Status alarms and recommended actions (continued)Table 10-2:
Alarm code Description Cause Recommended actions
A005 Mass Flow Rate Over-
range
The measured flow has
exceeded the maxi-
mum flow rate of the
sensor (ΔT greater than
200 µs).
• If other alarms are present, resolve those
alarm conditions first. If the current alarm per-
sists, continue with the recommended ac-
tions.
• Check your process conditions against the val-
ues reported by the flowmeter.
• Check for slug flow. See Section 10.25.
• Check the drive gain and the pickoff voltage.
See Section 10.26 and Section 10.27.
• Check for electrical shorts. See Section 10.28.
• Check the integrity of the sensor tubes.
• Contact Micro Motion.
A006 Characterization Re-
quired
Calibration factors have
not been entered and
the sensor type is incor-
rect.
• Verify that all of the characterization parame-
ters match the data on the sensor tag.
• Contact Micro Motion.
A008 Density Overrange The measured density
has exceeded
10 g/cm
3
.
• If other alarms are present, resolve those
alarm conditions first. If the current alarm per-
sists, continue with the recommended ac-
tions.
• Verify process conditions, checking especially
for air in the flow tubes, tubes not filled, for-
eign material in the tubes, or coating in the
tubes.
• Check for slug flow. See Section 10.25.
• If accompanied by an A003 alarm, check for
electrical shorts. See Section 10.28.
• Verify that all of the characterization parame-
ters match the data on the sensor tag.
• Check the drive gain and the pickoff voltage.
See Section 10.26 and Section 10.27.
• Perform a density calibration.
• Contact Micro Motion.
A009 Transmitter Initializing/
Warming Up
Transmitter is in power-
up mode.
• Allow the meter to warm up.
• Verify that the tubes are full of process fluid.
• Check the wiring between the sensor and
transmitter. See Section 10.10.
A010 Calibration Failure Many possible causes,
such as too much flow
through the sensor dur-
ing a calibration proce-
dure.
• If this alarm appears during zeroing, verify that
there is no flow through the sensor, then retry
the procedure.
• Cycle power to the meter, then retry the pro-
cedure.
