3.2 Principle of operation

The VEGAPULS 61 is a radar sensor for continuous level measurement of liquids under simple process conditions.

The instrument is ideal also for all applications in the water and waste water industry. It is particularly suitable for level measurement in water treatment, in pump stations as well as storm water overflow tanks, for flow measurement in open flumes and for gauge measurement.

The antenna of the radar sensor emits short radar pulses with a duration of approx. 1 ns. These pulses are reflected 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.

4.1 General instructions

On instruments with process fitting thread, the hexagon must be tightened with a suitable wrench. For the proper wrench size see chapter

"Dimensions".

Warning:

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

Protection against moisture

Protect your instrument against moisture ingress through the following measures:

•

Use the recommended cable (see chapter "Connecting to power

supply")

•

Tighten the cable gland

When mounting horizontally, turn the housing so that the cable gland points downward

•

Loop the connection cable downward in front of the cable gland

This applies particularly to:

•

Outdoor mounting

Installations in areas where high humidity is expected (e.g. through cleaning processes)

•

Installations on cooled or heated vessels

Suitability for the process conditions

Make sure that all parts of the instrument exposed to the process are suitable for the existing process conditions.

These are mainly:

•

Active measuring component

Process fitting

Process seal

Process conditions are particularly:

•

Process pressure

Process temperature

Chemical properties of the medium

•

Abrasion and mechanical influences

You can find detailed information on the process conditions in chapter

"Technical data" as well as on the type label.

4.2 Collar or adapter flange

For mounting the instrument on a socket, a combi compression flange for DN 80 (ASME 3" or JIS 80) is also available for retro fitting. Optionally, the instrument can be also equipped with an adapter flange from

DN 100 (ASME 4" or JIS 100).

With the housing versions plastic, aluminium single chamber and stainless steel, the collar flange can be placed directly over the housing. With the aluminium double chamber housing, retroactive mount-

You can find drawings of these mounting options in chapter "Dimen-

sions".

Fig. 2: Flange mounting of the radar sensor

4.3 Mounting preparations, mounting strap

The mounting strap enables simple mounting on the vessel wall or silo top. It is suitable for wall, ceiling or boom mounting. Especially in open vessels this is a very easy and effective way to align the sensor to the bulk solid surface.

The strap is supplied unassembled and must be screwed to the sensor before setup with three hexagon socket screws M5 x 10 and spring washers. Max. torque, see chapter "Technical data". Required tools: Allen wrench size 4.

There are two ways to screw the strap onto the sensor. Depending on the selected version, the sensors can be swivelled in the strap as follows:

•

Single chamber housing

– Angle of inclination 180°, infinitely variable

– Angle of inclination in three steps 0°, 90° and 180°

•

Double chamber housing

– Angle of inclination 90°, infinitely variable

– Angle of inclination in two steps 0° and 90°

Polarisation

Fig. 4: Turning by fastening in the centre

4.4 Mounting instructions

For tight installation of the version with plastic horn antenna with compression or adapter flange, the following conditions must be fulfilled:

1. Use suitable flat seal, e.g. of EPDM with Shore hardness 25 or 50

2. Make sure the number of flange screws corresponds to the number of flange holes

3. Tighten all screws with the torque stated in the technical data

The emitted radar impulses of the radar sensor are electromagnetic waves. The polarisation is the direction of the electrical wave component. By turning the instrument in the connection flange or mounting boss, the polarisation can be used to reduce the effects of false echoes.

The position of the polarisation is marked on the process fitting of the instrument.

When mounting the sensor, keep a distance of at least 200 mm

(7.874 in) to the vessel wall. If the sensor is installed in the center of dished or round vessel tops, multiple echoes can arise. These can, however, be suppressed by an appropriate adjustment (see chapter

"Setup").

If you cannot maintain this distance, you should carry out a false signal storage during setup. This applies particularly if buildup on the vessel wall is expected. In such cases, we recommend repeating the false signal storage at a later date with existing buildup.

In liquids, direct the sensor as perpendicular as possible to the product surface to achieve optimum measurement results.

Vessel installations

Fig. 13: Alignment in liquids

The mounting location of the radar sensor should be a place where no other equipment or fixtures cross the path of the microwave signals.

Vessel installations, such as e.g. ladders, limit switches, heating spirals, struts, etc., can cause false echoes and impair the useful echo.

Make sure when planning your measuring point that the radar sensor has a "clear view" to the measured product.

In case of existing vessel installations, a false echo storage should be carried out during setup.

If large vessel installations such as struts or supports cause false echoes, these can be attenuated through supplementary measures.

Small, inclined sheet metal baffles above the installations scatter the radar signals and prevent direct interfering reflections.

