SAFETY SUMMARY
It is important for everyone involved in the installation and operation of the LiftMaster model BG 3000-X1
Barrier Gate Operator to read 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 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 the installation of a model BG 3000-X1 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. UNDERSTA ND THE SYSTEM AND INSTALLATION SITE THOROUGHLY. The BG 3000-X1
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-X1 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 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 aMaster/Slave system, Master and Slave must each have separate circuits. See Installation and
Operation of Master/Slave Systems for Series X1 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 the 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 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 set up. 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.

B. PAD AND MOUNT
Figure 2. Pad and Mount
1. T he concrete pad must be sufficient to support the gate operator and the dynamic forces
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 ½” X 6” are recommended.
3. T he 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 X1 Gate Operators, Document Number 6001376.
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.
INSTALLATION NOTES
Rev CDoc 6001288 (01-20285)5 of 39
Page 10
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. Wiring must comply with the local Electrical Code for operating a ½ HP motor (suggest 12 AWG for
up to 300’ and 10 AWG for up to 500’ long wire runs).
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. The shelf space provided is approximately 7” x 6” x 32” high. Shelf space on systems without the
Power Fail Operation Option is about 12” x 6” x 32”.
4. Wiring should be 16-24AWG stranded or 18-24AWG solid.
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-X1 Options.
E. TELEPHONE CONNECTION
• A conduit entrance into the gate operator should be provided for the telephone line.
• 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 controller 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)
• A conduit between the Master and Slave units should be provided for the Master/Slave interconnection
cable.
• Two shielded twisted pair wire 16 AWG to 24 AWG will be connected between the two units at TB5 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 feet in length.
G. OTHER CONNECTIONS
• Provisions should be made for conduit entrance into the gate operator for external activating devices
such as key switches, telephone entry systems, loops, etc.
• Wire size requirement: 16-24 AWG stranded or 18-24 AWG solid wire should be used.

SYSTEM INSTALLATION
A. MOUNTING GATE OPERATOR
WARNING
For safety reasons, the Power Fail Operation Option is shipped with the battery unconnected to
the system. Do not connect the battery until all other installation and alignmentprocedures have been completed. Failure to observe this warning may result in the Power Fail
Operation Option moving the gate at unexpected moments.
To avoid injury, always turn off the unit power switch before working on gate.
WARNING
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.
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.
B. CONNECTING POWER
Ensure that the AC power circuit breaker is turned off before wiring power to the switchbox.
Run power cables through the conduit to Gate Operator, then connect wires to the switch box (see
Figure 3).
1. Wire nut the hot (black) wire to the black pig tail.
2. Wire nut the neutral (white) wire to the white pig tail.
3. Wire nut the ground (green) wire to the green pig tail.
4. Dress all wiring inside the switch box and install cover.
CAUTION

