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 ttings and under simple process conditions.
The instrument can be used with products with an ε actually achievable value depends on the measuring conditions, the antenna system, the standpipe or bypass.
The antenna of the radar sensor emits short radar pulses with a duration of approx. 1 ns. These pulses are reected by the product and received by the antenna as echoes. The transit time of the radar pulses from emission to reception is proportional to the distance and hence to the level. The determined level is converted into an appropri­ate output signal and outputted as measured value.
The instrument is powered via an integrated accumulator. This allows operation of the instrument independently of the mains or a control system. To achieve a longer battery lifetime, the instrument is preset to HART multidrop. This puts a load of only 4 mA current on the ac­cumulator.

4.1 General instructions

With instruments with threaded process tting, suitable tools must be applied for tightening the hexagon.
Warning:
The housing must not be used to screw the instrument in! Applying tightening force can damage internal parts of the housing.
Moisture
Suitability for the process conditions
Sealing of the encapsu­lated antenna system
Use the recommended cables (see chapter "Connecting to power supply") and tighten the cable gland.
You can give your instrument additional protection against moisture penetration by leading the connection cable downward in front of the cable entry. Rain and condensation water can thus drain o. This ap­plies mainly to outdoor mounting as well as installation in areas where high humidity is expected (e.g. through cleaning processes) or on cooled or heated vessels.
Make sure that all parts of the instrument exposed to the process, in particular the active measuring component, process seal and process tting, are suitable for the existing process conditions. These include above all the process pressure, process temperature as well as the chemical properties of the medium.
You can nd the specications in chapter "Technical data" and on the type label.

4.2 Instructions for installation

The ange screws must be tightened so that the PTFE washer of the encapsulated antenna system seals eectively. You can nd the required torque in the technical data.
You can counteract the material-induced tension loss with PTFE by doing the following:
1. Make sure the number of ange screws corresponds to the num­ber of ange holes
2. Use disc springs in addition to the ange screws for fastening the ange
3. Tighten all screws with the torque stated in the technical data
Polarisation plane
14
The emitted radar impulses of the radar sensor are electromagnetic waves. The polarisation plane is the direction of the electrical wave component. By turning the instrument in the connection ange or mounting boss, the polarisation can be used to reduce the eects of false echoes.
The position of the polarisation plane is marked on the process tting of the instrument.

Installation position
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 keep this distance you should carry out a false echo storage before setup. This applies mainly if buildup on the vessel wall is expected. In this case, we recommend repeating a false echo stor­age later with existing buildup.

(19.69
Fig. 6: Mounting of the radar sensor on round vessel tops
In vessels with conical bottom it can be advantageous to mount the sensor in the center of the vessel, as measurement is then possible down to the lowest point of the vessel bottom.

Socket
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. 8: Mounting of the radar sensor with inowing medium
The active part of the antenna, i.e. the conical antenna part should protrude completely out of the socket.
To meet the dierent socket dimensions, sensors for socket lengths up to 50, 100 and 250 mm (2, 4, 10 in) are available.

4 Mounting
Fig. 9: 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.
Sensor orientation
Vessel installations
Align the sensor in liquids as vertical as possible to the product sur­face to achieve optimum measurement.
Fig. 10: Alignment in liquids
The mounting location of the radar sensor should be a place where no other equipment or xtures 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 site 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 baes above the installations scatter the radar signals and prevent direct interfering reections.

4 Mounting
Fig. 11: Cover smooth proles with deectors
Agitators
Foam generation
If there are agitators in the vessel, a false signal memory should be carried out with the agitators in motion. This ensures that the interfer­ing reections from the agitators are saved with the blades in dierent positions.
Fig. 12: Agitators
Through the action of lling, stirring and other processes in the vessel, dense foams which considerably damp the emitted signals may form on the product surface.
If foams are causing measurement errors, the biggest possible radar antenna should be used.
As an alternative, sensors with guided microwave can be used. These are unaected by foam generation and are best suited for such ap­plications.

