It's been a long time since I had anything to do with a mechanical timer, so my memory is sketchy on them. I'm talking the kind of timer that has a 24 hr dial that you place small 'dogs' on that trip the mechanical part of the switch turning the pump off and on. You wire a supply voltage to it and then run either a single leg for 110v or two legs for a 220v pump, or light, or valve.
There is also an 'master' switch that can be used to turn the pump off and on. These controls have been around forever and are made by Dayton, Intermatic, etc.
I want to use one to control a misting system I am building in my green house. I have a box of them I bought from a shop that did handy man work and was getting out of the irrigation business, (I bought all their PVC pipe and fitting, and all their plumbing tools, so I have no reason to think they lied to me when they told me these were working controls, either new, used or repaired.
They are all mechanical, and simple, except for the time motor which is either a 110v AC or 220v AC motor depending on whether the switch itself, is a 110v or 220v controller.
Here's my question. If I hook up the correct voltage to the appropriate terminals, as if I was wiring in the pump, shouldn't the timing motor engage?
It seems to me that's all I would need to do to test one of these dang things, but I have put voltage to all of them and NOTHING. I've double-checked my voltage and connections - it seems I'm doing this correctly. Two of them are obviously brand new, and were still in the Dayton box, thought the box was open.
It doesn't make sense to me, I have all kinds of electric motors stored away, and they just don't die from dis-use.
Any old timers out there who have some experience with these things?
Thanks,
GeoD