Agitators

Fig. 14: Cover flat, large-area profiles with deflectors

If there are agitators in the vessel, a false signal storage should be carried out with the agitators in motion. This ensures that the interfering reflections from the agitators are saved with the blades in different positions.

Fig. 15: Agitators

Foam generation

Measurement in a surge pipe

Through the action of filling, stirring and other processes in the vessel, compact foams that considerably damp the emitted signals may form on the product surface.

If foams are causing measurement errors, the biggest possible radar antennas, the electronics with increased sensitivity or low frequency radar sensors (C band) should be used.

As an alternative, sensors with guided microwave can be used. These are unaffected by foam generation and are best suited for such applications.

4.5 Measurement setup - Pipes

By using a surge pipe in the vessel, the influence of vessel installations and turbulence can be excluded. Under these prerequisites, the measurement of products with low dielectric values (ε possible.

Measurement in the bypass tube

4 Mounting

Constructive requirements:

•

Material metal, smooth inner surface

Preferably pultruded or straight beaded stainless steel tube

Welded joint should be straight and lie in one axis with the holes

•

Flanges are welded to the tube according to the orientation of the polarisation

•

When using a ball valves, align the transitions on the inside and fix accurately

•

Gap size with junctions ≤ 0.1 mm

Surge pipes must extend all the way down to the requested min. level, as measurement is only possible within the tube

•

Diameter of holes ≤ 5 mm, any number OK, on one side or completely through

•

The antenna diameter of the sensor should correspond to the inner diameter of the tube

•

Diameter should be constant over the complete length

Instructions for surge pipe extension:

•

The ends of the extension tubes must be bevelled and exactly aligned

•

Welded connection via external U profiles according to illustration above. Length of the U profiles should be at least double the tube diameter

•

Do not weld through the pipe wall. The surge pipe must remain smooth inside. Roughness and beads on the inside caused by unintentional penetration should be removed since they cause strong false echoes and encourage buildup

•

An extension via welding neck flanges or pipe collars is not recommended.

An alternative to measurement in a surge pipe is measurement in a bypass tube outside of the vessel.

Safety instructions

5 Connecting to power supply

5 Connecting to power supply

5.1 Preparing the connection

Always keep in mind the following safety instructions:

Warning:

Connect only in the complete absence of line voltage.

•

The electrical connection must only be carried out by trained personnel authorised by the plant operator.

•

If overvoltage surges are expected, overvoltage arresters should be installed.

Voltage supply

Power supply and current signal are carried on the same two-wire cable. The operating voltage can differ depending on the instrument version.

The data for power supply are specified in chapter "Technical data".

Provide a reliable separation between the supply circuit and the mains circuits according to DIN EN 61140 VDE 0140-1.

Keep in mind the following additional influences on the operating voltage:

•

Lower output voltage of the power supply unit under nominal load

(e.g. with a sensor current of 20.5 mA or 22 mA in case of fault)

•

Influence of additional instruments in the circuit (see load values in chapter "Technical data")

Connection to signal conditioning instruments

The signal conditioning instruments VEGAMET and VEGASCAN have digital sensor recognition. When connecting VEGAPULS 61, an up-to-date version of the signal conditioning instrument software is required. For a software update go to "www.vega.com/downloads" and "Software".

Connection cable

The instrument 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 for instruments with housing and cable gland. To ensure the seal effect of the cable gland (IP protection rating), find out which cable outer diameter the cable gland is suitable for.

Use a cable gland fitting the cable diameter.

We generally recommend the use of screened cable for HART multidrop mode.

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 required, we recommend connecting the cable screen on both ends to ground potential. In the sensor, the screen



Connection technology

Connection procedure

must be connected directly to the internal ground terminal. The ground terminal on the outside of the housing must be connected to the ground potential (low impedance).

In Ex systems, the grounding is carried out according to the installation regulations.

In electroplating and CCP systems (cathodic corrosion protection) it must be taken into account that significant potential differences exist.

This can lead to unacceptably high currents in the cable screen if it is grounded at both ends.

Information:

The metallic parts of the instrument (process fitting, 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 find specifications on the potential connections inside the instrument in chapter "Technical data".

5.2 Connecting

The voltage supply and signal output are connected via the springloaded terminals in the housing.

Connection to the display 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 reinserting the terminal block, you should hear it snap in.

Proceed as follows:

1. Unscrew the housing cover

2. If a display and adjustment module is installed, remove it by turning it slightly to the left.

3. Loosen compression nut of the cable entry gland

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

28

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

Information:

Solid cores as well as flexible cores with wire end sleeves are inserted directly into the terminal openings. In case of flexible cores without end sleeves, press the terminal from above with a small screwdriver, the terminal opening is then free. When the screwdriver is released, the terminal closes again.

