Page 5: Circuit Protections
Circuit Protections This projector provides the following circuit protections to operate in safety. If the abnormality occurs inside the projec- tor, 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.
Page 6: Thermostat (Sw901)
Circuit Protections Thermostat (SW901) There is the thermostat (SW901) inside of the projector to thermostat detect the internal temperature rising abnormally. When the internal temperature reaches near 100˚C, the thermostat (SW901) opens to stop the operation of the power supply circuit. The thermostat will automatically return to normal condi- tion when the internal temperature becomes normal (about 60˚C).
Page 7: Temperature Sensors (Th901, Th90, Ic8841)
Circuit Protections Temperature sensors (TH901, TH902, IC8841) The projector provides a temperature sensor IC on the Main board and thermistors. The temperature sensor IC monitors around the lamp house, the thermistors are placed on the blue panel holder and on the intake duct. - Internal temperature sensor A (IC8841) (around the lamp house) - Panel sensor B (TH90) (around the blue panel) - Room temperature sensor C (TH901) (around 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 Cleaning the Air Filter 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. If a “Filter warning” icon (yellow or red) appears on the screen and the WARNING FILTER indicator lights or blinks, clean the filter immediately.
Page 10: Lamp Replacement
Maintenance Lamp Replacement When the projection lamp of the projector reaches its end top control of life, the Lamp replacement icon appears on the screen and LAMP REPLACE indicator lights yellow. Replace the lamp with a new one promptly. The timing when the LAMP REPLACE indicator should light is depending on the lamp mode.
Page 11: Resetting The Lamp Counter
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 7 8 buttons to move the red framed pointer to the Setting Menu icon.
Page 12: Quick Maintenance
Maintenance Quick maintenance This projector provides a prism 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. Loosen 1 screw-A and open the prism cover panel. .
Page 13: Prohibition Of Motor Control
Maintenance Prohibition of motor control This projector provides a function to prohibit the operation of motors. After installing the projector and then setting up this function. You can protect the unexpected operation by the users. All the motor controls, Focus, Zoom and Lens- shift, will not be operated.
Page 14: Security Function Notice
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.
