Title: ETC dimmers
Post by: O'Die on April 23, 2004, 05:45:31 PM

I have ETC L86 modules that will not work correctly with ANY drawer or SSR. This just started happening after a generator switch-over, but has been developing on other dimmers for awhile. They will smoothly run up to around 30%, then bump to full above 30%. In one case they bump up to full at 5%. Usually a new SSR has fixed this problem, but nothing we do seems to help. Tried new control module, resetting everything, etc...
Anyone have any ides?

If you have eliminated the control modules, SCRs, and controller issues, all that seems to be left is bad power. I have had other systems generate progressive malfunctions when bad power is applied along the neutral.  That is only a suggestion to look at, although you may have already done so.
