3.2 Principle of operationVEGACAL 66 is a level sensor with fully insulated probe forcontinuous level measurement.The electronics functions acc. to the admittance principle(phase-selective admittance processing).It is designed for industrial use in all areas of processtechnology and can be applied in all areas of industrial processmeasurement.Fully insulated probes such as VEGACAL 66 are used inliquids and solids; preferably in conductive products.The probe, the measured product and the vessel wall form anelectrical capacitor. The capacitance is influenced by threemain factors:

1

Fig. 2: Functional principle - Plate capacitor1 Distance between the electrode surfaces2 Size of the electrode surfaces3 Type of dielectric between the electrodes

The probe and the vessel wall are the capacitor plates. Themeasured product and the insulation are the dielectric. Due tothe higher dielectric constant (DK value) of the insulation andthe conductive product compared to air, the capacitanceincreases as the product gradually covers the probe.The capacitance as well as the resistance change areconverted in the oscillator into a level-proportional signal.Two-wire electronics 4 … 20 mA/HART for power supply andmeasured value transmission on the same cable.

4 Mounting4.1 General instructionsSelect an installation position you can easily reach formounting and connecting as well as later retrofitting of anindicating and adjustment module. The housing can be rotatedby 330° without the use of any tools. You can also install theindicating and adjustment module in four different positions(each displaced by 90°).With screwed versions, the housing must not be used forscrewing in! Tightening can cause damages on the lockingpiston of the housing.To screw in, use the hexagon above the thread.Use the recommended cable (see chapter "Connecting topower supply") and tighten the cable gland.You can give your VEGACAL 66 additional protection againstmoisture penetration by leading the connection cable down-ward in 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. 3: Measures against moisture penetration

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.

Insulating measures, such as e.g. covering the thread withteflon tape, can interrupt the necessary electrical connectionwith metal vessels. For this reason, ground the probe on thevessel or use a conductive seal material.Metal vesselMake sure that the mechanical connection of the probe to thevessel is electrically conductive to ensure sufficient grounding.Use conductive seals such as e.g. copper or lead etc.Insulating measures, such as covering the thread with Teflontape, can interrupt the necessary electrical connection withmetal vessels. For this reason, ground the probe on the vesselor use a conductive seal material.Non-conductive vesselIn non-conductive vessels, e.g. plastic tanks, the second poleof the capacitor must be provided separately, e.g. in the formof a concentric tube.If possible, the capacitive probe should be mounted verticallyor parallel to the counter electrode. This applies particularly tonon-conductive products.In cylindrical tanks, spherical tanks or other asymmetrical tankforms, nonlinear level values are generated due to the varyingdistance to the vessel wall.Use a concentric tube in non-conductive products or linearizethe meas. signal.

4.2 Mounting informationDuring operation, the probe must not touch any installations orthe vessel wall. The measured value can also change if thedistance to the vessel wall changes considerably. If necessary,secure the end of the probe (insulated).In the gravity weight there is a thread (M12), e.g. for a ring bolt(article no. 2.27424). The thread is already insulated in thegravity weight.Make sure that the probe cable is not completely taut. Avoidtensile loads on the rope.

In vessels with conical bottom it can be advantageous tomount the sensor in the center of the vessel, as measurementis then possible down to the lowest point of the vessel bottom.

Caution:It is not possible to measure on the gravity weight. Themeasuring range of the probe ends at the upper edge of thegravity weight.

If VEGACAL 66 is mounted in the filling stream, unwantedfaulty measurements may be generated. Mount VEGACAL 66at a location in the vessel where no disturbing influence from e.g. filling openings, agitators, etc. can occur.This applies to all instrument types with long probe.

5 Connecting to power supply5.1 Preparing the connectionAlways observe the following safety instructions:l Connect only in the complete absence of line voltagel If overvoltages are expected, overvoltage arresters should

be installed.Tip:We recommend VEGA overvoltage arresters ÜS-F-LB-I andÜSB 62-36G.X.

In hazardous areas you should take note of the appropriateregulations, conformity and type approval certificates of thesensors and power supply units.

Power supply and current signal are transmitted via the sametwo-wire connection cable. The power supply range can differdepending on the instrument version. The exact range isstated in the "Technical data" in the "Supplement".Provide a reliable separation between the supply circuit andthe mains circuits acc. to DIN VDE 0106 part 101. The VEGApower supply units VEGATRENN 149AEx, VEGASTAB 690,VEGADIS 371 as well as all VEGAMETs meet this require-ment.Bear in mind the following factors regarding supply voltage:l the reduction of the output voltage of the power supply unit

under nominal load (with a sensor current of 20.5 mA or22 mA in case of fault signal)

l the influence of additional instruments in the circuit (seeload values in "Technical data").

