Scissor Lift SLX by Draper page 2 of 8 <br />www.draperinc.com (765) 987-7999 <br />Figure 2 <br />3/8"-18 x 1" hex head cap <br />screws for attaching Lifting <br />Cable Bar to Bottom PanAttachment points <br />for Lifting Cables <br />¼"-20 x ¾" hex head <br />cap screws for attaching <br />Projector Pan to Bottom Pan <br />Lifting <br />Cable Bar <br />Projector Pan <br />Bottom Pan <br />Hanging Unit <br />Please note: If using Environmental Air Space Housing option, go to Environmental Air Space Housing instructions on page 8. <br /> The Scissor Lift may be installed in a variety of ways; recessed above the <br />ceiling, or suspended below the ceiling. The lift should be supported by four ½" <br />threaded mounting rods or bolts with locking nuts. If ceiling recessed, the entire <br />unit (including the projector) should set approximately 1½" above the finished <br />ceiling in its “stored” position. The threaded rods should pass through the corner <br />mounting flanges and be secured by nuts above and below. The unit should then <br />be guy wired or blocked to prevent swinging. <br />All installations should observe the following guidelines: <br />1 If installing above a hard ceiling, optional Draper Access Panels are available to <br /> allow access to the unit. <br />2 Installer must ensure that all fasteners and supports are of adequate strength to <br /> securely support Scissor Lift and projector. <br />3 Fastening methods must be suitable for mounting surface, and securely <br /> anchored so that vibration or abusive pulling on unit will not weaken installation. <br />4 Unit should be level, with weight shared more or less equally by all four <br /> threaded mounting rods. <br />5 Bottom of unit must be unobstructed after installation. Sufficient clearance must <br /> be allowed below projector or optional ceiling closure. <br />6 Unit must be secured independent from suspended ceiling and do not use unit <br /> to support adjacent ceiling, light fixtures, etc. <br />7 Unit to be installed so when lowered to its lowest point, it is a minimum of 8 feet <br /> (2.44 m) above the floor. <br />8 Do not complete the ceiling below unit until electrical connections have been <br /> completed and unit has been operated successfully. <br />9 We recommend that safety cables be attached to the Scissor Lift SLX for <br /> added security (a sound installation practice with overhead equipment). <br />10 When the Scissor Lift SLX is to be installed in “other space used for <br /> environmental air” the optional environmental Air Space Housing must be installed per instructions to isolate the lift from the “other space used for environmental air.” <br />11 When Scissor Lift SLX is nOt installed in environmental air space housing and <br /> optional ceiling closure, the ALTERNATE wiring for 'UP' limit switch may be <br /> used. Disconnect both BLACK (BK) wires from 'UP' limit switch and quick <br /> connect them together using the provided jumper cable (see Alternate Wiring <br /> schematic on page 5). <br />Operation <br /> Before operating or testing the unit, make sure the packaging has been <br />removed from the unit. Remove the corrugated block from the cardboard sleeve <br />(bottom-most packaging material), then collapse the sleeve and remove it, along <br />with the rest of the packaging. Next, using the 3 button switched, operate the lift in <br />the "up" direction, so the lift's control encoder will recognize it's "home" location. <br />Until you do this, the Down function will not work. You must also do this if the Scissor Lift ever loses or is disconnected from the power. <br /> When unit is first operated, be cautious! If unit fails to operate properly, press <br />“StOP” and recheck electrical connections before proceeding. Cycle unit down <br />and up several times to confirm satisfactory operation. Caution: Do not pull on or touch safety belt when unit is in motion. If belt locks, the cables will unspool. <br /> Caution: Obstructing bottom pan may cause cables to unspool. Caution: Do not operate Scissor Lift SL without a minimum of 15 lbs. of <br />weight attached to the pan. Operating without weight may cause cables to unspool. <br />Standard Single Station Low Voltage Control (See Fig. 1)— <br />One three-button switch with “UP”, “DOWn”, <br />and “StOP” buttons. Lift starts up or down when <br />appropriate button is pressed, and may be stopped <br />by pressing “StOP” button. Factory set limit <br />switches stop lift automatically when projector is in <br />“show” position. One momentary key switch lowers <br />lift from “show” to “service” position. <br />Optional Multiple Station Control— <br />Optional, moves lift from “stored” to “show” position only. Each switching station has <br />a three-button switch with “UP”, “DOWn”, and “Off” buttons. Lift starts up or down <br />when appropriate button is pressed, and may be stopped by pressing “Off” button. <br />Factory set limit switches stop lift automatically when projector is in “show” position. <br />Optional Key Operated Switch— <br />If ordered, the standard Lift LV Switch can be replaced with a second single <br />station, momentary key-operated three position (up/off/down) switch. Multiple <br />Station Control required for this option. Moves lift from “stored” to “show” position <br />only. <br />Optional Infrared or Radio Frequency Remote Control—If ordered, a three- <br />button transmitter is provided, with “UP”, “DOWn”, and “StOP” buttons. Unit starts <br />up or down when appropriate button is pressed, and may be stopped by pressing <br />“Off” button. Factory set limit switches stop unit automatically when projector is in <br />“show” position. Only controls "show" and "stored" positions. <br />Optional RS232 Control—For Serial communication an R2D7 Serial <br />Communications Interface is optionally available. <br />Low Voltage Trigger—Input provided for Low Voltage Trigger from projector <br />(see diagram on page 4). <br />Please Note: Scissor Lift SLX must be installed in accordance with the requirements of the Local Building Codes, the Canadian Electrical Code (CEC), <br />CAN/CSA C22.1 and the National Electric Code (NEC), NFPA 70, as required. An appropriate disconnect device shall be provided as part of the building installation.Scissor Lift SLX is approved to UL 2442 and CSA C22.2 no. 60065-03. <br />Preferred Method—Adjusting Projector Pan <br /> The Projector Pan can be moved forward or back. <br />1 Make sure Bottom Pan is supported. <br />2 Remove the Lifting Cable Bar. <br />3 Remove screws holding Projector Pan on Bottom Pan. <br />4 Move Projector Pan forward or back. <br />5 Replace screws. <br />6 Replace Lifting Cable Bar. <br />Secondary Method—Adjusting Lifting Cable Bar <br />(if above does not work) <br />Run the unit to its "Service" position and make sure Bottom Pan is level. <br />Try and set so that bottom pan is not more than ¾" out of level. However, the pan does not have to be perfectly level, as long as the positioning is consistent and repeatable in "Show" and "Closed" positions. <br />1 Make sure Bottom Pan is supported. <br />2 Remove screws holding Lifting Cable Bar to the Projector Pan. <br />3 Move Lifting Cable Bar forward or back. <br />4 Replace screws. <br />5 Check level again. If still not level, repeat. <br />Adjusting for Level or Center of Gravity (See Fig. 2 Below) <br />Caution: <br /> Beware of pinch points <br />Caution: Beware of pinch points <br />2¾" <br />4½" <br />7/8" <br />Front Side Back <br />D C U <br />Lift LV Switch <br />Up & Show <br />UP <br />OFF <br />DOWNUPDOWN <br />OFF <br />SP-KSM <br />Service <br />Figure 1
