The Airlock Setup screen is where the pumps and silos are assigned to the appropriate airlocks via the green arrows. Any airlock, pump, or silo can be renamed to match any system drawings. Minimum pressure limits in PSI can also be assigned to each airlock/pump combination. One airlock can be assigned an airlock valve to allow a pump to be shared between multiple airlocks.
Pressing the set to defaults button will assign all the valves are momentary and set the default retract and extend states for each valve in the system based on Selina vortex valves. These setting can be changed manually if these types of valves are used. Valve names can also be changed to match any system drawings. Use the test buttons to test the outputs and inputs of each valve.
Assign the appropriate valves and valve positions to each silo/airlock combination based on your system drawings. Use the green arrows to cycle through each silo until all silos in the system are configured for each airlock.
