The Running Cut-off is the vibration mm/s value assigned to a piece of equipment that will assist in separating running samples from ambient noise and vibration. The Cut-off is indicated by the red line on the Measured Data Graph and the value is given to the right of the graph, shown above.
This line is used to determine which samples are from running equipment as is of critical importance to the MOVUS AI. The Running Cut-off must be correctly set in order for the Calibration process to be completed properly otherwise the 'normal' running operation that has been learned will not be an accurate representation of your equipment.
Incorrect placement of this line will also have an effect on the data shown in the Utilisation graph, the Inferred power usage calculation as well as the machine running indicator. Therefore it's once again worth saying that it is of critical importance that the Running Cut-off is correctly positioned for each of your equipment.
By default the Running Cut-off is set at 0.2 mm/s for all newly onboarded sensors which we have found is generally a good position to start for standalone equipment.
For some installations where there are multiple pieces of equipment linked to the same process, such as the 3 pumps shown in the photo below, the vibrations from one pump can be detected by a FitMachine installed on one of the adjacent pumps. Adjusting the Running Cut-off gives you the ability to isolate the vibration of one piece of equipment from another by setting the cut-off high enough to ignore the vibrations propagating through the ground or pipes in some cases.
Adjusting the Running Cut-off of your Equipment
To adjust the running cut-off of your equipment you'll need to sign in to the Dashboard as an Administrator and on the 'Devices' page find your equipment and press the 'Edit' button. You'll be redirected to a page titled 'Edit Device'. You can also press the 'Edit' button on the Detailed View page of the chosen equipment.
Scroll to the bottom of this page and press the 'Next' button in the bottom right corner and press 'Next' again on the following page. Scroll to the bottom of the third page to find the Running Cut-off field where you can adjust the vibration level (in mm/s) that above which will tell the MOVUS AI when your equipment is running.
Be careful when adjusting the Running Cut-off that you do not set it so high that your equipment running data is skewed or discontinuous during operation which will affect the Calibration process, leading to an inaccurate representation of the 'normal' running condition.