VEGACAL 66 is connected with standard two-wire cablewithout screen. An outer cable diameter of 5 … 9 mm ensuresthe seal effect of the cable entry. If strong electromagneticinterference is expected, we recommend the use of screenedcable.When using VEGACAL 66 with cable entry 1/2" NPT andplastic housing, a metal 1/2" threaded insert is moulded intothe plastic housing.

30036-EN-050923

No grease should be used when screwing the NPT cablegland or steel tube into the threaded insert. Standard greasecan contain additives affecting the connection betweenthreaded insert and housing. This will influence the stability ofthe connection and the tightness of the housing.

If screened cable is necessary, connect the cable screen onboth ends to ground potential. In the sensor, the screen mustbe connected directly to the internal ground terminal. Theground terminal outside on the housing must be connected tothe potential equalisation (low impedance).If potential equalisation currents are expected, the connectionon the evaluation side must be made via a ceramic capacitor(e.g. 1 nF, 1500 V). The low frequency potential equalisationcurrents are thus suppressed, but the protective effect againsthigh frequency interference signals remains.Take note of the corresponding installation regulations for Exapplications. In particular, make sure that no potential equal-isation currents flow over the cable screen. In case ofgrounding on both sides this can be achieved by the use of acapacitor or a separate potential equalisation.

5.2 Connection procedureProceed as follows:1 Unscrew the housing cover2 If an indicating and adjustment module is installed, remove

it by turning it slightly to the left.3 Loosen compression nut of the cable entry4 Remove approx. 10 cm (4 in) of the cable mantle, strip

approx. 1 cm (0.4 in) insulation from the ends of theindividual wires

5 Insert the cable into the sensor through the cable entry6 Lift the opening levers of the terminals with a screwdriver

VEGACAL 66 measures the capacitance of the respectiveproduct. To display the actual level of the product, anallocation of the measured capacitance to the percentageheight must be carried out. For this adjustment, the capaci-tance is entered with emptied and filled vessel.If the vessel cannot be emptied or filled completely, you cancarry out the adjustment also with two known levels - forexample with 10 % and 90 %. The difference between theempty and full adjustment values should be as large aspossible.The actual level can then be calculated on the basis of thesesettings.VEGACAL 66 must be installed. A change of level isnecessary for this adjustment.In the main menu item "Basic adjustment", the individualsubmenu items should be selected one after the other andprovided with the correct parameter values.

8 Maintenance and fault rectification8.1 MaintenanceWhen used as directed in normal operation, VEGACAL 66 iscompletely maintenance-free.

8.2 Fault rectificationVEGACAL 66 offers maximum reliability. Nevertheless faultscan occur during operation. These may be caused by thefollowing, e.g.:l Sensorl Processl Power supplyl Signal processing.The first measures to be taken are to check the output signalas well as evaluate failure messages via the indicating andadjustmentmodule PLICSCOM. The procedure is described inthe following. Further comprehensive diagnostics options canbe carried out with a laptop with the software PACTware™ andthe suitable DTM. In many cases, the causes can bedetermined in this way and faults can be rectified.Should these measures not be successful, please call inurgent cases the VEGA service hotline under the phonenumber +49 1805 858550.The hotline is available to you 7 days a week round-the-clock.Since we offer this service world-wide, the support is onlyavailable in the English language. The service is free ofcharge, only the standard telephone costs will be charged.Connect a hand-held multimeter with a suitable measuringrange. For this, you have to disconnect the signal cable.?

8.3 Exchanging the electronicsIf the electronics module is defective, it can be replaced by theuser.In Ex applications, only instruments and electronics moduleswith appropriate Ex approval may be used.

If there is no electronics module available on site, it can beordered from the responsible VEGA agency.The order data of the sensor must be loaded into the newoscillator. This can be done either:l at the factory by VEGA personnell or on site by the user.In both cases, the sensor serial number is necessary. Theserial numbers are stated on the type label of the instrument oron the delivery note.

Information:When loading on site, the order data must be downloaded fromthe Internet (see Operating Instructions manual of theoscillator).

The oscillators are adapted to the respective sensor and differin their signal output or in their power supply. You can find asuitable oscillator in the following overview.The oscillators differ only in their signal output and are suitablefor all series 60 sensors.The following types are available:l CL-E60H (4 … 20 mA/HART)l CL-E60P (Profibus PA)l CL-E60F (Foundation Fieldbus)In Ex applications, only electronics with appropriate Exapproval must be used.
