EDIT - turns out the HW50C was not faulty... it was (ahem) the installer (me). See updated post below with pics.
Greetings all.
Bottom Line Up Front - I think I got a faulty EMS unit...
So... I recently installed a hard-wired Progressive EMS and yesterday was first chance to test it. Fired up good, no errors, all is good - except it wasn't.
Took me a while to realize it, but only half of my panel was live.
Check the remote display unit it says all is well: L-1 125V 0A 60Hz, L-2 125V 0A 60Hz, E-0 (there were no A/C loads at the time).
But strange - the EMS display says L2 has power. Quick check of all breakers - everything is good. OK, time for the multi-meter...
I pull off the breaker panel cover to access the A/C wiring and get out the Fluke:
Readings: L1 to Neutral: 125V, L2 to Neutral: 0V
huh. Must be a faulty connection in the EMS itself I think.
Okay, remove the lid to the EMS and crawl around and contort myself to get the following:
All connections seem good.
Readings:
Line In:
L1 to Neutral: 125V
L2 to Neutral: 125V
Line Out:
L1 to Neutral: 125V
L2 to Neutral: 0V
So for some reason, the EMS is not passing through L2.
There were no errors showing on the EMS display, but I tried the EMS bypass switch. Same results.
When I first discovered this, it was at home on a 50A to Household adaptor. I know the adaptor is good (or always has been) and I am reading 125V on both legs on the line in side. But... maybe something weird going on.
Tried it again when we arrived at our 50A site. Same result.
So I spent the first 60 minutes after our arrival "un-installing" the EMS and re-routing the OEM cable back to its original position and connections in the breaker panel. NOTE - REALLY glad I didn't cut the OEM power cable to install this.
Question for the group here - anyone else experience something like this? Anything else I should try? Or do you think I just got a faulty EMS unit?
I have not yet contacted Progressive yet - just confirmed the issue yesterday. The owner's manual (all 4 pages of it) is no help.
Cheers and thanks!
