Imagine you’re sitting in your control room and suddenly your machine protection alert alarm comes on or trips – again. You send your technician down to the basement to check it, but what is the first thing that comes to your mind? Is it real this time? Or is it just an instrumentation error? Maybe vibration from a nearby machine starting up? Or were the alarm limits accidentally set too low? What should I do? Stop wasting your time and resources and learn how to validate your alarms with condition monitoring software.

Why are protection alarms “so 1960s”
In the past, monitoring alarm status in the older machine protection systems monitor was displayed only by LED indicators.
In today’s systems, we now have high-resolution screen displays that display a lot of monitoring information, but still, there is often small a small circle next to the vibration measurement tag that is representative of the LED’s from the 1960s. Just like the LED, it has only one bit of information. The problem with this is that the LED indicates that a signal has exceeded limits, but there is no additional information confirming it was caused by a machine fault or other condition.

Condition Monitoring and Protection Systems
One solution to better validate those alarms is by adding a condition monitoring system (CMS) to your protection system. For example, our VC-8000/SETPOINT ® CMS can help you to prevent a shutdown in the first place. Not only does it gives you an overview of the health of your machines without jeopardizing the protective function, but you can also develop a much better understanding of your alarms.
Using CMS with your protection system, not only can you validate protection alert alarms, but you can find out if a protection alarm will be true or false even before it occurs!
