SVS TL1 Lift Installation Instructions Page 4 of 16

IMPORTANT: PLEASE READ THROUGH ALL INSTRUCTIONS (INCLUDING ACCESORY

INSTRUCTIONS) BEFORE BEGINNING YOUR INSTALLATION.

This lift is designed to be used with a Wall Plate Controller, either automatically or manually controlled and will
function without any special training in the “Show” mode. The Wall Plate Controller features a key switch
which can be placed in the “Show” or “Auto” positions for normal operation. The “Off” position disables the
Lift. The “Service” position must be used only by trained technical personnel when the Lift is lowered to floor
level for service/access.

Note: The “Auto” position on the Wall Plate Controller is for Accessory #4 Power Sensor, Accessory #5 Power
Sensor with Screen Control, and Accessory #15 12-Volt Trigger only

WARNING

To prevent personal injury and property damage when servicing any part of the Lift drive system (electric
motor/brake, drive chain/sprockets, steel lift cables, and/or drum lock assembly) the projector must be

removed and the Lift's lower frame supported by straps, chain, or cable to prevent it from lowering
unexpectedly while the drive system is being serviced.

IMPORTANT

If an Accessory #2 Plenum Shroud is to be installed with the Lift. Please read the Accessory Installation
Instructions before beginning your installation. The Lift support structure will need to allow enough space to
install the mounting hardware for the Plenum Shroud.

TO AVOID CABLE SPILLS

• Do not push the Lift bottom frame upwards once the lift has been installed.

• Make sure that there are no obstructions in the Lifts path. If the bottom frame is lowered onto an

obstruction the cable will slack and spill over the cable drum.

4. PRELIMINARY INSTALLATION CHECKS

• SVS recommends that the Lift support structure holds at least four (4) times the weight of the Lift and

projector combined. You should always follow your local building codes.

• Required space for the Lift, projector, and accessories should be considered prior to installation. Check

for obstructions that may prevent the Lift or accessories from being installed or operated.

• Plan for necessary Lift low voltage control cabling, projector audio/video/control cabling, and power

connections.

• Do not install the projector on the Lift until the Lift, hardware, and any accessories have been properly

installed and are operational.

• This Lift has been adjusted with cables tightly packed on the cable drum and leveled for precise tracking

prior to being shipped from the factory. Do not remove the lift's shipping blocks until instructed to
do so in Section 7. SVS scissor lifts are shipped in a slightly open position to eliminate stress on the
limit switches and to maintain a tight cable pack on the cable drum. If physical height measurements are
taken before the blocks are removed from the Lift, they may not accurately reflect the height of the
closed Lift.

• All weight attached to the Lift must be centered between the Lift's cables. The balance point of the

projector should be placed in line with the Lift cables (+/- 1-inch). If this is not possible you may need to
counter weight the Lift to keep the Lift level.

• For ease of installation the Lift can be hoisted into the ceiling location with blocks and tackle, or by

using a ratchet puller.

SVS TL1 Lift Installation Instructions Page 5 of 16

• As a reminder, clear all persons and obstructions from the Lift's path during its operation. Keep fingers

and other objects away from the scissors and other moving parts. Technical personnel should always be
present whenever the Lift is in the Service mode.

5. CONSIDERATION FOR LIFT PLACEMENT

• Before beginning the installation, check the dimensions of the Lift and the projector to be mounted

below the Lift against the available space above the ceiling. Be sure to include the lens and any
accessories which may add to the overall dimensions

• Preliminary measurements should also be made to layout the orientation of the projector and Lift to the

screen. Consider if the lens is offset from the center of the projector and thus the center of the Lift.

Figure 2. TL1-45 Front & Side Views

6. LIFT SUPPORTING STRUCTURE

The TL1 Lift should be mounted from four 3/8” rods
spaced at 13.5-inches (34.3cm) wide by 16-inches
(40.6cm) deep. The mounting hole locations are
marked with a [M] in Figure 3. The thread rods must
be supported by a rigid structure. If the threaded rods
exceed more than 2-feet (0.6 M) from the support
structure to the Lift's top mounting holes cross bracing
should be installed between the support rods. Figure 4
shows the cross bracing and the correct height for
mounting the Lift above the false ceiling.

