2.9.4 DATALOGGER EVENTS

System 1010 offers "event-based" data logging that operates concurrently with "time interval" based
data logging. The event-based function generates a Datalogger report upon the triggering of any of the
alarms. This is useful for recording transient alarms (e.g., a liquid interface, or a short aeration alert).
Note: An Alarm Event report will be generated imme-diately after the transition from a non-alarm to an
alarm event. The reverse situation (alarm state to non-alarm state) does not trigger the event-based
Datalogger.
Event-based Datalogger messages conserve memory. However, if you use this feature to monitor a
level such as Flow Alarm, set the alarm threshold high enough to avoid repetitive triggering. You must
select Site ID (Name) and Time to "time-stamp" the alarm events. Note that on the Datalogger report,
a [-] represents a reserved letter code space (inactive alarm) and a letter code represents an active
alarm.
