Alert num-
ber
Alert title Possible cause Recommended actions
A104 Calibration in Pro-
gress A calibration procedure is in proc-
ess. • Allow the procedure to complete.
• For zero calibration, you may abort the
calibration, set Zero Time to a lower val-
ue, and restart the calibration.
A105 Two-Phase Flow The line density is outside the user-
defined two-phase flow limits. • Check for two-phase flow.
• Check the live density reading against
the upper and lower two-phase flow
limit settings.
A106 Burst Mode Enabled HART burst mode is enabled. • No action required.
• If desired, you can set Alert Severity
Level to
Ignore .
A107 Power Reset Occur-
red The transmitter has been restarted. • No action required.
• If desired, you can set Alert Severity
Level to
Ignore
.
A108 Basic Event 1 On The process has triggered Basic
Event 1. • No action required.
• Review event configuration if you be-
lieve the event was triggered errone-
ously.
A109 Basic Event 2 On The process has triggered Basic
Event 2. • No action required.
• Review event configuration if you be-
lieve the event was triggered errone-
ously.
A110 Frequency Output
Saturated The calculated Frequency Output is
outside the configured range. • Check the Frequency Output scaling.
• Check process conditions. Actual condi-
tions may be outside the normal condi-
tions for which the output is config-
ured.
• Check for air in the flow tubes, tubes
not filled, foreign material in the tubes,
coating in the tubes, or other process
problems.
• Verify that the measurement units are
configured correctly for your applica-
tion.
• Purge the sensor tubes.
A111 Frequency Output
Fixed The Frequency Output has been
configured to send a constant val-
ue. • Cycling power to the meter or restart-
ing totalizers will restore the Frequency
Output to normal operation.
• Check whether the output is in loop test
mode. If it is, unfix the output.
• Check whether the output has been set
to a constant value via digital communi-
cation.
