Looking for some help...

I just switched to the ATO set-up with my dosing pumps for freshwater additions. Everything has been working well for about a week. Occasionally, the ATO disconnects from the main unit. Meaning, the computer stops recognizing the ATO. Once I reset the computer, then everything works well again. The plug is tight and dry into the computer.

I am using the Profilux II plus with the mechanical float set-up.

Why does the computer loose the signal occasionally? any thoughts?
