Stop DOS automatic water change when saltwater barrel is low

[kelleymc]

I can’t find the answer and hoped someone here can help.

I have an Apex Dos setup to perform automatic water changes. I also have an optical sensor in my Brute can to indicate when the water gets low.

Can someone share the code that I can add that will stop the water change once the level of new saltwater in the Brute can runs low?

Thank you!

I don’t know it exactly, but if you go to Neptune support they will give it to you, or they can come online and do it for you. Really great that way.

In the dos head setting add if ‘’brute can optical’’ closed then off

Sounds like it would work! But where do I enter that? I’ve only ever added alarm/alert codes.

Here is what I found on mine. Just determine if the optical switch is open or closed when above water line. Not sure, but I have them in my sumps to shut down skimmer if water level too high to keep it from overflowing.

I’ll give it a try, thanks!!

Here is my dos setting also.
You need to know which way you sensor is. Open or closed when it's empty.



My float switch is named awc_lo
I have it normally closed so if it fails it will go open and shut down the AWC.

HTH

I assume you have what you need based on reading. Don’t forget to set it up for both the “in” and “out” DOS pumps!!

Yes, hope he reversed the direction of the out pump.

 

[srobertb]

Yes, hope he reversed the direction of the out pump.

You can just reverse the water lines. The graph won’t be as pretty though.

 

[kelleymc]

Thanks guys, yes I did just reverse the water lines. The water changer is working great, just want to make sure it shuts down if I ever forgot to keep the Brute can full.

 

[kelleymc]

I REALLY want to make sure I have this right, appreciate everyone's help!

I would add this code to both the DOS_ADD and DOS_REMOVE pumps.

Fallback OFF
Set ON
If SaltLo OPEN then OFF

The optical sensor name is SaltLo and submerged (CLOSED) until the Brute can runs low, then would be OPEN.

Would that be correct?

That is correct. You can test this by manually moving the optic sensor out-of the water and observing the dos.

 

[kelleymc]

Thank you all!

I may not have been clear enough. I just added the code above and the DOS starting running. It seems to have overridden my automatic water change schedule.

Ok, did you have tdata code (dos schedule) there previously?

That shouldn't have been deleted.
Simply redo the schedule and add
If SaltLo OPEN then OFF
at the end of the code.

No, the box is empty, there was no code when I added that.

I've noticed that sometimes going from the wizard to advanced clears the data. I'm not sure why it does that. And when you save the information in advanced section all the scheduling is lost.

Repopulate the schedule in wizard, save it, and then move to advanced. There should be a line of code that starts with tdata. Below that set of code add your optic sensor code and save it.

 

[kelleymc]

Received a response from Neptune, they're saying just add "If SaltLo OPEN Then OFF" to the box, nothing else.

 

[kelleymc]

Hopefully the schedule still works, its showing TBL.
