I have been asked to troubleshoot a problem with a G.E. Lighting Control System. The client says that the lights worked fine one day and the next day the switches quit working, and are stuck in a mid position between On & Off. They've had two other Electrician's look at it in the past month with no solution, the lights in this office building have now been burning 24hrs a day for over a month.
I am not familiar with this G.E. system, but I did discover relatively quickly that one of two transformers that supply control voltage in the Control Panel was extremely hot compared to the one above it. My metered showed that this particular transformer had no output voltage on the secondary side. I ordered a replacement power supply and installed it figuring there was a really good chance this was the problem, since the switches use low-voltage for control.
The problem still persists!
Hoping someone here is familiar with this system and might be able to give me some advice.
Thank you.
