3.2 Principle of operationOPTISWITCH 5300 C is a point level sensor with tuning fork for point level detection.It is designed for industrial use in all areas of process technology and can be used in liquids. It is particularly suitable for applications with high temperatures up to 450 °C (842 °F) and high process pressure up to 160 bar (2320 psig).Typicalapplicationsareoverfillanddryrunprotection.Thesmalltuning fork allows use in pipelines, containers and tanks of all kinds. Thanks to its simple and rugged measuring system, OPTISWITCH 5300Cisvirtuallyunaffectedbythechemicalandphysicalpropertiesof the liquid.Itfunctionsevenunderdifficultconditionssuchasturbulence,foamgeneration, buildup, strong external vibration or changing products.

Function monitoringThe electronics module of OPTISWITCH 5300 C continuously moni-tors the following criteria via frequency evaluation:

• Strong corrosion or damage on the tuning fork• Loss of vibration• Break in the vibration drive circuit

If a malfunction is detected or in case of power failure, the electron-icstakesonadefinedswitchingcondition,i.e.therelaydeenergises(safe state).

The tuning fork vibrates at its mechanical resonance frequency of approx.1400Hz.Whenthetuningforkissubmergedintheproduct,the frequency changes. This change is detected by the integrated electronics module and converted into a switching command.

OPTISWITCH 5300 C can be operated without external evaluation system. The integrated electronics evaluates the level signal and out-puts a switching signal. With this switching signal, a connected device can be operated directly (e.g. a warning system, a pump etc.).Thedataforpowersupplyarespecifiedinchapter"Technical data".

4.1 General instructionsMake sure that all parts of the instrument coming in direct contact with the process, especially the sensor element, process seal and processfitting,aresuitablefortheexistingprocessconditions,suchas process pressure, process temperature as well as the chemical properties of the medium.Youcanfindthespecificationsinchapter"Technical data" and on the nameplate.

In general, OPTISWITCH 5300 C can be installed in any position. The instrument only has to be mounted in such a way that the tuning fork is at the height of the desired switching point.The tuning fork has lateral markings (notches) that indicate the switching point with vertical mounting. The switching point applies to water in conjunction with the basic setting of the density switch ≥0.7g/cm³(0.025lbs/in³).WhenmountingOPTISWITCH5300C,make sure that this marking is at the height of the requested switch-ing point. Keep in mind that the switching point of the instrument will shiftifthemediumhasadensityotherthanwater-wateris1g/cm³(0.036lbs/in³).Forproducts≤0.7g/cm³(0.025lbs/in³)and≥0.47g/cm³(0.017lbs/in³)thedensityswitchmustbesetto≥0.47g/cm³.Keepinmindthatfoamswithadensity≥0.45g/cm³(0.016lbs/in³)are detected by the sensor. This can lead to erroneous switchings, particulary when the sensor is used for dry run protection.

You can give your instrument additional protection against moisture penetration by leading the connection cable downward in front of the cableentry.Rainandcondensationwatercanthusdrainoff.Thisap-plies 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.

Fig. 7: Measures against moisture ingress

Caution:Do not hold OPTISWITCH 5300 C on the tuning fork. Particularly with flangeortubeversions,thetuningforkcanbedamagedjustbytheweight of the instrument. Transport coated instruments very carefully and avoid touching the tuning fork.Remove the packaging or the protective cover just before installation.

The vibrating level switch is a measuring instrument and must be treated accordingly. Bending the vibrating element will destroy the instrument.

Warning:The housing must not be used to screw the instrument in! Applying tightening force can damage internal parts of the housing.Use the hexagon above the thread for screwing in.

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.

4.2 Mounting instructionsThe thread and the seal on the threaded version of OPTISWITCH 5300 C correspond to DIN 3852 part 1, screwed plug Form B (seal-ing via metallic sealing edge).Use screw-in openings or screw-in sleeves according to DIN 3852 part 2.

48075-EN-151111

Make sure that with instruments with 1" NPT thread, the screw-in opening on the vessel has an inside diameter of at least 29.5 mm (1.16 in).To mount the sensor, proceed as follows:1. Screw the OPTISWITCH 5300 C into the mounting boss up to the

stop. You can determine the later position already before welding.2. Mark the position of the OPTISWITCH 5300 C on the mounting

boss.3. Mark the respective position of the mounting boss on the vessel

or pipeline.In case of lateral mounting, make sure the mark on the spanner flatofOPTISWITCH5300Cpointsupwards.When mounting in pipelines, make sure that the surfaces of the tuningforkareparalleltothedirectionofflow.

