Applying >8V to the L-pin overrides the engine shutdown detection and activates the charger. This can be done, for example, with an ignition switch, CAN-bus engine running detector, etc.
To force enable/disable charging (i. e. turn the Orion XS on/off) without interference from the engine shutdown detection, a remote option as given in section Connection setup for remote on/off must be wired, and the engine shutdown detection must be switched off in VictronConnect, see figure below.
I tried wiring a switch between L & H, and connecting D+ to H; this did not work.
I feel like I’m missing something simple, please help!
I have now tried wiring a jumper between L & H, and a switch between D+ and H. This did not work, either. (With engine shutdown detection disabled.) As in this diagram:
Remove link/jumper then D+ straight to the H side should do the trick that will get it running the rest should run okay don’t think you need a physical switch unless a reason for that?
I ended up running the D+ signal to the H terminal, via a hard switch so we could disable the charger when necessary (like taking it to the dealer). This works.
The documentation is really unclear on these points!
