SAFETY SUMMARY
It is important for everyone involved in the installation and operation of the Gate Operator to read the following
warnings.
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 SW2000 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, UL325 standards require
primary obstruction sensing (gate sensitivity to impact) and secondary obstructions 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 14) 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. This will reduce the line noise introduced into system
power and minimize the risk of having other equipment interrupt system operation. In a master/second
system, master and second 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 open
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 so that you understand the connection you are making.
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. It will save you and them a lot of inconvenience and
aggravation later.

LOCATION AND LAYOUT
Figure 1. Gate Operator Layout Options
SITE PREPARATION
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.
8
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. Concrete anchoring bolts 1/2" x 3-1/2" are recommended.
4. Be sure to provide access for wiring conduits. In systems, remember to include conduit stubs for
separate inputs (if any) and for the Master/Second connection cable between gate operators. For
more information about Master/Second systems, see Master/Second Systems for B3 Series Gate
Operators.
NOTE: Shading indicates conduit stub access areas .
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.

POWER WIRING
OTHER CONNECTIONS
LOOP DETECTORS AND PHOTO-SENSORS
MASTER/SECOND INTERCONNECTION (MASTER/SECOND SYSTEM ONLY)
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 Second units each require separate circuits to prevent false overcurrent faults
(see B3 Series Master/Second 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.
1. A shelf is provided (13” x 10” x 9” 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 Model SW 2000-B3 Options.
1. Provisions should be made for conduit entrance into the gate operator for external activating devices
such as key switches, telephone entry systems, loops, etc.
2. Wire size requirement: 16-24 AWG stranded or 18-24AWG solid wire should be used.
1. A conduit between the Master and Second units should be provided for the Master/Second
interconnection cable.
2. Two shielded twisted pair wire 16-24 AWG will be connected between the two units at TB1 on the
controller board.
NOTES:
1. Do not run the Master/Second cable and AC power wires in the same conduit.
2. Master/Second interconnection cable should not exceed 3000 feet in length.
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.

If the STOP terminal is disconnected from the COMMON terminal, the gate is prevented from moving and
no command will affect the gate.
USING MANUAL CONTROLS
Figure 6. Manual Controls, Location and Use
1. Turn on circuit breaker that provides power to gate operator.
2. On Manual Input Terminal TB2, connect the STOP terminal to the COMMON terminal (see
Figure 14).
3. Turn on gate operator power switch and verify that the row of LEDs on the right side of the controller
board all turn on, then turn off sequentially, starting from the top. The only LEDs that should remain
on are Power ON, MAGLOCK, and CLOSE LIMIT or OPEN LIMIT, if one of the limit switches are
engaged.
NOTE: If the LEDs do not follow this pattern, the controller board may not be working correctly. Stop
installation and call LiftMaster Technical Support for assistance.
4. On Manual Input Terminal TB2, disconnect the STOP terminal from the COMMON terminal.

GATE ARM INSTALLATION
NOTES:
1. All dimensions are measured from one pivot point to the next pivot point.
2. The dimensions shown above are only recommended settings. Your installation may require
different dimensions.
3. The SW2000-B3 can be installed without welding. The anchor, swing arm and drag link may be
attached using the supplied hardware only, may be welded, or bolted and welded.
4. Paint or other anti-rust coating must be applied to the cut areas of the swing arm and/or drag link
pipe to prevent rust.
1. Attach gate anchor to gate by welding or using hardware (not supplied).
2. Using manual controls, move the swing arm cap assembly until it points roughly to the anchor. See
Figure 7.
3. Measure and cut the swing arm to length. Attach swing arm to swing arm cap assembly with gate
stop on driveway side, using supplied hardware or by welding.
WARNING: Installing gate stop on the wrong side will cause damage to the gate operator.
4. Measure and cut Drag Link pipe to length, then insert spherical rod end assembly into pipe and
tighten locking nut.
5. Attach welded end of Drag Link Assembly to Anchor and unwelded end to Swing Arm.

SETTING LIMIT CAMS
• Adjust the limit cams by loosening the clamp and rotating the cams. The cams rotate with the swing
arm shaft, so small adjustments are magnified by the length of the gate.
• To avoid damage to the gate and gate operator due to the gate overrunning its limits, perform the
following steps carefully:
Figure 8. Setting Right Gate Limit Cam
1. SETTING RIGHT GATE LIMIT CAMS
1. Make sure that switch S2 is set to the “Right” position.
2. Turn on gate operator power switch.
3. Using manual CLOSE and STOP, move the gate to its proper closed limit position.
4. Loosen the clamp on the bottom limit cam and turn the cam clockwise until it just barely closes the
limit switch.
5. Retighten the clamp. Do not overtighten.
6. Using manual OPEN and STOP, move the gate to its proper open limit position.
7. Loosen the clamp on the top limit cam and turn the cam counterclockwise until it just barely closes
the limit switch.
8. Retighten the clamp. Do not overtighten.
9. Open and close the gate to check the limit cam settings. If required, readjust the limit cams until they
are set properly.
