What is the device that causes the delay with the coach accepting the AC power from the shore line? I have been using a Progressive Industries EMS-PT50C unit when hooking into shore power. There has always been a 3 minute or so delay before the power is accepted by the coach. Yesterday, when plugging into shore power, the coach would not accept the power. However, with out the Progressive unit, The coach accepted the power input. With the surge protector, all messages were acceptable with no faults. But after the 3 minute wait, I heard a 'click' noise from the PT50C unit, with no power to the coach. Any suggestions?
Thanks, Mike
Most Automatic Transfer Switches (ATS) have a time delay circuit built in. The actual delay will vary by manufacturer
Sounds like something is "sticking" in your primary ATS (the one that selects between "shore power" and "generator"). Why having the Progressive EMS--50 unit installed on your shore power line would make a difference, I don't know...
When you start your generator, does the coach power up normally (after the built-in ATS delay)?
GO TO THE PROGRESSIVE INDUSTRIES SITE AND READ UP ON YOUR MODEL,I just did and it has a built in delay of 136 seconds.
As I said, with the Progressive unit, the coach gets no power, regardless of a time delay.
Check the voltage output at the female socket on the EMS-50, after you hear the "CLICK". Perhaps the internal switching circuitry on the EMS-50 has malfunctioned?
Call or email Progressive tech support? Progressive Industries RV Surge and Electrical Protection industry lea (http://www.progressiveindustries.net/ems-pt50c)
We have the same exterior model (pedestal mount). Yes, there is a delay (fooled me a couple of times), but "the click" should indicate the EMS is switching power. A draw-back to the portable is it's hard to read the testing sequence if the light is wrong.
Those are great devices (pricey, also), so problems are few, usually. I see from their website they are closed for the holidays, but a call to tech support might get through. Let us know what you find out, good luck! 919.267.6975
Thanks, I will that a try.

Found this discussion about a failed EMS-50. This was a hard-wired built-in unit, so may not be applicable to your portable model.

What I just noticed in my book, is the EMS should give you a code# at the end of the test. Even if the EMS itself is bad, it will give a code. It seems the code #s will not show once the unit is disconnected. I'd plug it back in, get a chair and watch it do it's test. Have a slip of paper to write down the code #. Any error code other than "E O" or "E 10" is suspect. 2 min 16 second delay.
Is there another coach anywhere to try it on? would tell you if its the protector or the coach,if it does the same thing on another coach its the protector.What is the voltage going to the coach,I think that model has the low/hi voltage shutoff.
Is this a pedestal that you have been using? Was the pedestal checked for proper voltage? Just a guess on my part as I do not own this product
The EMS-PT50C has that feature: "E 5" is high line voltage above 132v on Line 2 and "E 6" is low voltage below 104v on Line 2. E 3 & E 4 are the same for Line 1.
Right now I am in the shop having all airbags replaced Will be back home to my shore power in an hour or so Error code was E-0, which is normal

Something is wrong, here, and should not be ignored. When you got the E-0, was the coach still plugged into the EMS & power?
