My current pumps arent alternating... Any suggestions ???

[badazztealcobra]

I just know that im overlooking something basic and its going to be something easy.... For some reason my Tunze 6101's arent alternating when I have them set on permanent opposite. I have them set at 60% currently,

so the display says (Pu. 1&2 0% 60%) and neither pump runs. when it switches to (Pu. 1&2 60% 0%) both of the pumps run.

Im trying to have the left one run for 20 seconds, stop, right one run for 20 seconds, stop, left one run 20 seconds, etc......

Both pumps are plugged into a tunze splitter and then into L1/L2

What am I overlooking ???

Thanks guys....

Are you sure you have a Tunze1 and Tunze2 cable? Sounds to me like you have 2 Tunze1 cables

The bags said it was the two different cables when I ordered them from Todd.... Any way to tell other than the packaging ???

Just uploaded to 4.02 and its still doing the same thing....

Did I get the wrong cable and just not notice it before ?!?!?

Can I plug them into different "L" ports and get them to alternate ??? I tried flip flopping the wires and that didnt make any difference....

I could've sworn they were alternating before and now theyre just pushing water right into each other and not making it all the way across the tank...

did you set the 1-10V interface function L1 to pump 1 and L2 to pump 2?

Of course not.... I knew I was having a stupidity moment and missed something basic...

Thanks as usual Matthias. :thumbsup:
