Thermistor and Temperature Sensor Operation

Analog/Digital converters in IC104 on the MA board detect the temperatures of the Optical
Engine and Power Supply sections by means of the two Lamp Thermistors at intervals of 1
second. Based on the measurement results, the CPU controls fan operations and power supply
shutdown operations as necessary.

See Section 2.8.2 for more information on fan operation, and Section 2.9 for more information
on the LED status indicators.

2.8.2 Fan Operation

There are five cooling fans inside the projector. These fans discharge heated air produced by
the Lamp Assy., power supply unit, and ballast unit.
