Product descriptionTypical applications are overfill and dry run protection. Thanksto its simple and robust measuring system, VEGAVIB 63 isvirtually unaffected by the chemical and physical properties ofthe solid.It functions even when exposed to strong external vibration orchanging products.Solid detection in waterIf VEGAVIB 63 was ordered for solid detection in water, thevibrating rod is to the density of water. In air or if covered bywater (density: 1 g/cm³/0.036 lbs/in) VEGAVIB 63 signalsuncovered. Only if the vibrating element is also covered withsolids (e.g. sand, sludge, gravel etc.) will the sensor signalcovered.Fault monitoringThe electronics of VEGAVIB 63 continuously monitors thefollowing criteria:l Correct vibrating frequencyl Line break to the piezo driveIf one of these faults is detected or in case the power supplyfails, the electronics takes on a defined switching condition, i.e.the relay deenergizes (safe condition).Physical principlePower supplyThe vibrating rod is piezoelectrically energised and vibrates atits mechanical resonance frequency of approx. 360 Hz. Whenthe vibrating rod is submerged in the product, the vibratingamplitude changes. This change is detected by the integratedoscillator and converted into a switching command.VEGAVIB 63 is a compact instrument, i.e. it can be operatedwithout external evaluation system. The integrated electronicsevaluates the level signal and outputs a switching signal. Withthis switching signal, a connected device can be operateddirectly (e.g. a warning system, a PLC, a pump etc.).The exact range of the power supply is stated in the Technicaldata in the Supplement.3.3 AdjustmentWith the factory setting with a density >0.05 g/cm³ (>0.002 lbs/in³) can be measured. The instrument can be adapted ifproducts with lower density should be measured.On the electronics module you will find the following indicatingand adjustment elements:8 VEGAVIB 63 - with relay output29277-EN-050812

Mounting4 Mounting4.1 General instructionsSwitching pointMoistureIn general, VEGAVIB 63 can be mounted in any position. Theinstrument must be mounted in such a way that the tuning forkis at the height of the requested switching point.Use the recommended cable (see chapter "Connecting topower supply") and tighten the cable entry.You can give your VEGAVIB 63 additional protection againstmoisture penetration by leading the connection cable downwardin front of the cable entry. Rain and condensation watercan thus drain off. This applies mainly to mounting outdoors, inareas where moisture is expected (e.g. by cleaning processes)or on cooled or heated vessels.Fig. 2: Measures against moisture penetrationTransportPressure/VacuumDo not hold VEGAVIB 63 on the vibrating element. Especiallywith flange and tube versions, the sensor can be damaged bythe weight of the instrument.Remove the protective cover just before mounting.The process fitting must be sealed if there is gauge or lowpressure in the vessel. Before use, check if the seal material isresistant against the measured product and the processtemperature.HandlingThe vibrating level switch is a measuring instrument and mustbe treated accordingly. Bending the vibrating element willdestroy the instrument.10 VEGAVIB 63 - with relay output29277-EN-050812

MountingWarning:The housing must not be used to screw the instrument in!Applying tightening force to the housing can damage itsinternal mechanical components.To screw in, use the hexagon above the thread.4.2 Mounting informationAgitators and fluidizationDue to agitators, vibrations or similar, the level switch can besubjected to strong lateral forces. For this reason, do not usean overly long extension tube for VEGAVIB 63, but check if youcan mount a short level switch on the side of the vessel inhorizontal position.Extreme vibrations from the system side, e.g. by agitators orturbulence in the vessel, e.g. by fluidization can cause theextension tube of VEGAVIB 63 to vibrate. This will causeincreased stress on the upper weld joint. Should a longer tubeversion be necessary, you can provide a suitable straining orfastening directly above the tuning fork to fasten the extensiontube.This measure applies particularly to applications in Ex areas.Make sure that the tube is not subjected to bending forcesthrough this measure.Inflowing materialIf VEGAVIB 63 is mounted in the filling stream, unwantedswitching signals may be generated. Mount VEGAVIB 63 at alocation in the vessel where no disturbing influence from e.g.filling openings, agitators, etc. can occur.This applies particularly to instrument types with longextension tube.29277-EN-050812VEGAVIB 63 - with relay output 11

MountingFig. 3: Inflowing materialLock fittingSocketMaterial coneVEGAVIB 63 can be mounted with a lock fitting for heightadjustment. Take note of the pressure information of the lockfitting.The vibrating element should protrude into the vessel to avoidbuildup. For that reason, avoid using mounting bosses forflanges and screwed fittings. This applies particularly to usewith adhesive products.Material cones can form in solids silos which can change theswitching point. Please keep this in mind when installing thesensor in the vessel. We recommend selecting an installationlocation where the vibrating rod detects an average value ofthe material cone.Depending on the arrangement of the filling and emptyingopening in the vessel, the vibrating rod must be mountedrespectively.To compensate measurement errors in cylindrical vesselscaused by the material cone, the sensor must be mounted at adistance of d/6 from the vessel wall.12 VEGAVIB 63 - with relay output29277-EN-050812

