Uninterruptible Power Supply (UPS)
If the power failures occur occasionally it is recommended to use the microscope UPS, which maintains the
vacuum in the electron source section.
In case the microscope system is powered by the UPS and a mains power failure happens, the system starts 10
minutes countdown to switch to the safe mode. User is informed about the countdown progress in the application
status window. If the mains power is recovered within this time, the countdown is cancelled and nothing happens.
After 10 minutes of continuous power off a shutdown to the safe mode with following actions is activated:
• FEG emission is gently switched off
• Ion emission is gently switched off
• Chamber is vented
• UI is stopped
• xT Microscope server is stopped
• Microscope console is switched off to Standby mode
• Microscope PC and the Support PC (if present) are switched off
WARNING!
Because the Emitter IGP’s are supported by the UPS, some parts of the microscope are still under power.
To return the system to an operation follow the startup procedure (see Chapter 2). When the xT microscope Server
is launched the first time from the safe mode, a dialog is shown to inform a user.
Note
If the Startup procedure fails, contact a FEI authorized service engineer.
