Targa and Premier—Large Sizes by Draper
Draper's Tab-Tensioning System is factory-set, and under normal circumstances will not require field adjustment.
If, however, you notice wrinkles, waves or other indications that the tensioning cables need to be adjusted, follow the procedure below.
1 Determine which side requires adjustment.
2 Secure dowel with one hand.
3 Using Phillips-head screwdriver, depress spring-loaded adjustment screw and slowly turn CLOCKWISE TO INCREASE tension,
or COUNTER-CLOCKWISE TO RELEASE tension. The screw adjusts in ¼ turn increments. Adjust only one increment (¼ turn) at a time
4 If problem is not corrected, leave screen in position for 24 hours to allow surface material to stretch into position.
5 If problem still is not corrected, repeat steps 2 and 3.
Caution: Do not touch
or bend surface.
Limit Adjustments (Standard/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.
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.
Adjusting "fully up" position —You should never have to adjust this
limit! If you do, however, the "Up" stopping position may be adjusted by turn-
ing the yellow limit switch adjustment socket. The yellow socket is located on
left end of screen roller and is accessible to a screwdriver/Allen wrench (4mm
or
/
"). Turning the socket counterclockwise will allow the viewing surface to
5

retract farther into the case. Turning it clockwise will cause the surface to stop
farther out of the case. One full revolution of the socket will alter the stopping
position of the viewing surface by approximately 1½".
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 screwdriver/
Allen wrench (4mm or
/
"). Turning the socket counterclockwise will allow the
5

viewing surface to run farther down. Turning it clockwise will shorten the view-
ing 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.

To access the Built-In LVC-IV
1 Remove the two (2) Torx head
screws from the motor end of

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.
CAUTION: Always be prepared to shut screen off manually when new
adjustment is being tested. Screen may be severely damaged if viewing

CAUTION: Be sure all switches are in "off" position before adjusting limit
switches.
(Height adjustments are made from wall switch)
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.
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.
