Lesson Module A-7: Personnel Safety System - pg 8

PSS Summary

To review:

  • Two types of control panels found at experiment stations communicate information to the user about the status of the PSS.
  • Green LEDs indicate that a particular component is configured to let beam into the station.
  • Two keys are needed to bring beam into a hutch -- a user key and the APS reset key.
  • A Search-and-Secure procedure must be performed before the doors on an experiment station are closed and locked, in order to take beam into a station.

After reading the materials in this training module, please see a Floor Coordinator for a personalized tour of the PSS, who will integrate these readings with the actual Personnel Safety System.
