Emerson Micro Motion 2500, Configuration And Use Manual

Page: 85 / 238

After verifying channel and output configuration, return the control loop to automatic
control.
6.2 Configure the mA Output
The mA Output is used to report the configured process variable. The mA Output
parameters control how the process variable is reported.
Your transmitter may have one or two mA Outputs:
• Channel A is always an mA Output (the primary mA Output).
• Channel B can be configured as an mA Output (the secondary mA Output).
Important
Whenever you change an mA Output parameter, verify all other mA Output parameters before
returning the meter to service. In some situations, the transmitter automatically loads a set of stored
values, and these values may not be appropriate for your application.

• Configure > Manual Setup > Inputs/Outputs > mA Output 2 > Secondary Variable
Overview
Use mA Output Process Variable to select the variable that is reported over the mA Output.
Prerequisites
• If you plan to configure the output to report volume flow, ensure that you have set
Volume Flow Type as desired:
Liquid or Gas Standard Volume .
• If you plan to configure an output to report a concentration measurement process
variable, ensure that the concentration measurement application is configured so
that the desired variable is available.
• If you are using the HART variables, be aware that changing the configuration of mA
Output Process Variable will change the configuration of the HART Primary Variable
(PV) and/or the HART Secondary Variable (SV).
Procedure
Set mA Output Process Variable as desired.
Default settings are as follows:
• Primary mA Output: Mass Flow Rate
• Secondary mA Output: Density
