Check Lower Range Value And Upper Range Value; Check Ma Output Fault Action - Emerson Micro Motion 5700 Configuration And Use Manual

• Channel D = Discrete Input 2
e) Return the remote input device to normal operation.
Postrequisites
• If the mA Output readings are within 20 microamps of the expected values, you can correct this
discrepancy by trimming the output.
• If the discrepancy between the mA Output readings is greater than 20 microamps, or if at any step the
reading was faulty, verify the wiring between the transmitter and the remote device, and try again.
• If the mA Input reading was slightly off at the transmitter, calibrate the mA signal at the remote input
device.
• If the Frequency Input reading was slightly off at the transmitter, calibrate the frequency signal at the
remote input device.
• If the Discrete Input readings are reversed, check the setting of Discrete Input Polarity.

17.28 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.

17.29 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.
