Has anyone ever worked with this controller? It is designed for Golf or large properties. I am dealing with 4 of these on a golf course. Recently the power stopped going through 2 of the controllers transformers, 120V in nothing out. This happened on almost the same day. The transformers have a reset button but it will not reset and doesn't appear to be tripped. These controllers are independent although they may share the same power supply. There were no storms or lightning strikes in the area lately. Any idea what may have went wrong with these? Is there anyway I can check the transformers to be sure they are good/bad? It is odd to me that the 2 went out at the same time.
