Release the Motion Enable Buttons
If the Motion Enable Buttons are released during Patient Positioning Device (PPD)
movement, the PPD performs an emergency stop. If you release these buttons
before releasing the currently pressed Move button, the motion stops abruptly.
Only press the Motion Enable Button when the patient is safely restrained on the
couch or outside the moving equipment operating range.
The movement can be resumed by pressing the Motion Enable Buttons, followed
by the chosen Move button.
Press an Emergency Stop Button
Note: Emergency stop buttons and TSS interlocks exist on a level local to your
treatment room and system-wide. The description in this section pertains to the local
level only.
If an emergency stop button local to your treatment room is pressed during Patient
Positioning Device (PPD) movement, motion stops immediately.
After using an emergency stop button local to your treatment room to stop the PPDs,
the emergency stop button and the Therapy Safety System (TSS) must be reset.
After the emergency stop button and TSS are reset, the following may also be
required:
Recovery enabling beam production
Recovery of gantry movement (for GTR only)
Recovery of PBS Dedicated snout and PPS movements
Recovery enabling beam in TR
Recovery enabling X-ray high-voltage
Verification of proper operation
Successful daily calibrations (e.g., variable collimators)
WARNING Emergency stop buttons shut off energy to most components in the
Proton Therapy System (PTS). However, the electrical power to some
components will not be interrupted, so be aware that electrical hazards
and faults (faulty parts made live or induced fire) may still be present.
