UFM 3030 25
4.4 Namur NE 43 settings
The UFM 3030…EEx and UFC 030…EEx can be set-up such that the Current Output functions are
according to Namur NE 43. This means the current will go either to 3.6 or to 21.5 mA (failure value
can be user defined, normal operating limits are between 3.8 and 20.5 mA) in case the instrument
indicates a failure.
When the failure is no longer indicated, the instrument will automatically return to the measured
current output again. For a full description of the failure please refer to the “Short form Operating
and installation instructions.”
Standard each Namur device is programmed to give a 3.6 mA output in case of failure.
