I have inserted 3 extension cards on my expansion box linked to a profilux 3.1N ex: 1 PLM-CondS in the first slot, 1 PLM-pH-Temp in the second slot and 1 PLM-4Level in the third slot. I have connected 4 additional level sensors to PLM-4Level.

While Cond, pH and Temp work correctly, i didn’t manage to configure any additional level. I have tried to use each level sensor from imput 7 to 10, without any response. Now, I just use successfully the built in level sensor (imput 5) as auto top off in my sump.

Can anyone help me with the correct settings? How can I be sure that the PLM-4level card is correctly recognized by expansion box/profilux?

Thanks in advance!
