Circuit Protections This projector provides the following circuit protections to operate in safety. If the abnormality occurs inside the projector, 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.
Circuit Protections Mechanical sensor switches (SW901, SW1891) Led indicators This projector provides 2 mechanical sensor switches, the one is for filter switch (SW1891) and the other one is for lamp cover switch (SW901). The filter switch detects whether the filter is installed correctly. If the filter is switch detects whether the filter is installed correctly.
Circuit Protections Temperature sensors The projector provides 2 temperature sensor ICs and 1 thermistor on the intake duct. These devices are monitoring the surrounding temperature of the lamp, panel and intake duct are monitoring 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 af- fect the life of the projector.
Maintenance Resetting the Filter Counter Be sure to reset the Filter counter after replacing the filter Filter counter 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 or the SELECT button. Use the Point ed buttons to select Filter counter and then press the SELECT button.
Allow a projector to cool for at least 45 minutes before you open the Lamp cover. The inside of the projector can be- come very hot. New Lamp order rePLAceMeNt LAMP Model PLc-WM4500/PLc-WM4500L type No. PoA-LMP137 Service Parts No. 610 347 5158 -11-...
Maintenance How to check Lamp Used Time The LAMP REPLACE indicator will light yellow when the total lamp used time (Corresponding value) reaches 3,000 hours. This is to indicate that lamp replacement is required. The total lamp used time is calculated by using the below expression, Total lamp used time (Corresponding value) = eco + normal x 1.5...
Maintenance Quick maintenance This projector provides a cabinet 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. Loosen a screw-A on the lamp cover and slide it to open (Fig.
Maintenance Lens Installation When replacing the lens or using an optional lens, install the lens by following the instructions below. removing the lens Shift the lens to the center position by using the Lens Release button Lens shift function. Turn off the projector and unplug the AC power cord.
Maintenance Using the Lens Antitheft screw This projector provides a Lens antitheft screw to protect the projection lens stolen from a suspicious person. Mount the Lens antitheft screw by following the instructions below. Mounting the Lens antitheft screw Loosen a screw-A on the lamp cover and slide it to Lamp cover open (Fig.
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.
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.
