From what I understand the Smart EMS manages the power distribution. Every time we hook up to shore line 50 or 30 amp the board shows the AMP draw. We have been on the road for a week now. We made a couple of stops so far and the EMS was working just fine (with 50 AMP hook up showing the AMP draw). This time board lights up fine, showing 50 AMP service, all lights are green except it doesn't show the AMP draw as it always did before?
BTW dealer just replaced the new board. Anyone any idea or suggestions as to what is going here? Thanks

It's working fine now. It's not supposed to show amps on 50.

I am pretty sure it always did show the AMP. I just checked the instructions manual. On the the display panel shows 30 Amp mode when when shore power is first applied. The 30 Amp mode is the default theshold mode

That's odd. Here's a photo of mine. I have to select 30 or 20. It defaults to 50.

Ours shows amp draw when on 30 or genset but not on 50. Never has.

mine looks just like yours, except I notice yous is showing what is running. I am running refrig and 2 AC but is not showing in the status side. see pic.

Also the reason that I am sure it showed the amp draw, is because my wife notice the amp draw was fluctuating.

You might want to go see the dealer that just replaced the board. Something's not right. Do you have any circuit breakers turned off ? My EMS was not happy when I turned off a breaker for the W/D that I removed. Apparently there are certain breakers that cannot be turned off.

Ours never shows amps on 50 amp service. I thought it was defective and thought about taking it in, as our rig is just days from being a year old and out of warranty. I won't take it in now, as I really don't care on fifty amp as you have plenty to go around. And I can go out to the pole and read amps on our surge-voltage protector. This rig has been basically trouble free and had only one trip to the dealer for slide awnings to be tightened up as they flapped badly in high winds. All other small stuff fixed myself. I also do all lube and oil changes myself. Didn't want or need the extended warranty. The chassis has a 5 year 60K power train warranty anyway.

If 240 VAC 50 Amp exists between the L1 and L2 inputs, the energy management feature is disabled and all control relay contacts are closed, energizing all of the controlled loads. The Control Module sends a signal to the Display Module which causes the loadmeter to go blank, and all power status indicators to light.

From the Model 800 and 900 operator's manuals.

Sounds like its supposed to be blank when hooked up to 50 amp.

Nice system!

it works!!!
it shows the amp draw if you are running off the generator or connected to 30 amp line. I switched from shore line to generator, the display showed the amp draw..

Thank you, I am still learning.
