SAFETY SUMMARY
It is important for everyone involved in the installation and operation of the Gate Operator to
read the following warnings.
WARNING!
1. READ AND FOLLOW ALL INSTRUCTIONS. Improper installation of a gate operator
can result in a dangerous system. SAVE THESE INSTRUCTIONS.
2. A vehicle gate is a large, heavy object that is moved by an electric motor. A moving
gate can cause serious injury or death! The safety and well-being of others depends
on the installation of a safe system.
3. The entrance is for VEHICLES ONLY. Pedestrians must use a separate entrance.
Always keep people and objects away from the gate. NO ONE SHOULD CROSS THE
PATH OF THE MOVING GATE.
4. Choose one or more controls that together will allow complete control of the gate.
Most importantly, the gate must be able to be stopped at all times in case of
emergency, and the emergency control should be conveniently located, clearly
marked and visible.
5. All controls must be kept out of the reach of small children. Serious injury or death
can result from children playing with the controls.
6. All controls should be located so the person operating them can see the full area of
gate movement.
7. Use the emergency release only when the gate is not moving.
8. KEEP GATES PROPERLY MAINTAINED. Have a qualified person make repairs to the
gate hardware.
ꢀ
Test the gate operator safety features monthly. The gate MUST reverse on
contact with a rigid object or stop when an object activates the non-contact
sensors.
ꢀ
After adjusting the force or the limit of travel, retest the gate operator. Failure
to adjust and retest the gate operator properly can increase the risk of
damage, injury or death.
9. Gate operators and associated control equipment should be installed by qualified
professional installers who should observe the following safe installation
procedures:
ꢀ
Power should always be disconnected whenever installing, wiring or servicing a gate
operator. Moving chains in gate operators can catch clothing or fingers and cause
severe injury.
ꢀ
ꢀ
Installation of wiring should comply with local building and electrical codes.
All manual gate locks should be disabled to avoid damage to the gate or gate operator
should the lock become engaged after the operator is installed.
ꢀ
ꢀ
All operator controls and safety equipment should be tested at the conclusion of
installation to be sure they are functioning properly.
The operation of the gate controls and safety equipment should be reviewed with the
owner and/or end user of the automated gate system. They should also be informed
of the need to maintain control and safety equipment on a regular basis. Safety
equipment should be checked monthly to ensure it is working properly. All
installation manuals and safety information should be left with the owner.
ꢀ
Moving gates have pinch points and entrapment zones which can be extremely
dangerous to pedestrians, especially small children.

BASIC INSTALLATION HINTS AND RULES
READ THIS SECTION CAREFULLY BEFORE BEGINNING YOUR INSTALLATION.
1. UNDERSTAND THE SYSTEM AND INSTALLATION SITE THOROUGHLY. The SW
2000 is a flexible and reliable gate operator system, but the quality of service depends
directly on the quality of installation. Please read these instructions carefully and study the
applicable diagrams before planning your installation. In particular, understand any site
characteristics that may affect the system installation.
WARNING
2. INSTALL PERMANENT WIRING. UL specifications require the SW 2000 system to be
permanently wired. Refer to your local wiring code for specific information.
WARNING: Damage caused by faulty wiring is not covered by warranty.
3. U.L. OBSTRUCTION-SENSING REQUIREMENTS. To maximize safety, U.L. 325
standards require primary obstruction sensing (gate sensitivity to impact) and secondary
obstruction sensing (photo-sensors) be in operation at all times.
4. GROUND THE SYSTEM. The system contains parts which may be damaged by static
discharge. A proper earth ground connected to the gate operator housing at the lower left
grounding screw (see Figure 12) will significantly reduce the chances of damage or
improper operation. The shielding in the cables specified for all remote sensors and
controls should also be connected to earth ground at the controller end of the cable only.
To be effective, the ground connection must be made by running 12 AWG copper wire to a
good ground point (e.g., an electrical panel, a metallic cold water pipe that runs into the
earth, or a grounding rod at least 10 feet in length that is driven into the earth) within 12
feet of the system. Even if you have a good earth ground, you should try to discharge any
static before handling the circuit boards.
WARNING: Damage caused by static discharge and lightning is not covered by warranty.
5. PROVIDE POWER FROM A DEDICATED SOURCE. The outlet into which you connect
the Gate Operator should be wired to its own circuit breaker to reduce line noise and
minimize the risk of having other equipment interrupt system operation. In a Master/Slave
system, Master and Slave must each have separate circuits.
6. DO NOT OVERLOAD THE TERMINAL BLOCKS. The terminal blocks are removable and
the pins are soldered into the boards. To connect your wires, remove the "head" from the
correct terminals and loosen the screws. Insert the wire into the correct opening on the
front and tighten the screw until the wire is held firmly. When you have made all
connections for a given "head", plug it back onto the pins designated for that terminal
block.
Stranded wire must be between 16 and 24 AWG. Solid wire must be between 18 and 24
AWG. This is the total thickness measurement so, if you are putting two wires in, the
combined thickness must fall within this range. NEVER try to insert more than two wires
per terminal.
7. ENSURE GOOD CONNECTIONS. A light tug on the wire will tell you if the connection is
secure. When reconnecting system components, make sure all pins are straight on chips,
connectors, and terminal block heads.
8. READ THE MARKINGS CAREFULLY. The connection points are marked on the boards
clearly. Before making any connection, be sure to read the marking and check it against
the corresponding figure in these instructions.
9. TRAIN YOUR CUSTOMERS THOROUGHLY. Although customer responsibility is limited
to proper installation, the quality of service is determined by the care of system setup.
Ensure that the customer has a copy of this manual to guide them.

