Domain of apllication
This InfoT is only intended for the Barco iCon H600 with software V1.00 or higher p resenting
shutdown error s i.e. :
• Projector is not shutting down (lamps do not go off) when going in standby
Shutdown failure
When shutting down the projector using the standby button, the Single board
computer
should go off followed by the projector (lamps, ...).
However, when the CPLD software running on the Power Box SMPS control board is o f the
older type (used in firmware < V1.00) the shutdown of the projector is not happening. This
is due to a failure in communication (interrupts) between Power Box and main controller
(firmware).
In other words when shutting down the projector :
1. the shutdown text box is displayed
Projector will go to standby.
