System operation for CP4440-RGB and CP4450-
RGB projectors
Understand the correct sequence for powering up and oper
ating CP4440-RGB and CP4450-RGB
systems.
The connected chiller must always be turned on first and turned off only after the projector is turned
off. Once the chiller is connected to AC and the chiller communication cable is connected to the
projector, the projector controls the chiller automatically to maintain the required coolant temperature.
The system is ready to operate when the following steps are completed:
1. The connected chiller unit is powered on.
2. The projector's main power switches are on.
3. Communication between the projector and the connected chiller is confirmed and coolant
temperatures are correctly maintained.
If a thermal shutdown occurs in a dual projector installation, verify the chiller communication
cables are connected correctly between each projector-chiller pair. This makes sure no cross-
connection exists relative to the coolant lines.
Turning on or off the projector
Turn on the projector to display content or turn off the projector to conserve energy or service the
projector.
In the right toolbar, select and hold Power.
If the light source is on when turning off the projector, the light source automatically enters a
ten-minute cool-down period.
