A021

Unrecognized/ 
Unentered Sensor 
Type

The sensor is recognized 
as a straight tube but the 
K1 value indicates a 
curved tube, or vice versa.

• Check the characterization. Specifically, verify the FCF 

and K1 values. See Section 4.2.

• Check the sensor RTD circuitry. See Section 10.24.
• If the problem persists, contact Micro Motion.

Failure

Transmitter electronics 
failure

• Cycle power to the flowmeter.
• Contact Micro Motion. 

PIC/Daughterboard 
Communication 
Failure

A030

Hardware/Software 
Incompatible

The loaded software is not 
compatible with the 
programmed board type.

• Contact Micro Motion. 

Incorrect Board 
Type

A031

Undefined

The transmitter is not 
receiving enough power.

• Check power supply to transmitter. See Section 10.14.1.
• If the alarm is appearing and disappearing frequently, 

check the mA Fault Action setting. If it is set to Upscale: 
consider a lower setting for fault level, consider changing 
the fault action to another setting (e.g., Internal Zero), or 
consider increasing the power supply to the transmitter. 
See Section 10.7.

Low Power

A033

Tube Not Full

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.

Tube Not Full

A100

Primary mA Output 
Saturated

The calculated amount of 
current output is outside of 
the linear range.

• See Section 10.18.

Primary mA Output 
Saturated

A101

Primary mA Output 
Fixed

Non-zero HART address 
configured, or user has 
fixed the mA output.

• Check the HART address. If non-zero, enable Loop 

Current Mode parameter. See Section 10.19.

• Exit mA output trim. See Section 7.4.
• Exit mA output loop test. See Section 7.3.
• Check to see if the output has been fixed via digital 

communication. 

Primary mA Output 
Fed

A102

Drive Over-Range

The drive power 
(current/voltage) is at its 
maximum

• Excessive drive gain. See Section 10.23.2.
• Check the sensor circuitry. See Section 10.24.
• If this is the only active alarm, it can be ignored. If desired, 

reconfigure the alarm severity to Ignore (see 
Section 5.3.1).

Drive Overrange

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.

Slug Flow

The density has exceeded 
the user-defined slug 
(density) limits.

• See Section 10.17.
