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.
To select Datalogger Event items:
To access the [Datalogger Events] option list press
Move the cursor to the desired item by pressing then to select it. Note that a plus
sign(+) appears before the item.
To de-select Datalogger Events:
Move the cursor to the desired item by pressing then . Note that this removes the
plus sign (+) from the item.
After selecting all desired items press to leave the [Datalogger Events] option list.
2.9.5 DISPLAY DATALOGGER
Use this menu cell to enable and format the on-screen datalogger. You can allow the report to scroll on
the screen with or without line wrapping. Selecting line wrap, forces a line feed after approximately 40
characters. This command is effective only after you select data items and the Datalogger has accu-
mulated some data.
To enable the on-screen datalogger display:
To access the [Display Datalogger] option list press
Move the cursor to the desired function.
To invoke the function press
To scroll the on-screen datalogger display:
To display one line at a time press
Use key to scroll down one screen (12 lines) at a time.
Use key to jump to the 12 lines of the last screen.
