Alarm Messages

The alarm message area displays vital information about the operation of the UPS system. During normal operation no alarm messages should be present. Alarm conditions can be monitored. The alarm messages are displayed in reverse video (highlighted— light on dark). To clear a latching alarm, you must also press the Alarm Reset pad after the alarm condition is corrected.

The following list shows the alarm messages that may be displayed in this area. For more information and the corrective actions for these messages, refer to Table 9 in this section.
