Cerbo GX relay 1 - Can't set Autostart functionality

Q&A and troubleshooting

Hi,

in my Victron system I have a Multiplus II and a Seplos battery. I would like to trigger the Cerbo GX relay 1 with battery’s SOC: it should be enabled only when the battery is below 20%, while it should be disabled all the time, even when the SOC is 100%.
Following the Cerbo manual, I configured the relay as shown in the image below.

It should be fine but now I have the problem that in the Settings → Devices → Genset the button stays fixed to Manual Start, and I can’t switch the Autostart functionality on.

I couldn’t find any further instructions in the Cerbo GX manual and I don’t know how to go on?
Thank you in advance for any suggestion.

P.S.: the relay 1 isn’t used for true Generator Autostart. I just need a relay driven by battery SOC.

@Enzo68 cant you simply slide the little slider across where is says autostart functionality?

Hi Trevor,

Thank you very much for your answer.

Actually the switch was locked, no way to turn it on.

As Gemini suggested, a reboot of the Cerbo GX did the trick.

Now it works as expected

Regards, Enzo

Edit: it is correct the Manual control stays in Manual Start state. It should be used to manually start the generator overriding the auto start/stop settings.
