2011 autosleeper control panel

Hi folks, just got me a 2011 flat floor symbol. The control panel ec51 has a line of rectangles on right hand side... think they are level displays. Nowhere can I find what each one is for... third one down - out of five- keeps flashing orange when I switch engine on. Anyone know what it means or indeed what the five lights in these rectangles mean. Manual doesn’t say. I have a solar panel, leisure battery. Real newbie to this but happy! thanks in advance.

I have the ec51. The verticals row of LEDs shows the level of power in each battery when you select the required battery by pressing the buttons on top row. If you press the water button the LEDs show the level of fresh water. When on hook up the battery level should show full by illuminating all the LEDs. When not in hook up, the normal level shown is all but the top led. Your handbook should give the approximate voltage of the LEDs lit. I've never had one flashing, perhaps that's a warning that the battery is low, it cuts off the battery when voltage falls below a certain amount, all shown in the handbook.
The instructions can be downloaded from here.....

I can't recall where I read this now, but I ~think~ that this simply means that the panel is in "EMC shutdown" mode - where all except a few of the habitation 12V circuits are turned off because the engine is running.

Edit: Now that I re-read the EC51 manual it seems that I remembered that wrong - the two "battery select" buttons are supposed to flash when in "EMC shutdown" mode - does yours do that when the engine is running with the EC51 powered on?

I’ll go down to the camper and see. Thanks for the help.

Just checking .. it seems to be ok now.

On our van the centre led of that column flashes all the time when the engine is running. It must be ok because all these functions work on our van.
