3.2 Principle of operation

The VEGAPULS 65 is a radar sensor for continuous measurement of liquids under simple process conditions. It is particularly suitable for level measurement in vessels with small process fittings and under simple process conditions.

The instrument can be used with products with an ε antenna system, the standpipe or bypass.

r

value ≥1.8. The actually achievable value depends on the measuring conditions, the

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.

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 based on ISO 4180.

The packaging of standard instruments consists of environmentfriendly, recyclable cardboard. For special versions, PE foam or PE foil is also used. Dispose of the packaging material via specialised recycling companies.

Transport must be carried out in due consideration of the notes on the transport packaging. Nonobservance of these instructions can cause damage to the device.

The delivery must be checked for completeness and possible transit damage immediately at receipt. Ascertained transit damage or concealed defects must be appropriately dealt with.

4.1 General instructions

On devices with a threaded fitting, the hexagon on the process fitting must be tightened with a suitable wrench.

See chapter " Dimensions " for wrench size.

Warning:

The housing or the electrical connection may not be used for screwing in! Tightening can cause damage, e. g. to the rotation mechanism of the housing.

Protection against moisture

Protect your instrument against moisture ingress through the following measures:

• Use a suitable connection cable (see chapter " power supply ")

Connecting to

• Tighten the cable gland or plug connector

When mounting horizontally, turn the housing so that the cable

• gland or plug connector point downward

Lead the connection cable downward in front of the cable entry or plug connector.

This applies mainly to outdoor installations, in areas where high humidity is expected (e.g. through cleaning processes) and on cooled or heated vessels.

To maintain the housing protection, make sure that the housing lid is closed during operation and locked, if necessary.

Make sure that the degree of contamination specified in chapter

" Technical data " meets the existing ambient conditions.

Suitability for the process conditions

Make sure before mounting 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 in particular are:

• 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.

Suitability for the ambient conditions

The instrument is suitable for standard and extended ambient conditions acc. to IEC/EN 61010-1.

4.2 Mounting instructions

The PTFE washer of the antenna encapsulation serves also as process seal.

After a certain time under the effect of large temperature changes,

PTFE plated flanges tend to lose their pre-tensioning. To compensate for this, disc springs must be used with the flange screws.

We recommended using elastic washers or detent-edged washers:

Note:

We recommend re-tightening the screws at regular intervals, depending on process pressure and temperature. Recommended torque, see chapter " Technical data ", " Torques ".

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.

Installation position

Fig. 3: Position of the polarisation

1 Marking hole

When mounting the VEGAPULS 65, keep a distance of at least

500 mm (19.69 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 suppression during setup. This applies particularly if buildup on the vessel wall is expected. In such cases, we recommend repeating the false signal suppression at a later date with existing buildup.

(19.69")

Fig. 4: Mounting of the radar sensor on round vessel tops

In vessels with conical bottom it can be advantageous to mount the sensor in the centre of the vessel, as measurement is then possible down to the bottom.


4 Mounting

Inflowing medium

Fig. 5: Mounting of the radar sensor on vessels with conical bottom

Do not mount the instruments in or above the filling stream. Make sure that you detect the product surface, not the inflowing product.

Mounting socket

Fig. 6: Mounting of the radar sensor with inflowing medium

The active part of the antenna, i.e. the conical antenna part should protrude completely out of the socket.

To meet the different socket dimensions, sensors for socket lengths up to 50, 100 and 250 mm (2, 4, 10 in) are available.


4 Mounting

Sensor orientation

Fig. 7: Recommended socket mounting

In case of very big socket diameters, the active antenna part can be slightly recessed in the socket. The following rule applies to the standard version of VEGAPULS 65: Socket diameter corresponds to max. socket height.

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

Vessel installations

Fig. 8: 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 radar 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 signal suppression 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.


4 Mounting

Agitators

Fig. 9: Cover flat, large-area profiles with deflectors

If there are agitators in the vessel, a false signal suppression 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.

Foam generation

Fig. 10: Agitators

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

If foam is causing measurement errors, the largest possible radar antenna 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 ap plications.

5 Connecting to power supply

5.1 Preparing the connection

Always keep in mind the following safety instructions:

• Carry out electrical connection by trained, qualified personnel authorised by the plant operator

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

Warning:

Connect only in the complete absence of line voltage.

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.

Power the instrument via an energy-limited circuit acc. to IEC 61010-

1, e.g. via Class 2 power supply unit.

Keep in mind the following additional factors that influence the operat ing 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 ")

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.

