Appendix E - E VENT T RACE
The Event Trace is a list of events recorded by the ventilator. These events may be normal
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)).
• Additional occurrences (3
rd
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 (i.e. the quantity of 2 will
be increased to 3).
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 14 -
Troubleshooting for more information.
REMARQUE
Les entrées du journal d’événements ne représentent que l’un des nombreux outils de diagnostic
utilisés pour localiser les pannes du ventilateur. Des informations supplémentaires sont souvent
nécessaires pour identifier de façon précise la source d’un problème. Reportez-vous au Chapitre 14 –
Dépannage, pour de plus amples informations.
