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.
Arc Lamp
The projector uses a specialised, high pressure xenon arc lamp designed to operate
in conjunction with Digital Projections optical condenser system and specialised
power supply unit. The lamp achieves maximum brightness within 1 minute of
strike and is designed for an operating life of greater than 750 hours.
The operator is advised to switch off the lamp using the LAMP OFF button on the
remote control, and allow the cooling system to run on for ten minutes before
switching off the mains supply.
The lamp is contained in a special safety housing to dissipate heat and to make
changing the lamp as easy as possible (see Fault Finding and Maintenance, E—6).
The customer should never attempt to disassemble the lamp from its housing or to
dispose of it other than by returning it to Digital Projection.

							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 attaches to the lens, the mounting mechanism must be released
before a lens can be fitted or removed. To release the lens mount turn the mounting
lever anti-clockwise (upwards). After fitting a lens the lever should be turned 
clockwise to engage the mechanism.
When engaging the lens mount, the lens may have to be rotated slightly in order
for the lens mounting to connect correctly.

							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 display quality.
Electronics
The main electronic components of the projector are the Analogue Input Board, 
Digital Processing Card, Formatter Card and the three Display Boards (each of
which contains a Digital Micromirror Device™).
The Analogue Input Board, situated at the rear of the projector, converts analogue
inputs to digital signals and routes them to the digital processing card.
The Digital Processing Card stores the channel configurations and any on screen
adjustments such as brightness, contrast etc. These settings are applied to the
incoming signal for transfer to the Formatter Card.
The Formatter Card translates the digital signal into a format that the Digital
Micromirror Devices™ can read.
Analogue Input Board
The Analogue Input Board located at the rear of the projector provides all the
required connections for video, computer and remote control inputs. The input
board is split in three main sections - Source, Digital and Control (see opposite).

							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 considerable heat is generated inside the projector, 
therefore, an air cooling system is provided. This consists of a powerful fan which
draws cool air through specially designed air ducts within the case to distribute it
over the lamp and other components. The cooling system provides maximum 
cooling whilst minimising noise output.
Do not move or tamper with any seals or ducting panels on the projector or the
air flow could be disrupted and cause the projector to overheat. Always keep the
air inlets and outlets clear of any obstruction.

							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 projector.
The remote receiver is a small 75mm x 100mm x 25mm (3 x 4 x 1) matt black
box with mounting lugs on each end and an infra red sensor on the front. On the
underside there are 2 connection points:- a 15 way high density D style connector
for the projector and a 4 way LEMO connector for the remote control (refer to 
A—7 and D—18 for more information).
Hard Wired Remote Adapter
The hard wired remote adapter provides direct connection between the remote 
control and the projector without the need for the remote receiver as an interface.
The remote adapter is provided as standard with LIGHTNINGdisplay projectors.
The adapter consists of two cables - a 15-pin high-density ‘D’ type plug to ‘XLR’
socket with integral decoder circuit and an ‘XLR’ plug to 3.5mm stereo jack plug.
This cable assembly enables the user to extend the remote adapter using a standard
audio/video cable (refer to A—8 and D—20 for more information).

							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 wired remote adapter.
This connection simultaneously powers the control unit, illuminates the remote 
controls back panel and relays commands back to the projector.
To allow the operator more flexibility the remote control can be operated by four
AAA batteries, producing infra-red signals which are detected by sensors located at
the front and rear of the projector. The Remote Control unit is designed to transmit
command signals to the projector from a maximum distance of 80m (266ft).
Very bright fluorescent lighting or Infra Red translation systems may saturate the
projectors Infra Red receivers rendering remote control inoperative.
Palm Pilot Control Utility
The Palm Pilot Control Utility has been designed to allow extensive operational
control of the projector without using the on-screen menu system. The control 
program is designed to operate with the computer port of any LIGHTNINGdisplay
projector and is capable of controlling multiple (daisy-chained) projectors.
For information on operating the Palm Pilot Control Program refer to System
Operation, C—55.
There are other programs available for the Palm Pilot platform which provide for
full set-up and design, contact your Digital Projection dealer for further details.

							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 according to your individual requirements. However, to achieve 
optimum results we recommend a low gain (1.2 - 1.3), non-perforated screen for
front projection, this will keep hot spotting and light loss to a minimum whilst 
providing wide viewing angles. 
Regardless of the type of screen used, it is important that your screen is of sufficient
height to display the images at the aspect ratios intended to be used. Use the 
following tables to check that you are able to display the full image on your screen.
If you have insufficient height, you will have to reduce the overall image size in
order to display the full image on your screen.
