You create a Points Alert on a set of points with an average pressure threshold set at 50bar.
A short time later, a points swing occurs with an average pressure of 55bar. This causes the alert to fire, and the red alert icon is displayed in the Centrix alert list.
On the next swing, the set of points reports another swing with an average pressure of 45bar. The original alert is still active, but now the alert icon is shown in blue, indicating that the alert is still active, but the most recent points swing did not cause an alert.
Any future swings which cause an alert will cause the alert icon to return to its red colour. |
