Duty Rotation

[Steve_D]

Guys, I am doing a pump station with 4 pumps, duty selectable, rotating etc etc etc. and the combinations are huge. Some of you guys would have done something similar and I was hoping someone would have some documentation or program PDFs (Im using "Fuji" so its a bit much to expect its done on this) to help me clarify the operation.

I just completed a similar project last week. 4 pumps, rotating out the cycles for each. All based on a drop in water pressure. Unfortunately, I only have access to the program at work and have no way of getting it here to my home computer (working for a large company, that kind of stuff is against the rules!). Sorry! Surely someone here has done something similar that they can post...?

Ron is a AB guy, but his explanations are top notch and the ideas are cross platform.
