Let me tell you how it works in > the UK, and > you will understand my incomprehension. We have all sorts of power configurations available in the US. The major difference between the US and the UK is that many items run on 110/120 volts. While, in the UK, you use two "hot" wires without a common to get your power, we often have a "common"/"neutral" that acts as one of the legs. Non-residential user generally have either 110/208 volts three phase or 120/240 volts single phase, depending on total power requirements. Keep in mind that these voltage values are approximate, not exact, and are often designated differently in different parts of the country. Residences are almost exclusively single phase. For the 120/240 system: If you connect across the two feeders, you get 240 volts. If you connect from a feeder to the common, then you get 120 volts. The voltage is in phase in both of the legs, even though there are two legs, which it is called single phase. Think of a center tapped transformer, where the two feeders are the ends of the turns and the center tap is the common connection. If you go from either end to the center, you get half the total voltage. Connect to the two ends and you get the full voltage. High power sites usually have three phase power available. Here, each leg is out of voltage phase with the others by 120 degrees. As a consequence, if you connect from a feeder to the common, you get 120 volts. If you connect across two feeders, you don't get 240 volts, you get 208 volts. For our dimmers at the theatre, we are on single phase. There are two hot leads plus a common. There is also an equipment ground. That is why Don stated there were three conductors plus a ground. There is an interesting consequence of our single phase power configuration. A person might note that the common conductor is no larger than either of the feeder conductors, and may even be smaller. Now, why would this be allowed, as intuition says that the current flow in the common would be the sum of the current flows in the two legs? The worst case is that all the current draw is on one leg, so the current flow is identical in that leg and the common conductor. If the current in both legs is perfectly balanced, then there is no current flow in the common conductor (think about the center tap configuration a bit). My 240 volt electric oven has only the two feeders plus an equipment ground. I would guess that this is the configuration used in the UK for everything. The same thing happens with three phase power. If the current in all three legs is balanced, then there is no current flow in the common. For some industrial systems (such as large motors), there is no common conductor - just the three feeders. I hope this helps. I know it can be confusing. Bill ------------------------------ Date: Fri, 29 Apr 2005 09:29:31 -0400 Subject: Re: Arbor Day! From: Bill Sapsis Message-ID: In-Reply-To: Dan.

If one of the clock signals is dropping out the packs might go into common mode signal detection giving you the symptoms described. You may have had a bad solder join for years and simply by updating your packs you moved the cable(s) in such a may as to give intermittent operation.

It isn't called two phase because there is no phase shift between the two feeders. There is a 180 degree phase difference between the two feeders relative to the neutral conductor. In two phase systems, the two legs were 90 degrees out of phase. It was also called "sine/cosine" power. I have never seen it, and doubt if it is used any more.

I did think of that, and checked all connections in the dimmer pack. I did not check the distribution panel, as the problem was only occuring on the one pack. When I get the chance, I will check the panel as well - but I will want someone else present since that will have to be done with the panel hot. I believe I mentioned that in one of my other posts - probably buried on all the other information.

If that were the case, you would expect the problem to occur with both packs. Or that the problem would switch packs when the link order was changed. Unfortunately, these are the old style packs with the TA4 type connectors. I have no idea how you get to the pin bases of the male connectors to resolder them. I suppose it would be possible to bore out the hole and replace the TA4F connectors with 4 pin XLRF connectors. But I don't want to do that if it can be avoided.

Unfortunately, with the theatre being a black box and with a history of directors and set designers wanting to do bizarre things, I can't count on any storage within the theatre proper - with the exception of things like lights and such that I can stash in the grid. My life would be much easier if I could say "Thou shalt use the theatre in a proscenium arrangement", but that's not the way it is :) Oh, well. The weirdness gives me the opportunity for creativity and problem solving, and that's why I'm in theatre in the first place. I foresee some serious cabinet making in my future, in the green room and in every corner I can find that I know won't cause grief in the future. -cdr ------------------------------ Message-ID: Date: Fri, 29 Apr 2005 10:38:33 -0400 From: Jonathan Wills Reply-To: Jonathan Wills Subject: Scissor Lift Hello all, I have a fun question for the masses.

In any event updating to 4pin xlr is a worth while effort if you plan on keeping the packs long term. Judging from what you did - upgrade AMX to DMX at the pack, my instinct tells me the issue is with the clock timing. Cheers Dale ------------------------------ Message-ID: Reply-To: From: "Michael S.

The grid height is about 12-14' and each bubble machine weighs about 5-7 lbs. Jonathan, Okay, so the kid's room has a grid? Is your client looking to adopt? It sounds like what you are looking for is a Pantograph. These are used in studio lighting and can be set with tension to be pulled down and repositioned and stay in the up position. Usually a pole pulls them up and down. They are designed for studio lighting and come in different lengths and weight ranges. I have seen them from DeSisti, Arri, Bogen/Manfrotto, but at the moment, I cannot find any info on those company's websites! Here is a link to B&H Photo in NYC that carries a lot of studio gear: http://www.bhphotovideo.com/bnh/controller/home?O=productlist&A=details&Q=&s ku=78572&is=REG There are a number of these units at B&H; this one is rated for "Loads of up to 26 lbs can be suspended using only the friction device, while loads up to a maximum of 40 lbs require the use of the optional springs. The pantograph can be adjusted to keep suspended loads from 2lbs to 10lbs perfectly balanced." Normally they have receivers on the top and bottom and you can clamp them to a pipe or other structure at the top (the Manfrotto one uses a rail system) and you can get/build an adaptor at the bottom with a tray to hold the machine. Some of these are used to do this with projectors. There are a variety of drop down hangers, but for those you have to go up and lock/unlock them, so you might as well just fill the machine in place! Good luck, Michael Eddy Eddy Marketing & Consulting ------------------------------ Message-ID: Date: Fri, 29 Apr 2005 11:44:08 -0400 From: Jonathan Wills Reply-To: Jonathan Wills Cc: mseddy2900 [at] hotmail.com Subject: Re: Scissor Lift In-Reply-To: References:
