Alarms are classified in two categories:
MAJOR Alarms are indications of a serious failure within the XM2-300HP , such as
a loss of output voltage or a failed battery charger. Any situation that causes output
failure is considered a Major Alarm. Major alarms require immediate action to correct
the failure. To correct major alarms, follow the Smart Display on-screen instructions.
MINOR Alarms indicate a less serious failure, such as defective dual RTS or loss of
utility power. Corrective action can be delayed for a short time. To correct, follow the
Smart Display on-screen instructions.
The alarm matrices on the following pages indicate the MAJOR/MINOR active
alarms, the probable cause, and troubleshooting items to check to correct the alarm
condition.
If only one alarm is active, the alarm list is bypassed and diagnostic information for the single active alarm
displays.
