Hi,

I tried searching and reading all Tunze related posts but am still at a lost as how to set this up.

To make it simple, I am just trying to setup 1 Tunze 6100 pump with Random flow. I plugged the Tunze cable 1 to the L1L2 port on the back of the Profilux Plus II and the other end to the tunze driver box.

I then use the Profilux Control to setup 1-10V interface and set L1 to pump 1 and set from 3V to 8V. I also set 1 pump for group 1 in the Pumps section. Just to test, I set mode to No current and saved. I thought this would turn off the pump but after saving the pump is still on. Am I doing something wrong?

Thanks for the help! Attached is the control screen I have:
