensions

The process tting must be sealed if there is gauge or low pressure in

the vessel. Before use, check if the seal material is resistant against

the measured product and the process temperature.

The max. permissible pressure is specied in chapter "Technical data" or on the type label of the sensor.

If there is a danger of the cable probe touching the vessel wall during operation due to product movements or agitators etc., the measuring probe should be securely xed.

In the gravity weight there is an internal thread (M12), e.g. for an eye-

bolt (optional) - (article no. 2.27423).

Make sure that the probe cable is not completely taut. Avoid tensile

loads on the cable.

Avoid undened vessel connections, i.e. the connection must be either grounded reliably or isolated reliably. Any undened change of

this requirement can lead to measurement errors.

In case of dicult installation conditions, for example in a socket, the probe can be adapted respectively with a rod extension.

Let the probe length determine automatically by the instrument to compensate the resulting running time changes.

You can nd further information in the supplementary instructions of

the rod extension.

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

Connection cable

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 signal 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. Gener-

ally 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.

For instruments with housing and cable gland, use cable with round

cross-section. To ensure the seal eect of the cable gland (IP protection rating), you have to check for which cable outer diameter the

cable gland is suitable.

5 … 9 mm (0.20 … 0.35 in)

•

6 … 12 mm (0.24 … 0.47 in)

•

10 … 14 mm (0.40 … 0.55 in)

•

Use a cable gland tting the cable diameter.

Cable gland ½ NPT

Cable screening and grounding

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".

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 interfer-

ence signals remains.

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 connect-

ed 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 metallic 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 Connection

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

loaded terminals in the housing.

The connection to the display and adjustment module or to the inter-

face 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

41830-EN-130314

VEGAFLEX 82 • 4 … 20 mA/HART - four-wire

Proceed as follows:

1. Unscrew the housing cover

2. If a display and adjustment module is installed, remove it by turn-

ing 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) of insulation from the ends of the individual wires

5. Insert the cable into the sensor through the cable entry

5 Connecting to power supply

Fig. 11: Connection steps 5 and 6

6. Insert the wire ends into the terminals according to the wiring plan

Information:

Solid cores as well as exible cores with wire end sleeves are inserted directly into the terminal openings. In case of exible cores without end sleeves, press the terminal head with a small screwdriver; the terminal opening is freed. When the screwdriver is released, the

terminal closes again.

You can nd further information on the max. wire cross-section under

"Technical data/Electromechanical data"

7. Check the hold of the wires in the terminals by lightly pulling on them

8. Connect the screen to the internal ground terminal, connect the outer ground terminal to potential equalisation

9. Tighten the compression nut of the cable entry. The seal ring must completely encircle the cable

10. Place probably existing display and adjustment module back on

11. Screw the housing cover back on

The electrical connection is hence nished.

Min. adjustment - Interface

Carry out the min. adjustment for the interface.

To do this, enter the percentage value and the suitable distance value in m for the empty vessel.

Linearization

A linearization is necessary for all vessels in which the vessel volume does not increase linearly with the level - e.g. a horizontal cylindrical or spherical tank, when 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.

The linearization applies for the measured value indication and the current output. By activating the suitable curve, the percentage vessel volume is displayed correctly.

False signal suppression

High sockets and internal vessel installations cause interfering reections and can inuence the measurement.

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

interface measurement. We generally recommend carrying out a false

signal suppression to achieve the best possible accuracy. This should be done with the lowest possible level so that all potential interfering reections can be detected.

Enter the actual distance from the sensor to the product surface.

All interfering signals in this section are detected by the sensor and stored.

The following circumstances cause interfering reections and can

inuence the measurement:

High sockets

•

Vessel installations such as struts

•

Deectors, etc.

•

Note:

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

ment.

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

Proceed as follows:

you can enter special parameters. In exceptional cases, individual parameters can be modied in order to adapt the sensor to special

requirements.

Change the settings of the special parameters only after having contacted our service sta.

The sensor oers the HART modes "Analogue current output" and

"Fix current (4 mA)". In this menu item you determine the HART mode and enter the address with Multidrop mode.