Rev CDoc 6001288 (01-20285)7 of 39
Page 12
C. RUNNING INPUT WIRING
1. Remove the plastic control box cover.
2. Run wires from input components and Master/Slave conduits into control box.
3. For Master/Slave wiring, refer to Installation and Operation of Master/Slave Systems for X1 Series
Gate Operators, Document Number 6001376, Parts 1 and 2.
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 S1 AND S2
Figure 4. Gate Direction, Power Fail Option Switch Location.
1. Gate opening direction is set by switch S1, 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 S1 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).
If the system was ordered with the Power Fail Operation option:
3. T he power failure gate opening direction is set by switch S2, located next to switch S1 on the
control board. Set switch S2 to left to fully open (Fail Safe) or to right to fully close (Fail Secure)
the gate during power outage (typical installation).
E. POWER UP PROCEDURE
1. T urn on the circuit breaker that provides power to gate operator.
2. T urn on gate operator power switch and verify that the seven-segment LED display above the
keypad sequentially spells out “HELLO”. The only LEDs that should remain on are 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 boar d may not be working correctly. Stop
installation and call LiftMaster Technical Support for assistance.
Rev CDoc 6001288 (01-20285)8 of 39
Page 13
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.
IMPORTANT NOTE
If the STOP terminal is disconnected from the COMMON terminal, the gate is prevented from
moving and no command will affect the gate.
G. GATE ARM INSTALLATION
Figure 6. Gate Arm Installation.
1. ARM FABRICATION
1. Use 1” x 6” clear pine or redwood (not supplied).
2. Cut arm to the desired length (up to 12 feet), then taper to dimensions shown in Figure 6.
Tapering the arm reduces weight and reduces warping.
3. Using the arm clam p as a template, drill four ½” diameter holes in the wide end of the arm.
4. Finish the arm using an exterior grade paint. Add striping with paint or tape.
Rev CDoc 6001288 (01-20285)9 of 39
Page 14
CAUTION
The total weight of the gate arm must not exceed ten (10) pounds. The lighter and/or shorter the gate
arm, the longer the life of the gear reducer and motor.
2. ARM ATTACHMENT
1. Secure hub flange to the output shaft with two set screws and the key from accessory kit.
2. Alig n the holes in the gate arm with the attachment holes on the hub flange and arm clamp.
3. Install and tighten the four supplied hex bolts, lock washers and hex nuts (see Figure 6).
NOTE: Make sure the arm clamp is oriented as shown in the figure.
H. GATE ARM ADJUSTMENT FOR TYPICAL INSTALLATION
Although preset at the factory, the turnbuckle may have to be adjusted to ensure the gate arm is level. If
required, adjust the turnbuckle as follows:
1. Make sure the unit power switch is off.
2. Rotate the gearbox pulley by hand until the crank arm is parallel with the turnbuckle shaft at its
lowest point of travel (see Figure 7).
3. If the gate arm is not level, loosen both turnbuckle jam nuts and rotate the shaft until the gate arm is
parallel with the ground, then retighten the two jam nuts.
Figure 7. Gate Arm Adjustment.
I. LIMIT CAMS
Gate operator limit cams are factory adjusted for 90 degree arm swing and are not to be adjusted in the field
except during limit cam or limit switch bracket replacement.
Rev CDoc 6001288 (01-20285)10 of 39
Page 15
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 stops or reverses the gate. Three
sensitivity adjustments are factory-set for most installations:
•Right gate motion (R69)@ 11:00 o’clock
•Left gate motion (R160)@ 11:00 o’clock
•Inrush current (R203)@ 9:00 o’clock
If your installation requires different sensitivity adjustments, use the following procedures:
♦ For Typical Installation, set switch S1 to “Open to Left” position and use the “Typical Installation”
adjustment procedures below. For Restricted Installation, set S1 to “Open to Right” position and use
the “Restricted Installation” adjustment 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 9 o’clock position (see (Figure 8).
IMPORTANT: Current flow varies with temperature. Do not tune the sensitivity measurements too
finely, or they may change with the time of day or seasons.
2. Wait 1 to 2 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 the gate and adjust the pot slightly
counterclockwise.
4. Repeat steps 1-3 until the gate stops or backs up when tugged and has the desired sensitivity.
“Left Reverse” Adjustment (R160)
1. Open the gate fully, then initiate closing the gate.
2. Wait 1 to 2 seconds, then lightly ”bump” the leading edge of the gate to simulate an obstacle.
3. If the gate does not stop or back up, reopen the gate and adjust the pot slightly
counterclockwise.
4. Repeat steps 1-3 until the gate stops or backs up when bumped and has the desired sensitivity.
3. INRUSH CURRENT ADJUSTMENT (R203)
1. Turn the pot fully counterclockwise.
2. In it iate opening the gate.
3. If the gate stops due to a fault condition, slightly adjust the pot clockwise.
4. Repeat steps 2 and 3 until the gate cycles without a fault.
5. Open the gate fully, then initiate closing the gate.
6. If the gate stops or backs up due to a fault condition, slightly adjust the pot clockwise.
7. Repeat steps 6 and 7 until the gate cycles without a fault and has the desired sensitivity.

