Installation guidelines
3-2 5975638 BARCOGRAPHICS 1209s 010797
Abbreviations used in the calculations and the drawings :
B = Distance between ceiling and top of the screen (Ceiling
mounted) or distance between floor and bottom of the screen
(Table mounted).
A = Correction Value, extra value to be added to B to obtain the
correct installation position (In some cases the A value can be
negative).
CD = Total distance between projector and ceiling (Ceiling mounted)
or total distance between projector and floor (Table mounted).
CD = A + B.
Ceiling Mounted : when the result is negative, enlarge the
distance between ceiling and top of the screen, mount screen
lower, until CD becomes zero or positive.
Table Mounted : when the result is negative, enlarge the
distance between floor and bottom of the screen, mount
screen higher, until CD becomes zero or positive.
SW= Screen width.
PD = Perpendicular distance between screen and projector's mount.
To obtain the right values, you can make use of the new option
included in the Installation Adjustment Mode to let the projector
calculate the parameters automatically. Please refer to Chapter 8 for
details.
Where to install the projector ?
To indicate a correct installation position it is necessary to know :
ρ The distance from projector to ceiling in case of Ceiling
mounted or the distance from projector to floor in case of Table
mounted;
r The distance from projector to screen.
To find the correct position for the projector, equipped with HD120
lenses, use the following formulas:
Optinal lenses : HD180 for SW between 3m and 4.2m and HD300
11.5 cm
green phospho
(4.5 inch)
Used phosphor width on the CRT faceplate (e.g. green CRT)
Mounting Configuration
Ceiling Mount
To install the projector in the Ceiling configuration, use BARCO'S
Ceiling Mount Kit (CM100) - Order Number R9827341 (with pulley)
or R9827342 (without pulley). Installation instruction is included
inside the kit.
Table Mount
BARCO offers a heavy-duty projection table with adjustable height
which allows the projector to be correctly positioned perfectly to the
installation requirements. Order Number - R9827740.
PD[inch] = 1.311 x SW[inch] + 13.029
A[inch] = 0.113 x SW[inch] - 11.098
In metric :
In inch :
PD[m] = 1.311 x SW[m] + 0.33
A[cm] = 11.3 x SW[m] - 28.188
ρ Install the projector water levelled in both directions
ρ Install the projector perpendicular to the screen
for SW between 2m and 8.8m
