ProfiLux Plus II problem with level senors...

[PEA]

Recently got a ProfiLux Plus II with firmware 4.08 and running ProfiLuxControl II, Version 4.0.8.1 on the PC and I can't get the level senors to work. I have a float sensor and an optical sensor for my sump to detect low water level and have the pump for my ATO run and fill it to the right level. But I can't get either sensor to change states when plugged in. In the level diagnostics all I get is an "X" won't change to a different state no mater what I do to the sensor. Same problem if I plug them in or with a splitter and use both. What could be the problem? Is both my sensors broken? Or is there something wrong with my level port on my ProfiLux Plus II?


Thanks!
