15.19 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 an Output Saturated alert for the
affected output, then perform the configured fault action.
Procedure
1. Record your current process conditions.
2. Check the configuration of the LRV and URV.

15.20 Check mA Output Fault Action

The 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.
Procedure
1. Check the status alerts for active fault conditions.
2. 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.
• Configure the transmitter to ignore the relevant status alerts or conditions.
Restriction
Some status alerts and conditions are not configurable.
3. If there are no active fault conditions, continue troubleshooting.

15.21 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 1250 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.

15.22 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.
