Events And State Information - Liebert UPS System User Manual

5.5 Events and State Information:

Two kinds of UPS events and status information: Current events and historic events.
Current events are the current status information of UPS and the events that
happen only just now. The information will be displayed in the current event and
alarm display window in time sequence. If a certain status changes or a certain
event happens again, then the status or the event will disappear from the current
event and alarm display window and becomes the historic information.
Historic status information means the information that happens before and not exits
at the moment, or the information happens last time. These kinds of information will
be recorded in the history log in real time according to the time sequence. Each
history log has a start time and if the record is ended normally, there will be an end
time for the history log. If the end time is not recorded due to power failure, then the
historic log will have no end time.