Page 17
K. POWER FAIL OPERATION OPTION CONNECTION
a) Power Fail Operation Option Connection
CAUTION
Perform the next step (battery hookup) with care. Interchanging battery wires temporarily opens the
resettable fuse on gate operator board, disabling the power fail option.
To ensure a safe installation, the gate operator is shipped with the battery partially disconnected from the
Power Fail Option electronics. To enable this option:
• Connect white/red wire of option harness to positive (+) battery terminal.
b) Power Fail Operation Option Test
NOTES:
•The following procedures require turning main power to the gate operator off and on at its
dedicated circuit breaker. DO NOT shut off the Gate Operator Power switch unlessspecifically directed by the procedure, since this will shut off everything, including the Power
Fail Operation option.
•Because the battery may not be fully charged at the time of the test, we strongly suggest
moving the gate only one foot when performing the power fail test.
1. Set Power Fail switch S2 to the same position as switch S1 (Figure 4).
2. T urn on gate operator power switch.
3. Using the manual controls (Figure 5), initiate gate opening, then stop the gate about one foot
short of its fully open position.
4. T urn off main power to the gate operator. After about one minute the gate should start opening
and stop at its fully open limit.
5. T urn on main power to the gate operator.
6. Set Power Fail switch S2 to the opposite position.
7. Using the manual controls, initiat e gate closing, then stop the gate about one foot short of its
fully closed position.
8. T urn off main power to the gate operator. After about one minute the gate should start closing
and stop at its fully closed limit.
9. T urn on main power to the gate operator.
10. Set Power Fail switch S2 to the direction you desire the gate to move after a power outage.

L. CONNECTING INPUT WIRING
Figure 9. Control Board Wiring.
IMPORTANT: Before proceeding, see NOTES on the next page.
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 Installation and Operation of Master/Slave
Systems for X1 Series Gate Operators, Document Number 6001376).
Rev CDoc 6001288 (01-20285)14 of 39
Page 19
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.
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.
♦ If only one loop detector is used, the Outside loop must also be connected to the Inside loop
detector.
♦ To enhance system safety in Bi-Parting and Bi-Parting Latch Master/Slave systems, the Interrupt
loops, Shadow loops and Interrupt Bar switches may be connected to both gates. If this is done,
when connecting the two control boards, do not interchange input and common terminals. If
terminals are interchanged, inputs will not be detected and controller boards may be damaged.
See Installation and Operation of Master/Slave Systems for X1 Seriex Gate Operators, Document
Number 6001376.
4. If AC power to the controller board is cut off, the battery will retain the correct time and date.
M. BASIC GATE OPERATOR PROGRAMMING
Even if you plan to program the gate operator by telephone, you may want to enter some immediate
instructions during installation. The following list of instructions will help you set basic controls so the gate will
operate properly until you have time for full programming, either directly or by telephone. For complete
programming instructions, refer to the enclosed manual "SL 1000, SW 2000, BG 3000 and BG 3100-X1
Programming (-73 Bd),” Doc. No. 6001312.
To access programming mode: enter !!! 000000 (3 asterisks, 6 zeroes)

15Return to Factory Set Defaults6N/A101010 (partial), 191919 (full)
! IMPORTANT NOTE: BARRIER GATE BACKUP DISTANCES
Slide gates move at about one foot per second, so backup distances (Obstruction Sense, Overload
Sense, and Safety Bar Backup) are easy to enter. To move the gate one foot, you enter 12 inches.
Barrier gates, however, move in degrees per second, so it is the length of the gate that determines how
far the edge of the gate moves each second. As a result, entering backup distances for barrier gates is
different than for slide gates. Use the following table to enter barrier gate backup distances:

