the new programmable logic commands

My timer 5 is set to 12:00 AM to 8:00 AM, so i guess I would have to reserve that schedule for it to work?
 
Matthias,
I have a question about my dosing pump (water change, pumps 3 and 4) and ATO. I think that the ATO is coming on when the dosing pump is removing water, thereby messing with my salinity. Is there a way to schedule the dosing pumps to turn on at a certain time or a way to disable the ATO when the dosing pump is activated. I'm sure that I can control it with a programmable logic control, but I'm not exactly sure how to hook it up.
 
Hi Matthias,
Got everything but a problem arise from that setup,

Here is what my problem is.
When I am purging the water from 00:00 ti'll 4:00 the level obvioulsy drop below the sensor and since it's a programmable logic the top off doesn't occur, that is the predicted behavior I wanna to have happen. But the I didn't realize that the MAX on-time would still count. That being said when the AWC is done the my level is in a error state and needs be reset other that obvious, increase the max on-time which would defeat the purpose of having that fail-safe system in place. DO you have any suggestions on how to aviod that problem?
 
this is not so easy
the fastest workaround would be to disable the maximum time check - but then you loose some safety
-> next firmware version will have new level control operation modes, one of these modes will cover this
 
Ok, I've sat down with the ProfiluxControl to try and figure this out, but I'm having a hard time with it.

My ATO pump is Water 1 (S11)
My old water is Dosing Pump 4 (S4)
My new water is Dosing Pump 3 (S3)

Right now I have dosing pumps 3 and 4 come on for 4x per day at 1000 mL per time. This changes out ~ 1 gallon per day.

If I set a timer (Timer 3) up for S4 (12:00-12:30 AM, 6:00 - 6:30 AM, 12:00 - 12:30 PM and 6:00 - 6:30 PM). And do the same for S3, but shifter half an hr., what do I need to do for the programmable logic control?

Have Timer 3 be input 1 and Water 1 as input 2 with "AND" as the function?

Same thing for Timer 4 which would be S3?
 
Ok now that you have tried I will help you :)

I have everything under a timer, that is the best way to do this in my opinion....

Try or do the following.
Timer 1(or whatever you want) Discarting old
12:00 AM - 12:16 AM = 1000 ml
12:32 AM - 12:48 AM = 1000 ml
01:04 AM - 01:20 AM = 1000 ml
01:36 AM - 01:52 AM = 1000 ml

Timer 2 (or wahtever you want) new water
02:00 AM - 02:16 AM = 1000 ml
02:32 AM - 02:48 AM = 1000 ml
03:04 AM - 03:20 AM = 1000 ml
03:36 AM - 03:52 AM = 1000 ml

Now set the S4 to Timer 1
Now set the S3 to Timer 2

Also set your failsafe to atleast 4 hours.

Now for the programmable logic for the S11 (this will disable your ATO while the water change is occuring)

Configure timer 3 to the following
04:00 AM - 11:59 PM

Configure a new PRogrammable Logic 1 to

Timer 3
and
Water 1

After go to socket S11 and set it to programmable logic 1.

This should be covering everything about AWC and ATO.

Hopefully I covered it all......
 
Thanks Kidney.

Is your rate for your dosing pumps 60 mL/min? Mine is less than that and I believe that Matthias has said to give the pumps some time between dosings.

Is there a way to schedule a dosing pump to turn on for a specified time and dose a specified amount, because I would like to have it come on for 20 min but only dose 1000 mL. Make sense?

When you use the timer function, it pump to the max. which is the 60 ml per minutes.

That is why my schedule as a resting period between the pump .
12:00 AM - 12:16 AM = 1000 ml
12:32 AM - 12:48 AM = 1000 ml
There is 16 minutes between you have to let it rest the equivalent of the pumpin you have done. Therefor is has pump from 12:00 AM ti'll 12:16 AM and will start in 16 minutes @ 12:32 AM - 12:48 AM for another. So the resting is in the schedule.

Not sure I understand your question because the previous does exactly the with the timer, but just factor that it pumps 60 ml per minutes.

The problem that I have with that is that the pumps do not pump 60 mL/min. Mine pump at 40 and 46 mL/min due to the length of tubing that I have.

I guess I will try and figure out the times that it takes each pump to pump ~ 1000 mL and set up a time from there.

Thanks for your help.

NO mather what, don't make your pump run more than 15 minutes. just increase the amount of session of 15 minutes, just do an extra 16 minutes of pumping.

Thanks. I'll change it from 20 to 15.
 
Too bad we can’t just set a pump to pull out some water and then use the float/optical switch to stop the filling of the new water.

This way we could just use 2 maxi jet, use time to pull out the water and rely on the level for the fill, plus this way you would be sure that the ATO would not kick in if not enough water was put back for whatever reason.


hmm or would this? it's pretty much like setting up the ATO, I will have to give this a try. This would free up my pumps for dossing :)

I am pretty sure it can be done, I just don't have the hardware to test my theories on this.
 
can you clone a optical/float switch like you do for probes? that way we could use the same switch for both the ATO and water change.

I do have EX, I will play with this tonight
 
I don't think that you need the Ex upgrade for that, just the Level sensor splitter and another level sensor....
Basically you need 2 level sensor. Will look into the logisctic off it 2night when my kids are in bed......
