This variable indicates the status of the system.
The sysCurrentStatus is a bit map represented
as a sum, therefore, it can represent multiple defects
simultaneously. The sysNoDefect should be set if and only if
no other flag is set.
The various bit positions are:
1 sysNoDefect
2 sysOverHeat
3 sysFanRpmLow
4 sysVoltageLow
5 sysThermalSensorFailure
