Problem using Doser 2.1 SA in Slave mode as ATO

[johnamcdonald@gmail.com]

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.

Hello,

for better insight of your system and configuration, you can open a support-ticket and provide your Settings.par,
which you can create in GHL Control Center 'Backup and Restore' and attach it to this ticket:
https://www.aquariumcomputer.com/support/tickets-enquiries/

Please state there also, where the level sensors are installed and what you are intending to do, in order to understand the issue better.

Thank you. Unfortunately, when I attempted to back up the settings on my Profilux, I receive an error msg that the file doesn't exist. I can submit screen shots from gcc until I resolve the backup issue.

Photos of your current LEVEL settings will help us determine if any changes need to be made.
To which port are the sensors connected to?