Make sure that the cable used has the required temperature resistance and fire safety for max. occurring ambient temperature

Use cable with round cross section for instruments with housing and cable gland. Use a cable gland suitable for the cable diameter to ensure the seal effect of the cable gland (IP protection rating).

Metric threads

In the case of instrument housings with metric thread, the cable glands are screwed in at the factory. They are sealed with plastic plugs as transport protection.

You have to remove these plugs before electrical connection.

NPT thread

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


Cable screening and grounding

5 Connecting to power supply free openings for the cable glands are therefore covered with red dust protection 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.

On plastic housings, the NPT cable gland or the Conduit steel tube must be screwed into the threaded insert without grease.

Max. torque for all housings, see chapter " Technical data ".

If screened cable is required, we recommend connecting the cable screening on both ends to ground potential. In the sensor, the cable screening 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 plants as well as plants for 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, sensor, concen tric tube, etc.) are connected with the internal and external ground terminal on the housing. This connection exists either directly via the conductive 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 ".

Connection technology

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.

Connection procedure Proceed as follows:

1. Unscrew the housing lid

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 gland and remove blind plug

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

When the [OK] and [ESC] keys are pressed simultaneously for more than 5 s, the display returns to the main menu. The menu language is then switched over to " English ".

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 Measured value indication - Selection of national language

With the [->] key you move between three different indication modes.



In the first view, the selected measured value is displayed in large digits.

In the second view, the selected measured value and a corresponding bar graph presentation are displayed.

In the third view, the selected measured value as well as a second selectable value, e.g. the temperature of the electronics, are displayed.

Selection of national language

During the initial setup of an instrument shipped with factory settings, use the " OK " key to get to the menu " National language ".

This menu item is used to select the national language for further parameter adjustment. You can change the selection via the menu item

" Setup - Display, Menu language ".

Main menu

With the " OK " key you move to the main menu.

6.4 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 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 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 pa rameters in the menu sections " Setup ", " Diagnosis " and " Additional settings " are described. The general parameters in these menu sections are described in the operating instructions manual " Display and adjustment module ".



Setup - Measurement loop name

In the operating instructions manual " Display and adjustment module " you can also find the description of menu sections " Display " and

" Info ".

In the main menu item " Setup ", the individual submenu items 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.

In the menu item " Sensor TAG " you edit a twelve-digit measurement loop designation.

You can enter an unambiguous designation for the sensor, e.g. the measurement loop name or the tank or product designation. In digital systems and in the documentation of larger plants, a singular designation must be entered for exact identification of individual measuring points.

The available digits include:

• Letters from A … Z

Numbers from 0 … 9

Special characters +, -, /, -

Setup - Medium Every medium has different reflective properties. With liquids, there are additional interfering factors such as turbulent product surface and foam generation. With bulk solids, the additional interfering factors are dust generation, angle of repose and secondary 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

30

Through this selection, the sensor is optimally adapted to the product, and measurement reliability, particularly in products with poor reflec tive 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.

Following the characteristics of the applications and the metrological features of the sensor are described.

Caution:

If liquids with different dielectric constants separate in the vessel, for example through condensation, the radar sensor can detect under certain circumstances only the medium with the higher dielectric constant. Keep in mind that layer interfaces can cause faulty measurements.

If you want to measure the total height of both liquids reliably, please contact our service department or use an instrument specially designed for interface measurement.

Apart from the medium and the application, the vessel form itself can influence the measurement. To adapt the sensor to these measuring conditions, this menu item offers different options for vessel bottom and ceiling for certain applications.

Setup - Vessel height, measuring range


Through this selection the operating range of the sensor is adapted to the vessel height, which considerably increases measurement reliability under different basic conditions.

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

Setup - Adjustment


Since the radar sensor is a distance measuring instrument, it is the distance from the sensor to the product surface that is measured. To indicate the actual level, the measured distance must be assigned to a certain height percentage.

To perform the adjustment, enter the distance with full and empty vessel, see the following example:



3

100% 2

0% 1

Setup - Min. adjustment

Fig. 26: Parameterisation example, Min./max. adjustment

1 Min. level = max. measuring distance

2 Max. level = min. measuring distance

If these values are not known, an adjustment with the distances of e.g.

10 % and 90 % is possible. Starting point for these distance specifica tions is always the sealing surface of the thread or flange. You can find further specifications on the reference plane in the chapters " Mounting instructions " and " Technical data ". The actual level is calculated on the basis of these settings.

The actual 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] .

36

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 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.

Setup - Damping

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]

To damp process-dependent measured value fluctuations, set an integration time of 0 … 999 s in this menu item.

