1. When the IP pressure (read on 3259 guage) is < 1 Torr, then start the PB turbo (VPTM:LI20:3175). 
2. If the oven turbo (VPTM:LI20:M3202) is already running then you can open valve 3201now3201 now.
   1. If it is not running, then first start the oven turbo, then open valve 3201.
3. When the 3259 guage reads <1e-2 Torr then you can open the FV-DS1 and FV-DS2 valves to start pumping through the roughing pumps.
   
   1. If the foreline closes immediately then the pressure is still too high in the beamline and the interlock tripped
   2. To clear the foreline interlock:
      1. Open the "Foreline Vlv Intlks..." page from the DPS full schematic page
      2. Push "Reset Interlocks"
      3. 
4. Start the turbopumps: 
   1. Open the DS1 turbo panel by clicking on the turbo symbol above "DS Stage 1" → Press Run
   2. Open the DS2 turbo panel by clicking on the turbo symbol above "DS Stage 2" → Press Run
   3. 
5. Confirm that the speed continues to increase. It should reach a nominal speed of ~27000 RPM after about 5 minutes and the vacuum should be reading on gauges 3259 and 3291 <1e-7 very quickly.
6. If the CC guage 3291 is not reading while the 3259 gauge reads<1e-5, then you have to turn 3291 on manually
   1. Open the 3291 gauge panel
   2. Press "Turn on" beside the words "Cold Cathode HV"
   3. Confirm that it powers on after a few seconds
