Appendix D - E
The Event Trace is a list of events recorded by the ventilator
conditions, such as turning the ventilator on or off, or alarm conditions such as HW FAULT or
HIGH PRES.

Initial occurrences of events are recorded the first time they occur after power up, along with
the date, time and associated data, if any.

A second occurrence of the same type of event (same event code) will be recorded as a
separate line item along with the latest date, time and associated data. The quantity of
occurrences is increased by one (1) (i.e. a quantity of two (2) will be displayed).
NOTE
Event log entries are only one of many diagnostic tools used to troubleshoot the ventilator.
Additional information is often required to accurately identify the root cause of a problem.
See Chapter 7 - Troubleshooting for more information.
NOTE
Additional occurrences (3 or more) of the same type of event will update the secondary
occurrence line items with the latest date, time, and associated data. The quantity of
occurrences will be increased by one (1) for each additional occurrence (e.g. a quantity of 2
will be increased to 3).
