GE B90 help

[B4rancher]

I’m looking for some reference material besides the pub itself that I can read to figure out more on the flex logic and programming on the B90. I have a few settings issues that I can’t take up directly with the creator, unknown, and with a little more insight I’m sure I can get through them. Eg, directional source and ct sat specs to name two. Thanks in advance!

What are yours questions about flex logic and programming? Can you give more information?

 

[B4rancher]

Source material besides the ever vague ge stuff.

You want something above the manual?? The manual is all you need....

Using logic and variables in the B90 is pretty straight forward if you check the manual.

If you can't explain it to a six year old, you don't understand it yourself.

I was asked to help someone with a UR relay a few years ago. The logic was quite sophisticated(a utility set up). I happened to be at a relay conference and asked the GE application engineer to take a look. His first glance was via the basic enervista SW. The GE guy then used a separate GE SW (Enervista Engineer?) to analyze things. It was very easy to see that most of the logic that seemed complicated was actually for utilization of the front panel push buttons and display. The Enervista Engineer SW at that time was $2-3k, but I just checked and it appears to be free now.

DTR2011, it don't work if flex logic was written by Enervista UR (not Engeener) and we want to add something else. We must use Engineer version before comissioning of device.
