6-18
In Cold Standby mode, since the replaced lamp is the inactive lamp, after resetting the error, there is no lamp
check, and the lamp remains switched off. The lift can be moved again. If then the system changes the active
lamp by means of the lift, the new lamp is tried to be lighted. If it is a flop, the error bit is set again, and within
about 5 seconds, the projector switches back to the lamp which has been the active one. Then the lift is locked
again.
In Cold Standby, after switching the active lamp, the lamp which has been active at that
time is only switched off if the second lamp succeeds in being switched on.
Fan
OverView D series employs two fans: one which is located behind the filter pad frame and connected to the illu-
mination unit and the projection unit, and one which is located beneath the bottom lamp.
Both fans are mandatory for operating OverView D, and in case one of them is out of order, it need to be re-
placed immediately!
The status of both fans together can be derived from the fan LED. (The fan LED is the bottom LED of the three
status LEDs).
Fan LED green: both fans work
Fan LED is red (static): fans are off!
Fan LED is blinking red: a fan error has occurred. At least one fan is not running
The fan error is an auto-updated error. It’s of no use to reset the error manually since the fan is
monitored continuously. In case the error is solved, error bit is reset automatically. In case the
error persists, the error bit is set (again).
In case the error is not reset automatically, call Barco support.
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.
