1.10.3.1. Action in lamp failure (burnout or explosion)
The lamp changer can detect the lamp failure and swaps it for spare lamp automatically.
1. When it detects the lamp failure, the lamp status is automatically recognized as “JUNK” and
memorized in the lamp memory.
2. If the status of spare lamp is “NEW” or “USED”, the auto-lamp changing starts. “

starts blinking on the screen to induce to replace the spare lamp. You can select no
indication setting (chapter 1.5.3.11, on page 24).
3. If the spare lamp status is “JUNK”, the projector tries to ignite current lamp once without
auto-lamp changing. If it succeeds to ignite, it continues to work. Otherwise, the status
indicator shows error code, “1.” (chapter 2.4, on page 70).
Even if the status is “JUNK”, in the case that turning off/on has been performed during this
status, auto-lamp changing starts. If it succeeds to ignite, it continues to work. Otherwise, the
status indicator shows error code, “1.”.
1.10.3.2. Action in brightness deterioration
When the luminous sensor detects the brightness deterioration, the lamp changer swaps it for
spare lamp automatically. You can set three types of starting condition of auto-lamp changing,
NORMAL (50% of initial brightness), LONG (30% of initial brightness) or OFF (no swap due to
brightness deterioration) (chapter 1.5.3.14, on page 25). You can display the pre-announcement
of auto-lamp changing on screen (chapter 1.5.3.11, on page 24).
The initial brightness is automatically read 5 minutes after the auto-lamp changing. If you turn off
the power during auto-lamp changing, the initial value will be read in the same way when you will
turn on again.
1. When it detects brightness deterioration according to the luminous sensor, the lamp status is
automatically recognized as “USED” and memorized in the lamp memory.
2. If the status of spare lamp is “NEW”, the pre-announcement of auto-lamp changing is
displayed on screen and auto-lamp changing starts 5 minutes later. “

on the screen to induce to replace the spare lamp. You can select no indication setting
(chapter 1.5.3.11, on page 24).
If the spare lamp status is “USED” or “JUNK”, the auto-lamp changing doesn’t work.
