The instrument status window displays real-time status information for the instrument components.
All parameters are arranged in a tree view.
In addition to showing numerical values of parameters (for example, pump speeds or component temperatures), the instrument status window uses icons to indicate the statuses of system components.
The messages window displays real-time information about the statuses of the instrument, the control service, or other programs.
It might display additional information. In case of an overheated turbomolecular pump, shut down the mass spectrometer.
To prevent permanent damage to components of the Q Exactive GC mass spectrometer, Thermo Fisher Scientific recommends calling a Thermo Fisher Scientific field service engineer.

A turbomolecular pump may be switched off because of one of the following reasons:

Turbomolecular pump is blocked
Failure of fans in turbomolecular pump Each of the above reasons might lead to an overheating of the pump.
When overheated, a turbomolecular pump switches off automatically to prevent its destruction.
