  • Page 37: Chapter 3 Theory Of Operation

    Chapter 3 Theory of Operation OVERVIEW The Model QS-550 Tubestand is a free-standing x-ray tube support device (i.e., does not require wall and/or ceiling mounting) that provides a wide range of tube positions through longitudinal, vertical, rotational, and transverse tubestand motions. The Handgrip Assembly is designed for operator convenience with ergonomically posi- tioned push button switches that enable tubestand movement when pressed.
  • Page 38 SID switch, which routes the +24 VDC to the Longitudinal Lock Coil L3. The longitudinal brake (magnetic lock) is activated, locking the x-ray tube in the current SID position. To re-activate the Auto-Stop function, both the Longitudinal Lock Release and Auto-Stop buttons must be pressed. Model QS-550 - Service Manual...
