Table 14-2: Status alerts, causes, and recommendations (continued)
Alert number Alert title Possible causes Recommended actions
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
Check the drive gain and Check the pickoff
voltage.
A004 Temperature
Overrange
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 Characterizatio
n Required
Calibration factors have not
been entered, or the sensor
type is incorrect, or the
calibration factors are
incorrect for the sensor
type.
• Verify all of the characterization or calibration
parameters. See the sensor tag or the calibration
sheet for your meter.
• Contact Micro Motion.
A008 Density
Overrange
Applies only to the active
calibration.
• If calibrated for specific
gravity or relative
density, the overrange is
greater than 3.0
• If calibrated for
molecular weight, the
overrange is greater
than 86.7 g/mol
• If other alerts are present, resolve those alert
conditions first. If the current alert persists,
continue with the recommended actions.
• Check for foreign material in the process gas or
fluid, coating, or other process problems.
• Verify all of the characterization or calibration
parameters. See the sensor tag or the calibration
sheet for your meter.
• Check the drive gain and the pickoff voltage. See
Check the drive gain and Check the pickoff
voltage.
• Perform Known Density Verification.
• Contact Micro Motion.
A009
Transmitter
Initializing/
Warming Up
Transmitter is in power-up
mode.
• Allow the meter to complete its power-up
sequence. The alert should clear automatically.
• If other alerts are present, resolve those alert
conditions first. If the current alert persists,
continue with the recommended 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 transmitter has an
internal power issue. Replace the transmitter.
