Fault Messages
The fault messages produced whilst in the application are
directly controlled by the software written by Thermo Fisher
Scientific whereas errors reported from the motherboard Bios
or the Window’s operating system will be supplier dependent.
On switching ON the screen will remain blank for several
seconds whilst the Bios carries out basic checks on the
motherboard. The screen will eventually show scripting which
details the progress of these initial tests. Should a fault be
found the process will halt with the fault/error detailed. This
should be recorded and reported to Thermo Fisher Scientific’s
service department. The equipment cannot be used until the
fault is removed.
It must be noted that a failure of the LCD backlight module will
leave the display blank even though “boot-up” is taking place
correctly.
In a normal boot-up the Bios’ sequence of tests will be
followed by loading the operating system from the disk drive,
signalled by the Thermo Fisher Scientific log screen. Any
failure here will result in a “blue” screen. Again you will need
to contact Thermo Fisher Scientific’s service department if this
does occur.
Finally the application software will be loaded and the SAM12
User screen will be displayed.
The application is entered with tests to verify the detection
components are working correctly. Should a failure occur
during these initial checks then the “Out of Service” message
will appear on the message bar and one of the following will be
displayed on the message bar:
1. Unable to set detector alarms
2. Database Offline
3. Unable to Configure Detector Subsystem
4. Invalid Language Setting
5. Default Calibration has no Alarms
