7 Do not seal unit in ceiling until electrical connections have been made and
unit has been operated successfully.
Caution
1 Read instructions through completely before proceeding; keep them
for future reference. Follow instructions carefully. Installation contrary to
instructions invalidates warranty. Care in mounting and correct operation
will mean long and satisfactory service from your Draper background.
2 Before removing unit from crate, check for damage and to make sure
all parts are included.
3 Allow enough access to remove cover should background become
damaged or should other service be required.
4 Unit should be installed level (using a carpenter’s level).
5 Nothing should be fastened to dowel or background.
6 Operating switch(es) is packed separately in carton. Do not discard with
packing material.
7 Unit operates on 110-120V, 60 Hz. 1.1 amp current draw.
NOTE: Unit has been thoroughly inspected and tested at factory and
found to be operating properly prior to shipment.
Electrical Connections
These instructions are meant as a guide only. They do not imply any responsibility
on the part of the manufacturer for improper installation or faulty workmanship at
the jobsite.
Hanging Screen
When locating background and checking clearance for operation, remember
background is centered in the length of the case. Regardless of mounting
method used, the following points apply:
1 Mounting brackets are shipped attached to the case. Engage each bracket
with top of housing as shown below and tighten set screws. A bracket
should be within 18" of each end of case. Brackets can be removed and
case mounted with lag screws through top of case (holes drilled on site).
2 Unit should be positively and securely supported so that vibration or even
abusive pulling will not weaken installation.
3 Installer must insure that fasteners used are of adequate strength and
suitable for the mounting surface chosen. Supporting hardware (chains,
cables, 3/8" rods, etc.) must be essentially vertical.
4 Entire bottom of case must be readily accessible after installation is
complete.
5 Front, back and top of case must be straight—not forced to warp or bow.
6 If case is painted on location, removal of roller/background assembly is
recommended prior to painting. If not removed, slot on bottom of case
should be shielded to protect background from paint splatters or overspray.
Remove
shipping
brackets
before
operating unit.
Unit operates on 110-120V, 60 Hz. current.
Junction box is located just above the bottom access panel at left end of unit
(standard, right end may be specified).
Remove the bottom access panel for access to the junction box cover. (See
Bottom Access Panel Removal instructions below). Remove four (4) hex head
screws that secure the cover to the junction box to expose the red, black, and
white pigtail leads and the green ground wire per wiring diagram on page 3.
If optional low voltage control or video interface control is specified and factory
installed, please refer to wiring diagrams on page 4.
Unit is shipped with internal wiring complete and control switch(es) fully
boxed. Wire to connect unit to switch(es) and switch(es) to power supply
should be furnished by installer. Connections should be made in accordance
with attached wiring diagram, and wiring should comply with national and
local electrical codes.
All operating switches should be “off” before power is connected.
Bottom Access Panel Installation/Removal

VCB Access/Series E Instructions by Draper
Motorized Roller/Fabric Installation
Please note: When ordering a motor with built-in Low Voltage Controller, if the
case ships separate from the "guts," the case includes the 25' cable and special
low voltage switch.
The bottom access panel must be removed first.
The motor end mounting bracket has a metal bracket with snap ring for accepting
motor head. Back out the four set screws in bracket until they are flush with top
side of bracket.
To engage the motor end bracket flange above the two
channels in the top of the screen housing, rotate the
bracket approximately 45° counterclockwise to allow the
top surface of the motor bracket to rest flat against the
top inside of the housing. Rotating the bracket clockwise
until it is engaged with the channels, slide it along the
length of the housing against the electrical junction box.

