When using the 0 –20 mA measuring range, the open wire detection diagnostics will alwaysread "FALSE."Channels ValueNumber of supply voltages 1 (X3, pin on connector 24V)Supply voltage +24 V 18…30 VDCVoltage monitoring Supply voltage OK status LED U > 18 VDCMaximum power acceptance 70 mACurrentin mAValue representationin μA0 …20 mA 0000…20000 Represented as a decimal value4 … 20 mA 4000…20000￫ Range and channel diagnostics must be taken into account inorder to ensure that the reading shown is being interpretedcorrectly.Diagnostics Measuring range in mA0 – 20 4 – 20Cable break – < 4 mA (diagnostics)Under Range – 0 … 4 mADisplay value Measured valueOver Range 20 …21 mAover current > 21 mADisplay value > 21 (no reading)
