Today I got the optical level sensor starter pack and a float sensor.  I am having a brain fart and can't seem to get it to work.  I have the 2 sensors plugged into a y adapter and the level sensor set to ATO 2 sensors,  but for some reason the sensor isn't turning on the outlet.  I also noticed the float sensor is setting it into instant alarm.  this is how I have it installed:
I've been using the contactless sensor for a couple years and it worked (when the sensor did anyway).  Just can't figure out whats wrong.  Any help would be appreciated.
