i think that is how they work spruce, i have had to lower the cal on mine manually, because the auto cal wouldnt work with the vyair pump, but i have got it working now.

I think dave is having the problem that the flow controller stops the pump, but the pumps pressure switch doesnt cut in, meaning it will cycle every few seconds, but im pretty sure that this is the way the controllers work.


Spruce you are more than welcome. if you can fick this i will pay ya because there could be a flow controller for sale soon be quick because anytime now its going under the front weels of me van




PS

we didnt invite you to comment on this topic, only me and dave are allowed to post  

 
This is what my Varistream does. It keeps switching the pump on to see if the tap has been opened, but switches the pump off again once the controller draws more than the preset amperage. It does it ever couple of seconds.

i cant disconnect my controller easily, otherwise i would give it a go.

My pumps which were shurflo, have always done this, just flashed de, the contollers are designed that you dont need the pressure switch, and with out a pressure switch, the controller will never flash ps, because there isnt one to cut in.

There is no problem with your controller, that is just how they work, i cant see that the pumps are going to use much power when they cut in for a second when the de has cut in.

Are they actually running your batterys flat then?

Having your pump running on full power without the controller is going to drain the battery quicker than having a flow controller and having the pump cut every few seconds when the de has cut in.

right, i have just been out to the van, pump the pump on full, got the battery reading up and turned the flow on and it dropped 0.3v, then with the controller flashing D.E, the voltage dropped 0.1v for split second then went back up as soon as the pump stopped.

That 0.1v is hardly going to use any power over the course of the day.

Why dont you try leaving the controller flashing D.E for an hour and see how much the voltage actually drops over this period, im pretty sure it would hardly drop at all.

ok mate will give that ago tomorrow. i was just a bit worried about it taking so long to go to ps because it never did that on the shurflo pump witch was the 100psi 6.4 lt per min. dave

lee i just wanted to add thank you for all your help i hope i get it sorted cheers mate dave

[Lee GLS]

no problem, hope you get a solution you are happy with.

dave, i called vyair today to see if the pressure switches are adjustable, they arnt  , but they are supposed to be getting a new pressure switch in that cuts in at a lower psi, i think he said 80psi, this is probably what you need so that when the controller stops the pump, DE, the pressure switch should then cut in because it requires less pressure to activate.
