Filter cartridge
This projector provides mechanical sensor switches, the one is for filter cartridge sensor switch (SW6581) and the
other one is for lamp cover sensor switch (SW90). The filter cartridge sensor switch detects whether the filter car-
tridge is installed correctly. If the filter cartridge is not installed correctly, the projector cannot turn on.
The lamp cover sensor switch detects whether the lamp cover is closed securely. If lamp cover is opened or not
closed completely, the drive signal to the lamp circuit is cut off. After opening the lamp cover for replacing the lamp
ass’y, place the lamp cover correctly otherwise the projector cannot turn on.