Tomaintain this protection class, it is absolutely necessary thatthe ground conductor is connected to the internal groundterminal. Take note of the general installation regulations. As arule, connect VEGAVIB 63 to vessel ground (PA), or in case ofplastic vessels, to the next ground potential. On the side of thehousing there is a ground terminal between the cable entries.This connection serves to drain off electrostatic charges. In Exapplications, the installation regulations for hazardous areasmust be given priority.The data for power supply are stated in the Technical data inthe Supplement.VEGAVIB 63 is connected with standard cable with round wirecross section. An outer cable diameter of 5 … 9 mm(0.2 … 0.35 in) ensures the seal effect of the cable entry.If cable with a different diameter or wire cross section is used,exchange the seal or use an appropriate cable connection.In hazardous areas, only use approved cable connections forVEGAVIB 63.Select connectioncable for Ex applicationsTake note of the corresponding installation regulations for Exapplications.5.2 Connection procedureWith Ex instruments, the housing cover may only be opened ifthere is no explosive atmosphere.Proceed as follows:16 VEGAVIB 63 - with relay output29277-EN-050812

The switching output willchange if you set the mode switch (2) afterwards. This couldpossibly trigger other connected instruments or devices.6.2 Adjustment elements51243Fig. 11: Electronics module VB 60R - Relay output1 Potentiometer for switching point adaptation2 DIL switch for mode adjustment3 Ground terminal4 Terminals5 Control lamp20 VEGAVIB 63 - with relay output29277-EN-050812

Set upSwitching point adaptation (1)Mode adjustment (2)Signal lamp (5)You can adapt the switching point to the solid with thepotentiometer. The switching point is preset and covered by alabel. It must only be modified in special cases.By default, the potentiometer of VEGAVIB 63 is set to midposition (0.05 … 1 g/cm³ or 0.002 … 0.036 lbs/in³). In very lightsolids, turn the potentiometer to complete left position(0.02 … 0.1 g/cm³ or 0.0007 … 0.0036 lbs/in³). By doing this,VEGAVIB 63 will be more sensitive and light solids can bedetected more reliably.For very heavy solids, turn the potentiometer to the completeright position (>0.3 g/cm³ or >0.011 lbs/in³). Hence VEGAVIB63 is less sensitive.For instruments detecting solids in water, these values are notapplicable. The potentiometer is preset and must not bechanged.With the mode adjustment (min./max.) you can change theswitching condition of the relay. You can set the required modeacc. to the "Function chart" (max. -max. detection or overfillprotection, min. -min. detection or dry run protection).We recommend connecting acc. to the quiescent currentprinciple (replay contact deenergizes when reaching theswitching point), because the relay takes on the same (safe)condition if a failure is detected.Signal lamp for indication of the switching condition.lllgreen = relay energizedred = relay deenergizedred (flashing) = failure6.3 Function chartThe following chart provides an overview of the switchingconditions depending on the adjusted mode and level.max. modeOverfill protectionLevelSwitching statusControl lamp29277-EN-0508123 4 5(6) (7) (8)Relay energized greenVEGAVIB 63 - with relay output 21

Functional safety9 Functional safety9.1 GeneralValidityArea of applicationSafety functionRelevant standardsSafety requirementsThis safety manual applies to measuring systems consisting ofVEGAVIB 63 vibrating level switches and integrated oscillatorVB60R. The instrument corresponds to a subsystem of type B.The sensor software must correspond at least to version 1.03or higher.The measuring system can be used for level detection ofpowders and granules which meet the specific requirements ofthe safety technology, e.g.:l Mode "max" for overfill protectionl Mode "min" for dry run protectionThe measuring system is qualified in both modes to meet thefollowing requirement degree acc. to IEC 61508-2:l SIL2 with architecture 1oo1D (single channel)l SIL3 with architecture 1oo2D (double-channel/redundant)With a special factory setting, the measuring system is alsosuitable for detection of solids in water (see operatinginstructions manual).The safety function of this measuring system is the detectionand signalling of the condition of the vibration element.

