PREPARATION
LDT, LDTB 3
Track Assembly
1. Using the center idlers and the front
idler, assemble the operator rail by install-
ing the idlers between the rails. Use the
hex nuts on the outside and fasten them
tight. The front idler should be installed in
the second hole. The center idlers should
be spaced evenly over the length of the
track.(Figure 1)
2. Slide the trolley carriage onto the rail
so that the emergency disconnect bracket
will be toward the operator.
Operator Attachment
1. Position the track assembly on the
frame of the operator so that the motor
side is in the back (away from the door).
2. Align the holes in the rail with the holes
in the operator and install four 5/16 bolts
(two per side).
3. Install hex nuts on the bolts and tighten
to secure the operator to the rail.
Chain Installation
1. With the trolley engaged in the chain tensioner, use a master link to attach one end of the chain to
the chain tensioner.
2. Route the chain around the front idler sprocket and the drive sprocket on the operator and back to
the other side of the chain tensioner. (Ensure the chain rides across the top of all center idlers pres-
ent)
3. Connect the free end of the chain to the chain tensioner using another master link.
4. Disengage the chain tensioner from the trolley using the emergency disconnect and slide the trol-
ley out of the way (Figure 2).
5. With the lock nut loose, tighten the chain by turning the main body of the chain tensioner. When
desired tension is reached, tighten the lock nut. (If necessary, remove links from the chain to achieve
proper adjustment.)

Wall Mount
Mounting Wall Mount
The trolley operator is generally mounted over
the center of the door. Some instances require
the operator to be off center. If mounting off
center refer to the door manufacturing for proper
lifting point. (Torsion spring doors may allow off
center lifting but Extension spring doors require
center lifting.)
1. Mark a vertical line on the header above the
door that is centered on the door.
2. Determine the highest point of door travel.
Slowly raise the door until the top section reach-
es its highest point. Use a level to project this
line to the header where you marked the center
of the door. (Figure 3)
3. Ensure the header is suitable to mount the
wall mount to. If necessary, reinforce the wall/
header with a mounting pad or suitable mounting
brackets.
4. Install the wall mount using suitable hardware.
The wall mount should be centered on the verti-
cal line that was drawn and 1"-2" above the line
that was drawn from the highest point of door
travel.
Mount Operator
1. Raise the front end of the rail assembly to the
wall mount and loosely install two 5/16 bolts and
nuts to act as pivot points.(Figure 4)
2. Swing the operator to a horizontal position and
temporarily secure it with suitable rope, chain, or
support from the oor.
3. Tighten the pivot bolts/nuts.
4. Slowly open the door being careful not to disrupt the temporary support.
5. With the door fully open, place a level on top of the rail and use shims across the top section of the
door to support the track assembly in a horizontal position.(Figure 5)
IMPORTANT NOTE: To aid installation, see page 17
(Shop Drawing) for mounting consideration.

INSTALLATION
Hang the Operator
1. The illustration shows a typical method of
hanging the operator from the ceiling. Each
installation may vary, but in all cases side
braces should be used for additional strength.
2. Clearance holes are provided on both
sides of the operator for mounting the support
braces.
3. With the rail in line with the wall mount,
install the appropriate support bracing. (If
the track is longer than 15' a middle support
brace is recommended). (Figure 6)
Door Attachment
1. Fully close the door.
2. Install the door bracket to the top section of the door and in-line with the rail using suitable hard-
ware. Many installations, except solid wood doors, will require additional support for the door. Refer to
illustration. (Figure 6)
3. Install the bottom hole of the curved arm to the door bracket using a 3/8-16 bolt, 3/8 lock nut, and
two 3/8 washers (tighten only enough to still allow arm to pivot.) The pivot bolt should be closely in-
line with the top rollers.
4. Slide the trolley so that the straight arm and curved arms holes line up. Use 5/16 bolts and nuts to
fasten the two arms tightly together. (The straight arm should angle away from the door 15-45 de-
grees)
NOTE: At this time, ensure all bolts and lags are properly secured.

SENSING EDGES
All types of sensing edges with an isolated normally
open (N.O.) output are compatible with your operator.
This includes pneumatic and electric edges. If your door
does not have a bottom sensing edge and you wish to
purchase one, contact the supplier of your operator.
If not pre-installed by the door manufacturer, mount the
sensing edge on the door according to the instructions
provided with the edge. The sensing edge may be
electrically connected by either coiled cord or take-up
reel.
ENTRAPMENT PROTECTION ACCESSORIES (OPTIONAL)
IMPORTANT NOTES:
a. Proceed with Limit Switch adjustments before
making any sensing edge wiring connections to
operator as described below.
b. Electrician must hardwire the junction box to the
operator electrical box in accordance with local
codes.
WIRING: For wiring of your sensing device to the operator,
refer to the wiring diagram supplied with your operator. See
eld connection terminals identied as Safety Device.
TAKE-UP REEL: Take-up reel should be installed 12” above
the top of the door.
COIL CORD: Connect operator end of coil cord to junction box
(not supplied) fastened to the wall approximately halfway up
the door opening.
LIMIT SWITCH ADJUSTMENT
1. To adjust limit nuts depress retaining plate
to allow nut to spin freely. After adjustment,
release plate and ensure it seats fully in
slots of both nuts.
2. To increase door travel, spin nut away from
actuator. To decrease door travel, spin limit
nut toward actuator.
3. Adjust open limit nut so that door will stop
in open position with the bottom of the door
even with top of door opening.
4. Repeat Steps 1 and 2 for close cycle. Adjust

