1. Change the Separator Return flow from 8 to 12 SLM, using "THCD_401_Main.vi".
2. Wait for 5 minutes.
   1. This step is to accumulate LHe in the separator.
3. Fill the nose with LHe manually.  Can skip this step if the nose LHe level is already high, >70%.
   
   1. Set the turn of the bypass valve to "1.0", by entering the value to the "Set Turns" box (or clicking the up arrow of the box multiple times).
   2. Confirm that the Main Return flow increases on the right-side strip chart in this page;  https://e906-gat1.fnal.gov/data-summary/e1039/target-par-preset/return_flow.php
   3. Increase the turn step-by-step (wait for 20 seconds per +0.1 turns), until the Main Return flow reaches about 50-80 SLM.  Usually the turn should be 1.4-1.8. 
   4. Wait until the nose LHe level becomes 80%.  A higher level (80-100%) is acceptable, but never keep filling above 100%.
      1. If the level does not start going up in 5 minutes; close the valve, wait for 10 minutes, and try again.
   5. Close the bypass valve, by setting the turn to "0".
   6. Confirm that the Main Return flow is ~5 SLM or less, and the nose LHe level is going down slowly.
4. Enable the automated control of the bypass valve.
   
   1. Confirm that the "Set Point of He Level" is 75%.
   2. Click the toggle switch labelled "Automated Bypass-Valve Control".
   3. Enable the SMS (Discord) alarm, by clicking the toggle switch labelled "SMS".
   4. Report on Discord that the automated control has started.  Kenichi has to check the behavior at the beginning.
