Emerson 9739 Manuel D’Utilisation

You can set URV below LRV. For example, you can set URV to 

50

 and LRV to 

100

.

The mA output uses a range of 4–20 mA or 0–20 mA to represent mA Output Process Variable.
Between LRV and URV, the mA output is linear with the process variable. If the process
variable drops below LRV or rises above URV, the transmitter posts an output saturation
alarm.

Each option for mA Output Process Variable has its own LRV and URV. If you change the
configuration of mA Output Process Variable, the corresponding LRV and URV are loaded and
used.

AO Cutoff

 (Analog Output Cutoff) specifies the lowest mass flow rate, volume flow rate, or

gas standard volume flow rate that will be reported through the mA output. Any flow rates
below AO Cutoff will be reported as 0.

AO Cutoff

 is applied only if mA Output Process Variable is set to Mass Flow Rate, Volume Flow Rate, or Gas

Standard Volume Flow Rate

. If mA Output Process Variable is set to a different process variable, AO Cutoff is

not configurable, and the transmitter does not implement the AO cutoff function.