To reduce the risk of SEVERE INJURY or DEATH:
• ANY maintenance to the operator or in the area near the operator MUST NOT be performed until
disconnecting the electrical power and locking-out the power via the operator power switch. Upon
completion of maintenance the area MUST be cleared and secured, at that time the unit may be returned
to service.
• DISCONNECT power at the fuse box BEFORE proceeding. Operator MUST be properly grounded
and connected in accordance with local electrical codes. The operator should be on a separate fused line
of adequate capacity.
• ALL electrical connections MUST be made by a qualied individual.
• DO NOT install ANY wiring or attempt to run the operator without consulting the wiring diagram. We
recommend that you install an optional reversing edge BEFORE proceeding with the control station installation.
• ALL power wiring should be on a dedicated circuit and well protected. The location of the power disconnect should
be visible and clearly labeled.
• ALL power and control wiring must be run in separate conduit.
• To avoid damage to door and operator, make ALL door locks inoperative. Secure lock(s) in “OPEN” position. If the
door lock needs to remain functional, install an interlock switch.
POWER WIRING CONNECTIONS
1. DO NOT INSTALL ANY WIRING WITHOUT
CONSULTING THE WIRING DIAGRAM.
The wiring diagram is included in this
manual (page 15).
2. Be sure the power being supplied is of
the correct voltage, phase, frequency, and
amperage in accordance with the operator’s
serial tag.
3. Using a conduit access hole as shown
below, bring supply lines to the operator and
connect wires to the terminals indicated on
the wiring diagram.
4. Important NOTE: Connect earth ground to

WIRING TYPE
LDT and LDTB models are equipped with the LX900
board (programing and operation, page 12, eld wiring,
page 16). Upon installation the operator will be in C2
mode (which means only constant pressure will close the
door).
To achieve B2 mode (where a momentary contact can be
used to close the door) an entrapment protection device
must be wired into the beam terminals according to the
wiring diagram. Once the LX900 detects there is no
obstruction it will switch to B2 Mode.
CONTROL STATION LOCATION
All operators are supplied with some type of control
station. Generally a three button station (OPEN/
CLOSED/STOP) is provided. Mount the control station
within sight of the door, at a minimum of ve (5) feet
above the oor so small children cannot reach it, and
away from all moving parts of the door.
RADIO CONTROL
All LDT series operators have internal antenna’s. LX900
compatible Single button, three button, or OPEN/CLOSE/
STOP (OCS) transmitter(s) are optional accessories.
While in B2 Mode, transmitters will operate the door the
same as a wall control station. Also on all LDT series
operators, terminal strip is provided on the side of the
electrical enclosure labeled as a 24 Volt Class 2 circuit
and numbered (1,2,3). All standard radio receivers
may be wired to this terminal strip. Single channel
transmitters will then open a fully closed door, close a
fully open door, and reverse a closing door from the radio
transmitter. However, for complete door control from a
remote, a commercial three-channel radio receiver (with
connections for OPEN/CLOSE/STOP) is recommended.
ADDITIONAL ACCESS CONTROL EQUIPMENT
Locate any additional access control equipment as
desired (but so that the door will be in clear sight of the
person operating the equipment), and connect to the
control board in accordance with the LX900 WIRING
CONNECTIONS diagram. Any control with a normally
open (N.O.) isolated output contact may be connected in
parallel with the OPEN button or to the momentary switch
terminals. More than one device may be connected in this
manner. Use 18 gauge wire or larger for all controls.
External Interlock Switch
If an external interlock switch is required on the door, refer to the LX900 WIRING CONNECTIONS diagram for installation.
This switch should have a contact rating of at least 3 amps @ 24VAC. The switch must be wired in series with the STOP
or COM terminals so that the door will only operate while the switch is in its closed circuit state.
To prevent possible SERIOUS INJURY or
DEATH from a moving garage door:
• ALWAYS keep remote controls out of
reach of children.
• NEVER permit children to operate, or
play with remote controls.
• Activate gate or door ONLY when it can be seen
clearly, is properly adjusted, and there are no
obstructions to door travel.
• ALWAYS keep gate or garage door in sight until
completely closed. NEVER permit anyone to cross
path of moving gate or door.
To prevent possible SERIOUS INJURY or
DEATH:
• Install the control station within sight of
the door at a minimum of ve (5) feet (to
prevent operation by children), but away
from the door and its hardware.
• Install reversing sensors when the 3-button control
station is out of sight of the door or ANY other control
(automatic or manual) is used. Reversing devices are
recommended for ALL installations
• A reversing edge MUST be installed when a receiver
is used to activate a commercial door opener.