MODEL BG 3000-X1 OPTIONS
A. LIFTMASTER LOOP DETECTOR BOARDS
The model BG 3000-X1 has connectors for four LiftMaster-supplied loop detector add-on boards. These
boards interface with Interrupt and Exit loop sensors, which simply plug into the control board. The addon boards can be ordered pre-installed, or can be installed in existing model BG 3000-X1 units.
B. POWER FAIL OPERATION OPTION
The LiftMaster Power Fail operation Option may be ordered pre-installed on new units, or can be
purchased separately for installation in LiftMaster gate operator systems in the field. The Power Fail kit
includes a DC motor, belt, battery, battery support bracket assembly (includes bracket, 3 control relays,
rectifier and wire harness) and mounting hardware. Features of the Power Fail Option are as follows:
• The Power Fail Operation system fully opens (Fail Safe) or closes (Fail Secure) the gate (User’s
choice) one minute after a power outage. The gate will remain open or closed until AC power is
restored.
• When AC power is restored, the battery is charged up to its full potential, then continuously trickle
charged. Recharging takes from one to five hours, depending on the weight of the gate and how far
it moved during the outage. The age of the batter also increases the battery charging time.
NOTE: Battery capacity decreases over time, and should be replaced every two to three years.
• The charging section and controls for the Power Fail Operation are located on the control board.
• The motor sensing potentiometers (Right reverse, Left reverse and Inrush) on the Gate Operator board
may require readjustment if the Power Fail Operation option is installed in the field.
• Gate speed may be slightly reduced with the Power Fail Operation option installed.
IMPORTANT NOTE
During a power outage, all Gate Operator safety features are
disabled and only the limit switches stop movement of the gate.
C. GATE OPERATOR ARM
•The standard arm is 12 feet long and weighs 10 pounds. It is tapered to reduce weight and to
prevent warping, and has black and white striping to enhance visibility.
•An optional articulated arm is available for installations with limited overhead space.

D. MAINTENANCE
WARNING
To avoid injury, always turn off the unit power switch before working on gate.
Regular 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 gate usage.
• If the gate is installed in a private residence or small apartment house where usage is not
rigorous, 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: must swing freely without any impediment. Tighten set screws if loose !. Check hub,
grease if necessary.
2. Limit switches: contacts must bounce back rapidly when they are pressed and released.
3. Belt: Check for wear and tension (23 to 25 lbs.). Adjust the AC motor left or right to set the
proper tension.
4. Pulleys: must all line up and be firmly secured to their shafts. Tighten set screws if loose !.
5. G ear Box: Check for no oil leakage around the bushings. Do not oil gearbox.
6. Cont rol Board : Check for water damage or burned spots. All connectors secured to the
board.
7. Wiring: Check all wiring for any insulation damage. Check for loose wire connections.
8. No Rust : Check for rust throughout the unit. Check corners for water entrapment.
9. Fire Open: Activate Fire department switch to verify emergency gate opening.
10. Gate Sense: Check for the gate sensitivity (refer to Part 2, System Installation, paragraph J,
Gate Sensitivity Adjustments)
11. Power Fail Option: Check for proper operation (refer to Part 2, System Installation, paragraph
K, Power Fail Option Connection, item b, Power Fail Option Operation Test).
NOTE: !: To prevent loosening, LOCTITE threadlocker 242 is applied.

E. LIMIT CAM S
Gate operator limit cams are factory adjusted for 90° arm swing, and never need to be adjust in the field.
However, if long-term use requires replacing the limit cams, use the following procedure to install and adjust
the replacement limit cams
• Remove old limit cams by loosening the locking screws and removing cams from the shaft.
• When installing replacement limit cams, ensure that the limit cams are centered over their
corresponding limit switches.
• 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:
1. REPLACING AND ADJUSTING LIMIT CAMS IN A TYPICAL INSTALLATION
Figure 10. Setting Limit Cams for a Typical Installation.
1. Make sure that switch S1 is set to the “Left” position.
2. T urn on gate operator power switch.
3. Using manual CLOSE and STOP, move the gate to its proper closed limit position.
4. If not already loose, loosen the locking screw on the left limit cam and turn the cam counterclockwise until it just barely closes the limit switch.
5. Tighten the left limit cam locking screw.
6. Using manual OPEN and STOP, move the gate to its proper opened limit position.
7. If not already loose, loosen the locking screw on the right limit cam and turn the cam clockwise
until it just barely close the limit switch.
8. Tighten the right limit cam locking screw.
9. O pen and close the gate to check the limit cam settings. If required, readjust the limit cams
until they are set properly.

