I have a Profilux 4 with two power bars and a Doser 2.1 SA set to slave mode. All are assigned to the Profilux. I want to use dosing pumps 2 & 3 as ATO. First, I assigned the ATO functions to sensors 1 and 2 respectively, assigned these to dosing pumps 2 and 3, and finally used two unused switch sockets (51 and 52) to the dosing pumps with sensors 1 and 2 respectively. Not clear to me if you can use a socket designation if there isn't a corresponding power bar assigned, but it seems you can.

I can run the dosing pumps manually, no problem. However the ATO sensors are not functioning, even though they did when I configured the Doser in stand alone mode.

I've followed the instructions on this video (https://www.youtube.com/watch?v=IxUfJJrcTXM) exactly, and checked the settings repeatedly. I have also powered off and on the doser and P4, and removed and reassigned the PAB devices. I've exhausted all the steps I can find.

Any thoughts on how to proceed, please share them. Thanks.
