Emerson MMI-20019043 Manuel D’Utilisation

mA Output Fault Level

None

Tracks data for the assigned process vari-
able; no fault action

Not applicable

If you set mA Output Fault Action or Frequency Output Fault Action to None, be sure to set Digital
Communications Fault Action

 to None. If you do not, the output will not report actual process data,

If you set Digital Communications Fault Action to NAN, you cannot set mA Output Fault Action or Frequency
Output Fault Action

 to None. If you try to do this, the transmitter will not accept the configuration.

The frequency output is used to report a process variable. The frequency output
parameters control how the process variable is reported. Your transmitter may have zero
or one frequency output: Channel B can be configured as a frequency output or a discrete
output.

The frequency output parameters include:

•

Frequency Output Process Variable

•

Frequency Output Polarity

•

Frequency Output Scaling Method

•

Frequency Output Maximum Pulse Width

•

Frequency Output Fault Action

 and Frequency Output Fault Value

Whenever you change a frequency output parameter, verify all other frequency output parameters
before returning the flowmeter to service. In some situations, the transmitter automatically loads a
set of stored values, and these values may not be appropriate for your application.
