ATO based off salinity

[dazza1304]

Hi guys,

Was hoping someone here could help.

I would like to perform ATO based off salinity.

What I would like to do is set the controller so that when my salinity reaches 35.2ppt consistently for x mins, it will activate one of my relay box outputs for x seconds (which will pump in RO water) .

Can anyone help with the coding for this please?

Thanks Roberto,

OK, I am a Reef Angel Novice, and with the Reef Angel wizard have basically used the system "out of the box".

So, I am guessing that I would get my current code up on the arduino software and paste in the different bits from above?

I can see the bit that relates to 35.2ppt salinity, but can you point me to the bits that define:

time that salinity is at 35.2 or greater (ideally I would like to be maybe 10 - 60 secs before the port is triggered - this is to "debounce the signal")

Actual time that the port will be activated - also would it be possible to set this such that the pump runs for x seconds or the salinity reaches 35ppt for y seconds - which comes first?

Sorry if they are stupid questions, but I guess I have to learn somewhere!!

Your help would be much appreciated!!

120 is the number of seconds that it will have to maintain 35.2 continually to be able to trigger and turn Port1 on.
If the value drops to 35.1 at any time, even if the countdown is at 119s, it will reset the timer.
It must have 35.2 or greater continuously to be able to trigger it.
Then it will run as long as salinity is equal or above 35.2.
It will stop and start the timer again when the salinity drops to 35.1 again.

I get it! Thanks! Although not sure how the port gets turned off when salinity drops to <35.2?

If I wanted to set so that the pump runs for x seconds when the salinity is 35.2 or higher or the salinity reaches 35ppt for y seconds - whichever comes first - how would I do this?

thanks!!

[rimai]

Can you explain y??
I don't follow.

[dazza1304]

Can you explain y??
I don't follow.

From looking at my salinity history, it seems that the salinity does bounce around a bit - maybe 0.2ppt.

So, ideally, when the salinity reaches 35.2, I would like to operate the ATO until the salinity reaches a steady 35.0ppt.

Turning the pump off after x seconds, is a failsafe in case something goes wrong with the salinity probe and the ATO gets constantly dumped into my tank - maybe I am better off using the float switch for this failsafe?

Is this how my code should look?

OK,

The above wasn't right and wouldn't compile, so think i have fixed as below.

All uploaded OK and controller runs, but when I disconnect salinity probe - simulating salinity greater than 35ppt (goes to 60ppt open circuit) nothing happens and I waited well over the 2 mins - port 5 just seems to be constantly off.

Any idea what I am doing wrong?

thanks..

Yes, it looks good.
When you remove the probe, it actually reports 6.0ppt
It's a display glitch that didn't erase the last digit when it went from readings greater than 10 to less than 10.

[dazza1304]

Hi Roberto - it works!!!

I will give it a try to control my ATO and see what happens!!

thanks again!!

[dazza1304]

Well, it works really well - thank you roberto!!

Now, to improve, how to I incorporate a float switch in the code to shut off the ATO pump in case something goes wrong with salinity probe to stop flooding?

thanks!!

[rimai]

Try this:

Code: Select all

 if (ReefAngel.HighATO.IsActive)
 {
   if (ReefAngel.Params.Salinity<350) lastLowSal=now();
   ReefAngel.Relay.Set(Port5,(now()-lastLowSal>120));
 }
 else
 {
   ReefAngel.Relay.Off(Port5);
 }
