Troubleshooting
Table 10-2 Status alarms and recommended actions
continued
Alarm code Description Cause Recommended actions
A012 Calibration too high Mechanical zero:
corresponds with high
forward flow — the
resulting zero was
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.
A013 Zero too noisy Mechanical zero:
Unstable value exists
• Remove or reduce sources of
electromechanical noise (e.g., pumps,
vibration, pipe stress), then retry the
procedure.
• Cycle power to the meter, then retry the
procedure.
A014 Transmitter failed Many possible causes
• Cycle power to the meter.
• Contact Micro Motion.
A016 Line temperature
out-of-range The value computed
for the resistance
of the Line RTD is
outside limits
• Check the sensor wiring. See Section
10.27.1 .
• Verify process conditions.
• Contact Micro Motion.
A017 Meter RTD
temperature
out-of-range The value computed
for the resistance of
the Meter/Case RTD
is outside limits
• Check the sensor wiring. See Section
10.27.1 .
• Verify process conditions. Temperature
should be between –200
°
F and +400
°
F.
• Verify characterization parameters.
• Contact Micro Motion.
A018 EEPROM checksum
error
• Cycle power to the meter.
• Contact Micro Motion.
A019 RAM or ROM test error
• Cycle power to the meter.
• Contact Micro Motion.
A020 Calibration factors
unentered The flow calibration
factor and/or K1 has
not been entered since
the last master reset.
• Verify characterization parameters.
A021 Incorrect sensor type The sensor is
recognized as a
straight tube but the
K1 value indicates a
curved tube, or vice
versa.
• Verify characterization parameters.
