Orion XS and Engine detection (with DELAY)

I done the switch from old Orion Smart Charger 30 A to Orion XS 50 A.
I activate the “Engine shutdown detection” switch … exactly the same as in the past (with parameter “Delayed start” set to 120sec.).
When I shutdown the engine the procedure works well … also when i start the engine … XS will start the charge … but it starts immediately and the DELAY wasn’t respected !!! I don’t remember if this happens also the first time I power-on the XS … but, in my navigations, it is normal that I stop / start the engine (I have a sailboat) … and the DELAY of the charging MUST BE RESPECTED ALL TIMES !!!
(note that I don’t power OFF the XS … it remains powered on … as it is connected always to the engine starting battery. It is powered OFF only when I leave the boat and go home).

What I do wrong ?!? And eventually why the DELAY isn’t respected ?!? What are the reasons ?!?
I’m quite sure the the older Orion Smart 30 A respect the delay all the times (both the first than the following starts).

Thanks

Make a screenshot of your settings.

The delay only applies to an input voltage between the “delayed start voltage” and the “start voltage”.
If the input voltage is above the “start voltage” the Orion will start immediately.

Ah … I was quite sure that in the old … the delay was respected always but if you say so … boh.
Now I’ve detached the old and I have the newer XS on board.
Attached the photo from the old settings of the “Rilevato arresto motore” page (excuse me but it is in italian) that I take this morning (from the 30 A, the older).

Thanks
