Liquid Cooling Pumps
Article no. / Description 502-0372-xx Liquid Cooler
The primary cooling system comprises
fi
ve (5) liquid cooling pumps, four for the general system and one speci
fi
cally for DMD cooling.
8.3
Fans
RPM control of each fan is tightly enforced by the system processor via FPGA, and will adapt RPM based on the temperature
differential between air inlet and air outlet at any given time. Fan speed can be affected by the mode the projector is running in
(e.g. Quiet mode). To maximize lifetime and minimize stress on critical components, the fan system runs idle when the projector is
in standby (projector is shut off, but power is applied). If a fan operates outside normal parameters (+/- 200 rpm) for more than 2
minutes, the system will shut down and status LED will indicate thermal failure (red
fl
ash). After toggling mains power, the system
may be restarted and fan monitor (in service menu) activated to properly identify which fan is inoperative or operating outside nominal
values. All nominal RPM values are recorded in Desktop mode.
Refer to Chapter 8.6 System Thermal Diagram for details regarding data for the fans.
8.3.1
Fan Radiator
Fan Radiator 1, 2, 3, 4, 5, Driver are all axial-
fl
ow fans which operate by increasing the pressure of air
fl
owing through it.
There are six (6) axial fans (119x25.5) in the system: 5 pcs for the radiators, and 1 pcs for the DMD.
