To load the Diagnostic Frequency labels, you must check the Load Frequency
Labels checkbox in the Load Options dialog box.
Setting Up Speed References
The Dynamix 2500 data collector can determine the speed using speed references
in the Emonitor software. The speed reference value is used by the frequency
items to calculate the Fmax of the dependent measurements.
To set up speed references in the Emonitor software, double-click in the rpm
column in the Location pane.
The Machine Speed Setup dialog box appears.
You can choose a frequency reference item as your machine speed reference. This
allows for machine speeds to be stored and retrieved dynamically. The Dynamix
2500 data collector supports two types of frequency types: speed reference and
linear rotational.
If you want to use a collected measurement from the Dynamix 2500 data
collector to set the machine speed, you have two options:
• Use a manual entry process measurement to enter machine speed by
reading it from any instrument in your plant. The measurement can then
be referenced for the machine speed, and would be updated every time you
unload that measurement.
