I called the Progressive Industries 24hr, 365 day tech assistance number and left a brief description of the problem. Three and a half minutes later, I got a call back from them - pretty impressive.
2 days ago, I was drinking my morning cup when my power went off abruptly. This was just about daylight and after 30 minutes or so, I went out to investigate. I observed a few lights on but as it was early the state of the campground power was hard to determine.
I looked in the bay where my Progressive resides. The display was flashing all 8888. I had never seen that or seen it documented. I placed a call to Progressive and left a message. As I hung up from the call, the display changed to flashing an E4 code plus a voltage of 87 on L1 and 84 on L2.
As I waited for a call back, some other campers gathered in the street as campers do when issues arise. Some reported a "brown out" lighting condition and others reported A/C units that were struggling to run or were trying to start but couldn't.
I'm sure that those folks incurred some cumulative damage to their A/C that will shorten it's life.
I got a call back & after describing all conditions to the Progressive tech, he said the 8888 code indicated that the voltage was so low, typically in them85-90 range that the unit couldn't analyze. About this time an employee of the campground came by our little group and told us that a power line had been hit by a lift truck at the marina next door.
Very long story but the moral is, the Progressive protected my coach from any damage occurring from the bad power condition. The great tech support was added moral support.
Good power was restored about an hour later. Some unprotected folks had appliances struggling with damagingly low voltage for a total of nearly 2 hours. A year or two down the line, they will have a failure that they will not realize is directly related to this event & will tell folks that these EMS/Surge protectors are a waste of money.
