Alert num-
ber Alert title Possible cause Recommended actions
A009 Transmitter Initializ-
ing/Warming Up or
Significant Process
Instability
Transmitter is in power-up mode.
If this occurs after device startup,
measurement stability has dropped
below acceptable limits and the de-
vice is repeating its startup se-
quence.
• Allow the meter to complete its power-
up sequence. The alert should clear au-
tomatically.
• If other alerts are present, resolve those
alert conditions first. If the current alert
persists, continue with the recommen-
ded actions.
• Verify that the transmitter is receiving
sufficient power.
- If it is not, correct the problem and
cycle power to the meter.
- If it is, this suggests that the trans-
mitter has an internal power issue.
Replace the transmitter.
• Ensure that the process fluid is stable.
Check for two-phase flow, high process
noise, or a fast transition between two
fluids of different densities.
A010 Calibration Failure Many possible causes.
This alert will not clear until you cy-
cle power to the meter.
• Ensure that your calibration procedure
meets the documented requirements,
cycle power to the meter, then retry the
procedure.
A014 Transmitter Failure Many possible causes. • Ensure that all wiring compartment
covers are installed correctly.
• Ensure that all transmitter wiring meets
specifications and that all cable shields
are properly terminated.
• Check the grounding of all compo-
nents. See Section 10.3.
• Evaluate the environment for sources of
high electromagnetic interference
(EMI) and relocate the transmitter or
wiring as necessary.
• Contact Micro Motion.
A016 Sensor Temperature
(RTD) Failure
The value computed for the resist-
ance of the line RTD is outside lim-
its.
• Check your process conditions against
the values reported by the device.
• Contact Micro Motion.
A020 Calibration Factors
Missing
Some calibration factors have not
been entered or are incorrect.
• Verify all of the characterization or cali-
bration parameters. See the sensor tag
or the calibration sheet for your meter.
A021 Transmitter/Sensor/
Software Mismatch
The configured board type does not
match the physical board.
• Verify all of the characterization or cali-
bration parameters. See the sensor tag
or the calibration sheet for your meter.
• Ensure that the correct board is instal-
led.
