Limit Switch Adjustments
CAUTION:
Be sure all switches are in “off” position before adjusting limit switches
Always be prepared to shut lift off manually when new adjustment is being tested.
Limit switches for the AeroLift 100/150 are preset at the factory. The “Up” (closed) limit
switch is set for fully closed. The “down” (show) limit switch is set for fully lowered.
Once unit is in place, the “down” limit switch may need to be changed to stop the
AeroLift 100/150 closer to the ceiling (that is, to raise the “down” position). Limit
switches are located on the end of roller, and are accessible by removing the cover
of the junction box at the left end of the unit. To adjust the limit switches, use a

screwdriver/allen wrench.
Hanging Unit
The AeroLift is provided with four (4) mounting angles for suspending or direct mounting the unit from above, or direct mounting from the sides. These angles
provide up to 1½" of adjustment (side to side). The unit should be guy wired orblocked to prevent swinging. All installations should observe the following guidelines:
1
Installer must ensure that all fasteners and supports are of adequate strength to securely support AeroLift 100/150 and projector. It is recommended that
hardware structure be able to hold at least four times the combined weight of the lift, projector, housing, closure and ceiling material attached to closure.
Caution: DO NOT hang from, "ride" or pull down on the unit. This could create a failure and cause damage and/or injury.
2
Fastening methods must be suitable for mounting surface, and securely anchored so vibration or abusive pulling on unit will not weaken installation.
3
Bottom of unit must be unobstructed after installation. Sufficient clearance must be allowed below projector or optional ceiling closure.
4
Do not use unit to support adjacent ceiling, light fixtures, etc.
5
Do not complete the ceiling below the unit until electrical connections have been completed and unit has been operated successfully.
6
Use slots on the projector plate and on the closure to adjust the unit to ensure proper alignment of ceiling closure relative to ceiling opening.
Operation
When unit is first operated, be cautious! If unit fails to operate when the switch
is flipped “down”, return switch to “off” and re-check electrical connections
before proceeding. Cycle unit down and up several times to confirm satisfactory
operation.
110-120V Single Station Control
3-position up-off-down switch permits operation to be stopped at any point. Factory
adjusted limit switches automatically stop AeroLift when fully down or fully up.
Optional 110-120V Multiple Station Control
Switches are similar in appearance to 110-120V Single Station Control. AeroLift
stops when switch is released and may be restarted in either direction. Factory
adjusted limit switches automatically stop AeroLift when up or fully down.
Optional 24V Control
Three-button up-stop-down switches stop at any point desired, operate in any
sequence. Factory adjusted limit switches automatically stop AeroLift when fully up
or fully down.
Optional Infrared or Radio Frequency Remote Control
If ordered, a three-button transmitter is provided, with “up”, “down” and “stop”
buttons. Unit starts up or down when appropriate button is pressed, and may be
stopped by pressing “off” button. Factory set limit switches stop unit automatically
when projector is in “show” position. Multiple Station Control required for this
option.
Optional RS232/Ethernet
Serial communication and network communication optionally available with wall
switches, RF or IR remote.
Optional Key Operated Switching
Two kinds of key-operated switches are optionally available with this unit.
1
The key-operated power supply switch controls power to the AeroLift 100/150
and switches. When it is “off”, the switches will not operate lift. Key may be
removed from the switch in either “on” or “off” position.
2
A three-position key switch permits the AeroLift 100/150 to be operated directly
by key. In this case, the screen’s operator must always have a key.

Testing the Safety Limit Switches
The AeroLift 100 and 150 are equipped with two Safety Limit Switches
(see
"AeroLift—Limit Switch Adjustment (Bottom View)"
diagram on page 3).
These switches may be damaged during shipping or by rough handling on the
job site.
Once the AeroLift has been installed in the ceiling, but
before the projector and closure are attached, the Safety
Limits must be tested.
Use a screwdriver or other tool to press and hold the limit switch. While holding
down the limit switch, have someone operate the unit.
If the unit runs up while
the limit switch is depressed, the limit switch is broken and must be re-
placed
. Operating the unit without a functioning Safety Limit Switch could cause
the unit's motor to continue operating after the lift is closed, leading to a failure
and the possibility of damage or injury. Make sure to test BOTH switches.
Please Note: As weight is applied to the AeroLift, the projector plate may
shift slightly. If this occurs, use setscrews on bottom of fabric roller brack-
ets to compensate for shift and level projector plate (see page 3).