NOTES
•
•
Left Gate and Right Gate are determined by looking from inside the complex toward
the street.
Figure 1 shows a typical Bi-Parting gate in standard and compact installations.
1. Always install gate operators inside of the fence line, NEVER on the public side of
the fence.
2. Mount all manual controls and activating devices at least 6 ft. away from the gate
for safety.
3. Allow enough clearance around the gate and the gate operator for installation and
service.
B. PAD AND MOUNT
Figure 2. Pad and Mount.
1. The concrete pad must be sufficient to support the gate operator and the dynamic
forces created by the moving gate. LiftMaster recommends a pad 24” wide by 27”
long by 30” deep.
2. The operator must be level and parallel to the gate, so the pad should be level and
about 4” above grade to prevent water entrance.
3. Four anchor bolts are required to secure the gate operator to the pad. The
mounting holes in the gate operator are 5/8” in diameter. Red Head bolts ½” x 3½“
are recommended.
4. Be sure to provide access for wiring conduits. In Master/Slave systems, remember
to include conduit stubs for separate inputs (if any) and for the Master/Slave
connection cable between gate operators. For more information about
Master/Slave systems, see Master/Slave Systems for X3 Series Gate Operators.
NOTE: Shading indicates conduit stub access areas.

C. POWER WIRING
1. Provide a separate conduit stub for the AC power.
2. Each gate operator requires a 115 VAC 20 AMP single phase circuit
NOTE: Master and Slave units each require separate circuits to prevent false
overcurrent faults (see X3 Series Master/Slave Systems).
3. Wiring must comply with the local Electrical Code for operating a 1/2 HP motor. 12
AWG for up to 300' and 10 AWG for up to 500' long wire runs is suggested.
4. Be sure to pull a ground wire in the conduit for the connection to the gate operator.
NOTE: Do not rely on metallic conduit for earth ground.
D. LOOP DETECTORS AND PHOTO-SENSORS
1. A shelf is provided (10" x 11" x 18" high) to support non-LiftMaster loop detector
electronics. Power for the loop detector can come from the auxiliary 115 VAC plugs
in the gate operator or from the 24 VAC provided by the gate operator control board.
NOTE: The auxiliary plugs have power regardless of the unit power switch setting.
2. Conduit provisions should be made for the “loop” wire entrance to the loop detector.
3. Wiring should be 16-24 AWG stranded or 18-24 AWG solid.
NOTE: Optional LiftMaster-supplied loop detector add-on boards are available, both
pre-installed and for installation in the field. See Part 3, Gate Operator Options.
E. TELEPHONE CONNECTION
1. A conduit entrance into the gate operator should be provided for the telephone line.
2. A single twisted pair wire 18 AWG to 24 AWG, will be connected from the telephone
company termination block through the conduit to J9 on the control board. Polarity is not
important.
NOTE: Do not run telephone and AC power wires in the same conduit.
F. MASTER/SLAVE INTERCONNECTION (MASTER/SLAVE SYSTEM ONLY)
1. A conduit between the Master and Slave units should be provided for the Master/Slave
interconnection cable.
2. Two shielded twisted pair wire 16 AWG to 24 AWG will be connected between the two
units at TB1 on the controller board.
NOTES: 1. Do not run the Master/Slave cable and AC power wires in the same conduit.
2. Master/Slave interconnection cable should not exceed 3000' in length.
G. OTHER CONNECTIONS
1. Provisions should be made for conduit entrance into the gate operator for external
activation devices such as key switches, telephone entry systems, loops, etc.
2. Wire size requirement: 16-24 AWG stranded or 18-24 AWG solid wire should be used.
H. GROUNDING
1. The system contains parts which may be damaged by static discharge. A proper earth
ground connected to the gate operator housing will significantly reduce the chances of
damage or improper operation. The shielding in the cables specified for all remote
sensors and controls should also be connected to earth ground at the controller end of
the cable only.
2. To be effective, the ground connection must be made by running 12 AWG copper wire
to a good ground point (e.g., an electrical panel, a metallic cold water pipe that runs into
the earth, or a grounding rod at least 10' in length that is driven into the earth) within 12'
of the system. Even if you have a good earth ground, you should try to discharge any
static before handling the boards.

