[TowerTalk] Tower Lighting

[D Calder]

Not legal. You can't leave them on all the time. I'm assuming these are red
only incandescent at night
and this tower is painted red/white for daytime?

I have a shed full of red light controllers (Flash tech's) I would donate to
the cause to get one out of here.
Contact me offline at my email address. They can even be monitored remotely
as they have an eagle board in them
with Modem.

I have access to a 325' tower for my remote station, and like to assist the
tower owner where possible.

The tower lighting is controlled by a light sensistive switch working a
relay which actually controls the lights. The relay controller appears to be
home made and did have a large open frame relay in it - until the contacts
completely disappeared! (The actual load from the lights is about 1200w on
each of two phases.) I replaced the relay with a 30A contactor which I
thought was overkill and it was fine for several years, but that is now
getting unreliable. Clearly there is a pretty heavy switch on surge with
incandescent lamps, but this must be true at all tower sites.

What do the professionals do? (I suspect the answer to that is spend several
thousand dollars with Cutler-Hammer.....)
