Safety Instructions
WARNING
To reduce the risk of injury or death, it is important to read all safety instructions.
These safety instructions have been prepared by LiftMaster, the manufacturer of the barrier gate. As
the manufacturer of only part of the total barrier gate system, we do not know what type of controls or
safety equipment that has been selected as part of your system.
An automatic vehicular gate arm is a large, heavy object that moves with the help of an electric motor.
A moving gate arm can cause serious injury or death. Your safety and the safety of others
depends on you reading, understanding, and following through on the safety instructions in this
manual. It is important that both the installer and end users are aware of the hazards of your specific
system.
If you have any questions or doubts about the safety of your system, or if you do not completely
understand everything in this manual, contact LiftMaster.
Before Installation
ꢀ Installation of this barrier gate must be done by a qualified installer.
ꢀ Check to make sure that the available power supply to be connected to the operator is of the
same voltage, phase, frequency, and wattage as indicated on the nameplate of the operator.
ꢀ Installation and wiring must be in compliance with local building and electrical codes.
ꢀ It is strongly recommended that you use safety equipment with this barrier gate
operator. There are many types of safety devices available; sensing edges, photo-electric
controls, motion detectors, and vehicle detectors are some of the more common types.
Audible and/or visible warning devices are recommended when automatic controls are used in
the gate operating system.
If you need advice regarding the type of safety equipment that should be used on your
application or wish to purchase such equipment, contact the supplier of the barrier gate, or
contact LiftMaster. Without safety equipment, the gate could cause serious injury or
death.
ꢀ Carefully plan the location of barrier gate control equipment. Do not locate controls in places
where children will be able to reach or play with them. Be sure the person operating the
controls can see the full area of movement of the gate arm from the point of operation.
During Installation
ꢀ Do not place hands or fingers in or near the barrier gate unless power is off. Moving chains,
pulleys, or belts can catch clothing or fingers and cause severe injury.
ꢀ Always disconnect power and lock out whenever installing or servicing the barrier gate.
ꢀ If the barrier gate utilizes any automatic means of operation (such as automatic timed
closings), post warning signs that are clearly visible to persons in the area warning of the
particular hazards of the system.

After Installation
ꢀ Be sure that the operator, controls, and safety devices have been tested and are functioning
properly.
ꢀ Review the operation of the gate and safety equipment with the owner or end user. Be sure
that the end user is aware of all safety instructions and hazards of the operating system.
ꢀ Inform the owner or end user that the barrier gate and all control and safety equipment should
be maintained regularly. The entire gate system should be checked at least once monthly to
ensure that it is functioning properly.
With a safety edge installed, the gate must reverse on contact with a rigid object. If non-
contact sensors are connected to the Hold Open input and an object activates them, the
operator will stop a closing gate. 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 injury
or death.
ꢀ Leave all installation manuals, instructions, and safety information, including this manual, with
the owner or end user.
ꢀ The entrance is for vehicles only. Pedestrians must use separate entrance.
ꢀ Keep gates properly maintained. Read the owner's manual. Have a qualified service
person make repairs to gate hardware.

Vehicle Detectors
Almost all types of vehicle detectors may be used in conjunction with both model BG770 and BG790.
More than one detector may be connected to the gate, and may be mounted inside of the cabinet.
Connect the detector(s) according to the instructions on the wiring diagrams supplied with the gate and
with the detector itself.
FACTORY SUPPLIED PLUG-IN DETECTORS
LiftMaster P/N 71-416-7NH = 24V
Please note: Previous models used 115V detectors (P/N 71-416-3NH).
OPEN LOOP DETECTOR
1
Snap the detector onto one set of the four board mount standoffs located on the inside of
the electrical cabinet. Plug the harness into the connector marked "OPEN".
2
Connect the two loop wires to terminals P1 and P2 as shown on the wiring diagram.
HOLD OPEN LOOP DETECTOR
1
Snap the detector onto one set of the four board mount standoffs located on the inside of
the electrical cabinet. Plug the harness into the connector marked "HOLD OPEN".
2
Connect the loop wires to terminals P3 and P4 as shown on the wiring diagram.
Radio Controls
All types of standard radio controls may be used in conjunction with model BG770 and BG790. If the
receiver is mounted inside of the gate enclosure, a commercial coaxial antenna should be used and
extended through the side of the cabinet.
POWER CONNECTION
All radio receivers require a power supply. If the receiver requires 24 volts AC you may power the
unit from the gate control circuit. To do this, connect the radio receiver power wires to Terminals
#3 and #6 on the control terminal strip. If the receiver requires 115 volts AC or other power, you
will need a separate power source.
A standard residential door radio receiver has a three wire connection marked 1, 2, 3. If you have
this type, you may connect to operator terminals R3, R1, and R6. The transmitter button will open
the gate if it is fully closed.
CONTROL
If you have a standard residential 3 wire receiver and made the power connection described on
page 19, you are finished with the radio connections. If you want to use a radio control (such as a
single button), you must order an optional kit (P/N 90-PGR).