Setup - Current output, mode

Depending on the sensor type, the factory setting is 0 s or 1 s.

In the menu item " Current output mode " you determine the output characteristics and reaction of the current output in case of fault.



Setup - Current output

Min./Max.

The default setting is output characteristics 4 … 20 mA, fault mode

< 3.6 mA.

In the menu item " Current output Min./Max.

", you determine the reaction of the current output during operation.

Setup - Lock adjustment

The default setting is min. current 3.8 mA and max. current 20.5 mA.

In this menu item, the PIN is activated/deactivated permanently.

Entering a 4-digit PIN protects the sensor data against unauthorized access and unintentional modifications. If the PIN is activated perma nently, it can be deactivated temporarily (i.e. for approx. 60 min.) in any menu item.

Display - Language

Only the following functions are permitted with activated PIN:

•

Select menu items and show data

Read data from the sensor into the display and adjustment module

Caution:

When the PIN is active, adjustment via PACTware/DTM as well as other systems is also blocked.

In delivery status, the PIN is " 0000 ".

This menu item enables the setting of the requested national language.


Display - Indicated value


In delivery status, the sensor is set to the ordered national language.

In this menu item you can define the indication of the measured value on the display.

Display - Backlight

The default setting for the indicated value is e.g. "Distance" on radar sensors.

The optionally integrated background lighting can be switched on via the adjustment menu. This function depends on the level of the supply voltage, see operating instructions of the respective sensor.

Diagnostics - Device status

In delivery status, the lighting is switched on.

In this menu item, the device status is displayed.

Diagnostics - Peak values

(distance)

The respective min. and max. measured distance values are saved in the sensor. The values are displayed in the menu item " Peak values ".

Diagnosis - Electronics temperature

The respective min. and max. measured values of the electronics temperature are saved in the sensor. These values as well as the current temperature value 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 a dB value. Measurement reliability equals signal strength minus noise. The higher the value, the more reliable the measurement. A well functioning measurement normally has a value > 10 dB.

Diagnosis - Simulation In this menu item you can simulate measured values via the current output. This allows the signal path to be tested, e.g. through downstream indicating instruments or the input card of the control system.

How to start the simulation:

2. Select the requested simulation variable with [->] and confirm with [OK] .

3. With you start the simulation, first of all the actual measured value is displayed in %

4. Start the editing mode with [OK]

5. Set the requested numerical value with [+] and [->] .

Note:

During simulation, the simulated value is output as 4 … 20 mA current value and digital HART signal.

How to interrupt the simulation:

→

Push [ESC]

Information:

The simulation is automatically terminated 10 minutes after the last pressing of a key.

Diagnosis - 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 entire measuring range.

A comparison of echo curve and false signal suppression allows a more detailed statement about measurement 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

The function " Echo curve memory " makes it possible to save the echo curve at the time of setup. This is generally recommended, and it is absolutely necessary if you want to use the Asset Management functions. If possible, the curve should be saved with a low level in the vessel.

With the adjustment software PACTware and a PC, a high resolution echo curve can be displayed and used to recognize signal changes during operation. In addition, the echo curve of setup can be displayed in the echo curve window and compared with the current echo curve.

Additional adjustments -

Instrument units

In this menu item you select the measured variable of the system and the temperature unit.

Additional settings - False signal suppression

The following circumstances cause interfering reflections and can influence the measurement:

• High mounting sockets

Vessel internals such as struts

• Agitators

Buildup or welded joints on vessel walls



Note:

A false signal suppression detects, marks and saves these false signals to ensure that they are ignored in the level measurement.

This should be done with the lowest possible 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 3-times with [OK] and enter the actual distance from the sensor to the product surface.

3. All interfering signals in this range are detected by the sensor and stored after being confirmed 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 ":

Additional settings - Linearization

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 too high a 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 linearization is necessary for all vessels in which the vessel volume does not increase linearly with the level - e.g. a horizontal cylindri -


6 Set up with the display and adjustment module cal 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 ".

Additional settings - PIN

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 setting the switching point on the limit signal transmitter.

Entering a 4-digit PIN protects the sensor data against unauthorized access and unintentional modification. In this menu item, the PIN is displayed or edited and changed. However, this menu item is only available if adjustment is enabled in the menu " Setup ".

In delivery status, the PIN is " 0000 ".

Additional settings - Date/

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. 29: 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 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 parameterisation data

We recommend documenting or saving the parameterisation data via

PACTware. That way the data are available for multiple use or service purposes.


