16.1 Status LED indications
The status LED on the rear top of the projector, has only one indication; constant red illumination. This
indicates a major system failure. A more complementary indication will come on later versions of the software.
16.2 LED
’
s on Thermal Hub and Mainboard.
On the Thermal Hub board and the Main board, there are several LED
’
s which will illuminate if a failure occurs
on the board. It is primarily the different voltages on the boards which are monitored, but also some other
control parameters. The table and figures below show the failure matrix and the location of the different LED
’
s.
