Power Failure, Fan Lock And Filter Error Detection - Christie LX1750C Service Manual

Circuit Protections

Power failure, fan lock and filter error detection

The projector provides the detection circuits of the power failure and the fan lock. When the detection circuit detects
an error at the power supply line or at the fan operation circuit, the projector will turn into the standby mode to protect
the other circuits defective.
The projector is shut down; and the STAND-BY indicator is
lighting and other indicators are blinking.
When the projector detects an abnormal condition (Power supply lines failure
, fans failure), it will be automatically shut down to protect the inside of the
projector and the STAND-BY indicator lights on and other indicators blink. In
this case, unplug the AC power cord and plug it, and then turn on the projec-
tor once again to verify operation. If the projector cannot be turned on and
these indicators are still lighting and blinking, unplug the AC power cord. See
the troubleshooting chapter.
CAUTION
DO NOT LEAVE THE PROJECTOR WITH THE AC POWER CORD
CONNECTED UNDER AN ABNORMAL CONDITION. IT MAY RE-
SULT IN FIRE OR ELECTRIC SHOCK.
