SmartDiagnostics® Feature Higlight: Alarms and Warnings

A key value of the SmartDiagnostics® Vibration Monitoring System (VMS) is that it facilitates exception-based monitoring of machine condition.  If you are implementing a facility-wide condition-based maintenance program, you may have a large number of machines to monitor on a regular basis.  Configure and apply monitoring bands with warning and alarm thresholds and the system can do much of that daily basic monitoring for you.  When VMS detects a machine's vibration level exceeding one of the thresholds, it automatically tells you of the event so that you can take action.

VMS indicates alert conditions in several ways to allow you to quickly, and easily, navigate to the machine that is having a problem and to see when and why the alert condition was raised.  In addition to it's system-wide alert log, VMS presents a dynamic alert icons on the navigation tree (see image at left) an alert bar on the trend chart (see above image), monitoring bands alert thresholds on the vibration data chart, and an alarm log for every monitoring location.

Let's look at dynamic alert icons.  Any time a vibration sample exceeds an alarm, or warning, threshold in one or more monitoring bands, an alert is generated and presented as an alarm icon, or warning icon on the monitoring band, monitoring location, machine and facility levels in the navigation tree.  If there are multiple alerts triggered at the same level of the navigation tree, the higher level will propagate up the tree to the next level.

The alert icons are dynamic and only show the alert level of the most recent vibration sample.  As such, if the machine temporarily exceeds a threshold vibration level and then returns to normal operation, the alert icon will show up briefly and then go away.  In this way, the alert icons on the navigation tree always give you a snap shot of the current state of your monitored equipment.
