VEGAPULS WL 61 - 4 … 20 mA/HART - two-wire

9 Diagnosis, Asset Management and serviceFailureThe following table shows the error codes and text messages in thestatus message "Failure" and gives information on the cause and howto eliminate it. Keep in mind that some specifications are only valid forfour-wire instruments and the electronics of VEGAPULS WL 61 cannotbe exchanged by the user.38061-EN-121011CodeText messageF013no measuredvalue availableF017Adjustmentspan too smallF025Error in thelinearizationtableF036No operablesoftwareF040Error in theelectronicsF080F105DeterminemeasuredvalueF113CommunicationerrorF125UnpermissibleelectronicstemperatureF260Error in thecalibrationCauseVEGAPULS WL 61 • 4 … 20 mA/HART - two-wire– Sensor does not detect anecho during operation– Antenna system contaminatedor defective– Adjustment not withinspecification– Index markers are not continuouslyrising, for examleunlogical value pairs– Failed or interrupted softwareupdate– Hardware defect– General software error– The instrument is still in thestart phase, the measuredvalue could not yet bedetermined– EMC interferences– Transmission error with theexternal communicationwith 4-wire power supplyunit– Temperature of the electronicsin the non-specifiedsection– Error in the calibration carriedout in the factory– Error in the EEPROMRectification– Check or correct installationand/or parameter adjustment– Clean or exchange processcomponent or antenna– Change adjustment accordingto the limit values (differencebetween min. andmax. ≥ 10 mm)– Check linearization table– Delete table/Create new– Repeat software update– Check electronics version– Exchanging the electronics– Send instrument for repair– Exchanging the electronics– Send instrument for repair– Separate operating voltagebriefly– Wait for the warm-up phase– Duration depending onthe version and parameteradjustment up to approximately3 min.– Remove EMC influences– Exchange 4-wire powersupply unit or electronics– Check ambient temperature– Isolate electronics– Use instrument with highertemperature range– Exchanging the electronics– Send instrument for repair35
