3. Exit the mA output trim, if applicable.
15.2.26 [102] Drive Overrange
Alert
Drive Over-Range
Cause
The drive power (current/ voltage) is at its maximum.
Recommended actions
1. Check your process conditions against the values reported by the device.
2. Check for air in the flow tubes, tubes not filled, foreign material in the tubes, coating in the tubes, or
other process problems.
3. Verify that the tubes are full of process fluid.
4. Check the drive gain and the pickoff voltage.
5. Check the sensor coils for electrical shorts. If you find problems, replace the sensor. .
Check for internal electrical problems
6. Ensure that the sensor orientation is appropriate for your application.
Settling from a two-phase or three-phase fluid can cause this alert even if the flow tubes are full.

Recommended actions
Allow the test to complete.
15.2.28 [105] Two-Phase Flow
Alert
Process Aberration
Cause
The line density is outside the user-defined two-phase flow limits.
Recommended actions
1. Check for two-phase flow.
