Check Lower Range Value and Upper Range Value

If the process variable assigned to the mA output falls below the configured Lower Range
Value (LRV) or rises above the configured Upper Range Value (URV), the meter will post a
saturation alert (A100 or A113), then perform the configured fault action.

Check mA Output Fault Action

mA Output Fault Action controls the behavior of the mA output if the transmitter encounters
an internal fault condition. If the mA output is reporting a constant value below 4 mA or
above 20 mA, the transmitter may be in a fault condition.

d. Connect a Field Communicator directly across the resistor and attempt to
communicate (poll).
If this test fails, the transmitter may need service. Contact Micro Motion.
Configure basic HART parameters
Using the Field Communicator with the transmitter
Record your current process conditions.
Check the configuration of the LRV and URV.
Configure Lower Range Value (LRV) and Upper Range Value (URV)
Check the status alerts for active fault conditions.
If there are active fault conditions, the transmitter is performing correctly. If you
want to change its behavior, consider the following options:
• Change the setting of mA Output Fault Action.
• For the relevant status alerts, change the setting of Alert Severity to Ignore.
Restriction
For some status alerts, Alert Severity is not configurable.
If there are no active fault conditions, continue troubleshooting.
