Stage description
Stage 1 : Projector is switched off. Input & Communication Unit is not active and the laser status light (LS) is
off.
Stage 2 : Projector is projector is booting. This process starts as soon as the power switch is switched on
(reference A, Image 4-4). This process takes several seconds and during this process the Power On/Off
button is blinking white. The laser status light remains off.
Stage 3 : Initialization. This process starts as soon as the projector has finished booting up. The initialization
of all electronic boards takes approximately two minutes and during this process the backlight of the Power
On/Off button is blinking blue. The laser status light remains off.
Stage 4 : Projector is READY. All electronic boards are up and running. On the local keypad the OK button,
Shutter button and the Menu Activation button become active. The backlight of the Power on/off button is
white. The laser status light remains off.
Stage 5 : The projector is in CONDITIONING mode. This process starts as soon as the On/Off button is
pressed when the projector is in READY mode (reference B, Image 4-4). The shutter automatically closes in
this stage for laser safety reasons. The laser status light remains off.
The first stage of the CONDITIONING process is the environmental checks. In this stage, the projector verifies
if it is safe to turn on the pump of the cooling circuit and to extract humidity from the sealed compartments
without having the risk of condensation. The temperature inside the sealed compartments is kept on ambient
level.
Once the projector has confirmed it is safe to start conditioning, the conditioning process itself will start. This is
indicated by the laser status light (LS) on the top of the projector. This light will flash a few times and will then
light up continuously white. The sealed compartments are cooling down from ambient to operating
temperature and humidity is extracted. The conditioning process takes approximately 3 to 20 minutes (exact
time depends on the environmental conditions).
Following substages take place during CONDITIONING:
Stage 6.1 : Checking ambient and internal conditions.
Stage 6.2 : Turning pump on. Reaching liquid flow target.
Stage 6.3 : Flow target reached. Conditioning humidity in the projector.
Stage 6.4 : Cooling started.
Stage 6.5 : Reaching liquid temperature target.
