SAFETY SUMMARY
It is important for everyone involved in the installation and operation of the LiftMaster model BG
3000-B3 Barrier Gate Operator reads the following warnings.
WARNING!
• 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.
• Improper installation of a gate operator can result in a dangerous system.
• Gate operators can present serious hazards to persons in the immediate area when
not controlled in a safe manner. Choose one or more controls which 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.
• All controls must be kept out of the reach of small children. Serious injury or death
can result from children playing with the controls.
• All controls should be located so the person operating them can see the full area of
gate movement.
• Gate operators and associated control equipment should be installed by qualified
professional installers who should observe the following safe installation procedures:
1. Power should always be disconnected whenever installing, wiring or servicing a
gate operator. Moving chains and belts in gate operators can catch clothing or
fingers and cause severe injury.
2. Installation of wiring should comply with all local building and electrical codes.
3. 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.
4. All operator controls and safety equipment should be tested at the conclusion of
installation to be sure they are functioning properly.
5. 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.
6. Moving gates have pinch points and entrapment zones which can be extremely
dangerous to pedestrians, especially small children.

BASIC INSTALLATION HINTS AND RULES
PLEASE READ THIS SECTION CAREFULLY BEFORE BEGINNING YOUR INSTALLATION.
The sections that follow contain detailed procedures for installation of a model BG 3000-B3 system. In
addition to these specific procedures, there are a number of general hints and rules which will help
ensure that your installation will be done correctly and efficiently. These are discussed below.
1. UNDERSTAND THE SYSTEM AND INSTALLATION SITE THOROUGHLY. The BG 3000-B3 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. U.L. specifications require the BG 3000-B3 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. GROUND THE SYSTEM. The system contains parts which may be damaged by static discharge. A
proper earth ground connected to the gate operator housing (see Figure 3) 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.
4. 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/Slave system, Master and Slave must each have separate circuits (see the manual,
Installation and Operation, Master/Slave Systems for Series B3 Gate Operators).
5. DO NOT OVERLOAD THE TERMINAL BLOCKS. The terminal blocks used in the gate operator 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.
6. 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.
7. 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.
8. 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 lots of inconvenience and
aggravation later.

for Series B3 Gate Operators.
1. Always install the gate operator on the inside of the gate perimeter. NEVER install on the
public side of the perimeter.
2. All manual controls and activating devices should be mounted at least 6 ft. away from the gate
to provide safety.
3. Allow enough clearance around the gate and the gate operator for installation and service.
INSTALLATION NOTES
Rev E Doc 01-20206 (6001521) 3 of 36
B. PAD AND MOUNT
The concrete pad must be sufficient to support the gate operator and the dynamic forces
1.
created by the moving gate. LiftMaster recommends a pad 20” wide by 22” long by 20” deep.
2. 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. L-bolts 1/2” x 6“ are recommended.
3. The pad should be level and about 4” above grade to prevent water entrance. Allow concrete
to set at least two days before installing gate.
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, see Installation and Operation of Master/Slave Systems
for Series B3 Gate Operators.
NOTE: The only access area for the conduit stub is at the center of the pad, indicated as the
shaded area in Figure 2 Top View. Allow a minimum three-foot-long conduit stub.
Figure 2. Pad and Mount.
INSTALLATION NOTES
Rev E Doc 01-20206 (6001521) 4 of 36
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.
3. Wire Size/Length Requirement: comply with the local Electrical Code for operating a 1/2 HP
motor (suggest 12 AWG/up to 300’ and 10 AWG/up to 500’).
4. Be sure to pull a ground wire in the conduit for the connection to the gate operator. Do not rely
on metallic conduit for earth ground.
D. LOOP DETECTORS
1.
The gate operator has a shelf that can 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. Available shelf space: 13" x 7".
4. Wire Size/Length Requirement: 16-24 AWG stranded or 18-24 AWG solid wire/up to 3000’.
NOTE: Optional LiftMaster-supplied loop detector add-on boards are available, both pre-installed
and for installation in the field. See Part 4, BG 3000-B3 Options.
E. MASTER/SLAVE INTERCONNECTION (MASTER/SLAVE SYSTEM ONLY)
A conduit between the Master and Slave units should be provided for the Master/Slave
1.
interconnection cable.
2. Wire Size/Length Requirement: Two shielded twisted pair wire 16 AWG to 24 AWG/up to 3000’
will be connected between the two units through the conduit at TB1 on the controller board.
NOTE: Do not run the Master/Slave cable and AC power wires in the same conduit.
F. OTHER CONNECTIONS
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/Length Requirement: 16-24AWG stranded or 18-24AWG solid wire/up to 3000’.
G. 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 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 boards.

SYSTEM INSTALLATION
A. MOUNTING GATE OPERATOR
To avoid injury, always turn off the unit power switch before working on gate.
1. Mount the cabinet on the cement pad using the previously installed anchors. Be sure the
operator mounting is level and square, and that the gate operator access door faces away
from the driveway (see Typical Installation, Figure 1).
2. Slightly loosen the mounting screws of the control box clear plastic cover. Slide the
cover out.
3. Swing the control box open fully to allow connection of the conduits. Run the conduits
through the bracket in the lower back of the control box.
4. Cut excess conduit and use 90 degree conduit fittings to attach conduits to the control box.
Note: the input power conduit need not go through the bracket and can be attached to the
control box directly.
After attaching the conduits to the control box, make sure that: a) the conduits fold to the right
during control box closure; and b) the control box swings freely open or closed.

C. RUNNING INPUT WIRING
1. Run wires from input components and Master/Slave conduits into control box.
2. For Master/Slave wiring, refer to Installation and Operation of Master/Slave Systems for
Series B3 Gate Operators.
WARNING
Route but do not connect input wires at this time. If inputs are connected now, the gate operator
may activate at random during installation, potentially injuring installation personnel.
D. SETTING GATE OPEN DIRECTION SWITCHES S2 AND S3
Figure 4. Gate Direction & Option Switch Location.
1. Gate opening direction is set by switch S2, located on the control board. The switch is sensed
only on power up, so it should be set when the power is off.
2. Ensuring power is off, set switch S2 to the left if the cabinet access door faces away from the
driveway (typical installation), or to the right if the access door faces the driveway (restricted
installation).
3. Set S3 switch to the direction you wish the gate to move (open or closed) after a power outage
when LOW BATTERY input is activated by an Uninterruptable Power Supply (UPS). Switch
set to left: gate fully opens after power outage. Switch set to right: gate fully closes after
power outage.
E. POWER UP PROCEDURE
If gate is positioned at the 'open' limit, gate will automatically close if Reclose
Timer is enabled and power is switched on. Position gate either at the closed
limit or at no limit when preparing to switch power on. Always use extreme
caution and follow all warning in the Safety Summary.
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 5).
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 bottom. 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.
CAUTION
Rev E Doc 01-20206 (6001521) 7 of 36
F. USING MANUAL CONTROLS
Figure 5. Manual Controls, Location and Use.
If necessary, use the manual controls on Manual Input Terminal TB2 (OPEN, CLOSE, and STOP,
as shown in Figure 5), to move the gate arm during system installation.
• To open the gate: connect the OPEN and STOP terminals to the COMMON terminal.
• To close the gate: connect the CLOSE and STOP terminals to the COMMON terminal.
• To stop the gate: disconnect the STOP terminal from the COMMON terminal.
If the STOP terminal is disconnected from the COMMON terminal, the gate is prevented
from moving and no command will affect the gate.
