So I just set everything up and an odd thing is happening.
I turn on the swg, and pump is running off of the same outlet as it has for years, set the hours and wait for the green light to appear. A few moments later the green light appears as it normally does and almost instantly the screen goes blank and the unit shuts off. The pump continues. I unplug the swg from the extension chord and the unit starts up again but the same process repeats.
I can confirm that it is not the breaker tripping.
Any thoughts? Thanks!
