Actually, if you want to try it for a week or two to make sure you are happy with the setup, don't do anything but wrap a short piece of Artist's tape (3 inches or so) around the base of the douser shaft on the exterior of the projector while the douser is fully open. That will prevent it from falling and if you decide you don't like this option for some reason, all you will have to do is remove the tape and move those two wires back.Two things though... #1 What kind of automation and equipment package is this? #2 DO make sure you have your tech's permission before you do anything and be sure to label the two wires that you move (as well as anything else applicable) so if a new tech has to come in and do an emergency service call he will know what is going on. If you have the standard (and current) Christie package which I think you do, on the backside of the lamphouse there will be a terminal board. You will want to move the wire on terminal #6 (this may be labeled #6b) to terminal #13. Then you will want to move the wire on terminal #7 to terminal #12. The above paragraph will do the trick if you plan on removing the douser plates themselves, however if you want to leave them in, you will need to remove the wire going into terminal #8 and cap it off (and label it) with a wire nut or electrical tape. That wire will carry 110v through it once you power the system back up, so it can NOT be allowed to come into contact with anything. That will prevent power from getting to the douser and burning it up. Make sure you have the power off when you do this. That's all there is to it on that kind of setup, but do post specifically what equipment you have so the terminations can be verified just to make double sure...and I'll say it again, make sure you have permission.

Let's see here...3Q automation has a different breakout schedule and you are out of luck. There is no provision for an exciter on the 3Q automation...so you can't do it without what somewhat major modifications, which I wouldn't recommend.At this point your easiest option is to order the new Christie douser plates that have the circular indention in them. They won't melt like the older ones do. Alternatively, you could retrofit a Kelmar douser on there like is being discussed in another thread. Christie's part number for the new douser plates is 119263-002. Here is a picture of the BAD douser plate and what eventually happens to it...

The manufacturers of both projectors and the devices in question continue to refer to them as changeovers and surely they know as well as anyone that most go to single machine booths. It doesn't make sense to have two terms for the same thing and changeover has a good three-quarters of a century precendence. Booth beginners will find both changeover and douser to be alien terms requiring explanation so there's really little incentive to call it a douser especially when that term then has to be modified with "hand" or "electric."Besides, the MANUALS section calls them changeovers and surely you're not going to contradict Brad!

So if we follow Joe's naming convention, the exact same part should have two different names, depending upon the booth environment in which it is installed, correct? That seems a bit confusing for those of us who work in several different booths (some platter, some changeover, one with two machines plus platter). And, anyway, the name plate still says "Zipper Electric Changeover"...  For completeness, I'd be curious to know others' thoughts on how to refer to this part on machines which combine the functions of several different parts into one. For example, Kinoton projectors and Eiki 16mm machines don't have a separate hand douser--the changeover/electric douser is simply used for both functions and is beefier than a changeover/electric douser in a Century/Simplex type machine. On Cinemeccanica V5s, the changeover/electric douser also serves as a fire shutter (metal blade which drops down when projector RPM goes below a certain point). I'm sure that there are other examples of this as well. (Actually, Kinotons don't really need a hand douser, since the lamp only strikes when the motor is running, which is either a "feature" or a "design flaw" depending on one's point of view....)
