Can someone help me in the setup of the cascade program for the 2120? I need to collect data on some variable speed fans that are driven by VFD Drives.The fan speeds vary from 900rpm to 2300rpm. Looking for criticals. Any help will be greatly appreciated. Thank you

Mario,

I haven't used this program for a long time. Have you looked at Chater 10 of the 2120 User Manual? There is 20-pages of info..

Walt

unfortunetly Walt I don't have either the 2120 manual or the Cascade manual. Thank you for responding.

Mario
I do have the 2120 manual.
In my manual, Chapter 9 deals with the Cascade special function.
This program is loaded from the "special function" floppy (yes, floppy). From command line, you run the DOWNLOAD.BAT file (or from Windows, run the loadfw file).
In any case, it is a bit more to describe via this post. If you would like copies, contact me at my home email (ivibr8@yahoo.com) and I would be glad to make copies for you.
Regards, JP

p.s. this assumes you have this special-function program disc

Have you searched CSI's website for information?

Mario,
What you will need to do is basically to perform settings for an on-site reading as usual, the Fmin, Fmax and the LOR. This is followed by how often you would want the analyser to capture, be it using a tach trigger or time based. IF i am not mistaken, the maximum number of spectrums at one go i could gather is 155.
Once you press enter, sit back and let the csi do the rest.
Oh yeah, I forgot to mention that on the analyze mode, set it to cascade.

Hope this helps.

Wook thank you for your response. It is very helpfull. Thanks again.

wookp sorry about the mispelling.
