Page 11: Circuit Protections
Circuit Protections This projector provides the following circuit protections to operate in safety. If the abnormality occurs inside the pro- jector, it will automatically turn off by operating one of the following protection circuits. Fuses (F601, F602, F603) Fuses are located inside of the projector. If all the indicators are not lighting, the fuse (F602) may be opened.
Page 12: Thermal Fuses (Sw903, Sw904, Sw905, Sw906)
Circuit Protections Thermal fuses (SW903, SW904, SW905, SW906) There are the thermal fuses (SW903, SW904, SW905 and SW906) inside of the projector to detect the internal temperature rising abnormally. When the internal temperature around lamps reaches near 99˚C, the thermal fuse will open to cut off the power supply to the lamp power circuit.
Page 13: Temperature Sensors, Wind Sensors
Circuit Protections Temperature sensors, wind sensors The projector provides 2 temperature sensor ICs, 1 sensor on the main board and 1 sensor on the ex temp board, and 1 wind sensor on the intake duct. The sensor ICs monitor surrounding temperature of the panels/prism, and surrounding temperature of the intake duct, and the wind sensor monitors airflow passed through the air filter in the intake duct.
Page 14: Power Failure, Fan Lock And Filter Error Detection
Circuit Protections Power failure, fan lock and filter error detection The projector provides the detection circuits of the power failure and the fan lock. When the detection circuit detects an error at the power supply line or at the fan operation circuit, the projector will turn into the standby mode to protect the other circuits defective.