You can find 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



Electronics and terminal compartment

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

10. Reinsert the display and adjustment module, if one was installed

11. Screw the housing cover back on

The electrical connection is finished.

The instrument is adjusted via the four keys of the display and adjustment module. The LC display indicates the individual menu items. The functions of the individual keys are shown in the above illustration.

Approx. 60 minutes after the last pressing of a key, an automatic reset to measured value indication is triggered. Any values not confirmed with [OK] will not be saved.

6.3 Parameter adjustment

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

The main menu is divided into five sections with the following functions:

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 instrument status, pointer, measurement reliability, simulation, echo curve

Further settings: Instrument unit, false signal suppression, linearisation curve, reset, date/time, reset, copy function

Info: Instrument name, hardware and software version, date of manufacture, instrument features

Information:

In this operating instructions manual, the instrument-specific 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".



Setup - Medium

You can find in the operating instructions manual "Display and adjust-

ment module" also the description of the menu sections "Display" and

"Info".

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

Each medium has different reflection properties. With liquids, further interfering factors are fluctuation 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 different measuring conditions, the selection "Liquid" or "Bulk solid" should be made in this menu item.

Setup - Application

Through this selection, the sensor is adapted perfectly to the product and measurement reliability, particularly in products with poor reflective 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.

In addition to the medium, also the application, i.e. the measuring site, can influence the measurement.

With this menu item, the sensor can be adapted to the applications.

The adjustment possibilities depend on the selection "Liquid" or "Bulk

solid" under "Medium".

The following options are available when "Liquid" is selected:

The selection "Standpipe" opens a new window in which the inner diameter of the applied standpipe is entered.

Through this selection, the sensor is adapted optimally to the application or the location and measurement reliability under the various basic conditions is increased considerably.


With this selection, the operating range of the sensor is adapted to the vessel height and the reliability with different frame conditions is increased considerably.

The min. adjustment must be carried out independently of this.

Setup - Vessel form


Also the vessel form can influence the measurement apart from the medium and the application. To adapt the sensor to these measurement conditions, this menu item offers you different options for vessel bottom and ceiling in case of certain applications.

Setup - Adjustment


Since the 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, see the following example:

44



0,5 m (19.68

Setup - Min. adjustment

Fig. 36: Parameter adjustment example min./max. adjustment

1 Min. level = max. meas. distance

2 Max. level = min. meas. distance

3 Reference plane

If these values are not known, an adjustment with the distances of for example 10 % and 90 % is possible. Starting point for these distance specifications is always the seal surface of the thread or flange. You can find specifications of the reference plane in chapter "Technical

data". 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.

Proceed as follows:

1. Select the menu item "Setup" with [->] and confirm with [OK].

Now select with [->] the menu item "Min. adjustment" and confirm 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.



Setup - Max. adjustment

4. Enter the suitable distance value in m for the empty vessel (e.g. distance from the sensor to the vessel bottom) corresponding to the percentage value.

5. Save settings with [OK] and move with [ESC] and [->] to the max. adjustment.

Proceed as follows:

1. Select with [->] the menu item "Max. adjustment" and confirm 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.

Diagnosis - Peak 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

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

46



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 detailed statement of the reliability.

The selected curve is continuously updated. A submenu with zoom functions is opened with the [OK] key:

•

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

"Y-Zoom": 1, 2, 5 and 10x signal magnification in "dB"

•

"Unzoom": Reset the presentation to the nominal measuring range without magnification

Diagnostics - Echo curve memory

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 reflections and can influence 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 in the level measurement.

This should be done with a low level so that all potential interfering reflections can be detected.

Proceed as follows:

1. Select with [->] the menu item "False signal suppression" and confirm with [OK].

2. Confirm again with [OK].

3. Confirm again with [OK].

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

48

5. All interfering signals in this section are detected by the sensor and stored after confirming 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 a false signal. The level would then no longer be detectable in this area.

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

suppression":

Delete: An already created false signal suppression will be completely deleted. This is useful if the saved false signal suppression no longer matches the metrological conditions in the vessel.

Extend: is used to extend an already created false signal suppression. This is useful if a false signal suppression was carried out with



Additional adjustments -

Linearization curve

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.

A linearisation 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 - and the indication or output of the volume is required. Corresponding linearisation 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".

Additional adjustments

- Reset

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 instruments with appropriate approval are used as part of an overfill protection system according to WHG:

If a linearisation curve is selected, the measuring signal is no longer necessarily linear to the filling height. This must be considered by the user especially when adjusting the switching point on the limit signal transmitter.

