Page 5: 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. Fuse A fuse is located inside of the projector. When the POWER indicator is not lighting, the fuse may be opened.
Page 6: Mechanical Sensor Switches (Sw901, Sw1891)
Circuit Protections Mechanical sensor switches (SW901, SW1891) LED indicators This projector provides 2 mechanical sensor switches, the one is for filter car- tridge switch (SW1891) and the other one is for lamp cover switch (SW901). The filter cartridge switch detects whether the filter cartridge is installed cor- rectly.
Page 7: Temperature Sensors, Wind Sensors
Circuit Protections Temperature sensors, wind sensors The projector provides 2 temperature sensor ICs, 1 thermistor, and 1 wind sensor on the intake duct. These devices are monitoring the surrounding temperature of the lamp, panel and intake duct, and the wind sensor is monitoring airflow passed through the air filter in the intake duct.
Page 8: Power Failure And Fan Lock Detection
Circuit Protections Power failure and fan lock 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.
Page 9: Maintenance
Maintenance Replacing the Filter Cartridge Filter prevents dust from accumulating on the optical elements inside the projector. Should the filter becomes clogged with dust particles, it will reduce cooling fans’ effectiveness and may result in internal heat buildup and adversely af- fect the life of the projector.
