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 lightning, the fuse may be opened.
Circuit Protections Mechanical sensor switches (SW1891,SW1861) This projector provides 2 mechanical sensor switches, the one is for filter cartridge sensor switch (SW1891) and the other one is for lamp cover sensor switch (SW1861). The filter cartridge sensor switch detects whether the filter cartridge is installed correctly. If the filter cartridge is not installed correctly, the projector cannot turn on.
Circuit Protections Temperature sensors, wind sensors The projector provides 3 temperature sensor ICs, 2 sensors on the Main board and 1 sensor on the RC front board, and 1 wind sensor on the intake duct. The sensor ICs monitor surrounding temperature of the lamp house and pan- els/prism, and room temperature, and the wind sensor monitors airflow passed through the air filter in the intake duct.
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.
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 affect the life of the projector.
Resetting the filter counter Filter counter Be sure to reset the filter counter after replacing the filter and the filter cartridge. Press the MENU button to display the on-screen menu. Use the point ed buttons to select Setting and then press the point 8 button or the SELECT button.
Maintenance Lamp Replacement When the projection lamp of the projector reaches its end of life, the lamp replacement icon appears on the screen and LAMP REPLACE indicator lights orange. Replace the lamp with a new one promptly. The timing when the LAMP REPLACE indicator should light is depending on the lamp mode.
Maintenance Resetting the lamp counter Be sure to reset the lamp counter after the lamp is replaced. When the lamp counter is reset, the LAMP RE- PLACE indicator stops lighting and the lamp replacement icon disappears. Lamp counter Press the MENU button to display the on-screen menu. Use the point ed buttons to select Setting and then press the point 8 button or the SELECT button.
Maintenance Cleaning After long periods of use, dust and other particles will accumulate on the LCD panel, prism, mirror, polarized glass, lens, etc., causing the picture to darken or color to blur. If this occurs, clean the inside of optical unit. Remove dust and other particles using air spray.
Maintenance Quick maintenance This projector provides a cabinet front cover on the cabinet top to enhance the service maintenance. This enables service personnel to align the optical adjustment or replace the optical parts without disassembly the cabinet top. 1. Press and hold the release button on the cabinet front cover and slide the cover frontward to take it off (Fig. 1). 2.
Security Function Notice This projector provides security functions such as "Key lock", "PIN code lock" and "Logo PIN code lock". When the projector has set these security function on, you are required to enter correct PIN code to use the projector. If you do not know the correct PIN code to the projector, the projector can no longer be operated or started.
