CMS 2nd Release Version 2019

How enhanced features benefit your machine operation and maintenance work

Spectral bands

One of the important hallmarks of diagnostics is that specific machine faults can be identified in a spectrum by specific frequency components. A spectral band is the vibration content of a range of the important frequencies converted into a single scalar overall value (in RMS) so it can be trended. A change in amplitude of these spectral bands over time is typically a good indicator of a developing specific machine fault and its severity. An example is shown in Figure 2. The spectral bands can be applied independent from the VC-8000 hardware but require connection to an OSIsoft PI® server.

 

QuickView Links (Navigation Bookmarks)

In a plant-wide condition monitoring installation, there can be several machines in an alarm situation and you have to find out quickly why and take action. The bookmark function helps you achieve this.

An alarm is seen on the non-driven end of the pump in Figure 1. To find out more about what is causing the alarm, click on the SETPOINT® CMS icon below the pump.

You will then be linked to the relevant set of trend plots that are associated with the alarm situation. These plots can be saved. This allows you to save both the set of plots you need plus the corresponding timeline (the last 24 h) for diagnostics. As every link to the CMS has a URL, you can access this information from any web browser. Further diagnostic information can be found by clicking on the SETPOINT® CMS icons in this display.

 

 

Spectral lines: High resolution makes the difference

You're interested in a single tree rather than the entire forest? Maybe it is not enough to simply know that something is wrong with the machine but you don’t know what. Narrowband diagnostics can pinpoint many types faults and the SETPOINT® CMS high resolution capability of up to 12,800 spectral lines makes this possible. More lines, more details, better diagnosis.
