Thompson The Weenie Man Posts: 4718 From: Mount Vernon WA USA Registered: Nov 2000 posted 09-10-2001 11:25 PM                     I know Japan's Line Frequency is 50hz, but I am not sure of the line voltage.  |  IP: Logged Don Sneed Master Film Handler Posts: 451 From: Texas City, TX, USA Registered: Aug 2001 posted 09-11-2001 12:10 AM                        Oh yea, the line voltage was check, in fact the console were ordered for Japan 50hz in one area & 60 hz in another, we have an exhast air flow meter to check the correct CFM, in fact Strong Techs came over twice to see if problem was in equipment, but it is okay....was told to switch to LTI bulbs, we did, problem is worst, only getting 500 hrs from bulbs, so we are thinking whoever making the insides of the xenon bulb may have a bad batch, (2) 9-screen theaters & both are having same problem, even strong scratching heads....it's one of those things that make you go...HUMMMMMM !! Our in the states jobs are having same problem.....just wondering if any of you guys are having problem with LTI, Osram bulbs with strong consoles ??  |  IP: Logged Dave Macaulay Film God Posts: 2321 From: Toronto, Canada Registered: Apr 2001 posted 09-11-2001 07:59 AM                     Power in Japan is either 50 or 60 Hz. Eastern Japan is 50 Hz (Tokyo, Kawasaki, Sapporo, Yokohoma, and Sendai); Western Japan is 60 Hz (Osaka, Kyoto, Nagoya, Hiroshima) with the dividing line between Osaka and Tokyo somewhere. I don't know why. Standard home power is 100V 3 phase (2 wire + ground). There is no neutral, and thus no higher voltage present as in USA power where the standard home service is 240V single phase + neutral, so it's a bit safer in that regard. This system surprised me on a Japan installation where we used an autotransformer to get 208V 3 phase power for imported equipment (simple ignorance again...). This is frigging dangerous as it gives a neutral about 120V above ground - and neutral is not switched in the North American switchgear we used. Ouch.  |  IP: Logged Jonathan Worthing Master Film Handler Posts: 384 From: Hereford, UK Registered: Apr 2001 posted 09-14-2001 05:21 AM                     Randy Did you take the voltage readings direct from the power supply & amps from the shunt. I have had the problem that the meter on the lamphouse was reading 20% lower than actual power. Just a thought.  |  IP: Logged Randy Stankey Film God Posts: 6539 From: Erie, Pennsylvania Registered: Jun 99 posted 09-14-2001 09:37 AM                     Y'Know, as I sit here in my room I'm thinking about different things I can go over next time I get to that theatre. (Hopefully over the weekend.) Thanks for reminding me about that one!  |  IP: Logged Pete Naples Phenomenal Film Handler Posts: 1565 From: Dunfermline, Scotland Registered: Feb 2001 posted 09-14-2001 01:35 PM                     Hence why I pay no attention to lamphouse / rectifier ammeters. I carry a Fluke clamp meter which will read up 600A AC or DC. You can then accurately check the lamp current, and by flicking the thing to AC, you can check the ripple current while you're at it.  |  IP: Logged Stan Gunn Expert Film Handler Posts: 176 From: Clematis, in the hills near Melbourne Australia Registered: Aug 2000 posted 09-14-2001 10:22 PM                        HiRandy Has the relay operation in the rectifier been checked? It can weld its contacts, or a componant failure can allow the relay to not open on strike,causeing high inrush current. Or a board track fail and then the capacitor is not in circuit causeing high ripple current. Just another thought from down under . ------------------ ALL PARTS FOR VICTOR AND KALART VICTOR 16MM PROJECTORS. SERVICE TO 35 AND 16MM PROJECTION EQUIPMENT.  |  IP: Logged Paul G. Thompson The Weenie Man Posts: 4718 From: Mount Vernon WA USA Registered: Nov 2000 posted 09-15-2001 10:36 PM                     I think it was a Chinese Xenon lamp that blew up in one of my lamphouses. It was a XQ-3000 watt lamp, no markings whatsoever. It let loose after 347 hours. Naturally, it ruined the mirror in the Super Lumex. It is from Q-Arc International, came with the installation of the booth. Anyone familiar with who made this particular lamp? Can I expect more failures like this? There is still one more of them in service - with the same amount of hours. Paul  |  IP: Logged Richard Fowler Film God Posts: 2392 From: Ft. Lauderdale, FL, USA Registered: Jun 2001 posted 09-16-2001 07:49 AM                     Q-Arc has been used in the U.S. for the past year. Harkins Theatres in Arizona is using them. They are suppose to be more reliable than LTI bulbs according to people I know but not definite until we finish with the current LTI test phase and the near future Q-Arc try-out.....still happily selling Perkins Elmer / Osram / Ushio.

They are close price wise as well. For lamp exhaust I always install an 980 cfm Grainger blower and have gotten great life from 2K and up lamps this way. Yes, it is more than most manufacturers reccommend but it has only helped things out as far as bulb life and thiings stay very cool.

The fan was cleaned out really well and given a few drops of oil and it's running pretty well, now. The "blades" were caked with crud and dust. Now that it's cleaned out it's running a lot better. There's a nice flow of air comming out of the tube at the foot of the lamp. They tell me that the thing is running a lot better now and the lamp seems to be behaving better too. Of course, time will tell. But I think the problem is going to be a lot better, if not cured. I took them a spare fan in case they need it. (It's a Dayton 4C446, FYI.)  |  IP: Logged Paul G. Thompson The Weenie Man Posts: 4718 From: Mount Vernon WA USA Registered: Nov 2000 posted 09-18-2001 12:54 AM                     Randy, I thought from day one it may be a air flow issue, especially when you mentioned the ends did "discolor". Thank you for the feedback. Paul  |  IP: Logged
