Hi,
until this morning everything worked fine. But today I noticed that the yellow light of my 2nd powerbar was off; indicating no connection with the profilux.
I switched-off the power bar / the profilux ... nothing changed.
The connection with the 1st powerbar or the dosing pump unit is ok.
The 2nd powerbar is chained on the 1st powerbar.
If someone has an idea of what's going wrong, or some points to check...

The last but not the least the shop where I bought it is closed. It's a good day today :-)

Thank you for your help.

If you need more details don't hesitate

regards
