Hello everyone. I'm new here, and for some reason having a bit of a brain fart. My background is electrical, and I attended Pittsburg State University in Pittsburg Kansas. I received my associates degree in Electrical Technology. I graduated back in 2002.
So, now that I have my introduction complete, I'm for some odd reason stumped on a issue I was asked to look into at work. I don't know why, as I don't think its probably that hard, but, I'm having issues. If I need to I can probably draw up a diagram if it would help everyone out.
Here where I work all our lighting is 277v. Our outdoor lighting is split up between a contactor in a penthouse in the roof that controls "JUST" the roof lights, and then 2 contactors in the basement that control all the parking lot lighting, and exterior building lighting. Those two lighting contactors are side by side with a mechanical time clock in the middle of them that turns them on and off.
They would like that mechanical time clock removed, and a photocell installed in its place so that there is no more having to change the clock as the sunset/sunrise changes throughout the year. The roof contactor can stay on its time clock, as there is only roughly 10 lights that are on that.
So, after looking at that mechanical time clock and the two contactors I believe its 120v that operates the coil, and when it activates it sends the signal to each of the two lighting contactors to activate the outdoor lights.
I snapped a few pictures of what I'm dealing with, and hoping someone can point me in the right direction of how I would go about removing the time clock and putting a outdoor photocell in its place. I have room to run conduit from the exterior down to that area to get wires from the photocell, just confused on hooking it all up and making it work properly.