PHOTO EYE INSTALLATION
1. Make sure that power is disconnected to the system prior to installing the photo eyes.
2. Photo eyes need to be mounted inside the building. They should be mounted on either side of the door and as close
as possible to the door track to offer maximum safety precaution.
3. Photo eyes should be mounted no more than 6 inches from the oor. Both brackets need to be installed at the same
height to allow them to align.
4. Select a mounting location 5 inches above the oor to the centerline of the wall mounting “L” bracket. Mount the
bracket to the wall. Repeat this step on the opposite side of the door.
5. Using the wing nuts provided, attach the photo eyes to the “L”
brackets with the arrows pointing up. Do not over tighten.
6. The transmitter and the receiver both have two 22-gauge wires
coming from them. Uncoil the wires from the photo eyes and route
them to the controller. Take one wire from the transmitter and one wire
from the receiver (these wires have no polarity) and twist the stripped
ends together. Repeat on the second wire from each unit. Connect the
wires to the BEAM terminals. Again, polarity is not important.
7. At this time, you can reconnect the power to the operator. The LEDs
on both transmitter and receiver will be lit if installed and aligned
properly; the transmitter has a red LED, and the receiver has a green LED.
8. If the photo eyes are not aligned, then the green LED on the receiver will be off. To align the photo eyes, you can
adjust the position of the transmitter or the receiver on the slot of the bracket until both LEDs are lit. Tighten the
brackets.
9. To test the photo eye system: open the door to the full open position. Close the door and as the door is closing,
obstruct the beam. The door should stop and reverse to open.
10. Test the photo eye’s function periodically.
PHOTO EYE INSTALLATION
IMPORTANT NOTE:
Identify which side of the garage door is exposed to the most
sunlight. Mount the sending unit (TX) on the side that is exposed
to the most sun. Sunlight may affect the photo sensors and this
orientation will help reduce the effect.

LX900 PROGRAMMING AND OPERATION
LDT, LDTB 11
MODES OF OPERATION
This controller has three (3) different modes of operation B2, C2, and TS (Timer Secure). Factory default is B2 mode and
the Timer To Close (TTC) is 0 seconds. Anytime the operator does not detect safety beams, it will automatically change to
C2 mode. If the TTC is larger than 0 seconds, it will automatically change to TS mode. There are 7 xed delays for TTC –
3, 15, 30, 45, 60, 90 and 180 seconds. To adjust the setting, hold in the TTC button (refer to diagram). Three LED's above
the TTC button will indicate the current setting on the adjacent chart. After reaching 180 seconds, it will jump back to 0
seconds (default) and the operator will revert to B2 Mode.
C2 Mode
• Momentary press of OPEN will open door.
• Constant pressure required on CLOSE for the door to close.
• Single or three button transmitter will open or stop the door only.
B2 Mode
• Momentary press of OPEN or CLOSE will activate door.
• Single button - reverses a closing door, stops an opening door.
• Transmitters activate operator same as wall stations.
TS Mode
• Button function is the same as B2 mode.
• Includes Timer to Close (TTC) function. The door will automatically close after set time expires. Timer starts when
door reaches the open limit. (When rst entering TS mode or after power interruption, momentary press of OPEN will
start timer if door is at OPEN limit.)
General Notes regarding Mode of Operations:
• After power interruption the rst move is Open.
• STOP button works in all modes of operation. If the 3 button wall station is not connected to the Control board or there
is no jumper between COM and STOP, the motor will not run.
• The Constant Pressure (CP) feature will work only from 3 and 1 button wired Wall Stations
• The controller includes a Run Timer: a maximum amount of time the motor will run after receiving either open or close
command. Factory default: 45 seconds. Not adjustable.
• Open override means that the door may be reversed while closing by activating an OPEN button without the need to
use the STOP button rst (for all 3 Modes).
To reduce the risk of serious injury or death, follow these instructions carefully:
• Read and follow ALL instructions.
• Keep ngers and other body parts away from all moving parts of the door and gate operator system
while it is being operated.
• Keep the radio controls away from children. Do not allow children to play with the controls.
• Keep away from the door when it is in motion. Watch the door while it is moving until completely
closed or opened.
• Do not cross the path of a moving door.
• Disable and locks and remove any ropes connected to the garage door to avoid entanglement and
prevent damage to the system.
• Do not make repairs to cable, springs, or other hardware; call a trained door systems technician. The system is
under extreme tension and can cause serious injury or death.
• Ensure that the door is properly operating and balanced. If not, call a trained door systems technician to make
repairs.

On model LDTB, a brake is supplied from the factory. It is
designed to stop and hold the door in position whenever power is
removed from the motor.
On rst installation the brake should not need adjustment. The
brake operation should be inspected every 3 months. As the
brake pads wear, adjustments need to be made to maintain
proper operation.
With the power disconnected to the
operator, carefully try to rotate the large
drive pulley by hand. The brake should
be engaged and it should be very
difcult to turn.
While pushing the solenoid plunger
in by hand, there should now be
