What is the rotate at distance. Is that from another mod? If that is from remote-configuration, there are some incompatibilities. The author of that mod had mentioned adding an opt out call, but it doesn't exist yet. The alternaive is marking it incompatible, but the the two mods couldn't be used in the same game.
No, you wouldn't wan't to use the on/off capabilities of the combinator. As I have mentioned in the other thread you started, turning the combinator "Off" means NO signals will be sent in to the station. No train limits, no train lenght limits, no network id, etc... Your requester with 100K of ore on hand now become a provider because you are not sending in a high provide threshold.
In order to tell LTN not to generate deliveries for a station a high request/provide threshold needs to be sent in to the LTN input. Therfore the LTN Combinator needs to be ON.
