Hymer Help PLEASE

[Razamataz]

Good morning one and All.
after checking all my fuses all seem to be okay.!!But!! I am now getting a funny read out on my controller.
usually it reads 128 ah and shows solar.
Because I was footering about I obviously disconnected the batteries and now can’t get proper read out!!
Can anybody help???

DT201 display panel - set up codes.

This shows how to set up the panel depending on the features of your moho.

www.motorhomefun.co.uk

In the resources section on blue banner at top of the page, you may have to scroll to the right.
Motorhome technical manuals, page 2, near bottom is the dt201 manual, or use link above.
Hopefully of some help.

 

[Razamataz]

Yep I have used the very same manuals
right at the Very bottom it says Don’t press ok
guess what???? I did

Try unplugging the readout supply. Wait a few seconds before reconnecting.

Your picture shows 55% and ?

Dt201 manual, section 3.6.1.
Shows alarm as battery display plus ?

Remedy given is to fully charge the battery.

Perhaps worth a try leaving on mains charger for 24 hours.

In Spain at the moment!!only got that big beautiful sun to supply!!
The batteries were and Are fully charged according to my multI meter .
The controller read yesterday before I removed the fuse 128ah!!..perfect!!
I removed fuse and reinstalled…now the controller says what it says
But is taking a charge of 2.3 ah …. Now says 59ah

I think the application of mains somehow does a reset by charging at a higher rate than solar. But that is my guess and may not be correct.

In the settings it gives you the option of putting in the Ah of the batteries. I suspect that by disconnecting them you have reset it to the default of 90Ah?
The other thing, as mentioned above by SandraL , is that the state of charge is an estimate and the system needs to recharge a couple of times to gain accuracy

 

[Razamataz]

Thanks
so the consensus is???
disconect
reset
recharge

Im not sure if you need to disconnect, just reset and charge a few times

Like most chip controlled units once they start giving incorrect information they won't stop until ALL current is discharged. I assumed that maybe everything is working as it should therefore just the display needs to correct itself. So I suggest if nothing else works make sure the controller is completely isolated for a few seconds or minutes maybe that will work.

Maybe you have lost the setting for the battery capacity. You can check this, and correct it if necessary. Press the 'Menue' button, might need a long press of a few seconds. When in the menu, scroll to the battery 'nom' setting (Nominal, not the 'max' setting which is different)

The battery Nominal capacity should be as on the battery label. Perhaps 160Ah. The panel then calculates 80% of that, ie 128Ah, and that is displayed as the 'max' capacity, so that it never goes below 20%, a sensible choice for Gel batteries. When the display is reading 0%, there is still 20% charge in the battery.

To exit the menu, just leave it alone, it will exit automatically after a time. Or press one of the buttons on the left.
