Gas conduits will extract gasses regardless of the setting for the redstone control. For example when connected to a mekanisim electrolytic separator a gas conduit will continue to extract gas even when set to active with signal, and there is no signal.

System setup

Electrolytic separator gui

Gas conduit gui

Using EnderIO 2.3.0.421

Just a first check: Are you sure it is not the machine that is pushing the gas out? For most conduits the redstone mode only controls active pulling, not accepting/rejecting pushes (that'd be in/out/disabled mode).

I'm afraid I don't know, the separator does not have the same ability to be configured as many of the core mekanisim machines do. There's no automatic eject option, likely because the I/O sides are all fixed.

However I have had this issue with the gas storage tanks as well as the separator. I can't remember a specific instance with anything else offhand though.

Ok, I'll have a look at our code in the next days.

I had a look at it. The redstone checks are called correctly. For more I'll have to setup a debugging environment and trace it.

Well thanks for looking, at least its just a minor annoyance rather than build breaking.

The Electrolytic Separator automatically dumps gas to tanks/machines/pressurized tubes on either side of it. The gas tanks automatically output to the side that has the red mark on the front. This is just how Mekanism has set up its gas system.

Sure, I might try and see if i can use a autonomous activator with a wrench to control the gas flow. If anyone's interested in the result send me a message.

Thx VT-14, that was what I suspected. @Keyarose are you ok with me closing this ticket as it seems all is working as intended?