You can nd in the operating instructions manual "Indicating and ad- justment module" also the description of the menu sections "Display" and "Info".
In the main menu point "Setup", the individual submenu points should be selected subsequently and provided with the correct parameters to ensure the optimum adjustment of the measurement. The proce­dure is described in the following.
Setup
Setup/Medium
Each medium has dierent reection properties. With liquids, further interfering factors are uctuation product surface and foam genera­tion. With bulk solids, these are dust generation, material cone and additional echoes from the vessel wall.
To adapt the sensor to these dierent measuring conditions, the selection "Liquid" or "Bulk solid" should be made in this menu item.
24
Through this selection, the sensor is adapted perfectly to the product
40932-EN-121011

6 Set up with the indicating and adjustment module
Setup/Adjustment
Since a radar sensor is a distance measuring instrument, the distance from the sensor to the product surface is measured. For indication of the real level, an allocation of the measured distance to the percent­age height must be carried out.
To perform the adjustment, enter the distance with full and empty ves­sel, see the following example:
")
1 m
(39.37
100%
2
")
10 m
(393.7
0%

Fig. 19: Parameter adjustment example min./max. adjustment
1 Min. level = max. meas. distance 2 Max. level = min. meas. distance
If these values are not known, an adjustment with the distances of for example 10 % and 90 % is possible. Starting point for these distance specications is always the seal surface of the thread or ange. By means of these settings, the real level will be calculated.
The real product level during this adjustment is not important, be­cause the min./max. adjustment is always carried out without chang­ing the product level. These settings can be made ahead of time without the instrument having to be installed.
Setup/Min. adjustment

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

Diagnosis/Peak value
Proceed as follows:
1. Select with [->] the menu item max. adjustment and conrm with [OK].
2. Prepare the percentage value for editing with [OK] and set the cursor to the requested position with [->].
3. Set the requested percentage value with [+] and save with [OK]. The cursor jumps now to the distance value.
4. Enter the appropriate distance value in m (corresponding to the percentage value) for the full vessel. Keep in mind that the max. level must lie below the min. distance to the antenna edge.
5. Save settings with [OK]
The respective min. and max. measured value is saved in the sensor. The values are displayed in the menu item "Peak values".
Diagnosis/Measurement reliability
40932-EN-121011
When non-contact level sensors are used, the measurement can be inuenced by the respective process conditions. In this menu item, the measurement reliability of the level echo is displayed as dB value. The measurement reliability equals signal strength minus noise. The
31
6 Set up with the indicating and adjustment module
higher the value, the more reliable the measurement. With a function­ing measurement, the values are > 10 dB.
Diagnoses/Curve indica­tion
The "Echo curve" shows the signal strength of the echoes over the measuring range in dB. The signal strength enables an evaluation of the quality of the measurement.
The "False signal suppression" displays the saved false echoes (see menu "Additional settings") of the empty vessel with signal strength in "dB" over the measuring range.
A comparison of echo curve and false signal suppression allows a more accurate conclusion on measurement reliability. The selected curve is continuously updated. With the [OK] key, a submenu with zoom functions is opened:
"X-Zoom": Zoom function for the meas. distance
"Y-Zoom": 1, 2, 5 and 10x signal magnication in "dB"
"Unzoom": Reset the presentation to the nominal measuring range
with single magnication
Diagnostics/Echo curve memory
32
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.
40932-EN-121011
6 Set up with the indicating and adjustment module
Additional adjustments/ False signal suppression
The following circumstances cause interfering reections and can inuence the measurement:
High sockets
Vessel installations such as struts
Agitators
Buildup or welded joints on vessel walls
Note:
A false signal suppression detects, marks and saves these false sig­nals so that they are no longer taken into account for level measure­ment.
This should be done with the low level so that all potential interfering reections can be detected.
Proceed as follows:
1. Select the menu item "Additional settins" with [->] and conrm with [OK]. With [->] you have to select the menu item "False signal suppression" and conrm with [OK].
2. Conrm again with [OK].
3. Conrm again with [OK].
4. Conrm again with [OK] and enter the actual distance from the sensor to the product surface.
5. All interfering signals in this section are detected by the sensor and stored after conrming with [OK].
Note:
Check the distance to the product surface, because if an incorrect (too large) value is entered, the existing level will be saved as false signal. The lling level would then no longer be detectable in this area.
40932-EN-121011
33
6 Set up with the indicating and adjustment module
If a false signal suppression has already been created in the sensor, the following menu window appears when selecting "False signal suppression":
The menu item "Delete" is used to completely delete an already cre­ated false signal suppression. This is useful if the saved false signal suppression no longer matches the metrological conditions in the vessel.
The menu item "Extend" is used to extend an already created false signal suppression. This is useful if a false signal suppression was carried out with a too high level and not all false signals could be de­tected. When selecting "Extend", the distance to the product surface of the created false signal suppression is displayed. This value can now be changed and the false signal suppression can be extended to this range.
Additional adjustments/ Linearization curve
A linearization is necessary for all vessels in which the vessel volume does not increase linearly with the level - e.g. in a horizontal cylindri­cal or spherical tank - and the indication or output of the volume is required. Corresponding linearization curves are preprogrammed for these vessels. They represent the correlation between the level percentage and vessel volume.
By activating the appropriate curve, the volume percentage of the vessel is displayed correctly. If the volume should not be displayed in percent but e.g. in l or kg, a scaling can be also set in the menu item "Display".
Enter the requested parameters via the appropriate keys, save your settings and jump to the next menu item with the [ESC] and [->] key.
Caution:
Note the following if the instrument with corresponding approval is used as part of an overll protection system according to WHG:
If a linearisation curve is selected, the measuring signal is no longer linearly proportional to the level. This must be taken into consideration by the user, particularly when setting the switching point on the level switch.

