The aim of this article is to provide you with some guidance as to how to best respond to MOVUS alarms, including what to do for the different types of alarm notifications, and what to look for when on the dashboard.
What to do with MOVUS Alarms
With either type of alarm notification (yellow advisory or red alert), MOVUS recommends checking out the Equipment Detail Page on the dashboard as your first action. This will help you understand the data coming from the FitMachine. If you are unsure about what you should be looking at on the dashboard, further down this article outlines What to look for in MOVUS Alarms.
It's important to understand that alarms can be sent for any variation in the equipment. For example, there are instances where the MOVUS AI responds to an operational change rather than a condition change, or the FitMachine may have trained on non-running data. This is why MOVUS recommends you look at the dashboard first. Understanding what you are likely to find when you get to the equipment is critical in planning appropriate resources.
To verify what the data on your dashboard indicates, recommendations for your next actions are below:
Red alerts: For red alerts, MOVUS recommends physically inspecting the equipment soon after looking at the data on the dashboard to get a more complete picture of why the deviation occurred.
Yellow advisories: For yellow advisories, MOVUS recommends keeping an eye on the equipment's data on the dashboard and using that to determine if a physical inspection is necessary.
Please note that the MOVUS system is designed to be an ‘early warning’ tool to alert you to changes in asset condition - it’s not a replacement for more detailed VA analysis, and the data should be validated and further investigated if you deem necessary. If you want to know more about yellow advisories or red alerts please follow these links.
What to look for in MOVUS Alarms
Below are two examples of AI trends that MOVUS recommends you investigate further. If the trend that you are seeing on the dashboard does not match these, please get in touch with MOVUS support here.
Accelerating, upward trend
This is the typical hockey-stick change in the overall vibration of a piece of equipment prior to failure, where a fault has progressed into the final stages, and is deteriorating at an accelerating rate. You may also see an increase in the temperature in a more serious situation.
For this type of trend, MOVUS doesn’t recommend shutting down the equipment immediately but does recommend visiting the equipment (if it is safe to do so) to determine if there’s been an observable change in the equipment.
Condition change with no related vibration change
These events are sometimes quite hard to understand as there doesn’t seem to be any real change in the vibration of the equipment, but the AI Condition has changed quite significantly. If you have a look at the alarms that are triggered by these types of events, the 3 dials will show you that the alarm was triggered primarily by a change in the Tone of the equipment.
AI Tone refers to the frequency profile of the vibration recorded by the FitMachine. E.g. Changing the bass or treble in an audio system will change the frequency profile.
