Limit Adjustments (Built-in Low Voltage Motors)
Please Note: Screen limits are factory set for optimum performance
of the screen. Any adjustment of these limits could void the warranty.
Please check with Draper prior to resetting screen limits.
(Height adjustments are made from wall switch)
1
Connect the switch to the motor via the terminal blocks, or via the modular
port using four conductor modular cable. When using modular cable, the
cable connectors MUST NOT be crimped in reverse, as with standard
telephone cable.
2
Set the slide switch to the lower position. Press and hold the DOWN button
on the switch to move the viewing surface to the desired lower limit. If the
screen moves in the opposite direction, release the DOWN button and
press and hold down the STOP button for four seconds. This will reverse
the operation of the UP and DOWN switches.
3
Move slider switch into center position.Wait a couple of seconds.
Please Note: If you move the slider switch from down to up in one
motion it sets the two limits in the same position.
1
Set the slide switch to the higher position. Move the viewing surface to the
desired upper limit by pressing and holding the UP button on the wall
switch.
2
Return the slide switch to the center position to return to normal operation.
3
To set the viewing surface to an alternate format position, move the viewing
surface to the desired position and press the STOP button. Press and
hold STOP for at least three seconds to record the position.
Please Note: Pressing and releasing the UP button on the switch will move
the screen to its upper limit. Pressing and releasing the DOWN button will
move the screen to its lower limit.
While the motor is in motion, pressing STOP for less than two seconds will
stop the viewing surface at its present position.
Once the motor is stopped, pressing the STOP button will move the viewing
surface to its alternate format position.
Pressing and holding the STOP button, when the motor is at rest or in mo-
tion, for at least three seconds will record a new alternate format position.

Limit Adjustments (Standard Motors/Quiet Motors)
Please Note: Screen limits are factory set for optimum performance
of the screen. Any adjustment of these limits could void the warranty.
Please check with Draper prior to resetting screen limits.
(Height adjustments are made at the motor using white/yellow screws)
Tools needed: Flashlight, small flathead screwdriver/Allen wrench (4mm or
5
/
32
").
CAUTION: Always be prepared to shut screen off manually when new
adjustment is being tested. Screen may be severely damaged if viewing
surface is allowed to run too far up or too far down.
The motor limit screws are normally located on the audience left of screen
roller, and the viewing surface rolls off the back of the roller. If the viewing
surface is coming off the front of the roller (motor on left), or the motor is on
the audience right of the screen roller (with viewing surface rolling off the
back), reverse the following instructions.
"DOWN" LIMIT ADJUSTMENT
To Reduce Screen Drop
1
Raise screen surface about 1' above
desired setting and turn off.
2
Turn the DOWN limit screw clockwise
(three screw turns = ½ roller revolution).
3
Test by running screen down and repeat steps
1 and 2 until desired position is reached.
To Increase Screen Drop
1
Run screen to the down limit.
2
With the down switch on, turn the DOWN limit
screw counterclockwise (three turns of screw equals ½ roller revolution)
to increase drop.
3
Test by running screen up about 1' and back down to new down limit.
4
Repeat steps 2 and 3 until desired position is reached.
"UP" LIMIT ADJUSTMENT
Screen is Running Too Far Up
1
Lower screen surface about 1' below desired setting and turn off.
2
Turn the UP limit screw clockwise (three screw turns = ½ roller revolution).
3
Test by running screen up.
4
Repeat steps 1 through 3 until desired position is reached.
Screen Needs to Run Up More
1
Run screen down about 1' and turn off.
2
With the up switch on, turn the UP limit screw counterclockwise
(three turns of screw equals ½ roller revolution).
3
Repeat steps 1 and 2 until desired position is reached.
CAUTION: Do NOT allow the dowel to wrap up over the roller when the
screen is running up! This could damage the screen.