If the ceiling clearance allows, an “X-Y” or a cross­supporting structure is strongly suggested (as shown in
the suggested supporting structure drawings in the
Appendix). This allows for front-to-back and side-to­side adjustments of the Lift for alignment to the screen.

Figure 5a. Flat Ceiling Support Structure

SVS TL1 Lift Installation Instructions Page 7 of 16

Figure 5b. Beam Ceiling Support Structure

Important

When attaching the lift to a flat concrete ceiling, SVS suggest two (2) pieces of P1000T Unistrut (or equivalent)
approx. 10-feet (3.04 m) long, to be installed on the ceiling first. Proper spacing between the two pieces will be
based on the distance between the four (4) mounting holes of the lift as shown in Figure 3.spaced at 20.5-inches
(52cm) wide by 16.75-inches (42.5cm) deep.

You should use at least four (4) 1/2” bolts and anchors evenly spaced on each piece of Unistrut to distribute the
weight of the supporting structure. Attach the two lower pieces of Unistrut to the upper two pieces of Unistrut
using 1/2” threaded rods to the Unistrut, using Unistrut P3010 1/2” channel nuts in the channel, along with a
locking washer and nut below the channel to lock into place.

IMPORTANT
If an Accessory #2 Plenum Shroud is to be installed with the lift. Please read the Accessory Installation
Instructions before beginning your installation. The lift support structure will need to allow enough space
to install the mounting hardware for the Plenum Shroud.

SVS TL1 Lift Installation Instructions Page 8 of 16

7. LIFT INSTALLATION

a. Preparation:

1. The Lift is shipped in a wooden crate.

2. Do not remove the Lift from the crate until you are ready to install it.

3. The Installation Instructions, Wall Plate Controller with control cable, and projector mounting hardware
are located in a cardboard box inside the crate.

4. Unbolt the Lift from the bottom of the crate to remove the Lift from the crate.

b. Installing the Lift in the Ceiling

1. Raise the Lift into the ceiling and line up the four (4)
mounting holes in the Lift's top frame with the 3/8”
threaded rods of the supporting structure. Make sure that
there is a top nut and a flat washer on each threaded rod
before the Lift is mounted. See Figure 5. (Plenum

Shrouds require additional hardware installed on the
threaded rods before the Lift.)

2. Once the Lift's top frame has been inserted, add a hexnut
to each threaded rod below the Lift frame. Always leave
the top nut loose to allow adjustments until the Lift is

Figure 6. Lift Mounting Hardware

leveled.

3. Level the Lift's top frame side-to-side and front-to-back using the lower hexnuts on the threaded rods.

4. Once the Lift is leveled, secure the Lift to the threaded rods by tightening the upper hexnuts. Do not
over tighten the fasteners as it could distort the top frame of the Lift.

5. If the Power Sensor is used, please refer to the Power Sensor Instructions, otherwise, plug in the 12-pin
connector of the Wall Plate Controller into the 12-pin socket on the Lift's gray electrical box mounted on
the rear of the Lift. The Wall Plate Controller includes 75-feet of cable and is shipped with the Lift. It is
located in the cardboard box attached to the lid of the Lift's shipping crate.

6. Once the Lift is properly installed in the ceiling and leveled, you can remove the shipping blocks.
Remove the blocks by removing the screws and tie-raps holding them in place.

TO AVOID CABLE SPILLS

• Do not push the Lift bottom frame upwards once the Lift has been installed.

• Make sure that there are no obstructions in the Lift's path. If the bottom frame is lowered onto an

obstruction the cable will slack and spill over the cable drum. If the cable spills over the cable
drum and the Lift is not stopped the cable will back-wind onto the cable drum causing severe
damage to the Lift and accessories.

