Emerson Micro Motion 4200 - Configure the Ma Outputs

Channel Options
Channel B • mA Output 2
• Frequency Output 1 (default)
• Discrete Output 1
Restriction
You cannot configure Channel Type for Channel A and Channel B. Channel A is always mA Output 1.
Channel B is always mA Output 2.
Postrequisites
For each channel that you configured, perform or verify the corresponding output configuration. When the
configuration of a channel is changed, the channel's behavior will be controlled by the configuration that is
stored for the selected output type, and the stored configuration may not be appropriate for your process.
After verifying channel and output configuration, return the control loop to automatic control.
8.2 Configure the mA outputs
The mA outputs are used to report current values of process variables. The mA signal varies between 4 mA
and 20 mA in proportion to the current value of the assigned process variable.
Depending on your purchase order and channel configuration, your transmitter may have 1-2 mA outputs.
Channel A is always mA Output 1, and Channel B is always mA Output 2.
Note
Channel A also supports HART/Bell 202 communications, superimposed on the mA signal. HART is not
available on Channel B.
8.2.1 Configure mA Output Source
Display
Menu > Configuration > Inputs/Outputs > Channel x > I/O Settings > Source
ProLink III Device Tools > Configuration > I/O > Outputs > mA Output x
Field Communicator Configure > Manual Setup > Inputs/Outputs > Channel x > mA Output x > mAOxSource
mA Output Source specifies the process variable that is reported by 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.
Procedure
Set mA Output Process Variable as desired.
Defaults:
Integrate the meter with the control system Configuration and Use Manual
