Check The Scaling Of The Frequency Output; Check Frequency Output Mode; Check Hart Burst Mode; Check Hart Communications - Emerson Micro Motion 5700 Configuration And Use Manual

Troubleshooting
March 2019
• For the relevant status alerts, change the setting of Alert Severity.
• Configure the transmitter to ignore the relevant status alerts.
Restriction
Some status alerts and conditions are not configurable.
3. If there are no active fault conditions, continue troubleshooting.

17.21 Check the scaling of the Frequency Output

If the process variable assigned to the Frequency Output goes to a value that would set the Frequency Output
to a signal below 0 Hz or above 12500 Hz, the meter will post an Output Saturated alert for the affected
output, then perform the configured fault action.
Procedure
1. Record your current process conditions.
2. Adjust the scaling of the Frequency Output.

17.22 Check Frequency Output Mode

If the transmitter is configured for two Frequency Outputs, and Frequency Output Mode is not configured
correctly for your application, the Frequency Outputs may exhibit unexpected behavior.
Frequency Output Mode is used only to define the relationship between two Frequency Outputs. If your
transmitter is not configured for two Frequency Outputs, Frequency Output Mode is not causing your output
problem.
Procedure
Verify the configuration of Frequency Output Mode.

17.23 Check HART burst mode

HART burst mode is normally disabled, and should be enabled only if a HART Triloop is being used.
Procedure
1. Check to see if burst mode is enabled or disabled.
2. If burst mode is enabled, disable it.

17.24 Check HART communications

If you cannot establish or maintain HART communications, or if the primary mA output is producing a fixed
value, you may have a wiring problem or a HART configuration problem.
