System Shutdown - Thermo Scientific Apreo User's Operation Manual

System shutdown

In case of emergency, bring the system to the Complete shutdown state by following this procedure:
1. Click on the Column module / Beam On button to stop the
accelerating voltage. A Column module / Source progress bar
indicates the actual status; the button turns gray when
finished.
2. Click on the Vacuum module / Vent button to vent the chamber.
3. Switch off the Emitter with the use of the 5 - Emitter Startup
alignment – Step 2 of 2.
4. Click on the xT microscope Server software / Standby button.
This stops the UI, the xT microscope Server application
services, and the console (the green power button on the
microscope front control panel changes to amber).
5. Shut down Windows 7™ and switch off the monitor.
6. If needed, disconnect the power cord and any other input /
(h)
output used.
Note
f)
Switching off the console when the Emitter is on is not optimal for
the emitter – it may deteriorate its filament lifetime.
g)
The system can be left in this state if electrical power is supplied to
the instrument because the pumps are running and pumping the
column.
h)
The Complete shutdown procedure brings the system to the non-
powered state, in which the vacuum in the column area is no longer
supported by running pumps. All valves are closed, and the electron
column and specimen chamber areas are vented. Normally this is used
for system transportation or for service actions, such as repair to
essential systems (electrical and air supplies).
