AWC Weirdness

[Travisr100]

I have my AWC set to run three times each day starting at 9 AM. For the past few days it’s been running fine. The AWC will run and change the water and then after that the ATO will run as necessary to top off until the next AWC. That’s all as expected.

This morning, however, at 9 AM the AWC ran as expected, but then after that instead of the ATO pump, running to top off water as necessary the AWC filll pump is turning on instead of the ATO in order to top off the tank

Has anyone ever seen anything like this? I went into the status page and turned on the fill pump for a minute and set it back to auto hoping this will reset it. Will just have to wait and see.

See below the screenshots where everything was running fine yesterday compared to today.

I will add that on my AWC settings the fill pump is set to a max run time of 22 minutes. It looks like it hit that max run time for some reason which is odd. It usually only takes 12 minutes or so. However the level in the sump currently is clearly at the top sensor. And the fill keeps turning on to top it up instead of the ATO pump.

For several minutes after an AWC completes it will use the fill pump for top off. Mine has always done that.

Mine is doing the same thing untill i do a reboot of the collective. I have a end time set up in the schedule im not sure why its still doing it.

For a given time after the high level sensor turns wet and the fill pump turns off it will do any ATO using the fill pump instead of the ATO until that time has expired. It has nothing to do with the schedule time.

What is that given time before it switches back?

So what does the end time do? does that set when they are supposed to stop running?

is there a way to set interval of when it does a change so one runs early am and one runs late afternoon?

I am not sure the exact time it last but I think it is around 30 minutes. I have mine set to do 4 water changes a day. Here is a screenshot of my schedule. I use an external schedule setup in schedules.

There are scenarios where fill may run multiple times. Pretty sure there is logic built-in to continue repeat fill if the sensor becomes dry within a short duration of fill completion. So it could possibly have been normal behavior. BUT to see it repeatedly run THAT MANY TIMES is highly suspect. Is there any chance you saltwater reservoir was low? Stumped to come up with other possibilities as the optical sensor would fail wet, triple optical sensor would fail unknown. Did your ATO eventually run sometime after 29 Nov 09:56:30?

No, salt tank was definitely not low. I haven't seen this behavior again here lately. I'm keeping an eye on it though.

I spoke to hydros about this, when awc is running and is filling back up it will fill to the second or top line of the optical sensor, and it looks for it to be steady there for 5 minutes then it switches back to ato, so where i have my optical sensors its some turblent water near where my reactors and skimmer are, It was suggested move the sensor so im going to move it into the return area so its smoother and see how it goes.

I also set the minimum run time on my fill pump to match my minimum on time on my ATO but both pumps are dosing pumps at 55ml a minute flow rate.

@BluJ thanks for that info from Hydros. Helps with the understanding.
