control of 4 current pumps

[mistral]

I have Profilux 3ex serving a tank with 2 Tunze pumps on each side. I would like to switch on pumps on the left side simultaneously and then the two
both pumps on the right side (when the pumps on the left side are off). Duration of cycle 1-2 minutes.

Could somebody send me screenshot for this type of program, please?

Thank you for the help.

There are several different pump mode settings available - the best is to test them and look which suits you most,
it is often a question of testing until you find the best effect for you.

Dear Carolin,

I know that there are several pump mode settings, but i would like to set my 4 pumps as described in my post.
Could I have more detailed instructions, please?

Thanks in advance

You could try this:
Mode: Sequence 1
Duration: 1 or 2 minutes
Pump group 1: Pump 1 + 2
You can then define the pumps on the left side (in fact the 1-10V-interfaces where they are connected) as Current pump 1 and
the others as Current pump 2.

Dear Carolin,

I set the pumps as you told me, but it happens that all four pumps switch on together and then stop, and then work again. I don't know why.

Instead, if I use the sequence 1 mode and define separately the four pumps 1, 2, 3, 4 (without grouping the pumps of two side) only two pumps work alternately.

Can you help me?

Thanks a lot.

With sequence 1 the pumps are normally switched on one after another...

I propose to make the settings as I described and afterwards you post here the screenshots of your
pump settings and 1-10V-interfaces.

Here the screenshots of my pump settings.
Can you check if it is correct?

With this settings, the 4 pumps work all together sometimes.

I don't know why the currrent pump 3 appeares turned on in the screenshot. It could be only current pumps 1 (1+4) and 2 (2+3). Can you help me?

Thanks a lot!

Here my screenshots - perhaps you can make exactly the same settings for testing like me.
Because for me the pumps behave as you requested.

Thanks a lot, Carolin.
It seems to work with your settings.
