Introduction to the X-ray system
26 XTM0522-B1 XT H 225 X-ray System
4.2 Operator console
The operator console is a single unit that combines the controls used to operate the system
and the joysticks used to move the sample manipulator. It contains the following controls:
• An EMERGENCY STOP button.
• SYSTEM POWER on (green) and off (red) buttons.
• XRAY POWER on/off button (white).
• An INTERLOCK key switch.
When the INTERLOCK key switch is in the OFF position, it is not possible to generate
X-rays. Always turn this switch to the OFF position and remove the key when performing any
maintenance operations, such as changing the filament in the source.
1. ESD earthing point. Allows attachment of E.S.D. wristbands or other equipment to earth
to avoid static discharge damaging electronic components.
2. EMERGENCY STOP. Activated by pushing the red knob fully inwards, when all electrical
power to the machine will be immediately cut (with the exception of the computer to
prevent data loss). After the emergency situation has been resolved, the knob can be
twisted and lifted to restore power. The system must be powered up again before it can
be used.
The emergency stop also forms part of the safety interlock system.
3. X RAY POWER. Illuminates white when pressed and applies electrical power to the
vacuum pump circuit and X-ray system (SR controller, high voltage generator and, if
fitted, rotating target controller). X-rays can be produced as soon as the vacuum reaches
a satisfactory level.
4. INTERLOCK key. Enables (ON) and disables (OFF) X-ray generation; part of the safety
interlock system
5. SYSTEM POWER On. Illuminates green when pressed and applies electrical power to
the main circuits.
6. SYSTEM POWER Off. Cuts electrical power to the main circuits when pressed.
7. Two USB 3.0 ports. Provide easy access for USB devices.
8. X-Y axis manipulator joystick. Moves the manipulator table in the +/- X/Y direction as
indicated.
9. Image zoom manipulator joystick. Changes the geometric magnification by moving the
sample towards or away from the X-ray source.
10. Tilt/rotate manipulator joystick. Tilts the sample stage or rotates the turntable around
the axis indicated.
