Author Topic: NC3240S-A white switch Abraham Robinson Film Handler Posts: 16 From: Oakland, California, USA Registered: Oct 2017 posted 03-30-2018 06:49 PM                    I've been reading old threads and have been warned by others about these failing (particularly on the NC-2000s); though it seems like not as much of an issue with the 3240? Then I was looking up images, and on the NEC website the 3240S-A has a black switch. Is this a replacement for the faulty white switch? or is it just a show-model difference that's only in the press photos. My venue has a 3240S-A with the white switch. Can someone give me an update? Thanks!  |  IP: Logged Peter Castle Expert Film Handler Posts: 220 From: Wollongong University, NSW ,Australia Registered: Oct 2003 posted 03-31-2018 05:07 AM                     We have a 3240 - not sure whether it has a white or a black switch - as I've never used it. I always turn the electronics on with the wall socket switch. Then there's no chance of that switch failing.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 03-31-2018 10:44 AM                     Its still a circuit breaker but just a different spec than the one on the NC-2000. As such, these breakers should not be used as switches and an external power switch should be installed and utilized.

And I am afraid that part of the problem is risen due to the documentation of NEC itself. A considerable number of manuals, facilitating the installer as much as the end-user was indicating those same circuit breakers as "Main Power Switch", even when there was a non-incorporated/external lamp power supply unit (LPSU) that had another, similarly designated "Main Power Switch". The "for the eyes of technical personnel only" powerpoint slides were also using the same expression, a (great) while ago. After all that, it is not an easy thing to restore the actual "Circuit Breaker" name and expected way of use over the "Main Power Switch" that for some reason slipped into the documentation. I've seen some odd translations from Japanese to English, that being very far from winning the award of the most puzzling.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 04-02-2018 12:51 PM                     quote: Ioannis Syrogiannis And I am afraid that part of the problem is risen due to the documentation of NEC itself. Yep! I went though about a dozen switches at a few different sites, but overall not that many as I installed 334 NEC's. I now have external switches on all of them which I installed on normal service rounds.

The way it's set up right now, leaving the white switch on and shutting off the main breaker triggers the UPS. Appreciate any suggestions you all have, the replacement part cost is absurd, and even more so considering it's just another one of the same cheap switches that are so easily prone to breaking.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 04-06-2018 11:22 AM                     The switch is expensive because it is German origin.
