9. INTERNAL ERRORS Error data is returned to the external control unit when an error has occurred. 9.1 Internal Error Data Status (Internal Error Status) Character HEX Definition 'E01' 45H 30H 31H Lamp did not light 'E02' 45H 30H 32H Lamp life exceeds guaranteed time 'E03' 45H 30H 33H IIC ACK error occurs 'E04' 45H 30H 34H Filter cover on the bottom of the unit is displaced 'E06' 45H 30H 36H Lamp suddenly goes out (Lamp Shut Down) while projecting (in Power ON mode) 'E07' 45H 30H 37H Fan is locked 'E08' 45H 30H 38H Internal temperature is too high. 'E09' 45H 30H 39H Temperature around air intake is going up abnormally. 'E0B' 45H 30H 42H Error occurred with the initialization of decoder. 'E0C' 45H 30H 43H Initialization of Video Sources (Areas) data was failed. 'E11' 45H 31H 31H Sub microcomputer is not boost up correctly. 'E12' 45H 31H 32H Initialization of DDIC/DDCTRL was failed. 'E20' 45H 32H 30H Sleep time function works and lamp was lit off. 9.2 Internal Error Data Parameters There are two parameters for Internal Error Data. Header ID SP Internal Error Status SP Parameter 1 SP Parameter 2 CR Each parameter shows the slave address (Parameter 1) and Sub-Address (Parameter 2) when an IIC ACK error (Error status: 'E03') occurs. The parameter type is "numeric value". * Two parameters are also returned when an internal errors other than IIC ACK errors occur. In this case, however, the parameter's numeric value has no meaning. Ex) Internal error data when IIC ACK error occurs with Slave address 'A0H' and Sub-address of '1F20H': '＆' ID SP 'E03' SP '00A0' SP '1F20' CR 10
