Error State
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:
n For 4 ... 20 mA output, the error level is 3.6 mA.
n 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 on pageî13.
Examples of situations that can cause the error state:
n The transmitter measures over 6000 ppm CO
2
.
n The CO
2
measurement module (GM10) is disconnected.
