3.2 Principle of operationThe VEGAPULS 68 is a radar sensor for continuous measurement of bulk solids also under arduous process conditions and large measur-ing ranges. It the ideal solution for level measurement in high silos, largebunkers,stonecrushersandmeltingfurnaces.Withdifferentantenna versions and materials, this sensor is the optimum solution for virtually all applications and processes.The instrument is also suitable for applications in liquids.Dependentontheapplicationrange,differentversionsareused:

• Small silos and vessels, measurement of virtually all bulk solids: Horn antenna

• Largesilosandvessels,measurementofbulksolidswithlowεr value: Parabolic antenna

• Liquids: Parabolic antenna

Theinstrumentcanbeusedwithproductswithanεrvalue≥1.5.Theactually achievable value depends on the measuring conditions and the antenna system.

The antenna of the radar sensor emits short radar pulses with a durationofapprox.1ns.Thesepulsesarereflectedbytheproductand received by the antenna as echoes. The transit time of the radar

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

Protect your instrument against moisture ingress through the following measures:

• Use the recommended cable (see chapter "Connecting to power supply")

• Tighten the cable gland• Whenmountinghorizontally,turnthehousingsothatthecable

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

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• Processfitting• Process seal

Process conditions are particularly:

• Process pressure• Process temperature• Chemical properties of the medium• AbrasionandmechanicalinfluencesYoucanfinddetailedinformationontheprocessconditionsinchapter"Technicaldata" as well as on the type label.

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 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 ap-proved cable glands or close the openings with suitable blind plugs.

Information:The hexagon screws must not be loosened.

The mounting location of the radar sensor should be a place where no otherequipmentorfixturescrossthepathoftheradarsignals.Vessel installations, such as e.g. ladders, limit switches, heating spi-rals, 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.

Large material heaps are detected with several sensors, which can be mounted on e.g. traverse cranes. For this type of application, it is best to orient the sensor toward the solid surface. A mutual infuence of the sensors is not possible.

Fig. 18: Radar sensors on traverse crane

Information:Keep in mind that for these applications, the sensors are designed for relatively slow level changes. When using VEGAPULS 68 on a mov-able bracket, the max. measuring rate must be observed (see chapter "Technicaldata").

Instruments for a temperature range up to 250 °C or up to 450 °C haveadistancepiecebetweenprocessfittingandelectronicshous-ing. Ths distance piece is used for thermal decoupling of the electron-ics against high process temperatures.

To avoid strong buildup and dust in the antenna system, the sensor should not be mounted directly at the dust extraction of the vessel.In case of extreme dust deposits in the antenna system, VEGAPULS 68 is available with a rinsing air connection. The air is distributed via channels in the antenna system and keeps it largely free of dust.

5.1 Preparing the connectionAlways 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.

Power supply and current signal are carried on the same two-wire cable.Theoperatingvoltagecandifferdependingontheinstrumentversion.Thedataforpowersupplyarespecifiedinchapter"Technicaldata".Provide a reliable separation between the supply circuit and the mains circuits according to DIN EN 61140 VDE 0140-1.Keepinmindthefollowingadditionalfactorsthatinfluencetheoperat-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)

• Influenceofadditionalinstrumentsinthecircuit(seeloadvaluesinchapter "Technicaldata")

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 cablegland.Toensurethesealeffectofthecablegland(IPprotectionrating),findoutwhichcableouterdiameterthecableglandissuitablefor.Useacableglandfittingthecablediameter.We generally recommend the use of screened cable for HART multi-drop mode.

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 "Technicaldata".

If screened cable is required, we recommend connecting the cable screen on both ends to ground potential. In the sensor, the screen must be connected directly to the internal ground terminal. The ground terminal on the outside of the housing must be connected to the ground potential (low impedance).In Ex systems, the grounding is carried out according to the installa-tion regulations.

In electroplating and CCP systems (cathodic corrosion protection) it mustbetakenintoaccountthatsignificantpotentialdifferencesexist.This can lead to unacceptably high currents in the cable screen if it is grounded at both ends.

Information:Themetallicpartsoftheinstrument(processfitting,transmitter,concentric tube, etc.) are connected with the inner and outer ground terminal on the housing. This connection exists either directly via con-necting metallic parts or, in case of instruments with external electron-ics, via the screen of the special connection cable.Youcanfindspecificationsonthepotentialconnectionsinsidetheinstrument in chapter "Technicaldata".

5.2 ConnectingThe voltage supply and signal output are connected via the spring-loaded 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 lid2. If a display and adjustment module is installed, remove it by turn-

ing it slightly to the left.3. Loosen compression nut of the cable entry gland4. 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 wires5. Insert the cable into the sensor through the cable entry

9.1 MaintenanceIf the device is used correctly, no maintenance is required in normal operation.Insomeapplications,buildupontheantennasystemcaninfluencethe measuring result. Depending on the sensor and application, make arrangements to avoid strong pollution of the antenna system. If nec-essary, clean the antenna system in certain intervals.

9.2 Measured value and event memoryThe instrument has several memories which are available for diagno-sis 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 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:

• Modificationofaparameter• Switch-onandswitch-offtimes• 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 measure-ment conditions during operation or buildup on the sensor can thus berecognized.Theechocurveofthesetupisstoredvia:

9.4 Rectify faultsThe operator of the system is responsible for taking suitable meas-ures to rectify faults.

Thefirstmeasuresare:

• 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 bedeterminedinthiswayandfaultsrectified.

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:

Error Cause Rectification

4 … 20 mA signal not stable

– Fluctuations of the measured variable

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

4 … 20 mA signal missing

– Electrical con-nection faulty

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

– Voltage supply missing

– Check cables for breaks; repair if necessary

– Operating volt-age too low or load resistance too high

– Check, adapt if necessary

Current sig-nal greater than 22 mA or less than 3.6 mA

– Electronics module in the sensor defec-tive

– Exchange the instrument or send it in for repair

The below tables show typical examples of application-related measurement errors with bulk solids. A distinction is made between measurement errors during:

– Various echoes from an uneven product surface, e.g. an extrac-tion funnel

– Check parameter "Type of medium" and adapt, if neces-sary

– Optimizeinstallationpositionand sensor orientation

– Reflectionsfromtheproductsurface via the vessel wall (deflection)

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

9.5 Exchanging the electronics moduleIf the electronics module is defective, it can be replaced by the user.In Ex applications, only instruments and electronics modules with ap-propriate 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 electron-icsmodulesareadaptedtotherespectivesensoranddifferinsignaloutput 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.Whenloadingonsite,firstofalltheorderdatamustbedownloadedfrom the Internet (see operating instructions manual "Electronicsmodule").

Caution:Alluser-specificsettingsmustbeenteredagain.Hence,youhavetocarry out a new setup after the electronics exchange.