Additional adjustments
- Reset
When a reset is carried out, all settings (with only a few exceptions) are reset. The exceptions are: PIN, language, lighting, SIL and HART mode.
The following reset functions are available:
Delivery status: Restoring the parameter settings at the time of ship­ment from the factory incl. the order-specic settings. A created false signal suppression, user-programmable linearization curve as well as the measured value memory will be deleted.
Basic settings: Resetting the parameter settings incl. special and laboratory parameters to the default values of the respective instru­ment. A created false signal suppression, user programmable lineari­zation curve as well as the measured value memory will be deleted.
Setup: Resetting of the parameter settings to the default values of the respective instrument in the menu item Setup. User-generated false signal suppression, user-programmed linearization curve, measured value memory as well as event memory remain untouched. The linearization is set to linear.
False signal suppression: Deleting a previously created false signal suppression. The false signal suppression created in the factory remains active.
Peak values distance: Resetting the measured min. and max. dis­tances to the actual measured value.

6.4 Saving the parameter adjustment data

We recommended noting the adjusted data, e.g. in this operating instructions manual, and archiving them afterwards. They are thus available for multiple use or service purposes.
If the instrument is equipped with an indicating and adjustment module, the data in the sensor can be saved in the indicating and adjustment module. The procedure is described in the operating
40932-EN-121011
6 Set up with the indicating and adjustment module
instructions manual "Indicating and adjustment module" in the menu item "Copy sensor data". The data remain there permanently even if the sensor power supply fails.
The following data or settings for adjustment of the indicating and adjustment module are saved:
All data of the menu "Setup" and "Display"
In the menu "Additional adjustments" the items "Sensor-specic
units, temperature unit and linearization" The values of the user programmable linearisation curve
The function can also be used to transfer settings from one instru­ment to another instrument of the same type. If it is necessary to exchange a sensor, the indicating and adjustment module is inserted into the replacement instrument and the data are likewise written into the sensor via the menu item "Copy sensor data".

The interface adapter VEGACONNECT 3 is not suitable for connec­tion to the sensor.

7.2 Parameter adjustment with PACTware

For parameter adjustment of the sensor via a Windows PC, the con­guration software PACTware and a suitable instrument driver (DTM) according to FDT standard are required. The up-to-date PACTware version as well as all available DTMs are compiled in a DTM Collec­tion. The DTMs can also be integrated into other frame applications according to FDT standard.
Note:
To ensure that all instrument functions are supported, you should always use the latest DTM Collection. Furthermore, not all described functions are included in older rmware versions. You can download the latest instrument software from our homepage. A description of the update procedure is also available in the Internet.
Further setup steps are described in the operating instructions manu­al "DTM Collection/PACTware" attached to each DTM Collection and which can also be downloaded from the Internet. Detailed descrip­tions are available in the online help of PACTware and the DTMs.

