Limit Adjustments (Built-in Low Voltage Motors)

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.

1 Connect the ILT switch to the motor via the terminal blocks, or via the

modular port using four conductor modular cable. When using modu-

lar cable, the cable connectors MUST NOT be crimped in reverse, as

with standard telephone cable. (For a Dry Contacts Wiring Diagram,

see page 3.)

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 the desired upper limit by pressing and holding the UP button on

the 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.
