Draper LCD Lift Video Projector Installing Optional Ceiling Closure, Electrical Connections

220V LCD Lift by Draper

➄Access should be provided to electrical control box in case service is

required.

➅Do not use unit to support adjacent ceiling, light fi xtures, etc.

➆Do not complete the ceiling below unit until electrical connections have been completed and unit has been operated successfully.

➇We recommend safety cables be attached to LCD Lift for added security.

Electrical Connections

Unit operates on 220-240V AC, 50 Hz. current.

Opening electrical control box exposes terminals for fi eld connections. Unit is shipped with internal wiring complete and control switch(es) boxed. Wire connecting unit to switch(es) and to power supply should be furnished by installer. Connections should be made in accordance with wiring diagram, and wiring should comply with national and local electrical codes. All operating switches should be “off” before power is connected.

LCD Lift should be operated and checked prior to installing bomb bay doors, universal (fl at) ceiling closure or projector.

Operation

When unit is fi rst operated, be cautious. If doors or closure panel do not begin to open momentarily when switch is fl ipped “down”, return switch to “off” and free doors and/or recheck electrical connections before proceeding. Cycle unit down and up several times to confi rm satisfactory operation.

220 V Single Station Control (CE Approved)—3-position UP-OFF-DOWN switch permits operation to be stopped at any point. Factory set limit switches automatically stop lift when fully down or fully up.

220 V Multiple Station Control (Not CE Approved)—Switches are similar in appearance to Single Station Control. Lift stops when switch is released and may be restarted in either direction. Factory set limit switches stop lift automatically when fully up or fully down.

24 V Control (CE Approved)—Three-button UP-STOP-DOWN switches stop at any point desired, operate in any sequence. Factory set limit switches automatically stop lift when fully up or fully down. Wireless controls—whether infrared or radio frequency—interface with low voltage control box.

Key Operated Switching (Not CE Approved)—Two kinds of key-operated switches are optionally available with this unit.

➀The key-operated power supply switch controls power to the lift and switches. When it is “off”, the switches will not operate lift. Key may be

removed from the switch in “on” or “off” position.

➁A three-position key switch permits the lift to be operated directly by key. In this case, the lift’s operator must have a key.

Installing Optional Ceiling Closure

If your LCD Lift is equipped with an optional ceiling closure system, it can be used as is, or in conjunction with a piece of existing ceiling tile.

➀If installing with ceiling tile, you may need to cut tile so that its overall dimensions are the same as (or slightly less than) the closure panel. Place

tile into trim frame. Lay closure panel on top (back side) of ceiling tile, and tighten screws to hold in place.

➁If installing large closure, attach brackets to bottom of projector plate (see drawing at right).

➂Attach 5/16" threaded rods to slots in projector plate or brackets.

➃Run unit “up” until bottom pan stops at highest position. Mark position on 5/16" rods even with ceiling level and cut rods to length (removing from

pan if convenient).

➄Run unit “down” until bottom pan stops at “show” position.

➅Attach closure to lower end of 5/16" rods by slipping into four corner slots

and secure with nuts above and below slots.

➆Run unit “up” again to highest position. Measure distance by which panel

fails to reach required “closed” height for surrounding ceiling.

➇Run unit “down” then re-adjust mounting of 5/16" rods in traveling grid to raise panel required distance.

Caution: Make sure nuts are completely tightened.

➈Test unit operation to confi rm that panel will stop in closed position just

before touching ceiling.

Caution: DO NOT hang from, "ride" or pull down on the unit. This could create a failure and cause damage and/or injury.

NOTE: Immediately upon completion of the surrounding ceiling, unit should be operated to confirm that optional ceiling closure panel stops just short of touching ceiling in closed position.

Installing Bomb Bay Door Closure

➀Attach closure to LCD Lift frame with factory supplied hardware. Bomb bay doors should be hanging straight down.

➁Lower unit until traveling pan is approximately 10 cm above its lowest position.

➂Install supplied ball chain to connectors attached to the eye bolts threaded

into angles on traveling pan (See Fig. 2).

➃Install ball chain to connectors attached to bomb bay doors.

➄ Raise unit to highest position. Doors should close completely.

➅ If the doors do not close completely, lower unit and adjust the eye bolts until doors close completely.

➆ Once “closed” position has been accomplished, lock eye bolts into place with hex jam nuts.

➇ Adjust the LCD Lift to the height of the fi nished ceiling.
