Dosing pump a logic programmable logic

**knibal** · 27.02.2017, 22:15

Hi. I have a profilux 3 ex and a dosing pump slave 1. all in the latest version. I would like the dosing pump to deliver the solution throughout the day except if it exceeds a value of conductivity that should not be paid.
For this I select dosing schedule below and automatically dosing times.
Then create a logic program (g10) as follows: input 1 dosing pump 1, input 2 conduct 1 increase and function And.
In the switch channels s25 I select progrmmable logic 10.
I understand that I should stop when I do not have to increase the conductivity but it is not so and continues to pay without stopping. what am I doing wrong? is this correct? Thank you

Is your slave doser connected to the P3 with a PAB? If so, why do you need to program a socket?

I have a similar issue. I run an ATO pump to dose with kalk only at night (keep pH higher). However, in case the ATO sticks "on" and raises the pH to 10 and kills everything, I want to diable ATO above pH 8.2. I did this:

Timer 1: on - 9:00 PM to 9:00 AM.

pH-value 1 set to 8.2

Progrmmable logic 1: (pH-value 1 increasing) and (Timer 1)

I tested by submersing the pH probe into pH 4 and then pH 9 solutions. It seemed to work lat night. It reduced the pH drop from 0.3 to 01.

I suggest testing your probe with fresh water and concentrated saltwater to be sure your logic works. On my 1st try, I got it all backwards! Glad I tested!

I've only had a P4 for a week, so I hope I'm trying help and learn at the same time.

Hope this helps.

This progamming example really helped me understand the logic: http://forum.aquariumcomputer.com/sh...lp-programming

Hello Bob. thanks for your help.
The dosing pump is not connected by pab is model one. Pumps are assigned to the sockes 25 onwards. The logical programming I see it correct as I have it programmed.
1. dosing pump 1
2.AND
3. conductivity increase

I want the pump to be dosed as long as the special timer indicates it, but do not do so if a conductivity value has been exceeded. But never stop paying. Just obey your timer. I think the dosing machines are a special timer or it is a bug of the profilux.

I didn't' realize the doser 1 was non-PAB.

Your programming look correct.

You may be right - a bug. I hope Matthias jumps in and helps you out.

Good luck, Bob
