9.3.8.2 Historic Events
More detailed information is displayed in the ‘History Events’ screen. In addition to the Power Module ID number and the text summary, the time
the event occurred and two data line codes are shown. Up to 500 events are stored in the ‘History Events’ screen. Refer to tables 9.6 – 9.8 for a
complete list of text summaries and explanations.
9.3.8.3 Reset All Events
WARNING
Tripp Lite does not recommend this action. Upon reset, diagnostic information will be lost and any warranty claims may
be affected.
The maintenance password (default 9999) is required to enter the “Reset All Events” screen. Select “Yes” to reset the events log. The data will
not be preserved once reset is selected.
