Opposite pump control...

[Tony@cambs]

Trying to get a nice wave from my 2x Tunze 6100 with my Profilux. I have pump group1 set to permanent, and group2 set to permanent opposite. 1 pump in each group, on opposite ends of my 5'x2'x2.5'. V4.0.1 Firm and soft.

I expected the pumps to do the exact opposite to each other, but I can see that even though the 2 groups have the same wave duration of 0.8s the groups are not staying in sync. This is seen in the wave and also in the software!

Any ideas, no way I can trne the tank frequency with it like this.

TIA,

I have experienced the same issue with the permanent and permanent opposite settings... the opposite is not quite opposite, the syncing of the pumps is off - within the groups as well as between the groups of pumps.

I have both set for perm opposite. Try that out.

Cheers guys.

Setting them both to perminant opposite does the same, the two channels do not stay in sync. I have now got a half way house - I set both pumps to circulation 1 in the 1-10v interfaces section so that they both run on the same channel. This is not exactly what I wanted as I wanted them pulsing on an opposite cycle.

Do I have a fault with my unit or is this normal? Which ever it is not right and I am not too happy about it.

Whats the v set at? Tunze's should be set at 3-10
I would double check all the settings and reffere to the manual.
Something is missing, I doubt its the controller. Good luck.

They are both set to 3-9 as I do not want to over load them, plus 10 would be too much wave.

This is not the issue though as I am talking about the pulse frequency and not the power. I have been through the manual and nothing looks wrong in the settings, but I can not see anything other than the pump group duration that should cause the channels to go out of sync

Put them in the same group

Yes ...put them in the same group. Works fine.