Card Readers, Keypads, or other
Almost all types of access control devices may be connected to models BG770 and BG790. More
than one device may be connected in parallel. All devices connected according to the instructions
below will open the gate and reverse the gate if it is closing.
MOUNTING LOCATION
Mount or install the access control device within sight of the gate and according to the instructions
supplied with the device. Some devices require their own power supply. Do not use the 24 volt
power in the gate to supply other devices. Use either direct line voltage (115V or 230V) or
other external power source as required by the particular device.
NOTE: Most access control devices have an isolated, normally open output contact to
connect to the gate. If yours does not, or if you are unsure of or unfamiliar with these
terms, consult the supplier of the device or a qualified gate installer.
CONTROL CONNECTION
TURN OFF POWER and connect the two output terminals (or wires) of the access control device
to the terminals #1 and #3 on the control wiring terminal strip. Use a wiring method that will
provide permanent, durable, and weatherproof connection between the gate and the access
device.

ACCESS CONTROL “EMERGENCY” BYPASS
To open the gate in an emergency, remove the keyed access cover and open the electrical
cabinet. Flip the AUTO/MANUAL switch to the "MANUAL" position.
The gate arm will remain in the up position, and no other control device will have any effect until
the switch is set back to the "AUTO" position.

Troubleshooting
When troubleshooting, one of the first things to do is try to isolate the problem area. The four (4) main
areas to check out are:
Power
Accessories
Operator’s Primary Voltage
Operator’s Low Voltage
1. Power
Always use extreme caution! Some possible symptoms of power problems include:
The obvious one is – the operator will not run.
The operator runs slow.
Circuit breakers or fuses keep tripping.
Motor overload keeps tripping.
Operator starts but then stops.
1A.
Using a V.O.M., take a voltage reading at the control transformer’s primary terminals. You should
get a reading as follows:
Nominal Volt.
Min.
Max.
120v.
230v.
460v.
108
207
414
132
253
506
Table 4
If you get a reading that does not fall into the minimum/maximum area, then check out your main
power supply. Also, make sure that the operator was ordered with the proper voltage and phase.
Another item to check is the wire run from the power supply to the operator. Double check the
gauge of the wire versus the distance.
1B.
If the voltage reading is O.K. from 1A, then take the same voltage reading with the operator
running. If voltage drops below the minimum with this reading, then there could be an excessive
current draw somewhere, or a wire AWG is too small.
1C.
In some cases, power drops can occur at only specific times during the day or night. This can be
caused by increased power demands in a general area at a specific time—particularly areas
undergoing rapid growth.

2. Accessories
Add-on accessories can create many of the problems that are credited to the operator. Many
applications have more than one accessory item attached to the operator and some of these items
even draw their power from the operator.
Some of the symptoms that can show up because of accessories:
The operator won’t close.
The operator won’t open.
The operator will not run.
The operator begins to run, then stops or reverses.
2A.
Whenever the problem is thought to be an accessory and there are more than one connected to
the operator, always disconnect one accessory at a time and then test the system. This will
hopefully isolate which item is causing the problem.
2B.
If an accessory item is being used as an access control device (used to open or close), falls in the
closed position or sends out a continuous signal. The operator will hold the gate in one position
until the signal from the accessory is removed.
2C.
In some applications, the gate may begin to move then either stop or stop and reverse within a
couple of seconds. This can be caused by an external obstruction device that has failed.
2D.
If there are many accessories attached to and powered by the operator, there may be too much
current draw for the operator’s control transformer. This operator can only supply approximately 2
amps @ 24 vac. Double check all accessories for their current requirements.
3. Primary Voltage Circuit
Use extreme caution when troubleshooting the primary voltage circuit! There are five (5) items
in this circuit that could be causing trouble, and they are:
Motor
Contactor (see Figure 15)
Power Disconnect Switch
Transformer
3A.
The first thing to check is the incoming power. Is it there
at the incoming side of the power disconnect switch?
3B.
If there is power, then check for it at the transformer
primary terminals. If there is voltage at the switch and
none at the transformer, then you probably have a bad
power disconnect and it should be replaced. Check
secondary output of transformer for 24VAC output.

