Troubleshooting
A030 Incorrect Board
Typ e
The loaded software is not
compatible with the
programmed board type
• Contact Micro Motion. See Section 11.3.
A031 Low Power The transmitter is not
receiving enough power
• Check power supply to transmitter. See Section 11.4.
A032 Meter
Verification/Outputs
In Fault
Meter verification in
progress, with outputs set
to fault
• Allow the procedure to complete.
• If desired, abort the procedure and restart with outputs set
to last measured value.
A033 Sensor OK, Tubes
Stopped by
Process
No signal from LPO or
RPO, suggesting that
sensor tubes are not
vibrating
• Verify process. Check for air in the flow tubes, tubes not
filled, foreign material in tubes, or coating in tubes (see
Section 11.15).
A102 Drive Overrange/
Partially Full Tube
The drive power
(current/voltage) is at its
maximum
• Excessive drive gain. See Section 11.19.3.
• Check the sensor circuitry. See Section 11.20.
• If this is the only active alarm, it can be ignored. If desired,
reconfigure the alarm severity to Ignore (see Section 8.8).
A104 Calibration in
Progress
A calibration procedure is
in progress
• Allow the flowmeter to complete calibration.
• For zero calibration procedures, you may abort the
calibration, set the zero time parameter to a lower value,
and restart the calibration.
A105 Slug Flow The density has exceeded
the user-defined slug
(density) limits
• See Section 11.14.
A107 Power Reset
Occurred
The transmitter has been
restarted
• No action required.
• If desired, reconfigure the alarm severity to Ignore (see
Section 8.8).
A116 API: Temperature
Outside Standard
Range
The process temperature
is outside API-defined
extrapolation limits
• Verify process.
• Verify API reference table and temperature configuration.
See Section 8.13.
A117 API: Density
Outside Standard
Range
The process density is
outside API-defined
extrapolation limits
• Verify process.
• Verify API reference table and density configuration. See
Section 8.13.
A120 ED: Unable to Fit
Curve Data
The configured values for
density curves do not
meet accuracy
requirements
• Verify enhanced density configuration. See Section 8.14.
A121 ED: Extrapolation
Alarm
Enhanced density
calculations are outside
the configured data range
• Verify process temperature.
• Verify process density.
• Verify enhanced density configuration. See Section 8.14.
A131 Meter
Verification/Outputs
at Last Value
Meter verification in
progress, with outputs set
to last measured value
• Allow the procedure to complete.
• If desired, abort the procedure and restart with outputs set
to fault.
A132 Simulation Mode
Active
Simulation mode is
enabled
• Disable simulation mode. See Section 11.10.
A133 PIC UI EEPROM
Error
EEPROM data on the user
interface module is corrupt
• Contact Micro Motion. See Section 11.3.