SVS TL1 Lift Installation Instructions Page 9 of 16

8. ELECTRICAL CONNECTIONS

Electrical connections should be made at this time. The TL1 Lift requires 110V/60Hz at .66 Amps and is
supplied with a six foot power cord. The TL1 Lift is controlled with a 24VAC Low Voltage Controller called the
Wall Plate Controller. This controller can easily be connected to external controllers like Crestron, AMX,
Extron, etc. The Wall Plate Controller is supplied with 75-feet of cable (22 AWG, 9 conductor).

1. Make sure that the area below the Lift is clear and that all cable are clear of the Lift.

2. Apply power to the Lift by plugging it into an AC Outlet.

3. Before lowering the Lift attach some weight to the bottom of the Lift in order to keep the Lift's cable
tight on the drum until the projector is installed. Both cables are placed on the drum so that they start
unwinding from the outside to the inside of the drum. They are vertical to the eye bolts in the closed
position.

a. How to use the Wall Plate Controller

1. To lower the Lift to the Show position, turn the key switch to the Show
position and press the toggle switch down. The lift will lower as long
as you hold the toggle switch down, the lift will stop when the rear
scissor roller compresses the Show Position microswitch.

2. To lower the Lift to the Service position, turn the key switch to the
Service position and press the toggle switch down. The Lift will lower
as long as you hold the toggle switch down, the Lift will stop when the
rear scissor roller compresses the Down Limit microswitch. The
Service position bypasses the Show Position microswitch.

3. To raise the lift press the toggle switch up. The Lift will rise until the
Up Limit microswitches are compressed. The Lift will rise as long as
you hold the toggle switch up. The Lift can be raised with the key
switch in either the Show or Service positions.

4. The Off position on the key switch disables the Lift.

5. The Power light on the Wall Plate Controller only comes on when the
Lift is raising or lowering (Lift motor turning), not when power is
applied to the Lift.

Important: The toggle switch on the Wall Plate Controller must be pressed to
raise or lower the Lift, releasing the toggle switch stops the Lift. This is
designed as a safety feature. The key switch is an extra precaution, when the
key is removed, the Lift is secured.

WALL PLATE CONTROLLER

Controller (External Controller)

The simplest external controller
connections are to use the White wire as
the common, the Brown wire for down to
Show position and the Red wire for up.
For this and other wiring options please
refer to the external controller wiring
diagrams in the Appendix. Also:

1. Program a release of relays to
stop the Lift on up and down
positions

2. Program a time out after the
normal runtime, 2 seconds max.
(SVS Lifts raise/lower at 1­inch/second.)

3. Program an exclusive lockout on

Figure 8. Wall Plate Controller Wiring

up and down so that both cannot be activated at the same time. (Note: SVS Lifts have a lockout function
that disables the Lift when it receives a up and down command at the same time. Removing one of the
two commands resets the lockout.)

4. Hold relays on to raise/lower the Lift.

5. Never leave voltage on the up and down. Always program a release after the travel time has been
achieved.

If you have any questions, please contact SVS for proper wiring.

9. ACCESSORY INSTALLATION

Please refer to the accessory installation instructions located in the accessory shipping crates for specific
instructions for each accessory. The Accessory #2 Plenum Shroud and Accessory #12 Decorative Cover require
hardware be added to the threaded rods supporting the Lift before it is installed. The Accessory #1 Ceiling
Closure and FP1 Closure Panel attach the bottom Frame of the Lift using supplied threaded rods.

10. MOUNTING THE PROJECTOR

After checking the Lift operation and all clearances you can install the projector on the Lift. The projector can
be installed using a ceiling type projector mount (inverted) or using an Accessory #13 Metal Platform (non­inverted). For custom mounting option please contact SVS, Inc.

• The Projector can be attached to the Lift using an Accessory #9 Projector Mount from SVS or a standard
ceiling type projector mount. The projector mount is required to attach the projector to the Lift. The base
box of the projector mount will need to be bolted to the Lift. The mount should be centered side-to-side
with the Lift Frame. See Figure 9.

• If a ceiling type projector mount is not available for the projector or if the projector needs to be non­inverted, the projector can be placed on an Accessory #13 Metal Platform. The Accessory #13 Metal
Platform is a shelf mounted below the Lift to support the projector.

