Digital Projection LIGHTNING 10sx And LIGHTNING 15sx User Manual

LED Indicators
There are 3 Light Emitting Diodes on the front of the projector which indicate the
status of the projector. The top red LED is used to indicate that power is applied to
the projector and that it is turned on. The middle green LED indicates normal 
operation and flashes when the projector is receiving a signal from the remote 
control unit. The bottom red LED indicates that the lamp has failed or is switched
off. For further information see System Operation, C—6.

Lenses
Four zoom lenses have been developed specifically for the LIGHTNINGsxrange of
projectors; zoom ratios 1.5 - 2.0:1, 2.0 - 2.5, 2.5 - 4.0:1 and 4.0 - 7.0:1.
Using a lens adapter, the lenses developed for the POWERgvseries may also be
used, albeit with modified throw ratios and limited lens shift capabilities.
Motorised Lens Mount
The LIGHTNING sxrange of projectors incorporate a motorised lens mount. This
mounting allows you to control the zoom/focus via the remote control.
As the lens mount...

Optics
The lamp faces onto a cold mirror which directs the light beam into a condenser. 
A prism then splits the concentrated beam from the condenser into red, green and
blue light using dichroic filters and directs the light onto separate DMDs™. The
images produced by the three DMDs™ are then combined by the prism to form a
full colour image and directed into the lens for projection.
The condenser is precisely aligned in the factory. If it is moved there could be a
reduction in light output and image...

Inputs 1, 2, 3- Each of these inputs can be used for different signal sources. RGB,
Hs Vs and Hs+Vs are used with a computer input, Composite/G is used with a
composite signal (such as NTSC), C and Y (S-VIDEO) are used with a VHS video
player and Y Pr Pb are used with Betacam or component sources.
Select LEDs- The input card LEDs indicate which input should be used with the
current channel. If the projector cannot find a valid signal, the LED flashes.
Inputs 4 & 5- These inputs provide for standard...

Digital Micromirror Devicesª
A Digital Micromirror Device™ (DMD™) is a digital light modulator fabricated
from moving aluminum mirrors. Each mirror, which acts as a pixel, is suspended
between two posts by a thin torsion hinge and can be tilted to the left to produce 
a bright pixel or to the right for a dark pixel.
There are three DMDs™ in the projector, one for each of the primary colours, each
containing 1,310,720 mirrors arranged in a 1280 x 1024 array.
Cooling System
During normal operation...

Power supplies
The General Power Supply provides a range of low voltage rails to the electronics.
The Xenon Arc Lamp has a separate high current power supply.
High Voltage, Danger of Death - the arc lamp power supply has a 30kV strike
pulse mechanism, which is active during lamp switch-on.
Remote Receiver
The optional remote receiver is used to pick-up infra-red signals from the remote
control unit and relay them to the projector.and also provides a hard wire interface
between the remote control and the...

Integrated Keypad
An integrated keypad is provided on the rear of the projector to allow the projector
to be controlled without the remote control. The operation of this keypad is identical
to that of the remote control (see System Operation, C—1 for further details).
Remote Control
All the functions of the LIGHTNINGdisplayare controlled using the remote control
or the integrated keypad on the rear of the projector. The remote control can be 
connected to the projector via the remote receiver or hard...

System Installation
INSTALLATION
LBV00056; Revision A - 23/08/99 

This installation section explains how to install the projector for optimum results.
To do this, it is necessary to determine the following:
1. The type of screen and whether front or rear projection is to be used.
2. The projector location and therefore the type of lens to be used.
3. The method of mounting for the projector.
4. The type of input source to be used with the projector.
Screen Requirements
As virtually all commercially available screens will give a pleasing image you
should choose...
