I am helping a local high school with their Unison system. I have also worked with a local dealer. The ssytem was installed over 3 years ago. during the last year and a half, the system has randomly turned on and off the circuits. The processor was sent to ETC to fix where they said it was working fine. I re-installed the processor and loaded the orignial program only to have the different zones turn on and off at random. I then disconnected one of the control panels and things seemed to stabalize. Two Days later, it was reported to me that the house lights were turning off after between ten and fifteen minutes. Then after another 10 inutes they turned on again. The system uses ETC Net to talk to the dimmers in conjunction with an Emphasis system. The Emphasis system was turned completly off when this started happening. Is there something in the processor that would send random signals to the house light dimmers?
Contact an authorized ETC dealer and arrange a factory loaner processor. Install that and see what happens.
If you continue to get issues, it's probably the config file. If the problems go away, then it's a CMEi processor that is going bad, despite what the factory says.
well i have one circut out of 160 that will flicker randomly for no aparent reason. we dont use it now as we are looking for some phisical reason for it's cause. our system is run by two unison prosessors that split the building, the one that runs the other half of the building is at home (etc) for a check up, a completely diferent reason but i tink i will send in this one to be checked and keep the loaner that i have for a bit longer.
point the bright end at the talent!
Lane, if you are only having a problem with one circuit, have you tried swapping dimmer modules? Doesn't sound like processor problem? Maybe it a ballast or wiring problem down the line?
Wolfey to comment on the earlier problem. Keep working with your dealer or the factory. Kinda sounds like they may have a button station that's gone bad. Or maybe it's in the config file, something got accidently recorded into a preset / look/ or button.

we have swaped the dimmer, and the cem for the rack. at this point the next thing is to do a swap of the processor and see if the problem shows its self.
You can also contact phone support at ETC and e-mail a copy of the configuration for them to review. I have also seen situations like this where the problem was a bad station or bad wiring. The wiring may have been just fine at one time but some change in the building has caused an issue. The most obvious example of this was when someone drove a screw through the station data wire, causing a short on the line. A station going bad can also cause this. How many stations are in your system?

12 that talk to that prosessor
this week i plan on putting a dmx teast unit in the line to see if there is a erant dmx signal on that chanel.
