tion to be stopped at any point. Factory adjusted limit switch es au to mat i cal ly
stop screen when fully down or fully up.
220V Multiple Station Control
(Not CE approved)—Switches are similar
in ap pear ance to 220V Single Station Control. Screen stops when switch

Key Operated Switching
(Not CE approved)
—
Two kinds of key-operated
switches are op tion al ly available with this unit.
①
The key-op er at ed power
sup ply switch controls power to the screen and switches. When it is “off ”,
the switches will not operate screen. Key may be re moved from the switch in
either “on” or “off” position.
①
A three-po si tion key switch per mits the screen
to be operated directly by key. In this case, the screen’s operator must always
have a key.
RS232/Ethernet—
Serial communication and network communication
optionally available with wall switches, RF or IR remote.
Adjustments
Screen has been factory set and should not nor mal ly require further ad just-
ment. However, if you desire to change the “up” and “down” stop ping positions,
proceed as follows:
CAUTION:
Be sure all switches are in “off ” position before ad just ing limit
switches. Always be pre pared to shut screen off man u al ly when new ad just-
ment is being tested. Screen may be se vere ly dam aged if viewing surface is
al lowed to run too far up or too far down.
Adjusting “fully up” position —
“Up” limit switch, located im me di ate ly
above left end of automatic trap door, is tripped as door closes. If door does
not close fully, limit switch should be raised slightly. If door closes too tightly,
switch should be lowered slightly.
Remove steel plate attached to threaded neck of “up” limit switch by removing
hex nut securing it. Removing plate exposes three Phillips head ma chine
screws which hold limit switch bracket in place. Turn ing these screws clock-
wise will raise limit switch; turning them coun ter clock wise will lower it.
Raise switch only in quarter-turn increments. When operating prop er ly auto-
matic trap door should close gently and rest against but not press on rubber
bumpers above it. Adjusting automatic door so that it closes too tightly will
damage screen.
Adjusting “fully down” position —
“Down” stopping position may be ad-
justed by turning the white limit switch adjustment socket. The white socket is
located on the left end of screen roller and is accessible to a screw driv er/Allen
wrench (4mm or
5
/
32
") when automatic trap door is open. Access is easier
when bottom board is also open. (Do not adjust the yellow socket which is
next to and in back of the white socket). Turning the white socket coun ter-
clock wise will allow the viewing surface to run farther down. Turning it clock-
wise will shorten the viewing surface, causing it to stop in a less extended
position. At no time should viewing surface be unrolled enough to expose any
part of screen roller.

Hanging Screen
General:
When locating viewing surface and checking clear ance for screen’s op er a tion,
remember surface is centered in case. Screen is normally recessed above
ceil ing and may be installed in a varie ty of ways. See typical in stal la tion
detailed on back of this sheet. Re gard less of mounting method used, the
following points apply:
①
Screen should be lifted into position
only by the mounting brackets.
Keep case level by lifting both ends simultaneously to prevent
surface damage. Never attempt to lift screen along its length.
②
Screen should be positively and securely sup port ed so that vibration or
even abusive pulling on viewing surface will not weaken in stal la tion.
③
Installer must insure that fasteners used are of adequate strength and
suitable for the mounting surface chosen.
④
Entire bottom of case must be readily accessible after installation is
complete.
⑤
Hinge on bottom board and particularly hinge on automatic trap door of
screen must be per mit ted to operate freely. Front and back of case must
be straight—not forced to warp or bow. Hinges must be free from mas tic
or paint buildup, and doors must be un ob struct ed by ceiling tiles.
⑥
Do not use screen case to support adjacent sections of ceiling.
⑦
If trim pieces must be attached to case, do not permit screws to pro trude
through 19 mm (¾") wall of case. Do not attach trim with nails.
⑧
If case is painted, slots around doors should be shielded to protect
viewing surface from paint splatters or overspray.
⑨
Do not seal unit in ceiling until electrical connections have been made
and screen has been operated successfully.
