11. Lamp Power Supply
11.1 LPS module diagnostic LED’s
Status LED’s on the LPS module
There are 8 diagnostic LED’s per LPS module. Four orange, three green and one red LED.
The orange LED “LVPS OK” lights up immediately after the projector is switched on. At the same time, the heartbeat LED starts
blinking. All other status LEDs of the LPS unit remain off. This is the standby status of the LPS unit. Once the command is sent
to the LPS units to start up the projection lamp, the green LEDs are lighting up one after the other. First the green LED “PFC OK”,
then the green LED “LPS OK” and
fi
nally, when the lamp is ignited, the green LED “LAMP ON”. The right orange of the upper row
blinks. This is the heartbeat signal
The red LED “ERR” remains off unless an error is detected inside the LPS unit or when both LPS units are ordered to shutdown due
to a malfunction somewhere else inside the projector.
