Active Alerts

Field Communicator Service Tools > Active Alerts (3-1)
Visible if an alert is not active
No Active Alerts
Visible if an alert is active
Refresh Alerts—the following menu/methods will be visible only if the associated alert is active:
D F: Process Temperature Signal Failed - When active, indicates the process temperature sensor (RTD) reading has
exceeded the hardcoded limits (<10 ohms or >320 ohms). If this status message appears, reinstall the process
temperature sensor (RTD).
D F: Sensor Drive Failed - The Hall sensor drive current read­back is outside of the hard­coded limits.
D F: Sensor Signal Failed - The instrumentation amplifier output for the torque tube position is outside of range.
D M: Non‐Primary Variable Out of Limits - When active, indicates the process applied to a sensor, other than that of
the Primary Variable, is beyond the operating limits of the device. This indicates Electronics or Process
Temperature has reached or exceeded the associated temperature alert limits.
D M: Analog Output Saturated - The Analog Output value reported by the instrument is beyond the limits (3.8 or
20.5 mA) and no longer represent the true applied process.
D M: Processor Free Time Depleted - There is insufficient free time remaining in the execution period to complete
the scheduled tasks.
D M: NVM Write Limit Exceeded - When active, indicates the total number of writes to one of the three areas of
NVM has exceeded the hardcoded limit. Try cycling power to the instrument and see if it clears. If it does not
clear, replace the Electronics Module. If the Hall (Transducer) count is zero, replace the Transducer Module.
D A: Analog Output Fixed - The Analog Output is in Fixed Current Mode.
D A: Cold Start - A power failure or device reset has occurred.
D A: Instrument Temperature Too Low - When active, indicates that the Instrument Temperature has exceeded the
value of the Instrument Temperature Low Alert Threshold.
D A: Instrument Temperature Too High - When active, indicates that the Instrument Temperature has exceeded
the value of the Instrument Temperature High Alert Threshold.
D A: Process Temperature Too Low - When active, indicates that the Process Temperature has exceeded the value
of the Process Temperature Low Alert Threshold.
D A: Process Temperature Too High - When active, indicates that the Process Temperature has exceeded the value
of the Process Temperature High Alert Threshold.
D A: PV LoLo Alert - When active, indicates that the Process Variable has exceeded the value of the Process Variable
Low Low Alert Threshold. Analog Output set to jumper­selected alarm current.
D A: PV Lo Alert - When active, indicates that the Process Variable has exceeded the value of the Process Variable
Low Alert Threshold.
