Barco OverView D Series User Manual page 55

Over temperature
A sensor which is located behind the tilt mirror in the illumination unit checks the temperature. In case a critical
temperature (40°C) is reached, the over temperature bit is set, the shut down cycle counter starts its countdown,
and the projector is shut down within five minutes to prevent the system from severe damage.
If desired, the countdown counter can be disabled and thus over temperature protection..
It is highly recommended NOT to switch of over temperature protection.
In case the temperature drops within the countdown period below the critical limit, the countdown counter
stops, and the over temperature bit is reset automatically.
Under Voltage Error
This error occurs if the voltage of the power factor correction board is below a critical limit.
If DMD parking is enabled, the DMD will be parked after 10ms.
If the error is resolved during this time (practical not possible), the DMD parking will not be done.
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.
