Alarm code
Description
Cause
Recommended actions
A006
Transmitter not
configured
Calibration factors
have not been entered
and the sensor type is
incorrect.
•
Verify characterization parameters.
•
Contact Micro Motion.
A008
Density overrange
The measured density
has exceeded 0 to 10
g/cm
3
•
If other alarms are present, resolve those
alarm conditions first. If the current alarm
persists, continue with the recommended
actions.
•
Verify process conditions, checking
especially for air in the flow tubes, tubes
not filled, foreign material in the tubes, or
coating in the tubes.
•
Check for slug flow. See Section 10.24.
•
If accompanied by an A003 alarm, check
for electrical shorts. See Section 10.27.
•
Verify characterization parameters.
•
Check the drive gain and the pickoff
voltage. See Section 10.25 and Section
10.26 .
•
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
Mechanical zero: the
resulting zero was
greater than 3 μs
Temperature/Density
calibration: many
possible causes
•
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
procedure.
A011
Calibration too low
Mechanical zero:
corresponds with high
reverse flow — a zero
magnitude (absolute
value) greater than 3
μs
Temperature/Density
calibration: many
possible causes
•
Verify that there is no flow through the
sensor, then retry the procedure.
•
Cycle power to the meter, then retry the
procedure.
