Section 8.2 - ILT Motors with Internal Low-Voltage Control Limit Adjustments
(Fig. 12)
1.
Connect ILT switch to motor via terminal blocks, or via
modular port using a four conductor modular cable. When
using modular cable, cable connectors MUST NOT be
crimped in reverse, as with standard telephone cable.
(For Dry Contacts Wiring Diagram, see Section 12.)
2.
Set slide switch to lower position. Hold DOWN button to
move viewing surface to desired lower limit. If screen moves
in opposite direction, release DOWN button and hold STOP
button for 4 seconds. This reverses operation of UP and
DOWN switches.
3.
Move slide switch into center position. Wait several seconds.
Please Note:
Do Not
move slide switch from DOWN to UP
in one motion. This will set limits in same position.
4.
Set slide switch to higher position. Move viewing surface to
desired upper limit by holding UP button on wall switch.
5.
Return slide switch to center position to resume normal
operation.
6.
To set viewing surface to alternate format position, move
viewing surface to desired position and press STOP button.
Hold STOP button for at least 3 seconds to record position.
Please Note:
Press and release UP
button on switch to move screen to
upper limit. Press and release DOWN
button to move screen to lower limit.
• While motor is in motion, press
STOP button for less than 2
seconds to stop viewing surface at
present position.
• Once motor is stopped, press
STOP button to move viewing
surface to alternate format position.
• Hold STOP button, when motor is
at rest or in motion, for 3-5
seconds to record new alternate
format position.
• Hold STOP button for 3-5 seconds
while in programming mode to
reverse motor direction.

Section 8.1.1 - "Down" Limit Adjustment
(requires
5/32
" (4 mm) Hex key)
To Reduce Screen Drop:
1.
Raise screen surface approximately 1'
(30 cm)
above desired setting
and turn off.
2.
Turn DOWN
(I)
limit screw clockwise
(3 screw turns =
1/2
roller revolution)
.
3.
Test by lowering screen. Repeat steps 1 & 2 until desired position
is reached.
To Increase Screen Drop:
1.
Lower screen to down limit.
2.
With down switch on, turn DOWN
(I)
limit screw counterclockwise
(3 screw turns = 1/2 roller revolution)
to increase drop.
3.
Test by raising screen approximately 1'
(30 cm)
then down to new
down limit.
4.
Repeat steps 2 and 3 until desired position reached.
Section 8.1.2 - "Up" Limit Adjustment
If Screen Raises Too High:
1.
Lower screen surface approx. 1'
(30 cm)
below desired setting and turn off.
2.
Turn UP
(II)
limit screw clockwise
(3 screw turns = 1/2 roller revolution).
3.
Test by advancing screen up.
4.
Repeat steps 1 through 3 until desired position is reached.
If Screen Needs to Raise Higher:
1.
Lower screen surface approx. 1'
(30 cm)
below desired setting and turn off.
2.
With UP switch on, turn UP
(II)
limit screw counterclockwise
(3 screw turns =
1/2
roller revolution)
.
3.
Repeat steps 1 and 2 until desired position is reached.
CAUTION:
DO NOT allow dowel to wrap over roller when operating screen!
This could damage screen.
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.
Please Note:
If screen is “Right
Hand Motor,” the WHITE/DOWN
(I)
and YELLOW/UP
(II)
limit
screws are reversed
(Fig. 11)
.
CAUTION:
- Be sure all switches are in “off”
position before adjusting limit
switches.
- Be prepared to shut off manually
while testing.
- Screen may be damaged by
lowering it too far and
exposing roller.
- Motor must be installed so that
limit switches are pointed down.
