Status alarms and recommended actions (continued)Table 12-2:
Alarm code Description Recommended actions
A100 mA Output 1 Saturated The calculated mA output value is outside of the meter's config-
ured range.
1.
Check the Upper Range Value and Lower Range Value parame-
ters. Are they set correctly?
2. Check your process conditions against the values reported
by the flowmeter.
3. Verify that the measurement units are configured correctly
for your application.
4. Purge the flow tubes.
5. Verify process conditions, checking especially for air in the
flow tubes, tubes not filled, foreign material in the tubes, or
coating in the tubes.
A101 mA Output 1 Fixed Non-zero HART address configured, or the mA output is config-
ured to send a constant value.
1. Check whether the output is in loop test mode. If it is, unfix
the output.
2. Exit mA output trim, if applicable.
3. Check the HART polling address.
4. Check whether the output has been set to a constant value
via digital communication.
A102 Drive Overrange The drive power (current/voltage) is at its maximum.
1.
Check the drive gain and pickoff voltage.
2. Check for electrical shorts between sensor terminals or be-
tween the sensor terminals and the sensor case.
3. Check for partially filled tubes, tube fouling, damaged tubes,
and excessive air entrainment or flashing.
4. Settling from a two- or three-phase fluid could create this
alarm even if the flow tubes are full, which could mean the
sensor needs to be reoriented. Refer to the sensor installa-
tion manual for recommended sensor orientations.
A103 Data Loss Possible (Totals and
Inventories)
The totalizers are not being saved properly. The core processor
was unable to store the totalizers on the last power-down and
must rely on the saved totals. The saved totals can be as much as
two hours out of date.
1.
Make sure the transmitter and core processor are receiving
sufficient power.
2. Check the power supply and power supply wiring.
A104 Calibration in Progress A calibration procedure is in process.
A105 Slug Flow The density of the process has exceeded the user-defined densi-
ty limits. Check for slug flow (two-phase flow).
A106 Burst Mode Enabled HART burst mode is enabled.
A107 Power Reset Occurred The transmitter has been restarted.
A108 Basic Event 1 On No action required.
A109 Basic Event 2 On No action required.
