the new programmable logic commands

[Tony Romano]

I was asking about placement of sensors in tank (or sump). Both at normal level?

 

[kidney514]

Level 1 is put at the level that your want to be maintained at and level 2 is put to lower that way the pump will pump untill that sensor is triggered, so therefor has to be lower!

That would be great. I just took delivery of my 4-outlet dosing pump and I'll be looking at automating my water change as well.

That procedure has nothing to do dosing pump, this done some regular pump, I don't recommend to use AWC with dosing pumps, you might burn your pump. If you want to do it with dosing pump, you have to do it with a schedule instead of the AWC, there is an example in this thread on page under my name.... DO NOT LET YOUR DOSING PUMP RUN MORE THAN 15 MINUTES at the time and it also has to rest the same amount time that is has pump.

Sorry Lorin, dosing pumps can be used happily, the 15 minute rule is a guideline. But you should not have to be utilising 15 minutes of time to do one water change really.

You are correct however about shedule or use it as switched

 

[kidney514]

To do my water change my dosing pump would have needed to run for 2 hours. In a large system, dosing pump may not be the proper tool for the job.

 

[AQD_ottawa]

It all depends on how much you are changing, if daily you should be changing very little, if weekly then yes it would take longer

 

[kidney514]

To do a 20% water change monthly on my system needed 2 gallons per day = 60 gallons per month.
60ml/minutes x 120 minutes = 7.2 liter which equal 1.92 gallons per day.

I have a propeller breeze that I would like to turn on whenever my temperature goes above the set threshold, but I would also like it to turn on from 11:00am to 5:00pm when my MH lights are on (to keep the lighting fixture cool. Can this be done?

I have the propeller breeze set as a chiller on Socket (3); set a timer from 11:00am to 5:00pm; and set aprogrammable logic - input 1 "timer 1" AND input 2 "chiller". Will this work? The previous examples have the socker set as programmable logic #1, but then the propeller breeze will not turn on when the temp rises.

Any thoughts?

 

[kidney514]

replace the AND by "or" when either one of those happens the fans will go on!

 

[Ken250]

Thanks... I should I figured that one out myself!

ok, not much of the above has made a lot of sense... I need to setup WC & ATO, my pumps are as follows:

For clarity the pumps are plugged into the following:

S2 - Pump(RO)
S3 - Pump(NSW)
S4 - Pump(Drain Tank)

I have 2 float levels setup with #1 above #2.

Now I need to set the level function to Water Cange & ATO and level 2 as not specified.

Ok, so if someone could tell me what each of the sockets should be set to:

S2 -
S3 -
S4 -

What logic do I need setup? Due to the amount i would pump out in a single go i would only do this once a week. (40L / 10.5 Gal)

And please explain what each logic set is doing.

Thankyou for you help.

Start from this post and follow it to the T and you will be set!

and then

after you have done that then set your socket to the following
S4 Level 2
S2 Programmable logic 1
S3 Programmable logic 2

Programmable logic 1 active your ATO with RO from 8:15 PM to 8:00 PM
Programmable Logic activate the same ATO but with the fresh salt water from 8:00 PM ti'll 8:15PM

i dont want timed events.. and thats not explaining it at all. i want the ro top off to be active at all times bar the wc period.

Hi my friend, Lorin is only trying to help.

If you cant find the instant answers here, please contact your Australian ProfiLux support specialist.

But I am sure Lorin will sort you out soon.

 

[sjp770]

Sorry for the shortness, but it is not easy to see what he means and thats why I asked for it to be explained. I had already read the previous posts which touch on the information I am looking for but they dont help me understand what each setting does. They also don't seem to apply to what I am trying to do (40gal once a week instead of daily).

Simple explanations like Matthias provided would be nice to have so I can see what setting does what.

 

[AQD_ottawa]

Hi

No problem at all,

I say this to everyone when seeking support, just keep in mind nobody is paid to provide this support here it is offered for free and most are just educated users. If you cant find the answer here you must always contact directly your local retailer or distributor. If you wish for one to one personal support this is often the best way.

Back to topic, I am sure you will get your answer shortly.

Ok, I tried setting it up the way that kidney514 said but when testing I had some anomolies. It drained for only a few mins (even though time overdue is set at 30mins) not enough to get to the second level meter. Then the RO came on for about 5 sec before turning off and then running the NSW for a min or so. Then as the level 1 was still not yet triggered (water back to normal) it started topping off with RO.

Also with your tutorials, there is no level 1 and level 2 in programmable logic, just water 1 and water 2, so im guessing thats what you meant.

This is how I reposted this on our local forum:

Turorial AWC part 1.


First you have to configure 2 timer one to start you water change, let work with 8:00 PM for this purpose.
Timer 1 will configure as follow in the lower right event start, and create a start time of 8:00 pm
Timer 2 configure normal event. from 8:15 pm ti'll 11:59 and another from 12:00am ti'll 8:00pm.

After all of that is done set Level 1 to "ATO & water change" and Level 2 not enabled. Also select in Automatic water change "is started by timer" 1, and also in ATO in general "is only active with Timer 2".

Got that so far, now lets move to programmble logic.

Part 2

Programmable logic
Programmable logic 1 will be the one that take care of the fresh water top off, and programmable logic 2 will be the one that take care of the actual water change.
So programmable logic 1 will be as follow "Water 1"and" Timer 2
and programmable logic 2 will be as follow "Water 1" and " Timer 2 [inverse] --> VERY IMPORTANT MUST SELECT INVERSE IN THE TIMER MENU.

Function -> setting for powerbar
----------------------------
Purge Pump = Level 2
NSW = Programable Logic 2
RO/DI = Programable Logic 1


Basically it is saying:
Timer 1 starts the WC @ 8PM
Timer 2 States the times the RODI is allowed to activate (leaving a 15min window for the WC)
Programmable Logic 1 is saying if the RODI is allowed to start (Timer 2) and it needs to, it will turn on the socket assigned to Logic 1.
Programmable Logic 2 is saying if the water needs topping up and it is not the time for the RODI to handle this then it will take on the refill job (Turning on the socket assigned to Logic 2.)

This means that if you manually start a water change during the RODI water allowed window (timer 2) then it wont work.

OK if you're nice to me, i'll help

It drained for only a few mins (even though time overdue is set at 30mins) not enough to get to the second level meter.

Sensor 2 is the one that has to be set with an overdue of 30min not sensor 1. I suspect that is your problem.

I strongly suggest that when you configure your overdue feature, that you stay next to the pump for the first time and check the time its requires and add about 1 minutes.

Let me know if that resolve the draining part.

PS Remember that the water change can only happend between 8:00 pm and 8:15 pm if you do a water change out off these hours it will be the RO/DI pump that will start.

2nd PS I have already put in a request to Matthias to have a new socket definition that will improve the AWC feature and make it more friendly it will be called something like "AWC Salt" and that will remove the need for timer use and programmable logic use also!

 

[sjp770]

It worked perfectly this time, I set it to run as it should instead of starting it manually. Because it wasn't during the RO period it only turned on the NSW. Sensor 1 & 2 were set to 30mins.

Thankyou for your help Kidney514.
