8. Thermal management system
8.4
Thermal sensors
The Projector is equipped with a number of thermal sensors. This is both bimetal and thermocouple (P/N based) sensors, in order
to have both immediate thermal shutdown (bimetal), and also as a reading of the real time temperature. See Thermal Management
Diagram for a schematic overview.
8.5
Engine heatsink
DMD cooling is provided by Liquid Cooling Pump 5, and a dual Peltier module connected to a heatsink. The heatsink is used to
disperse the heat emitted by the illumination system and prevent the DLP® chip absorbing too much heat. The heatsink is a heat
pipe construction combined with a dual Peltier module. This ensures that the DMD device operates within its recommended thermal
envelope, and connects it physically to the Heatsink. A spring loaded mechanism in the heatsink ensures adequate tension of the
Peltier stud against the DMD device for optimal heat dissipation.
Always renew the thermal gasket on the stud when performing any service operation which constitutes re-
moving the Peltier/heatsink from the DMD device.

System thermal diagram
Figures in the nominal settings and lifetime settings charts may vary due to different operation conditions, including mounting posi-
tion, saturation of
fi
lters (if optional dust
fi
lter is installed and
fi
lter saturation sensor activates) etc.
