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.

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. Engage idler end bracket (rectangular mounting pad) Retaining clip in the same manner as motor end bracket and slide Motor roller Washer it toward the opposite end of the unit housing. Do assembly not tighten set screws on this bracket until the roller/ Idler end roller background assembly is installed, and centered in case. 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. www.draperinc.com page 2 of 4 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.
