Zero to One Hundred in 0.8 Seconds

[hyperfocal]

As I understand it, running a 6100 in the 1 - 29% range is harmful to the pump; I've heard through the grapevine that it is okay to alternate from 0% and 30%+

Is that the case? How about on the 6055? I'm alternating the flow every 0.8 sec if that matters...

I believe Roger has mentioned that 30% is the minimum because typically the RPM's at that speed are about the amount required to continue rotation. If you set it lower, the pump will likely be stuttering and/or turning off due to too low of rotation speed.

 

[rvitko]

I take it you mean off to 30%? This would be OK. The speeds between 0% and 30% are the problem, just as RokieM said, there is not enough rotational speed to keep it steady, like a slow gyroscope.

 

[hyperfocal]

What I'd like to do is run it off to 100% every 0.8 seconds.

 

[rvitko]

I think that would be OK, that is basically what the Nano wavebox is doing but you should know that with such a short cycle it will probably never really reach 100%. It would probably take almost 2 seconds to reach full speed.

Thanks Roger, not reaching 100% is fine. I've experimented with both 0-100% and 30-100%, and the 0-100% gives a much larger wave-motion.

The 6100 takes 0-100% well, the 6055s don't seem to like it -- they click, so I'll keep them at 30-100%

 

[rvitko]

We made a design change to solve this click, when did you buy your pumps? It is a retrofittable change.

 

[hyperfocal]

I bought them back in Oct/Nov '07

 

[rvitko]

PM me your name and address, the drive unit didn't change to the new non clicking style until November.

Done, thanks Roger.

how are you going to get it to go to 0 then 100?

I have two 6100 and would love to have one side turn on 100 well the other side is 0 then reverse it. can this be done? I am running the 7094 controller.

Use Interval or Tide mode and plug one pump into the first socket and one into the last, set all your knobs to 100%. This would be off (0) to 100 every minute if you set a one minute interval.

 

[rogergolf66]

but in those setting the one in the first slot will never turn off right?

 

[rvitko]

No, it will, it will alternate back and forth, in sequence mode it won't turn off but in Interval (formerly called tide) it will.

 

[rogergolf66]

I don't have the manual for the 7094 is there a place where I can down load it?

Thanks Roger

 

[rogergolf66]

I found my manual but what I was looking for was not in it. What are the differnce simbles mean? pulse wave ect.... What one is what?

Thanks Roger

 

[rvitko]

The pulsed straight arrow is pulse flow, the two arrows pointed at each other (head to head) is tide mode, the arrows that are tip to tail are sequence.

 

[rogergolf66]

Got it thanks a bunch !!!!!

Thanks Roger, the spacer/impeller upgrade is working perfectly. Being able to drop to 0% makes a huge difference to wave production.