Functional safetyLow demand modeHigh demand model The communication via the IIC bus interface is only usedfor default scaling and for service purposes.l The repair time (exchange of the meas. system) after a failsafeerror is eight hours (MTTR = 8 h)l In the mode with the lowest demand rate, the reaction timeof a connected control and processing unit to dangerousdetectable errors is max. 1 hour.If the demand rate is only once a year, then the measuringsystem can be used as safety-relevant subsystem in "lowdemand mode" (IEC 61508-4, 3.5.12).If the ratio of the internal diagnostics test rate of the measuringsystem to the demand rate exceeds the value 100, themeasuring system can be treated in the way it is executing asafety function in the mode with low demand rate (IEC 61508-2,7.4.3.2.5).Corresponding characteristics is the value PFD avg (averageProbability of dangerous Failure on Demand). It is dependenton the test interval T Proof between the function tests of theprotective function.Numbers see paragraph "Safety-technical characteristics".If the "low demand mode" does not apply, the measuringsystem must be used as safety-relevant subsystem in "highdemand" (IEC 61508-4, 3.5.12).The fault tolerance time of the complete system must be higherthan the sum of the reaction times or the diagnostics testperiods of all components in the safety chain.Corresponding characteristics is the value PFH (failure rate).Numbers see paragraph "Safety-technical characteristics".Safe condition and fault descriptionThe safe condition of the measuring system is the switched offstatus (quiescent current principle):l VB60R (relay output) –Relay deenergizedA fail-safe failure (safe failure) exists if the measuring systemchanges to the defined safe condition without demand of theprocess.If the internal diagnosis system recognises a failure, the safecondition is taken up.A dangerous undetected failure exists if the measuring systemdoes not go to the defined safe condition when required by theprocess.30 VEGAVIB 63 - with relay output29277-EN-050812

Functional safetyConfiguration of the processingunitThe processing unit must evaluate the output circuit of themeasuring system by taking the quiescent current principleinto account.The processing unit must correspond to the SIL level of themeasuring chain.9.3 SetupMounting and installationThe prevailing plant conditions influence the safety of themeasuring system. Therefore note the mounting and installationinstructions of the appropriate operating instructionsmanual. Mainly important is the correct setting of the mode(min./max.).In heavy or very light-weight solids the switching point of themeasuring system must be adapted acc. to the operatinginstructions manual depending on the density limits.9.4 Reaction during operation and in case offailurellllllThe adjustment elements must not be modified duringoperation.In case of modifications during operation, you have to takenote of the safety functions.Occurring fault signals are described in the appropriateoperating instructions manual.In case of detected failures or fault signals, the entiremeasuring system must be switched out of service and theprocess held in a safe condition by means of othermeasures.An electronics exchange is easily possible and describedin the operating instructions manual.If due to the detected failure, the electronics or thecomplete sensor is interchanged, the manufacturer mustbe informed (incl. a fault description).29277-EN-0508129.5 Recurring function testThe recurring function test serves to reveal potential dangerouserrors that are otherwise not discernible. The function ofthe measuring system must be checked at adequate intervals.The operator is responsible for choosing the type of test andthe intervals in the stated time frame. The time frame dependson the PFD avg value acc. to the chart and diagram in section"Safety-related characteristics".VEGAVIB 63 - with relay output 31

Functional safetyIn high demand rate, no recurring function test is arranged inIEC 61508. A proof of the functional efficiency is seen in themore frequent demand of the measuring system. In doublechannel architectures it is useful to proof the redundancy byrecurring function tests in appropriate intervals.The test must be carried out in a way that verifies the flawlessoperation of the safety functions in conjunction with all systemcomponents.This is ensured by a controlled reaching of the response heightduring filling. If filling up to the response height is not possible,then a response of the measuring system must be triggered bya suitable simulation of the level or the physical effect.The methods and procedures used during the tests must bestated and their suitability must be specified. The tests must bedocumented.If the function test proves negative, the entire measuringsystem must be switched out of service and the process heldin a safe condition by means of other measures.In the double channel architecture 1oo2D this appliesseparately to both channels.9.6 Safety-related characteristicsThe failure rates of the electronics and the vibrating system aredetermined by an FMEDA acc. to IEC 61508. Thesecalculations are based on component failure rates acc. toSN 29500. All numerical values refer to an average ambienttemperature during the operating time of +40°C (104°F). Thecalculations are also based on the specifications stated inchapter "Planning".Overfill protectionMode switch is set to "max"λ sd 0 FIT safe detected failure (1 FIT = failure/10 9 h)λ su 586 FIT safe undetected failureλ dd 124 FIT dangerous detected failureλ du 27 FIT dangerous undetected failureSFF >96 % Safe Failure FractionDC S 0 % Diagnosis coverage DC S = λ sd /(λ sd + λ su )DC D 82 % Diagnosis coverage DC D = λ dd /(λ dd + λ du )32 VEGAVIB 63 - with relay output29277-EN-050812