mounting bracket
Locate the black washer and retaining clip attached to
the instruction sheet.
Note: This step requires two people to perform
safely. Raise the roller/background assembly up into
the unit housing and engage the head of the motor
completely into the motor mounting bracket, making
sure the snap ring engages with the motor and that
the limit switch adjusting knobs are visible from the
bottom of the unit housing.
While supporting the idler end of the roller, slide the
idler end mounting bracket toward the roller. Insert
the roller pin into the nylon bushing on the idler end
mounting bracket.
The roller idler pin needs to go through the idler bracket
far enough to allow the washer and retaining clip to be
reinstalled on the pin.
Failure to replace the washer and retaining clip could
result in the separation of the roller from the brackets.
The roller/background assembly and roller brackets may need to be slid left or
right in the mounting channel of case to center fabric within screen case.
Securely tighten the set screws on roller mounting brackets.
Connect the electrical plug from the motor to the mating socket on the junction
box.
Reinstall the bottom access panel as previously described.
Motorized Roller/Fabric Removal
Reverse the instructions above “Motorized Roller/Fabric Installation” for removal of
the unit.
Operation
When unit is first operated, be cautious! Cycle unit down and up several times to
confirm satisfactory operation.
110-120V SINGLE STATION CONTROL—3-position UP-OFF-DOWN switch
permits operation to be stopped at any point. Factory adjusted limit switches
automatically stop screen when fully down or fully up.
110-120V MULTIPLE STATION CONTROL—Switches are similar in appearance
to 110-120V Single Station Control. Background stops when switch is released
and may be restarted in either direction. Factory adjusted limit switches stop
background automatically when fully up or fully down.
24V CONTROL—Three-button UP-STOP-DOWN switches stop at any point
desired, operate in any sequence. Factory adjusted limit switches automatically
stop background when fully up or fully down. Installer should incorporate an allpole disconnect in the fixed wiring.
KEY OPERATED SWITCHING—Two kinds of key-operated switches are
optionally available with this unit.  The key-operated power supply switch controls
power to the unit and switches. When it is “off”, the switches will not operate unit.
Key may be removed from the switch in either “on” or “off” position.  A threeposition key switch permits the unit to be operated directly by key. In this case, the
operator must always have a key.
RS232/ETHERNET—Serial communication and network communication optionally
available with wall switches, RF or IR remote.

Limit Adjustments (Standard/Quiet Motors)
Please Note: Background limits are factory set for optimum performance of
the unit. A procedure is outlined below for minor tweaks, but any adjustment
of these limits may negatively affect the flatness of the background and
could also void the warranty. Please check with Draper prior to resetting
limits.
CAUTION: Always be prepared to shut unit off manually when new
adjustment is being tested. Unit may be severely damaged if background is
allowed to run too far up or too far down.
CAUTION: Be sure all switches are in “off” position before adjusting limit
switches.
The motor limit screws are normally located on the audience left of the roller.
**Please Note: If the VCB Access is “Right Hand Motor” or “Waterfall”, the WHITE/
DOWN and YELLOW/UP limit screws are reversed. See graphic below.
"Down" Limit Adjustment
To Reduce Background Drop
1 Raise background about 1' above desired setting and turn off.
2 Turn the WHITE/DOWN limit screw clockwise (three screw turns = ½ roller
revolution).
3 Test by running background down and repeat steps 1 and 2 until desired
position is reached.
To Increase Background Drop
1 Run background to the down limit.
2 With the down switch on, turn the WHITE/DOWN limit screw counterclockwise (3
turns of screw equals ½ roller revolution) to increase drop.
3 Test by running background up about 1' and back down to new down limit.
4 Repeat steps 2 and 3 until desired position is reached.
"Up" Limit Adjustment
Background is Running Too Far Up
1 Lower background about 1' below desired setting and turn off.
2 Turn the YELLOW/UP limit screw clockwise (3 screw turns = ½ roller revolution).
3 Test by running background up.
4 Repeat steps 1 through 3 until desired position is reached.
Background Needs to Run Up More
1 Run background down about 1' and turn off.
2 With the up switch on, turn the YELLOW/UP limit screw counterclockwise (3
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
background is running up! This could damage the background.