In the mode "Fixed current output" up to 63 sensors can be operated on one two-wire cable (Multidrop operation). An address between 0 and 63 must be assigned to each sensor.

If you select the function "Analogue current output" and also enter an address number, you can output a 4 … 20 mA signal in Multidrop mode.

With the mode "

Fixed current (4 mA)" a xed 4 mA signal is outputted

independently of the actual level.

6.5 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 a display and adjustment module,

the data in the sensor can be saved in the display and adjustment

module. The procedure is described in the operating instructions manual "Display 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 display and ad-

justment module are saved:

Prerequisites

Note:

With power supply units with integrated HART resistance (internal

resistance approx. 250 Ω), an additional external resistance is not

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 limita-

tion 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 descrip-

tions are available in the online help of PACTware and the DTMs.

False signal suppression

With this function you can carry out the automatic false signal suppression. We recommend carrying out false signal suppression in any case.

Step 7 of 7 Additional settings

When the setup of the instrument is nished, additional settings can

be made. These are various backups and the locking of the instrument against unauthorised or inadvertent adjustment.

Prepareabackupleoftheinstrumentparameteradjustment?

For backup purposes, the current parameter adjustment of the instru-

ment is stored in a le. You can use this le later on to restore the

instrument parameter adjustment. The complete data set is down-

loaded from the device. This procedure can last several minutes.

Createinstrumentdocumentation?

This function is used to print or create a PDF le of the current parameter adjustment. To read the PDF le, you need a suitable program (for example Acrobat Reader). To print or create the PDF le, all data are downloaded from the device. For this function, the full version of the DTM Collection is required. This procedure can last several

minutes.

Storeechocurveofthesetupinthesensor?

Have you completed the initial setup of the instrument? In such case, we recommend storing the current signal conditions in the device for

later instrument tests and diagnostics.

LockadjustmentwithPINaftersetting?

The instrument is locked with the current PIN. A parameter adjustment is possible only after the PIN is entered again.

7.4 Saving the parameter adjustment data

with respective Ex approval may be used. If there is no electronics module available on site, the electronics

module can be ordered through the agency serving you. The electronics modules are adapted to the respective sensor and dier in signal output or voltage supply.

The new electronics module must be loaded with the default settings of the sensor. These are the options:

In the factory

•

Or on site by the user

•

In both cases, the serial number of the sensor is needed. The serial numbers are stated on the type label of the instrument, on the inside

of the housing as well as on the delivery note. When loading on site, rst of all the order data must be downloaded

from the Internet (see operating instructions manual "Electronics module").

Exchanging the cable/rod

9.6 Exchange or shorten cable/rod

The cable or rod (meas. part) of the probe can be shortened, if neces-

sary. To loosen the rod or cable you need a fork spanner with spanner width 13.

1. Loosen the rod or cable by applying a fork spanner to the at surfaces (SW 13), provide counterforce with another fork spanner

(SW 13)

2. Unscrew the loosened rod or cable manually.

3. Place the enclosed new double washer onto the thread.

Caution:

Make sure that the two components of the double washer remain together.

4. Screw the new rod and the new cable manually to the thread on

the process tting.

5. Exert counterforce with the second fork spanner and tighten the or or cable on the at surfaces with a torque of 15 Nm (11 lbf ft).

Shorten cable/rod

Fig. 32: Exchange cable or rod

Information:

Please keep the stated torque so that the max. tensile strength remains.

The rod or cable of the probe can be shortened individually.

1. Mark the requested length with mounted measuring rod.

2. Cable: Loosen the three pins on the gravity weight Cable ø 4: 6 hexagon 3 Cable ø 6, cable ø 8: hexagon 4

3. Cable: remove the pins

4. Cable: Pull the cable out of the gravity weight

5. Shorten the cable/rod with a cut-o wheel or metal saw at the marking. Take note of the specications in the following illustration

when shortening the cable.

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.

The following table shows the resulting deviation for some typical gases and vapours. The specied values refer to the distance. Positive values mean that the measured distance is too large, negative values that the measured distance is too small.