4. Remove the OPTISWITCH 5300 C from the mounting boss before welding.

5. Weld the mounting boss according to your marking.

Incaseofhorizontalmountinginadhesiveandviscousproducts,the surfaces of the tuning fork should be vertical in order to reduce builduponthetuningfork.Onthescrewedversionyouwillfindamarking on the hexagon. With this, you can check the position of the tuning fork when screwing it in.Inthecaseofflangeversions,theforkisalignedwiththeflangeholes.When used in adhesive and viscous products, the tuning fork should protrude into the vessel to avoid buildup. For that reason, sockets forflangesandmountingbossesshouldbeavoidedwhenmountinghorizontally.

Note:SealforinstrumentswithprocessfittingthreadThe thread and the seal form on the mounting boss correspond to DIN 3852, part 1, screwed plug Form B (sealing via metallic sealing edge). In this case, no seal is required.

Instruments for high temperatures have a temperature adapter be-tweenprocessfittingandelectronicshousing.Thisisusedforthermaldecoupling of the electronics from high process temperatures.

Information:The temperature adapter may be embedded in the vessel insulation only up to max. 50 mm (1.97 in). Only then is a reliable temperature decoupling guaranteed.

IfOPTISWITCH5300Cismountedinthefillingstream,unwantedfalse measurement signals can be generated. For this reason, mount OPTISWITCH 5300 C at a position in the vessel where no distur-bances,e.g.fromfillingopenings,agitators,etc.,canoccur.This applies particularly to instrument types with long extension tube.

Duetotheeffectsofagitators,equipmentvibrationorsimilar,thelevelswitch can be subjected to strong lateral forces. For this reason, do not use an overly long extension tube (optional) for OPTISWITCH 5300 C , instead check if it is possible to mount a short level switch OPTISWITCH5300Conthesideofthevesselinhorizontalposition.Extreme vibration caused by the process or the equipment, e.g. agitators or turbulence in the vessel, can cause a long extension tube of OPTISWITCH 5300 C to vibrate in resonance. This leads to increased stress on the upper weld joint. Should a longer tube version be necessary, you can provide a suitable support directly above the tuning fork to secure the extension tube.This measure applies mainly to applications in Ex areas of category 1GorWHGaswellastoshipclassifications.Makesurethatthetubeis not subject to bending stress due to this measure.

Fig. 10: Lateral suppot of OPTISWITCH 5300 C

The second seal of the gas-tight leadthrough (option) prevents an uncontrolled leakage of the medium. The service life of the gas-tight leadthrough depends on the chemical resistance of the materials. See "Technical data".

Caution:If it is determined (e.g. via an error message from OPTISWITCH 5300 C ) that medium has already penetrated into the vibrating element, the instrument must be exchanged immediately.

The signal lamp for indication of the switching condition of the relay.With the mode setting (4), the switching condition and hence the function of the signal lamp can be changed.

• YellowLEDlights=relayenergized• Green LED lights = operating voltage on

With the mode setting (min./max.) you can change the switching condition of the relay. You can set the required mode according to the "Function chart"(max.-max.detectionoroverflowprotection,min.-min. detection or dry run protection).

With this DIL switch (3) you can set the switching point to liquids havingadensitybetween0.47and0.7g/cm³(0.017and0.025lbs/in³).Withthebasicsetting,liquidswithadensityof≥0.7g/cm³(0.025lbs/in³)canbedetected.Inliquidswithlowerdensity,youmustsettheswitchto≥0.47g/cm³(0.017lbs/in³).Thespecificationsforthepositionoftheswitchingpointrelatetowater-densityvalue1g/cm³(0.036lbs/in³).Inproductswithadifferentdensity,theswitchingpointwill shift in the direction of the housing or tuning fork end depending on the density and type of installation.Optionally the instrument can be also delivered with a min. density rangeof≥0.42g/cm³(0.015lbs/in³).Inthiscase,themax.permis-sible process pressure is limited to 25 bar (363 psig). This instrument version may not be used in safety-instrumented systems (SIL) or in applications according to WHG.

Note:Keepinmindthatfoamswithadensity≥0.45g/cm³(0.016lbs/in³)are detected by the sensor. This can lead to erroneous switchings, particulary when the sensor is used for dry run protection.

Note:In case of intense boiling or bubbling processes as well as extreme outgassing, the density of the gas/product mixture at the product surface can be so low that it can't be detected by the sensor. This can cause erroneous switchings.
