Progressive ems hw50c problem???

[dennis46c]

We just installed the EMS-HW50C on a 2008 Holiday Rambler Endeavor using a new Esco transfer switch and Intellitec 50 amp Smart Energy Management System. It is installed before the transfer switch. All wiring has been double-checked, the sensors on the correct wires and facing the correct direction and we believe the 50 power supply to be good in our storage unit (less than 2 years old). We tested the MH using an extension cord and everything was fine and the Intellitec EMS was properly light and no error codes on the HW50 display. We unplugged, pulled the MH into the storage unit and plugged in without the extension cord. This time, the transfer switch clicked on and then off, we received the PE-7 error code indicating line frequency high. We tried several times with and without the extension cord with the same results. I tried the bypass and it indicated OFF on the remote display but the Intellitec EMS lights did not come on indicating any service. However, we did have power to the microwave, the TVs came on although we couldn't get either A/C to turn on, not even the fans.

Question: If we bypass the EMS-HW50C, shouldn't we get full power as if we didn't even have the EMS-HW50C unit?

FYI, I forgot to turn the A/Cs off when I went back outside, turned the storage unit 50 amp breaker off for several minutes and turned the EMS bypass off. When I turned the 50 amp breaker back on, the A/Cs came on immediately although just the fans because of the A/C delay, and the EMS now seems to be working fine although I didn't test the bypass again. Does this make sense?

Thanks for your help!

My guess is you have low voltage or a problem in your storage unit. I'm puzzled by the frequency error code, but you problems didn't start until you plugged the coach into the storage unit. The wiring in the coach is fine.

There is no need to bypass the EMS since everything worked fine when plugged in initially.

Check the breaker for the coach AC management system, located in the AC power panel. If that is not tripped, I agree with RJay the problem is in the storage unit power.
Call Progressive Industries. The tech support is outstanding, but I don't think anything is wrong with the HW50C

Thanks guys, it looks like everything is working fine. No additional details right now becasue after 3 tries to post information, it says I'm not logged in so I've lost my responses.

The reason you had power to TVs and microwave was the inverter. When you plugged the coach back in and reset the circuit breakers with the air conditioners still on you put enough load on the service that the frequency fell into an acceptable parameter and you again had power. Just a glitch.

Thanks!!! I wondered about why the TV and microwave went on when the Intellitec monitor said no power coming in. Everything appears fine now and I figure it was just a hiccup while the new HW50C got "burned in". Thanks again for the replies!
