Yes, but I haven't figured out how to shrink my files small enough to attach them.
no diagram, but we used to do a pretty simple wiring set up.
Feed the photocell and clock motor with "Line" (and neutral)
(this often entails taking the motor lead off the contcat terminal)
Run the "load" of the photocell thru the clock contacts
and feed the contcator/light.
In this manner, the clock motor runs all the time. Set the time clock to come on early afternoon...contacts close but no power from photocell..once photocell closes..power flows thru already closed clock contacts. Set clock "off" for desired off time.
2nd scenerio using the clock as an "overide" is different.

You ever have dark cloudy days a simple timeclock can't account for?
I like to use an HOA with the timeclock/pc setup myself.
Wire ran as follows:
CB'er to Timeclock LINE
From Timeclock LINE through HAND contacts to contactor coil.
From Timeclock LOAD to PC LINE.
From PC LOAD through AUTO contacts to contactor coil.
Pretty straightforward install.

Do you want the photocell to override the clock to energize (bypass) or deenergize (interrupt) the clock's control?
Also, do you want a manual override as well, and to bypass or inerrupt, or both?

I need a more detailed answer. Try to answer my questions more directly. I'll rephrase them if you need me to.
I can make a perfect drawing for you if I can get the right answers. PM for my phone number if you'd rather talk.

If you have a fax number you can PM me and I will give you a quick sketch on how to wire it.

Okay, except you didn't mention whether yoy want the manual override to be on or off, so I'll guess a manual on. You can obviously just put a SP switch in line with the load for a manual off.
Presuming either your lighting is a 120v load, or will be running a contactor, here's what you do:
1. Run the supply hot to the 'line' terminal of the time-clock, so the clock stays energized so it keeps time.
2. Feed the 'load' of the time-clock to the 'line' terminal of the photocell, so it's in series with the timer and load.
3. Connect the lighting load or contactor coil conductor to the 'load' terminal of the photocell.
4. Obviously, connect the neutral (I know, I know) to the time-clock and photocell neutrals, as well as the load.
5. For the bypass, connect a SP switch as a bypass between the supply hot and the load terminal.
5a. If there's a concern about backfeeding the photocell, use a 3-way instead of the SP switch, like this:
5b. Connect the common terminal to the load, one traveler terminal to the hot, and the other traveler to the photocell's load terminal.
Let me know if you still need a diagram.

for cheap $ u can get a douglas 6 relay lighting relay panel that comes with an electronic timer and inputs for a photocell. then you can program it to operate however you please.
