Author Topic: ORC 1600 Lamhouse Sparkgap and PS Wiring Cody Martin Expert Film Handler Posts: 214 From: Edinburgh, IN, USA Registered: Jun 2004 posted 05-09-2007 08:21 AM                        Hi guys, Have a few questions on my new ORC1600 lamphouse and power supply. First one is, is the sparkgap under the reflector suppose to have something around it? It looks like it may have been in glass..but I'm not seeing any sign of that in the lamp house. Is it okay to run without the envelope? See attached picture. The second question is about the power supply wiring. I'm planning on running the ps on 220 so I assume that you hook one leg to each of the 220 lugs. What about the 3rd ground wire as I'm not seeing a terminal for that? The last question is about the fan relay block in the power supply. The wires are just sitting around it...does anyone have a picture that they could check to see if they are supposed to be hooked up or not? Thanks for your help, it's veery appreciated.

He's an old ORC guy. He can answer you questions.

Substitution may work on electrical parts, including spark gaps.

That's what I was fearing about the part. I did find the other part of the envelope. I just didn't know if the gap was in a vacuum or could be used without one. If it doesn't have to be in a vacuum i could put the piece of glass back around it and use it until I can find one. Louis, might you have in your stock?

The covering is just to keep the electrodes from getting into trouble.  |  IP: Logged Phil Ranucci Expert Film Handler Posts: 236 From: Carpinteria,CA, United States Registered: May 2006 posted 05-09-2007 11:46 PM                     I'm about to toss out a bunch of ORC 2K rectifiers and platters. Let me know what you need and I'll see if I can remove it.  |  IP: Logged Richard Fowler Film God Posts: 2392 From: Ft.

The cover is an insulated cap not under vaccum. The rental ORC units I had and for client repair I have used a conventional "tube type" spark gap as used in older Cinemeccanica and on the typical German Bauch ignitor.  |  IP: Logged Tim Reed Better Projection Pays Posts: 5246 From: Northampton, PA Registered: Sep 1999 posted 05-10-2007 01:41 PM                       quote: Richard Fowler The ignitor is a Victoreen which is a division of a resistor manufacturer.... and on the typical German Bauch ignitor.

I'm going to put the glass casing back over it and position it so it stays on there. I believe it was cracked and shipping just knocked it off. Anyone have a manual for the rectifier so I can get it hooked up? Thanks, Cody  |  IP: Logged Cody Martin Expert Film Handler Posts: 214 From: Edinburgh, IN, USA Registered: Jun 2004 posted 05-12-2007 04:24 PM                        Just wanted to ask one last question, for now. I have the 4 terminals in the power supply labeled 115v 115v input and 230 230 input. I do not see a neutral or a ground. Any ideas how to go about hooking these up? I can get a picture if needed. Thanks, Cody  |  IP: Logged Matt Zeiner Expert Film Handler Posts: 146 From: Windsor, CT USA Registered: Sep 2003 posted 05-14-2007 08:40 PM                     I'm pretty sure ground goes to chassis somewhere in there - look for a lug. I recently got replacement RF transformers for those ignitors from Strong, and regularly use the sparkgaps from discarded Strong DC ignitor PC boards to replace faulty ones in the ORCs... Since you are going to run on 230V, just make sure the chassis is grounded - you'll be fine. If 110, one of those terminals marked 115 should have a white wire on it. Neutral.
