7.2 Shut Down
The instrument has been designed to run continuously. So it is not necess ary to turn it OFF
unless needed.
The maximum working values depend on the X-ray tube power. From a general point of view,
maximum values that can be applied are 55kV for high voltage and 45 mA for current. Be
careful, maximum current also depends on the focal spot size, 45 mA for LFF (long fine focus)
and 40 mA for FF (fine focus).
When the X-Ray diffractometer is not used for more than an hour, we advise to run the
generator at a power saving mode, 20 kV, 5 mA.
When the instrument is not used for more than two weeks, it can be shut down completely.
1.
Reduce the generator power to 0 kV and 0 mA.
2.
When the generator has reached 0 kV and 0 mA, quit all the software and terminate the
communication between the instrument and the computer (refer to the SymphoniX u ser
guide for more information).
3.
Push the red button labeled "Power OFF" located on the front panel. After you pushed it,
this red button will turn OFF and the white button "Power ON" will illuminate.
4.
Turn the main breaker located on the rear of the unit t o the "0-OFF" position.
5.
Close the cooling fluid supply about ten minutes after the generator reached 0 kV and 0
mA in order to properly cool down the X-Ray tube.
7.3 Emergency Stop
In case of any problem (electrical, radiation or mechanic al) there is an emergency stop button
located on the front panel of the instrument. Pushing the emergency button immediately
removes the power to the instrument, including the X-Ray generator. Be aware, that pushing
the emergency stop button will result in communication loss between the control computer
and the instrument.
CAUTION!
The emergency stop should not be used for routine shut down of the generator since
repeated rapid power shut downs may dramatically reduce the lifetime of your X -Ray
tube and damage the X-Ray generator.
7.4 Enclosure Light
The Light button allows to illuminates the enclosure while the door is closed. The button is
illuminated when the enclosure light is as well. Then, when the door is opened, the button is
illuminated whatever if it is pushed or released.
