Q&A and troubleshooting

Is it possible to have a switch that when open will completely disable the Orion XS, and when closed will enable the Orion XS & engine shutdown detection mode? I’ve read the manual regarding this, but it’s somewhat confusing.

Only read 3.9 and ignore 3.10.

I have used the Victron SolidSwitch 104 with VE. Bus V2 to disconnect the Orion XS50 via the engine ignition circuit. I believe it is a low power draw relay. Below is how I wired SS104 Remote H - BMS Charge Disconnect
SS104 Load - Orion XS H terminal
SS104 Bat+ - Engine ignition on circuit
SS104 Bat- - Battery negative on Lynx

With this setup the BMS will control the Orion XS even with the ignition switched on. The current draw on the SolidSwitch 104 I’m assuming is less than that of Orion XS with power going to H terminal.
