2.11 UPS Status Messages
The NX displays status changes as they occur in the current status window of the LCD, then later
stores that data in the history log, as shown in Figure 9.
• Current Status Window: The status messages are displayed chronologically and include the
date and time of the events. Three status messages are visible in the window at a time. To see
other messages, use the navigation keys to scroll up or down the list. A status message remains in
the current status area of the LCD until the status changes, when it is moved to the history log.
• History Log: When a record moves to the history log, the time the status changed is recorded.
The history log can hold up to 512 records. History log records may be viewed by accessing the
Records menu.

See Table 8 in Appendix A for a complete list of status messages, along with a description and any
