Unsuccessful AMA
1. The adjustable frequency drive enters into alarm mode. A description of the alarm can
be found in the Warnings and Alarms chapter.
2. "Report Value" in the [Alarm Log] shows the last measuring sequence carried out by
the AMA before the adjustable frequency drive entered alarm mode. This number
along with the description of the alarm will assist you in troubleshooting. If you contact
Xylem for service, make sure to mention the number and alarm description.
NOTE: Unsuccessful AMA is often caused by incorrectly registered motor nameplate data
or a too big difference between the motor power size and the adjustable frequency drive
power size.
