27.1 LPS diagnostic LED’s
Status LED’s on LPS unit
The LPS module contains in total 10 status LED’s. 5 LED’s per LPS unit. One orange, three green and one red LED. The orange
LED “LVPS OK” lights up immediately after the projector is switched on. All other status LED’s of the LPS unit remains off. This is
the standby status of the LPS unit. Once the command is send to the LPS units to start up the projector lamp the green LED’s are
lighting up one after the other. First the green LED “PFC OK”, then the green LED “LPS OK” and finally, when the lamp is ignited,
the green LED “LAMP ON”.
The red LED “ERR” remains off unless an error is detected inside the LPS unit or both LPS units where ordered to shutdown due to
a malfunction somewhere else inside the projector.
