I want to use only the sensor unit of the PR511, to turn on a light (using its secoundary light turning on capibility) that is already working with x10 switches. It seems to work OK with a load between the blue and white wires. (I used a pigtail and bulb on a temporary basis). Am I able to directly connect the blue wire to the white wire in order to bipass the primary function of the sensor, or must there be a load between them to prevent damage.?

Do NOT connect the blue wire to the white wire. If I remember correctly... the blue wire goes to the light bulb(s) along with a white wire (actually I checked the online manual). Those wires are powered when motion (or dusk) is detected. Without a load (light) wiring them together would be a dead short.
If you're not going to be using a light.... cap the blue wire with a wire nut. Then cap the extra white wire with a separate wire nut.Then use electrical tape on each wire nut to be extra sure the wire nuts stay secure.
I've never used the floodlight (PR511) "wired" without a bulb. But I have had a bulb burn out. And the sensor functioned fine without a light. I added a modified image that shows the blue and white wires (separate with wire nuts). If you don't feel comfortable and knowledgeable with wiring... get a more experienced friend to give you a hand.

Excellent, all now works fine. I had not run into the house to look fast enough to see that the sensor WAS working without the blue and white connected.

Thank you for the reply. Sometimes we don't get replies to the simple one post answers. It's always nice to know things worked out well. I use and really like those PR511's. Just don't point them into the sun and they will serve you well for many years.