3C.
If 3a and 3b check out O.K., then manually disconnect the operator from the gate. Very carefully,
using a screwdriver with an insulated handle, press down on the open side of the contactor. Then
do the same to the close side of the contactor. Did the operator run in both directions? If it did,
the problem may be in the low voltage control circuit. It if did not, then the problem is either in the
contactor or the motor.
3D.
If the contactor is suspected to be causing the problem, first carefully check all wiring connections
at the contacts (see Figure 15). Disconnect Power! Using a V.O.M., take continuity readings
across the contacts of the contactor. Remove wires from one side of the contactor. Place one
probe on 1 and the other on 2. You should get NO continuity; now press down on the contactor;
you should get a continuity reading. Repeat this on all of the contactor’s contact points.
3E.
If the problem is thought to be the motor, it is recommended that it be replaced. It is possible that
the thermal overload inside the motor has overheated. Wait approximately 15 minutes, then try
running unit.
NOTE: Some motors have the overload built into the motor itself, while other units have a
separate overload in the controller (Model BG770 uses a manual reset overload).
4. Low Voltage Circuit
4A.
The first thing to check is the circuit breaker.
4B.
The secondary voltage must be between 22 and 30 vac. This voltage can be checked at the
circuit board at terminals 3 & 6.
4C.
The contactor coils receive 24vac. To activate the motor in either the open or close direction.
There are two contactor coils (one for open and one for close).
4D.
The limit switches are S.P.D.T. (single pole, double throw). These limit switches tell the operator
to shut off at either the full open or full close position.

General Reference Information
THE GATE
Double check the gate and its related hardware. Does the gate move freely? Are there
unprotected pinch points? - If yes, then correct.
WIRING DIAGRAM
Always reference the wiring diagram that was supplied with the operator. Note that some of the
accessory items may have their own wiring diagram.
If you cannot correct the problem or if you feel you will require technical assistance, contact your
local distributor or dealer. If you do not have a distributor or dealer, then contact us for technical
assistance. Please when calling for assistance, make sure you have the gate operator model
number, voltage, phase, horsepower and a list of all accessories that are attached to the operator.

CAUTION
When servicing, always disconnect operator from electrical power supply.
NOTES
Inspection and service should always be
performed anytime a malfunction is
observed or suspected.
Severe or high cycle usage will require
more frequent maintenance checks.
It is suggested that while you are at the
site, take some voltage readings of the
operator. Using a VOM, double check the
incoming voltage to the operator to make
sure it is within ten percent of the
operator’s rating.
Limit switches may have to be reset after
any major drive chain adjustments.
BG790: If lubricating chain, use only a
proper chain lub spray or a lightweight
motor oil. Never use grease or silicone
spray.
While you are at the site, now would be a
good time to let the owner or manager
know about any new items available or
any safety items that could and should be
added to the site.
When servicing, please do some “house
cleaning” of the operator and the area
around the operator. Pick up any debris in
the area. Clean the operator if needed.
LIMITED BEARING LUBRICATION
The barrier gates require very little in the way of maintenance. Motor and shaft bearing normally
should not require lubrication. The gear oil in the gear reducer is sealed in. Unless a severe
problem causes a seal to break, it should never need replacement. If gear oil is required, use
Mobilube C SAE140 or equivalent.
GREASE TURNBUCKLE
Periodically grease the ball ends of the turnbuckle, depending on the gate’s frequency of use.