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 superseded by any command.
Continuous activations are superseded only by an overriding command.
" Activating any command when gate is at the open limit stops the Reclose Timer. When
any command (except Manual Close and Stop) clears, the Reclose Timer is reset.
MANUAL INPUTS: OPEN, CLOSE, AND STOP (TB2)
MAN OPENAct ivation f ully opens the gate. Continuous activation holds gate open.
Man Open overrides Anti-Tailgate (ATG, Reclose Timer, and all controls but
Man Stop.
Rev CDoc 6001288 (01-20285)30 of 39
Page 35
MAN CLOSEActivation fully closes the gate. Continuous activation holds gate closed.
Man Close overrides all controls but Man Stop, Man Open and Fire.
MAN STOPDe-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)
CYCLEReclose Timer Disabled:
Activation opens the gate, which remains open until another command isreceived. A Cycle command when the gate is fully open closes the gate.
This Alternate action allows a single command to both open and close 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 Inside 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 Inside Interrupt Loop clears.
FIREActivation opens the gate. Continuous activation holds the gate open. If
Reclose Timer is disabled, when Fire is deactivated, gate closes immediately.
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 LOOPSame 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 (swing gate only).
INSIDE/OUTSIDE INTERRUPT LOOP DETECTOR (TB16)

GLOSSARY
AC: Alternating Current. An electric current or voltage that reverses direction at regular intervals
Alternate Action: Ability to open and close a fully open gate by using the same open command.
Arc: The area that is swept by a swing gate from fully closed to fully open position.
ATG:Anti-tailgating refers to a method of immediately closing an opening gate behind a vehicle so that an
unauthorized vehicle cannot follow the authorized vehicle through the gate.
DC: Direct Current. An electric current of constant value flowing in one direction only.
Dynamic braking:Stopping the gate by activating the forward and reverse windings of the gate operator
motor in each half AC cycle.
Fault: An abnormal condition which causes the gate to stop to protect the gate and the user.
Gate sensitivity: The response of the gate operator to an exerting force to the gate.
Gear Box: A device that changes the speed and power of its driving force (motor).
Inrush current: Initial current drawn into an electrical device due to its capacitive or inductive nature.
Interrupt Bar or Edge:A switch which is installed at the edge of a gate to protect an object which is
situated between the gate and the gate frame.
LED:Light Emitting Diode. LEDs are indicators placed on the controller board which light up to indicate an
action in the system.
Limit switch:The closure of this switch indicates the gate has reached its open or close limit, causing the
gate to stop. There are two limit switches, open and close.
Limit cam:The excursion of this object corresponds to the gate traveling distance and closes the limit
switch at the open or close limit of the gate.
Loop sensor: A wire embedded in the ground for magnetically sensing large metallic objects (cars).
# Exit or Open Loop: activation opens the gate.
# Int errupt or Reverse or Reopen Loop: activation reverses or stops the gate.
# Shadow Loop:activation prevents a fully open or closed gate from moving while a vehicle is inside the
arc of a swing gate.
Loop detector: An electronic device that is activated by a loop sensor sensing a metallic object.
Master/Slave: A synchronized system containing a pair of gate operators.
Maglock: An electric magnet which is used to secure the closed gate.
Power Fail Option: A battery backup system which opens or closes the gate at power outage.
Pulley: A grooved wheel which transfers power via a belt.
Reclose Timer: An electronic timer which closes the fully open gate automatically.
Retry:A condition at which the stopped gate resumes its course automatically after the occurrence of a
Fault.
RPM: Rotation Per Minute is a term to indicate the speed of a rotary object
Sprocket: A toothed wheel which transfers power via a chain.
Thermal overload:A condition at which a heat producing device shuts off automatically when it reaches a
critical and damaging temperature level.
Torque: A force the causes rotation.
Torque Limiter:A clutch-like mechanism used to relieve excessive torque generated by the gate on the
gate operator.
