Red (alarm)
When a graphic element turns red, it means the object represented is currently in a known alarm condition. For example, the analog value received from a temperature or humidity sensor maybe above (or below) a configured alarm limit, or an alarm switch (filter status, for instance) maybe in the “off-normal” state (closed or opened).
During this period, an associated graphic element remains red (Figure 2-3
). Color returns to normal only when the alarm status condition ends.

Blinking Red (Unacknowledged Alarm)
When an element is both red and blinking, it means two things:
•
The object represented currently has an alarm status, and
•
This alarm needs to be acknowledged by a system user. (Note that not all alarm-capable objects are also configured to require acknowledgment.)
You (as a system user) may have been given alarm acknowledgment rights, along with a link to the alarm display. If so, you maybe able to find and acknowledge the associated alarm—this will stop the blinking effect. Your acknowledgment includes the time, date, and user (you) that acknowledged it. However, the element will remain red until the alarm condition is over.
Orange (fault)
When a graphic element turns orange, it means the object represented currently has a fault status. Less common than alarm status, a fault usually means the value received from a sensor or device is outside any reasonable (measurable) limits. This condition may occur from an open or shorted-connection in a sensor cable, for example.

During this fault period, the element will remain orange (Figure 2-4
). The color may return to normal only when the fault condition no longer applies—in some cases, an alarm status (red) color maybe seen first.
Note that elements do not blink while displaying a fault status.
