Mechanical sensor switches (SW901, SW1891)
This projector provides 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. If the filter cartridge is not installed correctly, the projector cannot turn
on. In this case, the LAMP indicator is lighting and other indicators are blink-
ing.
The lamp cover 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. In this
case, the LAMP indicator is lighting and LAMP REPLACE indicator is blink-
ing.
