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.
