Emerson MMI-20019043 Manuel D’Utilisation

Result: A change in the mass flow rate will be reflected in the mA output over a time period
that is greater than 3 seconds. The exact time period is calculated by the transmitter
according to internal algorithms which are not configurable.

mA Output Fault Action

 controls the behavior of the mA output if the transmitter encounters

an internal fault condition.

For some faults only: If Last Measured Value Timeout is set to a non-zero value, the transmitter will not
implement the fault action until the timeout has elapsed.

1.

Set mA Output Fault Action to the desired value.

The default setting is Downscale.

2.

If you set mA Output Fault Action to Upscale or Downscale, set mA Output Fault Level as
desired.

mA Output Fault Level

Upscale

Goes to the configured fault level

Default: 22.0 mA
Range: 21 to 24 mA

Downscale

 (default)

Goes to the configured fault level

Default: 2.0 mA
Range: 1.0 to 3.6 mA

Internal Zero

Goes to the mA output level associated
with a process variable value of 0 (zero),
as determined by Lower Range Value and
Upper Range Value
