The following sections highlight available triggers. The meter will use the programmed
limits set by the user. Every event and its corresponding parameters along with the date
and time of the occurrence are logged and available for display or retrieval.
Triggers are congured in the Setup page. Each trigger can have the following limits:
Upper Critical Limit•
Upper Cautionary Limit•
Lower Cautionary Limit•
Lower Critical Limit•
In addition, you can select:
If alarms are enabled for this data. •
If the limits simply trigger an event (not an alarm).•
If the alarm/event closes automatically when the value falls below the high limits or •
above the low limits. If not, a user must acknowledge the alarm to remove it from the
active list.
In addition, alarms and events will generate an RSS feed and can generate email and
alerts. See the Setup on the Web Pages chapter for setup details for triggers, I/O, and
E-mail.
