Please Note: Screen limits are factory set for optimum performance of the
screen. A procedure is outlined below for minor tweaks, but any adjustment of
these limits may negatively affect the flatness of the screen surface and could
also void the warranty. Please check with Draper prior to resetting screen limits.
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.
CAUTION: Be sure all switches are in "off" position before adjusting limit
switches.

1 Connect the ILT 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.
(For a Dry Contacts Wiring Diagram, see page 4.)
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.
4 Set the slide switch to the higher position. Move the viewing surface to desired
upper limit by pressing and holding the UP button on wall switch.
5 Return the slide switch to the center position to return to normal operation.
6 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 the STOP
button 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 the STOP button 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
motion, for at least three seconds will record a new alternate format position.
