Illumination unit read
This error occurs if there is no I²C communication between the illumination unit and the projection unit.
This error usually occurs when starting up the projector.
If this error bit is set, the dimmer motor and the motor of the mirrors in the illumination unit are not running.
• Switch off the projector, check the power cable and switch it on again.
It is not recommended to manually reset of the error, since this only affects the error bit,
but not the error itself.
Brightness
Brightness is checked regularly with respect to the target. If the achieved brightness is too high or too low, the
brightness checkbox is ticked.
Manual reset of this error makes no sense.
Lift error
This error occurs if the lift did not reach the switches at its upper and lower end position, respectively.
Manual reset of this error makes no sense.
To solve the problem, call Barco Support!
Reference Search
This error occurs if the mechanical dimmer cannot find its home position.
Firmware release 2.0 provides a new algorithm which ensures that there is at least some light on the screen.
With Firmware release 1.x the screen remains dark.
Switch off the projector and switch it on again. If the error still remains, call Barco Support!
Lamp door
This error occurs if a lamp door is opened. When the error bit is set, a counter starts, and if the door is not closed
within the counter cycle of 15minutes, the projector will shut down. If the door is closed within this counter pe-
riod, the error bit and the counter will be reset, and the projector performs a lamp lift readjustment after closing
the door. This is required since the lamp lift could be at a shifted position.
