10.6 Status alerts, causes, and recommendations
Alert num-
ber Alert title Possible cause Recommended actions
A001 EEPROM Error The transmitter has detected a
problem communicating with the
sensor.
• Cycle power to the meter.
• Contact Micro Motion.
A002 RAM Error The transmitter has detected a
problem communicating with the
sensor.
• Cycle power to the meter.
• Contact Micro Motion.
A003 No Sensor Response The transmitter is not receiving one
or more basic electrical signals from
the sensor.
• Check the drive gain and the pickoff
voltage. See Section 10.22 and
Section 10.23.
A004 Temperature Over-
range
The RTD resistance is out of range
for the sensor.
• Check your process conditions against
the values reported by the device.
• Verify temperature characterization or
calibration parameters.
• Contact Micro Motion.
A006 Characterization Re-
quired
Calibration factors have not been
entered, or the sensor type is incor-
rect, or the calibration factors are
incorrect for the sensor type.
• Verify all of the characterization or cali-
bration parameters. See the sensor tag
or the calibration sheet for your meter.
• Contact Micro Motion.
A008 Density Overrange The line density is greater than
3 g/cm
3
(3000 kg/m
3
).
• If other alerts are present, resolve those
alert conditions first. If the current alert
persists, continue with the recommen-
ded actions.
• Check for two-phase flow. See
Section 10.21.
• Check for foreign material in the proc-
ess gas or fluid, coating, or other proc-
ess problems.
• Verify all of the characterization or cali-
bration parameters. See the sensor tag
or the calibration sheet for your meter.
• Check the drive gain and the pickoff
voltage. See Section 10.22 and
Section 10.23.
• Perform Known Density Verification.
• Check the tines for corrosion, erosion,
or deposition.
• Contact Micro Motion.
