Chassis Description Power failure detection system Detection of Power failure Projector provides a protection circuit to prevent the secondary failure when the power failure, fans failure or tem- perature failure occurs on the projector. The power failure detection lines "MAIN_S-5V_PF", "GAM_12V_PF", etc. are connected to the main power supplies and fans.
Error History Log This projector provides the error history log function. To check the logs, you need to enter the service mode and select Group No. "91" and Item No. "0" to "49". The error code is displayed on the Data column. The description of the error code is listed on the table below.
Chassis Description Diagnosis of Power Failure with RS-232C port This projector provides a function to get the error information of the projector by using the RS-232C serial port for the power failure diagnosis. The further error information of the power failure and fan failure can be found out by using this function. Diagnosis procedure Connect a RS-232C serial cross cable to SERIAL PORT IN on the projector and serial port on the PC.
