Profilux Programmable Logic Usage & Examples

[d2mini]

Anyone have the instructions to connect ATO level sensor and turn on an outlet for a pump to run 30 sec pause and run again until level is reached?

I wanted to do the same thing. I had worked out a solution. However, yours is simpler and more elegant. I will use your solution.

Thanks Again, Bob

Bob and Ken, can you explain why you want it to pause?

Thank you

Not really a master but I have been working with GHL ProfiLux in a lot of installations of different purposes. I´m only glad if my 2 cents can help other people to use the full Power of ProfiLux.

I want to top off with kalk and only at night to keep pH more stable. I could ATO slowly with the doser, but I need to add 4 liters a night. I think it is too much wear and tear on the doser. I want to use a small pump instead. If the ATO is off all day, then the pump dumps 4 liters of kalk starting at 10:00 PM. The pH will spike way up. I could and will pump through a restriction to slow the addition. But that alone is imprecise. I want to deliver the kalk over 12 hours in spurts at about 5 or 10 or 20 minute intervals. I'll also use PL to stop the ATO should the pH hit an upper limit.

Hope that makes sense. If anyone has a better solution, please let me know.

Your welcome

Maybe there is better solutions - one of the strenght with GHL is its versatility

Sincerely Lasse

Lasse,

I found what may be a simpler solution. I can't test it since my level sensors have not arrived yet. I think you may be able to do it without PL.

It looks like if you uncheck "Always Active", you can activate directly through a timer. Does that look like it will work?

If you want to do that - I maybe have an other solution. first a question - do you use you pH probe in any regulation mode or is it only for monitoring? which ph is your upper limit?

That would probably work if you can set up a timer with intervals.

See there - I´m no GHL master Yes - your right - I have tested it - it works that way

Yes - You can

Sincerely Lasse

Right now, only monitoring. Once I get the level sensors, I would like to have the ATO no longer run above about 8.2 or 8.3. This is only to prevent all 20 gallons of kalk from getting dumped at once due to malfunction. I know how to do that with PL. But I would love to hear another one of your helpful solutions to simplify the operation!

If you do as I suggest in post 18 but after the Creation of PL G1 start with this

First create an other timer like this

​

Configure your pH controller. Here I think is good to use 2 way mode for the controller but if you want it very close to max - I´ll Think you can use variable pulse

​

Create a new PL G2

​

Create PL G3

Connect G3 to a socket

​

Voila. Now you have create a function that will pulse your pump if there is a demand for top off water but only if the time is between 22:00 to 10:00 and if the pH is below 8.25. You may not need the pulse - in tha case connect Fill water (ATO only) 1 and timer 2 as PL G1 and PL G1 plus pH increase as PL G2. After that - the socket shall respond to G2 instead.

Again, thanks Lasse!

That was close to what I planned. I had not planned to use the variable pulse. But the variable may smooth out the pH curve better than a fixed pulse. I'll try it both ways a few times and will report back. I just need my level sensors to arrive. Can you help me with that ?

[BCSreef]

Se there - I´m no GHL master Yes - your right - I have tested it - it works that way

Sincerely Lasse

Great, I'll try it when my sensors arrive!

I'm just like a monkey pushing every button in sight to see what happens! Spending more time with the P4 than the fish and corals. Not even sure if they are still alive.

Cool thread! I'll be checking it again once I set up my profilux.

Could someone help me in setting up my skimmer to stay off for X amount of time whenever the Powerbar loses power or the return pump is turned off by a feed timer. Not sure if this needs to be done with a Programmable logic or a different way. Coming from an Apex this would be called a Defer statement

On Power loss, go into the outlet and place a delay.
Programmable logic for "Defer", I'll send you a screenshot later.

Would anybody be interested if I created a guide to help people accomplish the more complex programming logic features? I've gotten pretty handy at it and feel I could write a decent guide so I can give back to the R2R community. If people are interested I'll make a guide and share some tips on how to really utilize the full extent of PL.

That sounds great Kyle.
