Alert num-
ber Alert title Possible cause Recommended actions
A102 Drive Overrange The drive power (current/voltage) is
at its maximum.
• Check the drive gain and the pickoff
voltage. See Section 10.22 and
Section 10.23.
• Check for foreign material in the proc-
ess gas or fluid, coating, or other proc-
ess problems.
• Check for fluid separation by monitor-
ing the density value and comparing
the results against expected density val-
ues.
• Ensure that the sensor orientation is ap-
propriate for your application. Settling
from a two-phase or three-phase fluid
can cause this alert.
A104 Calibration in Pro-
gress
A calibration procedure is in proc-
ess.
• Allow the procedure to complete.
A105 Two-Phase Flow The line density is outside the user-
defined two-phase flow limits.
• Check for two-phase flow. See
Section 10.21.
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.
A113 mA Output 2 Satura-
ted
The calculated mA output value is
outside the configured range.
• Check the settings of Upper Range Value
and Lower Range Value. See
Section 10.17.
• Check process conditions. Actual condi-
tions may be outside the normal condi-
tions for which the output is config-
ured.
• Check for foreign material in the proc-
ess gas or fluid, coating, or other proc-
ess problems.
• Verify that the measurement units are
configured correctly for your applica-
tion.
A114 mA Output 2 Fixed The mA output is configured to
send a constant value.
• Check whether the output is in loop test
mode. If it is, unfix the output.
• Exit mA output trim, if applicable.
• Check whether the output has been set
to a constant value via digital communi-
cation.
