RKL ATO switch

primo21 · Dec 18, 2015

Need help setting up my float switch on an RKL. It is a single float from autotopoff, that I have in the return section of my sump. I had it set up according to their instructions using the extension cord that you wire the float to by cutting one of the wires in the extension cord. This has been bullet proof since I got it. Now I wanted to wire it to my RKL and it has been anything but.

Been working on and off for the last week and yesterday dumped my whole ato container (~5 gal) into my sump. I need some help setting the programming up the right way. I have the pc4 outlet set to switch with the on device as swa on when closed, off device as none off when open. I also have a timer set to run for 5 sec then off for 3 hrs just in case, I guess it worked because my ato pump didn't burn out.

Do I need to take the float apart, it has the snail guard on it, to see if anything is stuck in there or is my setting wrong?

Any help is appreciated.

Your OFF device needs to be set as the float switch. (or SWA as you describe it). Leaving the OFF device set as "none" may be causing problems.

If you use a trigger timer the off device needs to be none. What type of pump are you using? Some like Aqualifter 's are known to stay on when they are suppose to be off on CH2 and CH3 of the PC4. If you have to use those outputs then add a surge protector between the PC4 and pump.

Old return, don't remember the name. I use the timer. So I should move it to outlet 1 or 4?

It would be a go idea if you are not sure. Make sure and test it while you are watching. There are examples of programming for this on DA'ss forum if you search for them. http://www.forum.digitalaquatics.com/index.php?sid=206c67802f3db691082f95be05933bce

So do you recommend using the on/off device or use on device then timer?

I used the timer with one float as you can limit the overall amount in a given time. Just do a search for ATO using single float switch on the DA forum.