J. GATE SENSITIVITY ADJUSTMENTS
The gate operator monitors both average and peak motor current. When the gate
encounters an obstruction, the gate operator senses the change in motor current and
reverses the gate. Three sensitivity adjustments must be set for each installation:
•
•
•
Right gate motion (R69)
Left gate motion (R160)
Inrush current (R203)
NOTE: For swing gate operation, controls are Left/Clockwise and
Right/Counterclockwise.
♦ If your installation requires setting switch S2 to the “Open to Right” position, use
the “Open to Right" adjustment procedures below. If your installation requires
setting S2 to the “Open to Left” position, use the “Open to Left" adjustments
following the "Open to Right" procedures.
♦ The minimum sensitivity is full clockwise and maximum sensitivity is full counter
clockwise. These adjustments must be made while the gate is in motion.
♦ Before starting the adjustments, verify that the Left and Right reverse pots are set
fully clockwise, and the Inrush pot is set to the 11 o’clock position.
♦ Make all adjustments in the order listed.
NOTE: Current flow varies with temperature. Do not tune the sensitivity
measurements too finely, or they may cause false overcurrent faults to occur during
cold weather.
Figure 10. Gate Sensitivity Adjustments Location.
"OPEN TO RIGHT" ADJUSTMENT PROCEDURES
Right Gate Motion Adjustment (R69)
1. Initiate opening the gate.
2. Wait 4 to 5 seconds, then lightly "tug" against the edge of the gate to simulate an
obstacle.
3. If the gate does not stop or back up, reclose gate and adjust the pot slightly
counterclockwise.
4. Repeat steps 1-3 until gate stops or backs up when tugged and has the desired
sensitivity.

IMPORTANT: Before proceeding, see NOTES below.
1. Wire all external control devices to their connections on the control board as
shown. See Appendix A for details on how each control input affects the gate
operator.
2. Connect the Master/Slave interconnect cable (see Master/Slave Systems for X3
Series Gate Operators, Part 1).
NOTES
1. Disconnecting the STOP terminal from the COMMON terminal stops the gate and prevents all
commands from having any effect. Manual Open does not activate the Reclose Timer.
IMPORTANT: As per UL325 standards, install the Manual Input and Fire switches in the
line of sight with the gate.
2. If gate(s) are used for bi-directional traffic, the Exit Loop should be a directional loop detector.
3. Inside and Outside Interrupt Loops:
♦ For maximum safety, Inside and Outside Interrupt loops require separate loop
detectors.
♦ Bi-part or Bi-part Latch: If only one loop detector is used, connect Outside loop to the
Inside loop detector.
4. Battery is used to store date and time.