9.1 Maintenance

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

9.2 Measured value and event memory

The instrument has several memories which are available for diagno­sis purposes. The data remain even with voltage interruption.
Measured value memory
Event memory
Echo curve memory
Up to 60,000 measured values can be stored in the sensor in a ring memory. Each entry contains date/time as well as the respective measured value. Storable values are for example:
Distance
Filling height
Percentage value
Lin. percent
Scaled
Current value
Meas. reliability
Electronics temperature
When the instrument is shipped, the measured value memory is active and stores distance, measurement certainty and electronics temperature every 3 minutes.
The requested values and recording conditions are set via a PC with PACTware/DTM or the control system with EDD. Data are thus read out and also reset.
Up to 500 events are automatically stored with a time stamp in the sensor (non-deletable). Each entry contains date/time, event type, event description and value. Event types are for example:
Modication of a parameter
Switching on and o times
Status messages (according to NE 107)
Error messages (according to NE 107)
The data are read out via a PC with PACTware/DTM or the control system with EDD.
The echo curves are stored with date and time and the corresponding echo data. The memory is divided into two sections:
Echo curve of the setup: This is used as reference echo curve for the measurement conditions during setup. Changes in the measure­ment conditions during operation or buildup on the sensor can thus be recognized. The echo curve of the setup is stored via:
PC with PACTware/DTM
Control system with EDD

Out of specication
Maintenance requirement
and explained by pictographs:
41 2 3
Fig. 22: Pictograms of the status messages
1 Failure - red
2 Function check - orange
3 Out of specication - yellow 4 Maintenance - blue
Failure: Due to a malfunction in the instrument, a failure message is outputted.
This status message is always active. It cannot be deactivated by the user.
Function check: The instrument is in operation, the measured value is temporarily invalid (for example during simulation).
This status message is inactive by default. It can be activated by the user via PACTware/DTM or EDD.
Outofspecication: The measured value is unstable because the instrument specication is exceeded (e.g. electronics temperature).
This status message is inactive by default. It can be activated by the user via PACTware/DTM or EDD.
Maintenance: Due to external inuences, the instrument function is limited. The measurement is aected, but the measured value is still valid. Plan in maintenance for the instrument because a failure is expected in the near future (e.g. due to buildup).
This status message is inactive by default. It can be activated by the user via PACTware/DTM or EDD.

9.5 Exchanging the electronics module

If the electronics module is defective, it can be replaced by the user.
In Ex applications only one instrument and one electronics module 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").

9.6 Software update

The following components are required to update the sensor soft­ware:
Sensor
Voltage supply
Interface adapter VEGACONNECT 4
PC with PACTware

10 Dismounting

10 Dismounting

10.1 Dismounting steps

Warning:
Before dismounting, be aware of dangerous process conditions such as e.g. pressure in the vessel, high temperatures, corrosive or toxic products etc.
Take note of chapters "Mounting" and "Connecting to power supply" and carry out the listed steps in reverse order.

10.2 Disposal

The instrument consists of materials which can be recycled by spe­cialised recycling companies. We use recyclable materials and have designed the parts to be easily separable.
Materials: see chapter "Technical data"
For disposal or recycling within the European Union proceed accord­ing to the "Electronics recycling" and "Battery/Accumulator recycling" below. Outside the European Union you should take note of the valid national regulations.
Electronics recycling
This instrument is not subject to the WEEE directive 2002/96/EG and the respective national laws. Therefore pass the instrument directly on to a specialised recycling company and do not use the municipal collecting points. These may be used only for privately used products according to the WEEE directive.
Battery/accumulator recycling
Note:
The disposal is subject to the directive 2006/66/EG on batteries and accumulators.
Batteries and accumulators contain some environmentally harm­ful but also some valuable raw materials that can be recycled. For that reason batteries and accumulators must not be disposed of in household waste.
All users are legally obligated to bring batteries to a suitable collection point, e.g. public collection points. You can also return the batteries and accumulators to us for correct disposal. Due to the very strict transport regulations for lithium-based batteries/accumulators, this is normally not a good idea because shipment is very expensive.
Proceed as follows to dismount the accumulator:
Unscrew the cover of the supply room
Loosen the plug connector
Loosen the xing screws
Pull out the complete insert by means of the plastic strap
Correct disposal avoids negative eects on humans and the environ­ment and ensures recycling of useful raw materials.
