Thank you all for your replies, I have been switching off with the soft switch on the control panel and leaving the projector in stand by mode when not showing films. There seems to be a fan still running while in standby (it sounds like a fan anyway), is this normal? The noise makes one think the projector is more on than off if you know what I mean! It's definitely in standby mode though - constant orange light on top of the projector.  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!! Posts: 12814 From: Annapolis, MD Registered: Dec 1999 posted 11-23-2015 10:25 AM                     Ye olde "FAN 6" does indeed remain on. FAN 6 is the "AC ON" fan and will run whenever there is power to the projector, even in standby mode. I'm sure the thought is that there is some power to the card cage and thus some amount of air flow is to be retained so long as anything is on...even in standby. If you are looking at the front of the projector where the filters are (to the left of the lens), Fan 6 is the lower of the two fans behind those filters. The other fans that can be on are the LPS fans (lamp power supply).  |  IP: Logged Gronw Roberts Film Handler Posts: 60 From: Y Felinheli, Gwynedd, Wales Registered: Oct 2015 posted 11-23-2015 10:35 AM                     Great stuff, thanks Steve.  |  IP: Logged Gronw Roberts Film Handler Posts: 60 From: Y Felinheli, Gwynedd, Wales Registered: Oct 2015 posted 12-09-2015 04:05 PM                     Sorry to ask another question about this! Once the projector is in stand by mode is it safe to turn off AC at the wall straight away? The reason I ask this is because the projector still sounds like all the fans are still running (suggesting to me that it still needs cooling). If I leave it for about 20mins the fan will suddenly get much quieter. I've been waiting till that happens before turning off at the wall, is that necessary?  |  IP: Logged Justin Hamaker Film God Posts: 2253 From: Lakeport, CA USA Registered: Jan 2004 posted 12-09-2015 06:04 PM                        Once the projector is in stand by mode it is safe to switch it off at the wall. The projector does a 5 minute count down from the bulb off before going into stand by, which should be sufficient. But if you can give it an extra 10-15 minutes, all the better.  |  IP: Logged Gronw Roberts Film Handler Posts: 60 From: Y Felinheli, Gwynedd, Wales Registered: Oct 2015 posted 12-10-2015 11:03 AM                     Thanks Justin.  |  IP: Logged Carsten Kurz Film God Posts: 4340 From: Cologne, NRW, Germany Registered: Aug 2009 posted 12-10-2015 11:37 AM                     Gronw - I don't know how you organize your screenings or playlists - but it is possible to put a shutdown command at the end of a playlist. That way the projector is entering standby while you still farewell your patrons or clean up the auditorium. So when you get back to the booth, everything is done for the final switch-off. Same can be done for server shutdown, at least on a Doremi. - Carsten  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 12-10-2015 12:04 PM                     Another reason NOT to use those two breakers is because the white power on breaker has a bad habit of failing mechanically. That part is about $80 USD from NEC or 12 USD from an over seas source if you know where. I have installed external power switches on Many of my customer's NEC projectors because this switch ALWAYS breaks in the power off position. I have yet to have the two pole breaker fail but the single power switch on the NC-2000, NC-1200 and NC-900 are failure prone. The NC-900 switch is only sold as an assembly with the entire power PCB. It's quite expensive, but the switch is $9.00 from Digikey or Mouser.

I wonder why the switches are so fragile on such an expensive machine? quote: Carsten Kurz I don't know how you organize your screenings or playlists - but it is possible to put a shutdown command at the end of a playlist.

Is creating these commands hard? There's a macro creator on the Doremi but I wasn't shown how to use it. Shutting down from the playlist isn't really necessary here to be honest, there's a front of house team that deal with the public and clean up which leaves me free to be in the projection room to sort things out. Interesting to know that it's possible though.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 12-10-2015 03:01 PM                     I'm not sure why they used such a cheap breaker either. But then again circuit breakers are also not normally meant to be used as switches. There are switch rated breakers though. It's a German made switch, but except for the contacts is all made of cheap plastic. External switches solves that problem.

All the projection and sound was turned on and off via the breaker box on the wall. This continued until the late 80s when we had actual switches put in for the projection and sound systems. So those breakers have lasted the whole 39 years I've been there, with 10 years of daily on-and-off, and who knows how many years before that, without being replaced. They were in there when the place was built (1930) for all I know and they're all still there and working. Too bad NEC uses breakers that won't last more than a few months.  |  IP: Logged Steve Kraus Film God Posts: 4094 From: Chicago, IL, USA Registered: May 2000 posted 12-10-2015 09:57 PM                    NC1200C I have the electronics and lamp supply feeds separated. The electronics IEC cord plugs into a little switch/outlet thing I made on my stand and that plugs into the full conversion UPS. So after I shut down from the soft touch button and the bulb goes through the 5 minute cool-down (if it was not already off), and it goes to standby, I turn off that switch. I then kill the circuit for the lamp supply at the breaker panel when shutting down the rest of the booth equipment. If you accidentally turn off the breaker for the lamp before turning off the electronics, it gets angry and gives you an LPS failure warning. I would be glad to leave it in standby even if that means leaving the breaker for the LPS on but I don't see the point of leaving those fans grinding away using up their bearing life as well as air filter capacity. (I run a screening room so we are not cranking them out 12 hours a day.) I never touch the built-in breaker nor the white switch. In fact they are covered over. Standby mode means only a few things are still powered just like any electronic device with a remote has some bit of electronics active at all times awaiting your remote commend, also nearly any computer that starts from a soft touch button.* Good thing they don't need non stop fans for that! *I remember the early PC's where the main power control was a switch on the PS that emerged through the side of the case at the rear. My own first PC had a 120V toggle switch on the front that connected back to the PS.  |  IP: Logged