• IMPORTANT NOTE: SWING GATE BACKUP DISTANCES
Slide gates move at about one foot per second, so backup distances (Obstruction
Senses and Interrupt Bar Backup) are easy to enter. To move the gate one foot, you
enter 12 inches.
Swing gates, however, move in degrees per second, so it is the length of the gate that
determines how far the gate moves each second. For instance, a twenty foot gate will
move twice as far as a ten foot gate in the same amount of time. As a result, entering
backup distances for swing gates is different than for slide gates. Use the following
table to enter swing gate backup distances:

stops the gate.
2. Verify that Manual Close fully closes the gate and that the close limit switch
stops the gate.
3. Verify that Manual Stop stops the gate.
Note: If the gate stops due to an obstruction Fault, readjust the gate sensitivity
pots.
3. Mechanical
Use the Manual Input commands to verify that:
1. The gate swings open and closed smoothly.
2. There is no squeak or vibration in the gate when it is moving .
3. There is no belt slippage when the gate moves or stops.
4. There is no slack in the closed gate due to loose chain or parts.
5. Both gates open and close at the same time (Bi-Parting gates only).
4. Gate Sensitivity and Obstruction Alarm
(Primary Obstruction Sensing per UL 325 Requirements)
1. Left/Right Obstruction sensitivity:
Apply a bump to the opening and closing gate and verify that the gate stops or
reverses.
2. Start-Up Sensitivity:
Apply a bump to the gate as it starts moving and verify that the gate responds to
the bump within a second.
3. Obstruction Alarm:
Cause two obstruction faults before the gate reaches its open or closed limit
and verify that the Obstruction Alarm sounds.
5. Entry inputs

ꢀ
Test the Operator
Quick Reference List of Faults and Methods to Resolve
Quick Reference List of Faults and Causes
Testing Control Board inputs: To test an input, connect the input terminal to the
COMMON terminal on the Control Board and verify that its LED turns on
momentarily. Normally, the Close limit switch and Maglock LED's are on if the gate
is fully closed, and Open limit switch is on if the gate is fully open. The Manual
STOP LED is always on.
Low input AC voltage: The voltage across connector J1 pins 1 (red wire) and 3
(white wire) on the Control Board must measure 100VAC to 130VAC.
CAUTION HIGH VOLTAGE. Measure with care.
Fault Causes: Refer to the end of trouble shooting section.
1. OPERATOR IS DEAD
When the unit power switch is cycled, the 7-segment display does not spell
out "HELLO" sequentially.
1. The main circuit breaker or unit power switch is off.
2. The input power connector is not connected securely to the Control Board.
3. Low input AC voltage.
4. Bad Control Board.
2. OPERATOR DOES NOT RUN
When the unit power switch is turned on, the 7-segment display spells out
"HELLO" sequentially.
1. An input is continuously activated (stuck).
2. Both limit switches are stuck closed.
3. Manual Stop is disconnected from its common.
4. Stalled motor.
3. MOTOR DOES NOT RUN
Motor is dead:
1. The resettable motor thermal overload switch has popped.
2. The interconnecting cable between the motor and the control board is
disconnected.
3. Bad control board or motor.

D. MAINTENANCE
WARNING
To avoid injury, always turn off the unit power switch before working on gate.
Regularly performance of preventive maintenance is essential for reliable system
operation because it corrects small problems before they turn into emergencies.
LiftMaster recommends performing preventive maintenance every 6 to 12 months,
depending upon the amount of gate usage.
•
•
If the gate is installed in a private residence or small apartment house where
usage is not severe, yearly preventive maintenance is acceptable.
If the gate is installed in a high-traffic application, semi-annual preventive
maintenance is essential.
PREVENTIVE MAINTENANCE TASKS
1. Gate Arm: Check for wear in the moving parts. Check for hardware tightness.
2. Gate: must swing freely without any impediment. Check hinges, grease if
necessary.
3. Chain: Check for wear and tension. If loose, adjust tension with chain tensioner.
Do not oil chain.
4. Sprocket: must not be loose in the shaft. Tighten set screws if loose –.
5. Limit switches: contacts must bounce back rapidly when they are pressed and
released.
6. Belt: Check for wear and tension (25 to 30 lb.). Adjust the AC motor up or down
to set proper tension.
7. Pulleys: must all line up and be firmly secured to their shafts. Tighten set
screws if loose –.
8. Gear Box: Check for no oil leakage around the bushings. Do not oil gearbox.
9. Control board: Check for water damage or burned spots. All connectors
secured to the board.
10. Wiring: Check all wiring for any insulation damage. Check for loose wire
connections.
11. No Rust: Check for rust throughout the unit. Check corners for water
entrapment.
12. Fire Open: Activate Fire department switch to verify emergency gate opening.
13. Gate Sense: Check for the gate sensitivity (refer to Part 2, System Installation,
paragraph J, Gate Sensitivity Adjustments).
14. Photo-Sensors: Ensure that sensor emitters/receivers are aligned and clean.
Verify that inputs stop gate.
15. Obstruction Alarm: Check for proper operation. Alarm must sound after two
consecutive gate obstruction faults.
NOTES:
–: To prevent loosening, two set screws are used in each hole and Loctite
threadlocker 242 is applied.