8 Set up with other systems

8 Set up with other systems

8.1 DD adjustment programs

Device descriptions as Enhanced Device Description (EDD) are available for DD adjustment programs such as, for example, AMS™ and PDM.

The files can be downloaded at www.vega.com/downloads under

" Software ".

8.2 Field Communicator 375, 475

Device descriptions for the instrument are available as EDD for parameterisation with Field Communicator 375 or 475.

Integrating the EDD into the Field Communicator 375 or 475 requires the "Easy Upgrade Utility" software, which is available from the manufacturer. This software is updated via the Internet and new EDDs are automatically accepted into the device catalogue of this software after they are released by the manufacturer. They can then be transferred to a Field Communicator.

Cleaning

9 Diagnosis, asset management and service

9.1 Maintenance

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

The cleaning helps that the type label and markings on the instrument are visible.

Take note of the following:

• Use only cleaning agents which do not corrode the housings, type

• label and seals

Use only cleaning methods corresponding to the housing protection rating

Measured value memory

Event memory

Echo curve memory

9.2 Measured value and event memory

The instrument has several memories available for diagnostic purposes. The data remain there even in case of 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

• Measurement 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:


Status messages


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

Further echo curves: Up to 10 echo curves can be stored in a ring buffer in this memory section. Additional echo curves are stored via:

• PC with PACTware/DTM

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, detailed error messages are available under 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

Fig. 30: Pictographs of the status messages

1 Failure - red

2 Out of specification - yellow

3 Function check - orange

4 Maintenance - blue

3 4

Failure: Due to a malfunction in the instrument, a fault message is output.

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

Function check: The instrument is being worked on, 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 unreliable because an instrument specification was 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).

Procedure for fault rectification

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 via the adjustment device

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.

Check the 4 … 20 mA signal

Error

4 … 20 mA signal not stable

4 … 20 mA signal missing

Current signal greater than

22 mA, less than 3.6 mA

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 eliminate them:

Cause

• Fluctuating measured value

•

Electrical connection faulty

•

Voltage supply missing

•

Operating voltage too low, load resistance too high

•

Sensor electronics defective

Rectification

• Set damping

•

Check connection, correct, if necessary

•

Check cables for breaks; repair if necessary

•

Check, adapt if necessary

•

Exchange the instrument or send it in for repair


Treatment of measurement errors with liquids


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 as a broken line and the level displayed by the sensor as a continuous line.

1

2

0

1 Real level

2 Level displayed by the sensor 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

0 time

2. Measured value jumps towards 0 %

Cause

•

Min./max. adjustment not correct

• Incorrect linearisation curve

•

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

•

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

Rectification

•

Adapt min./max. adjustment

• Adapt linearisation curve

•

Check parameter "Application" with respect to vessel form, adapt if necessary

(bypass, standpipe, diameter)

•

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

0

0 time

3. Measured value jumps towards

100 % 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

•

Carry out a false signal suppression

• 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

0 time

5. Measured value remains in the bottom section during filling

Cause

•

False signals in the close range too big or

• level echo too small

Strong foam or spout generation

Max. adjustment not correct

•

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

0 time

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

•

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

0 time

8. Measured value jumps towards

100 % during filling

•

•

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)

•

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

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

•

In case of interferences due to installations in the close range: Change polarisation direction

•

Chose a more suitable installation position

•

Carry out a false signal suppression

0 time

9. Measured value jumps sporadically to

100 % during filling

•

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




10. Measured value jumps to ≥ 100 % or

0 m distance

Cause

•

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 output.

Rectification

•

Check measuring site: Antenna must

• protrude out of the socket


Use a sensor with a more suitable antenna

0 time

Measurement error during emptying


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

0 time

12. Measured value jumps towards 0 % during emptying

Cause

•

False signal larger than the level echo

Level echo too small

•

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

•


In case of interferences due to installa-

• tions in the close range: Change polarisation direction

After eliminating the false signals, the false signal suppression must be deleted.

Carry out a new false signal suppression

•

Check parameters Medium type, Vessel height and Floor form, adapt if necessary

0 time

13. Measured value jumps sporadically towards 100 % during emptying

•

Varying condensation or contamination on the antenna

•

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

0 time

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, the order data must first be downloaded from the Internet (see operating instructions " Electronics module ").

Caution:

All application-specific settings must be entered again. That's why you have to carry out a fresh setup after exchanging the electronics.

If you saved the parameter settings during the first setup of the sen sor, you can transfer them to the replacement electronics module. A fresh setup is then not necessary.