With a reset, certain parameter adjustments carried out by the user are reset.

The following reset functions are available:

Delivery status: Restoring the parameter settings at the time of shipment from the factory incl. the order-specific settings. A created false signal suppression, user-programmable linearization curve as well as the measured value memory will be deleted.

Basic settings: Resetting of the parameter settings, incl. special parameters, to the default values of the respective instrument. Any stored false signal suppression or user programmable linearisation curve, as well as the measured value memory, is 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 linearisation curve, measured value memory as well as event memory remain untouched. The linearisation 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, measured value: Resetting of the measured min. and max. distances to the actual measured value.

The following table shows the default values of the instrument. Depending on the instrument version, not all menu items are available or some may be differently assigned:

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 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 adjustment module are saved:

•

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

In the menu "Additional adjustments" the items "Sensor-specific

units, temperature unit and linearization"

•

The values of the user programmable linearization 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 display 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".

Prerequisites

7 Setup with PACTware such cases, the interface converter can be connected parallel to the

4 … 20 mA cable (dashed line in the previous illustration).

7.2 Parameter adjustment

For parameter adjustment of the instrument via a Windows PC, the configuration software PACTware and a suitable instrument driver

(DTM) according to FDT standard are required. The latest 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 firmware 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.

Standard/Full version

Fig. 39: Example of a DTM view

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 configuration simplifies 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


7 Setup with PACTware 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.com/downloads and "Software". The full version is available on CD from the agency serving you.

7.3 Saving the parameter adjustment data

We recommend documenting or saving the parameter adjustment data via PACTware. That way the data are available for multiple use or service purposes.

9 Diagnosis, asset management and service

9.1 Maintenance

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

Measured value memory

Event memory

Echo curve memory

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.

Up to 100,000 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 reliability 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:

•

Modification of a parameter

Switch-on and switch-off 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:

•

PC with PACTware/DTM

Control system with EDD

•

Display and adjustment module

Control system with EDD

9.3 Asset Management function

The instrument features self-monitoring and diagnostics according to NE 107 and VDI/VDE 2650. In addition to the status messages in the following tables there are more detailed error messages available under the menu item "Diagnostics" via the display and adjustment module, PACTware/DTM and EDD.

The status messages are divided into the following categories:

•

Failure

Function check

Out of specification

•

Maintenance requirement and explained by pictographs:

1 2 3 4

Fig. 40: Pictographs of the status messages

1 Failure - red

2 Out of specification - yellow

3 Function check - orange

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 specification: The measured value is unstable because the instrument specification is exceeded (e.g. electronics temperature).


Maintenance: Due to external influences, the instrument function is limited. The measurement is affected, 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).

9.4 Rectify faults

The operator of the system is responsible for taking suitable measures to rectify faults.

The first measures are:

•

Evaluation of fault messages, for example via the display and

• adjustment module

Checking the output signal

Treatment of measurement errors

Further comprehensive diagnostics options are available with a PC with PACTware and the suitable DTM. In many cases, the reasons can be determined in this way and faults rectified.

60


Check the 4 … 20 mA signal

Treatment of measurement errors with liquids


Connect a multimeter 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:

Error

4 … 20 mA signal not stable

4 … 20 mA signal missing

Current signal greater than

22 mA or less than 3.6 mA

Cause

– Fluctuations of the measured variable

– Electrical connection faulty

– Voltage supply missing

– Operating voltage too low or load resistance too high

– Electronics module in the sensor defective

Rectification

– Set damping according to the instrument via the display and adjustment module or PACTware/

DTM

– Check connection according to chapter "Connection steps" and if necessary, correct according to chapter "Wiring plan"

– Check cables for breaks; repair if necessary

– Check, adapt if necessary

– Exchange the instrument or send it in for repair

The below tables show typical examples of application-related measurement errors with liquids. The measurement errors are differentiated according to the following:

•

Constant level

Filling

•

Emptying

The images in column "Error pattern" show the real level with a broken line and the level displayed by the sensor as a continuous line.

time

Notes:

•

Wherever the sensor displays a constant value, the reason could

• also be the fault setting of the current output to "Hold value"

If the level indication is too low, the reason could be a line resistance that is too high



Measurement error with constant level

Fault description

1. Measured value shows a too low or too high level

2. Measured value jumps towards 0 %

3. Measured value jumps towards 100 %

Error pattern

0 time

Cause

– Min./max. adjustment not correct

– Incorrect linearization curve

– Installation in a bypass tube or standpipe, hence running time error (small measurement error close to 100 %/large error close to 0 %)

