If the transmitter detects a serious hardware or software error, or the measured reading is well outside the scaled range, the analog outputs are
set into a defined error level instead of the measured result. The error level depends on the output type:
- For 4 ... 20 mA output, the error level is 3.6 mA.
- For 0 ... 10 V output, the error level is 11 V.
If the cause of the error is removed, the transmitter resumes normal operation of analog outputs. Some errors may require a reset of the transmitter to recover.
If the error state is caused by a measurement result being well outside the scaled output range, only affected channels are set to the error state. For more information, see Analog output overrange behavior.
Examples of situations that may cause the error state:
