Author Topic: Function of UPS on Barco projector Frederick Lanoy Film Handler Posts: 88 From: North of France Registered: Aug 2009 posted 08-29-2010 02:53 PM                     Hello everybody, I don't understand what is the function of the Uninterruptible Power Supply on Barco's projector. Barco user guide of DP 2K-20C doesn't help... Could anyone give me some explanations because it's really not clear for me. Is it really useful ? Thank you very much for your help.  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

That is, if you have a power blip...the lamp will go out but the electronics will remain running like nothing happened. If you program the Barco correctly (I believe under the "installation" menu), it will reignite the lamp once power is restored too.  |  IP: Logged Frederick Lanoy Film Handler Posts: 88 From: North of France Registered: Aug 2009 posted 08-29-2010 04:53 PM                     Thank you for your quick and clear answer steve !  |  IP: Logged Ian Freer Expert Film Handler Posts: 135 From: Wellington, New Zealand Registered: Oct 2003 posted 09-12-2010 04:54 PM                     Is this feature available on earlier version Barco's? i.e. DP100, DP1500 etc?  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!! Posts: 12814 From: Annapolis, MD Registered: Dec 1999 posted 09-12-2010 10:23 PM                     No, it started with the DP2K series...they have the AC for the electronics on a separate IEC connector. I think Christie beat everyone on this feature (UPS). Now it may be that the auto-reignite is possible on the earlier projectors with current software...I'm not sure.  |  IP: Logged Sam D.

Chavez Film God Posts: 2153 From: Martinez, CA USA Registered: Aug 2003 posted 09-13-2010 09:21 AM                       I definitely saw series one with UPS at 2009 trade shows in Hong Kong and Amsterdam. Maybe they never made it to cinemas but I'm pretty sure a few did. Does not really matter though except for purposes of debate.  |  IP: Logged Chase Taylor Expert Film Handler Posts: 175 From: Troy, Alabama, USA Registered: Mar 2001 posted 09-13-2010 02:45 PM                        I put in two DP-1200 in June 2009 that had it, but I never saw a 1500, or 2000 with it.  |  IP: Logged Joseph Pandolfi Expert Film Handler Posts: 213 From: Milford, CT. Registered: Nov 1999 posted 09-13-2010 08:34 PM                     To me I think it is a waste for the UPS supply to tie in with the Barco. and no the lamp will not relite after a power blip. I am totally against it having them in my DP100. First the UPS will run a self test every two weeks, so if a show is running strange things will happen with the video switcher and the doremi server. I had many calls to resume playback on a show that "paused" or 'no picture' because of the self test. So I do a manual self test on each of the units outside our showtimes (like 9 AM on a given day or right after a power blip). Still I have two units that still act up on it's own. Second, is the batteries, they last two years before they are replaced. If you ignore the warning (and the burning smell) these batteries will go dead and even on AC power the unit will not work at all to run the server and whatever is plugged in. Make sure you have a good power strip as a backup, you'll need it.  |  IP: Logged Carsten Kurz Film God Posts: 4340 From: Cologne, NRW, Germany Registered: Aug 2009 posted 09-14-2010 05:53 AM                     It true that in a lot of places, UPS cause more problems than they solve. If you do not already experience power drops once in a while during shows, it's simply better to just avoid them. The only drop outs my computer ever experienced was due to UPS issues, not power outages. - Carsten  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!! Posts: 12814 From: Annapolis, MD Registered: Dec 1999 posted 09-14-2010 09:36 AM                     It does depend on your power in the area...also the UPS' you have. Ours do not self-test randomly. And if they did...since they are sine wave out and have a zero transfer time...none are the wiser (including the equipment). The current Barcos will self-reignite the lamp too.

Make sure you have a good power strip as a backup, you'll need it. Well surprise Joseph, like any other hi-tech gear a UPS regardless of brand WILL need regular maintenance and checkups. If you have learned that the batteries only last two years, why aren't you scheduling replacements in advance? Batteries are cheap compared to lost shows and/or equipment damage from power issues, which any QUALITY UPS will prevent. (BTW, any vendor who puts a cheap UPS in such expensive gear as a DLP machine deserves a swift kick in the nads.) Again, those who think DLP is a "set it and forget it" proposition are seriously deluded. A "power strip" is not in any way shape or form a "backup" to anything. Regular maintenance would have prevented the issues you experienced.  |  IP: Logged System Notices Forum Watchdog / Soup Nazi Posts: 215 Registered: Apr 2004 posted 11-21-2012 07:11 PM                 It has been 799 days since the last post.  |  IP: Logged Barry Floyd Phenomenal Film Handler Posts: 1079 From: Lebanon, Tennessee, USA Registered: Mar 2000 posted 11-21-2012 07:11 PM                        Speaking of UPS back-up power... how big and how much does it need to power. We're putting in Barco DP2k-23B's with GDC SX2000A servers. What all should be hooked up to the UPS and what size UPS should I be looking at? I have a quote that includes a Tripplite Smart 1500 - but I have no idea if it's big enough to do the job.  |  IP: Logged
