The projector provides 3 temperature sensor ICs, sensors on the Main board and 1 sensor on the Sensor board,
and 1 wind sensor on the intake duct. The sensor ICs monitor surrounding temperature of the optical parts, and
surrounding temperature of the intake duct, and the wind sensor monitors airflow passed through the air filter in the
intake duct.
- Temperature sensor (IC881) is on the main board for monitoring the surrounding temperature of DMD module.
- Temperature sensor (IC1381) is on the main board for monitoring the surrounding temperature of optical unit.
- Temperature sensor (IC8811) is on the sensor board for monitoring the surrounding temperature of the intake
duct.
- Wind sensor (S901) on the filter box.

The projector is shut down and the WARNING TEMP. indicator is
blinking red.
When the temperature inside the projector reaches a certain level, the projec-
tor will be automatically shut down to protect the inside of the projector. The
LAMP indicator turns red brighter and the WARNING TEMP indicator blinks
while the projector is being cooled down. When the projector has cooled
down enough (to its normal operating temperature), it can be turned on again
by pressing the ON/STAND-BY button.
✔
Note:
• The WARNING TEMP. indicator continues to blink even after the temperature
inside the projector returns to normal. When the projector is turned on again, the
WARNING TEMP. indicator stops blinking.