• All weight attached to the lift must be centered between the lift's cables. The balance point of the
projector should be placed in line with the lift cables (+/- 1-inch). If this is not possible you may need to
counter weight the lift.

SVS TL1 Lift Installation Instructions Page 11 of 16

Figure 9. Projector Mounting

Leveling the Projector

• If the projector can not be leveled using the projector mount adjustments, you can make fine adjustments
to the Lift.

• Level corrections are made with the projector mounted after confirming that the cable is packed tightly
and is straight on the Cable Drum.

• It is best to lower the lift to the Service position and then completely up before leveling the projector.

• Level adjustments should be made with the projector in the Show position.

• Position a level across the front of the projector. Fine adjustments are done by adjusting the nuts on the

bottom of the cable eye bolts. Raise and lower the Lift until satisfactory level is achieved.

• After adjustments are made tighten the eye bolt nuts.

11. CABLE MANAGEMENT

The SVS TL1 Lifts all feature cable retainers installed on the scissors extensions in the rear of the Lift. These
retainers are used to keep the projector cables clear of the Lift's moving parts during Lift operation. It is not
recommended attaching the projector cables to the scissors of the Lift as they could get repeatedly pinched
when the Lift raises and lowers. To keep the projector cables clear of the scissors please attach the cables as
show in the Figure 10.

SVS TL1 Lift Installation Instructions Page 12 of 16

Figure 10. Cable Management

12. SETTING THE SHOW POSITION

The Show position is adjusted by positioning the Show
position microswitch located on the rear right of the Lift's
top frame so that the large roller washer compresses the
Show position switch when the Lift reaches the Show
position.

1. Place the key switch in the Service position and
lower the Lift to the desired Show Position.

2. Loosen the thumb screw holding the Show
microswitch (bracket) in place and slide the Show
microswitch (bracket) along the Lift frame until
the large roller washer compresses the
microswitch. You should hear a slight click as you
position the microswitch over the washer and the
microswitch is compressed.

Figure 11. Show Position Adjust

3. Moving the Show microswitch toward the rear of
the Lift raises the Show position and moving the Show microswitch toward the front of the Lift lowers
the Show position.

4. Tighten the thumb screw. Make sure that the microswitch is not positioned too close to the washer
because the washer must be able to pass under the microswitch to reach the Service position.

5. The Show position is now set. Raise the Lift to a closed position and place the key switch in the Show
position and press the toggle switch down. The Lift will lower and stop at the Show position you set. It
maybe necessary to repeat steps 1 through 3 to get the Show position set where you want it.

6. The Lift will only stop at the Show position when lowering from above the Show position and not when
rising from below the Show position.

7. The Show position is adjustable with an accuracy of +/- 1/8-inch (0.32 cm).

SVS TL1 Lift Installation Instructions Page 13 of 16

13. MAINTENANCE

• Inspect the Lift occasionally for any loose bolts or cable clamps. The scissor bolts are adjusted for no
slack, but must not be too tight. If scissor bolts are found loose, tighten to approximately 151 lbs torque,
the back off 1/8-inch. These bolts have nylon locking nuts and should stay at this position.

• Check Lift and projector cables for damage or wear.

• That the Drum arm is being held up by the Drum Lock Spring.

• Check the Drum Lock pawl (white nylon piece) located on the Cable Drum. The pawl should move

freely and drop when when it reaches the top of the Cable Drum's rotation, avoiding contact with the
Drum Lock arm. If the drum rotates too fast, the pawl will swing out and catch the arm, locking the
drum after the first rotation.

• The Cable Drum Bearings (pillow block bearings) are pre-lubricated and do not require attention.

• The Lift motor does not require attention.

• If the magnetic brake (part of the Lift motor) does not hold properly, it should be replaced immediately.

WARNING

To prevent personal injury and property damage when servicing any part of the lift drive system (electric
motor/brake, drive chain/sprockets, steel lift cables, and/or drum lock assembly) the projector must be
removed and the lift's lower frame supported by straps, chain, or cable to prevent it from lowering
unexpectedly while the drive system is being serviced.
