The lamp housing has a built-in thermostat which puts out the lamp when the temperature becomes 110°C.
Similarly, the power supply unit and lamp driver have thermostats which terminate power supply and driver operation
when the temperature reaches 120°C and 115°C, respectively.

The lamp will not light up unless the lamp cover is mounted.

When the lamp fails to light up, the status LED indicator starts flickering.  Different flickering intervals help identify
the cause.  (Refer to the figure at right and the table below.)

OFF (kept off)

ON (kept on)

Flickers with a cycle of one
second (0.5 sec. ON and
0.5 sec. OFF)

Flickers with a cycle of 4
seconds (2 sec. ON and 2
sec. OFF)

Flickers with a cycle of 8
seconds (4 sec. ON and 4
sec. OFF)

Flickers with a cycle of 12
seconds (6 sec. ON and
6sec. OFF)
