518 Diagnostics and servicingVEGADIS 82 • 4 … 20 mA/HART45300-EN-1707248 Diagnostics and servicing8.1 MaintenanceIf the instrument is used correctly, no maintenance is required innormal operation.8.2 Asset Management functionThe instrument supports the self-monitoring and diagnosis of the con-nected sensor. Status or failure messages are displayed according tothe sensor via display and adjustment module, PACTware/DTM andEDD.You can find a detailed overview of this function in the operatinginstructions of the respective sensor.The following table shows the error codes and text messages of theVEGADIS 82 and gives information on the cause and removal.CodeText messageReason RectificationS003CRC-error• CRC error during self-check • Carry out a reset• Send instrument for repairF008Sensor not found• Sensor is in the warm-upphase• HART communication ismalfunctioning• Check connection of the sensor• Check HART address of the sensorF013Sensor or measurementloop malfunctioning• Sensor signals error, novalid measured value • Check sensor parameter adjustment• Send instrument for repairF014Sensor input: Short-circuit• Short-circuit or sensorcurrent > 21 mA • Check cable• Check sensorF015Sensor input: Line break• Line break or sensorcurrent < 3.6 mA • Check cable• Check sensor, probably already in the run-in periodS021Scaling: Span too small• Scaling span too small • Carry out a fresh scaling, increase the distancebetween min. and max. scaling.S022Scaling: Value too high• Scaling value too high • Check scaling values and correct, if necessaryS030Measured value: not valid• Sensor in boot phase• Measured value not valid • Check sensor parameter adjustmentF034EEPROM: CRC error• EEPROM: CRC error • Switch the instrument off and on• Carry out reset to default setting• Send instrument for repairF035ROM: CRC error• ROM: CRC error • Switch the instrument off and on• Carry out reset to default setting• Send instrument for repairSensorsVEGADIS 82
