Issue with power loss and level sensor

[arking_mark]

I had a power loss and got unexpected behavior from a level sensor. I believe this behavior is incorrect and possibly harmful.

I have a level sensor for detecting low water. After a power outage (I've simulated this several times), the programmable logic associated with the level sensors fill status is triggered. At no time is the water low, in my case the water level will never change with a power outage.

Further analysis shows this happens with just the profilux losing power.

Disconnecting and reconnecting the sensors does not cause this to happen.

Please help.
