9 Diagnosis, Asset Management and serviceFault description Error pattern Cause Rectification7. Measured valuejumps towards 0 %during filling8. Measured valuejumps towards 100 %during filling9. Measured valuejumps sporadically to100 % during filling10. Measured valuejumps to ≥ 100 % or0 m distance40Level0Level0Level0Level0timetimetimetime– Amplitude of a multiple echo(vessel top - product surface) islarger than the level echo– The level echo cannot be distinguishedfrom the false echo ata false echo position (jumps tomultiple echo)– Due to strong turbulence andfoam generation during filling,the amplitude of the productecho sinks. Measured valuejumps to the false echo– Varying condensation or contaminationon the antenna– Level echo is no longerdetected in the close rangedue to foam generation or falseechoes in the close range. Thesensor goes into overfill protectionmode. The max. level (0 mdistance) as well as the statusmessage "Overfill protection"are outputted.– Check parameter "Application",especially vessel top, producttype, dished end, high dielectricfigure, adapt if necessary– Remove/reduce false echo:minimize interfering installationsby changing the polarizationdirection– Chose a more suitable installationposition– Carry out false signal suppression– Carry out a false signal suppressionor increase falsesignal suppression with condensation/contaminationin theclose range by editing– Check measuring site: Antennamust protrude out of the socket– Remove contamination on theantenna– Use a sensor with a more suitableantenna9.4 Measurement error during emptyingFault description Error pattern Cause Rectification11. Measured value remainsunchanged inthe close range duringemptying12. Measured valuejumps towards 0 %during emptyingLevel0Level0timetime– False signal larger than thelevel echo– Level echo too small– Echo from the tank bottomlarger than the product echo,for example, with products withε r< 2.5 oil-based, solvents– Remove false echoes in theclose range. Check: Antennamust protrude out of the socket– Remove contamination on theantenna– Minimize interfering installationsin the close range bychanging the polarizationdirection– After removing the false echoes,the false signal suppressionmust be deleted. Carry outa new false signal suppression– Check application parametersMedium type, Vessel height andFloor form, adapt if necessaryVEGAPULS WL 61 • 4 … 20 mA/HART - two-wire38061-EN-121011

The service itself is free of charge, the only costs involvedare the normal call charges.9.5 Software updateThe following components are required to update the sensor software:• SensorVoltage supply• Interface adapter VEGACONNECT 4PC with PACTware• Current sensor software as fileYou can find the actual sensor software as well as detailed informationof the procedure under "www.vega.com/downloads" and"Software".Caution:Instruments with approvals can be bound to certain software versions.Therefore make sure that the approval remains effective with asoftware update.You can find detailed information on www.vega.com/downloads and"Approvals".38061-EN-121011VEGAPULS WL 61 • 4 … 20 mA/HART - two-wire9.6 How to proceed in case of repairYou can find a repair form as well as detailed information on how toproceed under www.vega.com/downloads and "Forms and certificates".By doing this you help us carry out the repair quickly and without havingto call back for needed information.If a repair is necessary, please proceed as follows:• Print and fill out one form per instrument• Clean the instrument and pack it damage-proof41
