FAULT POSSIBLECAUSE ACTION

No output signal• Novoltagesupply• Transmitterpolarityreversed• Open circuit in electrical wiring

• Checkvoltagesupply• Connectcorrectly• Checkelectricaloutputconnection&wiring

Divergent zero point signal

• Diaphragm is damaged• Operatingtemperaturesaretoohigh/toolow

• Contactthemanufacturer;replacethedeviceif necessary

• Keeptothepermittedtemperaturesshownon the data sheet

Constant output signal with

changing pressure

• Mechanical overload due to over pressure• Electrical fault

• Replacethedevice;incaseofrepeatedfailure, consult the manufacturer

Fluctuating signal span

• TheremaybeasourceofEMCinterferenceinthesurroundingarea(e.g.afrequencyconverter)

• Removethesourceofinterference

Signal span drops / is too small

• Damagetothediaphragm,e.g.duetoim-pacts,abrasive/aggressivemedium;corro-siononthediaphragm/pressureconnection;transmissionmediumnotpresent.

• Contactthemanufacturerandreplacethedevice
