Light sensor gone haywire


I replaced a defunct dusk-to-dawn light sensor. The new one turns on all night, but during the day it goes on for a minute or so, then off for a minute or so throughout the day. Any advice?

Which type of photocell you have the twistlocker type or button type I will post the photo so you can see the differnce there.

Here one it called button photocell.




Here the other one it is a twistlocker type.



Both are not excat the same but very simaur what you are looking at and if you have the twistlocker type you may want to go to top of the luminaire and get either flat screwdriver or phillps screwdriver and loosen up a little then turn it either way to get the sensor at differnt direction so it can function properly.

And most photocell I know they generally pointed north direction for best operation but if you have any reflective surface you may want to adjust a little to avoid bright spot or dark spot.

For the button verison there is one surefire trick is make a plastique tube like a tunnel if won't shut off very easy but senice you have dark spot I don't know which type of luminaire you have few may have adjustable spots you can work on it.

Merci,
Marc

You have wired it up backwards.

Swap the black and red wires, and it should start behaving properly.

Try this one first.

That should take care of it.

If that don't slove it then you will have to replace it and when you hook up the new photocell the black is line side while the red is load side { that go to the luminarie } and white is netural connection.

Merci.
