Each FAN sense signal undetectable
a Fan rotation signal is not detected
for more than 5 sec.
Each FAN sense signal
a Fan rotation is lower than 70% of
target for more than 5 seconds
Connector disconnection
Fan control circuit failure
Fan rotation error, end of life
If one of the fans stops,
the projector does not
shut down and reduces
the LD output power until
turning off.
If more than two fans have
an error, the projector shut
down.
(Warning) Each FAN sense signal
a Fan rotation is lower than 80% of
target for more than 5 seconds
TEMP blinks 2 times