FUNCTIONAL INPUTS
NOTES: – The term "activation" means closing an input circuit (via a relay or switch), and may
be momentary or continuous. Momentary activations are superceded by any
command. Continuous activations are superceded only by an overriding command.
— Activating any command when gate is at the open limit stops the Reclose Timer.
When the command (except Manual CLOSE and STOP) is cleared, the Reclose Timer
is reset.
MANUAL INPUTS: OPEN, CLOSE, AND STOP (TB2)
MAN OPEN
MAN CLOSE
MAN STOP
Activation fully opens the gate. Continuous activation holds gate
open. MAN OPEN overrides Anti-Tail-gate (ATG), Reclose Timer, and
all controls but MAN STOP.
Activation fully closes the gate. Continuous activation holds gate
closed. MAN CLOSE overrides all controls but MAN STOP, MAN
OPEN and FIRE.
De-activation stops opening and closing gates. MAN STOP overrides
Reclose Timer and all other controls, manual or automatic. If MAN
STOP is disconnected from its COMMON, no commands affect the
gate.
ENTRY SYSTEM/FIRE SWITCH INPUTS (TB9)
CYCLE
Reclose Timer disabled:
Alternate Action allows a single command to both open and close the
gate. Activation opens the gate, which remains open until another
command is received. A CYCLE command when the gate is fully open
closes the gate. CYCLE also opens a closing gate. If Anti-Tailgating
(ATG) is enabled, Alternate Action is disabled. With ATG enabled, the
gate begins closing as soon as the INTERRUPT LOOP clears.
Reclose Timer enabled:
Activation opens the gate, then the Reclose Timer closes the gate. A
CYCLE command also opens a closing gate, but will not close a fully
open gate if the Reclose Timer is enabled. If Anti-Tailgating (ATG) is
enabled, the gate closes as soon as the INTERRUPT LOOP clears.
FIRE
Activation opens the gate. Continuous activation holds the gate
open. If the Reclose Timer is disabled and FIRE is deactivated, the gate
closes after 5 seconds. If Reclose Timer is enabled, when FIRE is
deactivated, the Reclose Timer starts. FIRE overrides all commands but
Manual STOP.
EXIT LOOP/SHADOW LOOP DETECTOR INPUTS (TB10)
EXIT LOOP
Same as CYCLE, but does not close the gate when it is fully open.
SHADOW LOOP Activation prevents the gate from opening or closing so the gate won't hit
a vehicle. If the gate is already moving, or if the gate is not fully opened
or closed, this input has no effect.

ADJUSTMENTS
OBSTRUCTION
Adjustable pot controls gate sensitivity to blockages by the
instantaneous rise in motor current. When the limit is exceeded, the
gate stops and reverses a programmed distance (a minimum of 2
inches).
RIGHT (R69)
OBSTRUCTION
LEFT (R160)
Adjustable pot controls gate sensitivity to blockages by the
instantaneous rise in motor current. When the limit is exceeded, the
gate stops and reverses a programmed distance (a minimum of 2
inches).
NOTE: LiftMaster gate operators have two obstruction sense adjustments (left and
right) where other gate operators have only one. This allows greater
flexibility of installation. For instance, you can install a gate on an incline
and not worry about sacrificing downhill gate sensitivity.
INRUSH
(R203)
Adjustable pot controls the delay in sensitivity to gate
obstructions. This delay in sensitivity prevents the initial motor
inrush current from causing a obstruction fault. The weight of the
gate determines this setting.
CONNECTORS
LIMIT SWITCH (J4)
PWR INPUT (J1)
