Guide (Airlock) Atmosphere to Vacuum
From Unofficial Stationeers Wiki
Description
An Atmosphere to Vacuum Airlock is a Room that can evacuate and refill its internal volume with the Atmosphere connected to it. It has two or more airtight Portals which all do not open simultaneously. An Atmosphere to Vacuum Airlock allows passage between a vacuum and a pressurized environment without the loss of Pressure.
An Atmosphere to Atmosphere Vacuum Airlock can be controlled automatically using a Circuitboard (Airlock) installed within a Console which will refer to the pressurized environment as "interior" and the vacuum environment as "exterior".
When activated with the interior-portal open, the system will automatically close the interior-portal and will activate all selected [[Active Vent]s to try to evacuate the interior-atmosphere from the airlock chamber. Only after a total vacuum is achieved within all of the Large Grid Volumes in which selected Gas Sensors reside will the exterior-portal automatically open.
When activated with the exterior-portal open, the system will automatically close the exterior-portal and will activate all selected [[Active Vent]s to pressurize the chamber with interior-atmosphere. Only after the airlock's internal pressure equals or exceeds the 101 Pa will the interior-portal automatically open.
Materials
Material requirements for a minimum Atmosphere to Vacuum Airlock are:
- 2 x portals: variants of either Kit (Airlock), Kit (Blast Door), Kit (Door), or Kit (Docking Port)
- 1 x Kit (Consoles) Console
- 1 x Circuitboard (Advanced Airlock)
- 1 x Glass Sheets
- 1 x Data Disk
- 1 x Kit (Sensors) Gas Sensor
- 1 x Kit (Active Vent)
- 1 x Kit (Passive Vent) (optional)
- 1 x Kit (Flashing Light) (optional)
- 1 x Kit (Power Controller) (optional)
- 2 x Kit (Pipe)
- # x Cable Coil
Construction
A minimum Atmosphere to Vacuum Airlock can be constructed using the following instructions:
- Place both Portalsone Large Grid apart with the power and data ports facing into the airlock's interior.
- Using the Labeller, rename each door as "Interior-Door" and "Exterior-Door" appropriately.
- Enclose the six remaining sides of the airlock chamber with airtight frames, walls, or windows.
- Place Console, Active Vent, Gas Sensor, and optional Flashing Light and Power Controller somewhere within the airlock's interior.
- Ensure all placed devices are attached to the same Wire Network including the portals' power and data ports.
- Ensure the airlock's wire network is connected to an active Power Supply and all devices can receive power.
- Attach a Pipe Network to the Active Vent large enough to hold the volume of the airlock or pass it through to a Passive Vent placed in the "interior" environment.
- Ensure "interior" pipe networks are not connected to any other pipe networks.
- Insert Circuitboard (Airlock) into the console, then place the Glass Sheet onto the console.
- Insert Data Disk into the side slot of Console then power on the Console.
- Use the console's up and down arrows to scroll through the list of devices. Click to select. Click again to deselect if incorrect
- Find and click "Exterior-Door" followed by all caps and green "EXTERIOR". NOTE: SELECT THIS FIRST!
- Ensure the Exterior-Door's lock-indicator has turned from green to red.
- Find and click "Interior-Door" followed by all caps and green "INTERIOR".
- Ensure the Interior-Door's lock-indicator has turned from green to red.
- Find and click "Active Vent" followed by all caps and green "VENT".
- Find and click "Gas Sensor" followed by all caps and green "SENSOR".
- Find and click "Flashing Light" followed by all caps and green "LIGHT". (optional)
- Remove Data Disk from the side slot of Console.
If there is an error the console screen will say so and the power light will flash yellow.
Troubleshooting
When powered, all associated doors and vents are locked, preventing their manual use even when power is subsequently denied. This can be a problem when trapped within an airlock during a power outage. Best practise is to ensure the airlock's wire network is connected to an emergency Power Supply such as a Battery Cell equipped Power Controller.
A pressurization phase will stall if there is not enough gas available to the all selected Active Vents to reach 101 kPa. Such a stalled pressurization phase can be skipped by clicking the yellow "Cancel Pressurize" button on a console.
An airlock depressurization phase will not complete until the Large Grid Volumes in which all selected Gas Sensors reside are depleted of atmosphere at which time the exterior door will open. Such stalled depressurization can be skipped by clicking the yellow "Cancel Depressurize" button on a console. In larger airlocks, ensure there is one Gas Sensor per Large Grid to prevent the premature opening of the exterior portal and the resulting loss of atmosphere.
