Product descriptionIt is designed for industrial use in all areas of processtechnology and is preferably used for bulk solids.Typical applications are overfill and dry run protection. Thanksto its simple and robust measuring system, OPTISWITCH3300 C is virtually unaffected by the chemical and physicalproperties of the solid.It functions even when exposed to strong external vibration orchanging products.Solid detection in waterIf OPTISWITCH 3300 C was ordered for solid detection inwater, the tuning fork is set to the density of water. In air orwhen immersed in water (density: 1 g/cm³ / 0.036 lbs/in),OPTISWITCH 3300 C signals "uncovered". Only when thevibrating element is also covered with solids (e.g. sand,sludge, gravel etc.) will the sensor signal "covered".Fault monitoringThe electronics of OPTISWITCH 3300 C continuously monitorsthe following 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 contactless electronic switch opens (safe condition).Physical principlePower supplyThe tuning fork is piezoelectrically energised and vibrates at itsmechanical resonance frequency of approx. 150 Hz. When thetuning fork is submerged in the product, the vibrationamplitude changes. This change is detected by the integratedoscillator and converted into a switching command.OPTISWITCH 3300 C is a compact instrument, i.e. it can beoperated without external evaluation system. The integratedelectronics evaluates the level signal and outputs a switchingsignal. With this switching signal, a connected device can beoperated directly (e.g. a warning system, a PLC, a pump etc.).The exact range of the voltage supply is specified in the"Technical data" in the "Supplement".8 OPTISWITCH 3300 C - with contactless electronic switch29960-EN-060112

Product description3.3 AdjustmentWith the factory setting, products with a density of >0.02 g/cm³(>0.0008 lbs/in³) can be measured. It is possible to adapt theinstrument for products with lower density >0.008 g/cm³(>0.0003 lbs/in³).On the electronics module you will find the following indicatingand adjustment elements:lllsignal lamp for indication of the switching condition (green/red)potentiometer for adaptation to the product densitymode switch for selection of the output current3.4 Storage and transportPackagingStorage and transport temperatureYour instrument was protected by packaging during transport.Its capacity to handle normal loads during transport is assuredby a test acc. to DIN 55439.The packaging of standard instruments consists of environment-friendly,recyclable cardboard. In addition, the sensor isprovided with a protective cover of cardboard. For specialversions PE foam or PE foil is also used. Dispose of thepackaging material via specialised recycling companies.l Storage and transport temperature see "Supplement -Technical data - Ambient conditions"l Relative humidity 20 … 85 %29960-EN-060112OPTISWITCH 3300 C - with contactless electronic switch 9

Mounting4 Mounting4.1 General instructionsSwitching pointMoistureIn general, OPTISWITCH 3300 C can be mounted in anyposition. The instrument must be mounted in such a way thatthe vibrating element is at the height of the requested switchingpoint.Use the recommended cable (see chapter "Connecting topower supply") and tighten the cable gland.You can give your OPTISWITCH 3300 C additional protectionagainst moisture penetration by leading the connection cabledownward in front of the cable entry. Rain and condensationwater can thus drain off. This applies mainly to mountingoutdoors, in areas where moisture is expected (e.g. bycleaning processes) or on cooled or heated vessels.Fig. 2: Measures against moisture penetrationTransportDo not hold OPTISWITCH 3300 C on the vibrating element.Especially with flange and tube versions, the sensor can bedamaged by the weight of the instrument.Remove the protective cover just before mounting.Pressure/VacuumHandlingThe 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.The vibrating level switch is a measuring instrument and mustbe treated accordingly. Bending the vibrating element willdestroy the instrument.10 OPTISWITCH 3300 C - with contactless electronic switch29960-EN-060112

MountingWarning:The housing must not be used to screw the instrument in!Applying tightening force on the housing can damage itsinternal mechanical parts.To screw in, use the hexagon above the thread.4.2 Mounting informationAgitators and fluidizationAgitators, equipment vibration, etc., can cause the level switchto be subjected to strong lateral forces. For this reason, do notuse an overly long extension tube for OPTISWITCH 3300 C,but check if you can mount a short level switch on the side ofthe vessel in horizontal position.Extreme vibration caused by the process or the equipment, e.g. agitators or turbulence in the vessel e.g. from fluidization,can cause the extension tube of OPTISWITCH 3300 C tovibrate in resonance. This leads to increased stress on theupper weld joint. Should a longer tube version be necessary,you can provide a suitable support or guy directly above thetuning fork to secure the extension tube.This measure applies particularly to applications in Ex areas.Make sure that the tube is not subjected to bending forcesthrough this measure.Inflowing materialIf OPTISWITCH 3300 C is mounted in the filling stream,unwanted switching signals can be generated. Mount OPTI-SWITCH 3300 C at a location in the vessel where no disturbinginfluence from e.g. filling openings, agitators, etc. can occur.This applies particularly to instrument types with longextension tube.29960-EN-060112OPTISWITCH 3300 C - with contactless electronic switch 11

Functional safety9 Functional safety9.1 GeneralValidityArea of applicationSafety functionRelevant standardsSafety requirementsThis safety manual applies to measuring systems consisting ofOPTISWITCH 3300 C vibrating level switches and integratedoscillator VB60C. The instrument corresponds to a subsystemof 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. Thesafe condition depends on the mode:llIn mode "max": condition "covered"In mode "min": condition "uncovered"l IEC 61508-1, -2, -4- Functional safety of electrical/electronic/programmableelectronic systemsThe failure limit values for a safety function, depending on theSIL class (of IEC 61508-1, 7.6.2)Safety integrity level Low demand mode High demand modeSIL PFD avg PFH4 >=10 -5 up to =10 -9 up to =10 -4 up to =10 -8 up to =10 -3 up to =10 -7 up to =10 -2 up to =10 -6 up to

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 measuring system) after afail-safe error 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, 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.For number values see paragraph "Safety-technical characteristics".If the "low demand rate" does not apply, the measuring systemas safety-relevant part system in "high demand mode" shouldbe used (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).For number values see paragraph "Safety-technical characteristics".Safe condition and fault descriptionThe safe condition of the measuring system is the switched offstatus (quiescent current principle):l VB60C (contactless electronic switch) -switch openA 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.30 OPTISWITCH 3300 C - with contactless electronic switch29960-EN-060112

Functional safetyA dangerous undetected failure exists if the measuring systemdoes not go to the defined safe condition when required by theprocess.Configuration 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. For this reason, carefully observe themounting and installation instructions in the operator's manual.It is especially important to make sure the mode setting (min./max.) is correct.9.4 Reaction during operation and in case offailurellllllThe adjustment elements must not be modified duringoperation.If modifications have to be made during operation, carefullyobserve the safety functions.Fault signals that may appear are described in theappropriate operating 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 exchanged, the manufacturer must beinformed (incl. a fault description).29960-EN-0601129.5 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.OPTISWITCH 3300 C - with contactless electronic switch 31

Functional safetyThe 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".In 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 systemwere determined by an FMEDA acc. to IEC 61508. Basis forthe calculations are component failure rates acc. to SN 29500.All values relate to an average ambient temperature of +40°C(+104°F) during operation.
