7. Select State Sensor because the contact closure sensor is a discrete
sensor, which indicates the environmental changes through the
status changes.
8. Select "Alarmed/Open/On" in the submenu since we want the action
"Activate Loading Shedding" to be taken when the selected contact
closure sensor changes its state related to the "alarmed" state.
9. In the "Trigger condition" field, select the Alarmed radio button
because we want the PX to respond to the event only when the
contact closure sensor enters the Alarm state.
A Note about Infinite Loop
You should avoid building an infinite loop when creating event rules.
The infinite loop refers to a condition where the PX keeps busy because
the action or one of the actions taken for a certain event triggers an
identical or similar event which will result in an action triggering one
event again.
Example 1
This example illustrates an event rule which continuously causes the PX
to send out email messages.
Event selected Action included
Device > Sending SMTP message
failed Send email
Example 2
This example illustrates an event rule which continuously causes the PX
to send out SMTP messages when one of the selected events listed on
the Device menu occurs. Note that <Any sub-event> under the Device
menu includes the event "Sending SMTP message failed."
Event selected Action included
Device > Any sub-event Send email
