2.1.3.Auto-lamp changing function (for Changer )

Changer is equipped with the auto-lamp changing function that can detect a lamp failure or a brightness deterioration to swap it for a spare lamp automatically.

The lamp is managed as three types of status, “NEW”, “USED” and “JUNK”. It is displayed on screen by [DISPLAY] button.

•NEW: New or not-deteriorated lamp

•USED: Deteriorated lamp below the threshold set in CHANGE MODE menu (chapter 1.5.1.18.2, on page 43)

•JUNK: Failed lamp

5 minutes after the auto-lamp changing, the lamp can be automatically adjusted to the suitable position to maximize the brightness (chapter 2.1.3.4, on page 79), and the initial brightness is automatically read. If you turn off the power during the auto-lamp changing, the initial value will be read in the same way when you will turn on again.

2.1.3.1. Action in lamp failure (burnout or explosion)

When a lamp failure is detected, the lamp is automatically swapped for a spare lamp.

1.When it detects a lamp failure, the lamp status is automatically recognized as “JUNK” and memorized in the lamp memory.

2.If the spare lamp status is “NEW” or “USED”, the auto-lamp changing starts. “☀” mark starts blinking on the screen to induce to replace the spare lamp (chapter 2.1.3.5, on page 80).

3.If the spare lamp status is “JUNK”, the product tries to ignite the current lamp once without auto-lamp changing. If it succeeds to ignite, it continues to work. Otherwise, the error indicator shows “1.” (chapter 3.5, on page 91).

Even if the status is “JUNK”, in the case that you have cycled the power during this status, the auto-lamp changing starts. If it succeeds to ignite, it continues to work. Otherwise, the error indicator shows “1.”.

2.1.3.2. Action in brightness deterioration

When the luminous sensor detects a brightness deterioration, the lamp is automatically swapped for a spare lamp.

1.When the luminous sensor detects brightness deterioration, the lamp status is automatically recognized as “USED” and memorized in the lamp memory.

2.If the spare lamp status is “NEW”, the pre-announcement of auto-lamp changing is displayed on screen and the auto-lamp changing starts 5 minutes later. “☀” mark starts blinking on the screen to induce to replace the spare lamp (chapter 2.1.3.5, on page 80).

3.If the spare lamp status is “USED” or “JUNK”, the current lamp is not swapped to keep

lighting.

In CHANGE MODE menu (chapter 1.5.1.18.2, on page 43), you can set the brightness to start the auto-lamp changing. There are three types of condition, 50% of initial brightness (NORMAL), 30% of initial brightness (LONG) or no swap due to brightness deterioration (OFF). The initial setting is NORMAL.
