Up/Down and Swivel IR/RF Remote Control

It is critical importance that the installer fully reads and understands these
Instructions before installing or operating the lift.

LIFT-TECH’s IR/RF remote controller for a motorized up/down and swivel lift is
highly sophisticated and utilizes the latest computer chip technology to control the
lift’s functions. The controller consists of a black electronic box, and IR/RF remote
control.

For RF press and hold “Down” and “1”for three seconds. For IR press and hold

“Down” and “3” for three seconds.

Operation of the hand-held transmitter is very straightforward. There are seven
different buttons on the transmitter; an up arrow, a down arrow, a left arrow, a
right arrow, and three preset buttons. The up arrow button commands the lift to
raise. The left arrow button commands the left swivel function. The right arrow
button commands the right swivel function. The down arrow button commands the
lift to lower. If the lift is in a swiveled position when the down button is depressed,
the swivel will return to center and then lower. The three preset buttons are labeled
1, 2, and 3. They can be programmed by the operator to any 3 preset positions of
their choice. If the lift is lowered and a preset button is pressed, the lift will raise
and rotate to the corresponding preset position. If any of the buttons are pressed
with the lift raised, the swivel will rotate to the corresponding preset position. Once
again, if the lift is in a swiveled position when the down button is depressed, the
swivel will return center and then lower. The precision, reliability, and unique
operating features of this controller clearly sets it apart form and ahead of any
other in the marketplace.

Installation and Operating Instructions

If is of critical importance that the installer fully reads and understands these

instructions before installing or operating the lift.

When the lift is shipped from the factory, the swivel will be in center position. The
swivel function will not operate with the transmitter when the lift is in the lowered
position. The up/down functions will operate only when the swivel is in the center
position. If vibration in shipping has caused the swivel to be out of center, do not

rotate the swivel by hand. Use the manual override buttons on the control box to
return the unit to center.

LIFT-TECH utilizes a unique combination of computer chip technology and a
solenoid to establish absolute center for the swivel. A potentiometer provides
feedback to the controller so that the controller can determine the exact swivel
position. This feature is important for a number of reasons:

1. To establish absolute center, so that there is no “play” that might result in

damage to the cabinetry when the lift raises and lowers.

2. To establish a maximum range of swivel operation. The Custom

Television Lifts swivel will be shipped with a range of 180° in both
directions; however, the limits may be readily reprogrammed at any time
if less swivel travel is desired. This feature is beneficial for applications
in which less travel is desired to avoid hitting a wall or other obstruction
when swiveled too far. Once programmed, the controller will retain the
swivel limits or “soft stops” until reprogrammed.

3. To set the preset positions: The precise feedback from the potentiometer

ensures that the swivel always returns to the programmed preset position.

4. There are no external switches or magnets on the swivel. The use of the

potentiometer will provide reliable operation without having to worry
about magnet placement or switch adjustments. The controller will
actually identify that the swivel is approaching the “soft spot” and will
decelerate the swivel motor to ensure a smooth motion when stopping.

IR Receiver Mounting and Connections

The unit is designed to install in a ½” diameter hole and comes with a mounting

nut and lens. The lens unscrews to allow the tube to be easily inserted through the
back of the ½” hole. Once inserted, replace the lens and moderately tighten the
mounting nut. Use caution not to over tighten the nut.

An infrared system such as this requires a line of sight between the receiver and
transmitter. Therefore, care should be taken to ensure that the receiver placement
allows a line of sight to the infrared transmitter from normal operating position.

The infrared receiver needs to be plugged into the connection on the box labeled
IR EYE.

Set Up

1. Plug the connector into the electronic control box. There are three
connections to be made. The main lift cable is and eight pin Molex connector. It is
plugged it to the female connector on the box labeled LIFT. The main lift cable
provides power to the up/down motor and supplies power to the duplex receptacle
on the lift platform. ( For up/down lift only the LIFT connection should be
plugged in) The swivel cable has a twelve pin Molex connector. Plug it into the
female connector on the box labeled SWIVEL. The swivel cable provides power to
the swivel motor and the solenoid. In addition, it returns feedback to the control
cox from the potentiometers. Mount and connect the receiver as described previous
section. All connections are to be made prior to provident AC power. Plug the

power cord into a 115V AC receptacle last.

2. After powering the unit, wait 15 seconds before using the hand-held
transmitter. During this time, the controller is cycling through a learning mode.

This learning mode will be utilized if the lift needs to be reprogrammed; however,
it will retain the factory programmed settings in the absence of any input during
this cycle.

3. After waiting 15 seconds, the swivel is now in operating mode. If the AC
power source is interrupted, the controller will remember absolute center and
maximum swivel range as long as no input is made within 15 second cycle when
power is restored. If input is accidentally made, the swivel limits are easily
reprogrammed. If this occurs, follow the reprogramming instructions in the next
section or call LIFT-TECH.

During normal operation, the swivel always returns to the center position from a
clockwise position. This allows the proper engagement of the solenoid when
returning to absolute center. When the swivel is automatically returning to center
from a left swivel position, it will slightly overshoot center, reverse direction, and
approach the center (engaging solenoid contact to the physical stop) from the right.