Rectification

– Adapt min./max. adjustment

– Adapt linearization curve

– Check parameter "Application" with respect to vessel form, adapt if necessary (bypass, standpipe, diameter)

0 time

– Multiple echo (vessel top, product surface) with amplitude higher than the level echo

– Check parameter "Application", especially vessel top, type of medium, dished bottom, high dielectric constant, and adapt if necessary

– Carry out a false signal suppression

0 time

– Due to the process, the amplitude of the level echo sinks

– A false signal suppression was not carried out

– Amplitude or position of a false signal has changed (e.g. condensation, buildup); false signal suppression no longer matches actual conditions

– Determine the reason for the changed false signals, carry out false signal suppression, e.g. with condensation

Measurement error during filling


4. Measured value remains unchanged during filling

5. Measured value remains in the bottom section during filling

6. Measured value remains momentarily unchanged during filling and then jumps to the correct level

Error pattern Cause

0 time

– False signals in the close range too big or level echo too small

– Strong foam or spout generation

– Max. adjustment not correct

0 time

– Echo from the tank bottom larger than the level echo, for example, with products with

ε r

< 2.5 oil-based, solvents

Rectification

– Eliminate false signals in the close range

– Check measurement situation:

Antenna must protrude out of the socket, installations

– Remove contamination on the antenna

– In case of interferences due to installations in the close range:

Change polarisation direction

– Create a new false signal suppression

– Adapt max. adjustment

– Check parameters Medium,

Vessel height and Floor form, adapt if necessary

– Turbulence on the product surface, quick filling

– Check parameters, change if necessary, e.g. in dosing vessel, reactor

0 time

7. Measured value jumps towards 0 % during filling

8. Measured value jumps towards 100 % during filling

9. Measured value jumps sporadically to

100 % during filling

10. Measured value jumps to ≥ 100 % or

0 m distance

Error pattern

0

0

0 time time time

Cause

– Amplitude of a multiple echo

(vessel top - product surface) is larger than the level echo

– The level echo cannot be distinguished from the false signal at a false signal position (jumps to multiple echo)

Rectification

– Check parameter "Application", especially vessel top, type of medium, dished bottom, high dielectric constant, and adapt if necessary



– Chose a more suitable installation position

– Carry out a false signal suppression

– Due to strong turbulence and foam generation during filling, the amplitude of the level echo sinks. Measured value jumps to the false signal

– Varying condensation or contamination on the antenna

– Carry out a false signal suppression or increase false signal suppression with condensation/contamination in the close range by editing

0 time

– Level echo is no longer detected in the close range due to foam generation or false signals in the close range. The sensor goes into overfill protection mode. The max. level (0 m distance) as well as the status message "Overfill protection" are outputted.

– Check measuring site: Antenna must protrude out of the socket


– Use a sensor with a more suitable antenna

Measurement error during emptying


11. Measured value remains unchanged in the close range during emptying


– False signal larger than the level echo

– Level echo too small

0 time

12. Measured value jumps towards 0 % during emptying

0 time

– Echo from the tank bottom larger than the level echo, for example, with products with

ε r

< 2.5 oil-based, solvents

Rectification

– Eliminate false signal in the close range. Check: Antenna must protrude from the socket




– After removing the false signals, the false signal suppression must be deleted. Carry out a new false signal suppression

– Check parameters Type of medium, Vessel height and

Floor form, adapt if necessary




13. Measured value jumps sporadically towards 100 % during emptying

Reaction after fault rectification


– Varying condensation or contamination on the antenna

24 hour service hotline

time

Rectification

– Carry out false signal suppression or increase false signal suppression in the close range by editing

– With bulk solids, use radar sensor with purging air connection

Depending on the reason for the fault and the measures taken, the steps described in chapter "Setup" must be carried out again or must be checked for plausibility and completeness.

Should these measures not be successful, please call in urgent cases the VEGA service hotline under the phone no. +49 1805 858550.

The hotline is also available outside normal working hours, seven days a week around the clock.

Since we offer this service worldwide, the support is provided in

English. The service itself is free of charge, the only costs involved are the normal call charges.

9.5 Exchanging the electronics module

If the electronics module is defective, it can be replaced by the user.

In Ex applications, only instruments and electronics modules with appropriate 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 differ 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, first of all the order data must be downloaded from the Internet (see operating instructions manual "Electronics

module").

Caution:

All user-specific settings must be entered again. Hence, you have to carry out a new setup after the electronics exchange.

If you have stored the data of the parameter adjustment during the first setup of the sensor, you can transfer these to the replacement electronics module. A new setup is no more necessary.

9.6 Software update

The following components are required to update the instrument software:
