UL325 MODEL CLASSIFICATIONS (CON’T)
SAFETY ACCESSORY SELECTION-
All UL325 compliant LiftMaster gate operators will accept external entrapment protection
devices to protect people from motorized gate systems. UL325 requires that the type of entrapment
protection correctly matches each gate application.
Below are the 6 types of entrapment protection recognized by UL325.
Entrapment Protection Types-
Type A: Inherent obstruction sensing system, self-
contained within the operator. This system
must sense and initiate the reverse of the
gate within two seconds of contact with
a solid object.
Type B1: Connections provided for a non-contact
device, such as a photo eye can be used
as a secondary protection.
Type B2: Connections provided for a contact sensor.
A contact device such as a gate edge can
be used for secondary protection.
Type C: Inherent adjustable clutch or pressure relief
valve.
Type D: Connections provided for a control
requiring continuous pressure to operate
the operator open and close.
Type E: Built-in audio alarm. Examples include
sirens, horns or buzzers.
Additionally UL requires that all installations
must have warning signs in place to warn pedestrians of the dangers of motorized gate systems. Many
signs and labels are included with each operator.
These should be placed in plain view on both sides
of the gate.
UL325 Entrapment Protection Requirements-
The following chart illustrates the entrapment
protection requirements for each of the 4 UL325 classes
(For more information on UL325 classes refer to previous page.

In order to complete a proper installation you
must satisfy the entrapment protection chart shown
above. That means that the installation must have one
primary means of entrapment protection and one independent secondary means of entrapment protection.
Both primary and secondary entrapment protection
methods must be designed, arranged or configured to
protect against entrapments in both the open and close
directions of gate travel.
For Example:
For a gate system that is installed on a singlefamily residence (UL325 Class I) you must provide the
following: As your primary type of entrapment protection
you must provide Type A inherent (built into the opera-
tor) entrapment sensing and at least one of the following
as your secondary entrapment protection: Type B1-
Non-contest sensors such as photo-eyes, Type B2-

SAFETY INSTALLATION INFORMATION
1. Vehicular gate systems provide convenience and security. Gate systems are comprised of many component parts.
The gate operator is only one component. Each gate system is specifically designed for an individual application.
2. Gate operating system designers, installers and users must take into account the possible hazards associated with
each individual application. Improperly designed, installed or maintained systems can create risks for the user as well
as the bystander. Gate systems design and installation must reduce public exposure to potential hazards.
3. A gate operator can create high levels of force in its function as a component part of a gate system. Therefore, safety features must be incorporated into every design. Specific safety features include:
Gate Edges Guards for exposed rollers Photo-Electric Sensors
Screen Mesh Enclosed Track Vertical Posts
Instructional and Precautionary Signage
4. Install the gate operator only when:
a) The operator is appropriate for the construction and the usage class of the gate.
b) All openings of a horizontal slide gate are guarded or screened from the bottom of the gate to a minimum
of 4 feet (1.2 m) above the ground to prevent a 2 1/4inch (57.15 mm) diameter sphere from passing through
the openings anywhere in the gate, and in that portion of the adjacent fence that the gate covers in the open
position.
c) All exposed pinch points are eliminated or guarded, and guarding is supplied for exposed rollers.
5. The operator is intended for installation only on gates used for vehicles. Pedestrians must be supplied with a separate access opening.
6. The gate must be installed in a location so that enough clearance is supplied between the gate and adjacent structures when opening and closing to reduce the risk of entrapment.
7. The gate must be properly installed and work freely in both directions prior to the installation of the gate operator.
8. Controls must be far enough from the gate so that the user is prevented from coming in contact with the gate while
operating the controls.
9. Controls intended to be used to reset an operator after 2 sequential activations of the entrapment protection device
or devices must be located in the line of sight of the gate, or easily accessible controls shall have a security feature to
prevent unauthorized use.
10. All warning signs and placards must be installed where visible in the area of the gate.
11. For a gate operator utilizing a non-contact sensor:
a) See instructions on the placement of non-contact sensor for each type of application.
b) Care shall be exercised to reduce the risk of nuisance tripping, such as when a vehicle trips the sensor while
the gate is still moving.
c) One or more non-contact sensors shall be located where the risk of entrapment or obstruction exists, such
as the perimeter reachable by a moving gate or barrier.
12. For a gate operator utilizing a contact sensor such as an edge sensor:
a) One or more contact sensors shall be located at the leading edge, trailing edge and post mounted both
inside and outside of a vehicular horizontal slide gate.
b) One or more contact sensors shall be located at the bottom edge of a vehicular vertical lift gate.
c) One or more contact sensors shall be located at the pinch point of a vehicular vertical pivot gate.
d) A hard wired contact sensor shall be located and its wiring arranged so the communication between the
sensor and the gate operator is not subject to mechanical damage.
e) A wireless contact sensor such as the one that transmits radio frequency (RF) signals to the gate operator
for entrapment protection functions shall be located where the transmission of the signals are not obstructed or
impeded by building structures, natural landscaping or similar obstruction. A wireless contact sensor shall
function under the intended end-use conditions.
6
SAFETY LABEL PLACEMENT
The UL required Warning Signs must be installed in plain view and on both sides of each gate installed.
Each sign is made with fastening holes in each corner and should be permanently secured in a suitable
manner. Warning label on unit should be visible.
SAFETY PRECAUTIONS FOR SWING & ORNAMENTAL “GRILL TYPE” GATES
Injuries can occur when pedestrians stand in the path of a moving gate, or in their entrapment zones.
Non contact sensors, such a photo eyes, must be incorporated into the swing gate system to assist in
the protection of people who may come near the gate operating system. Gate edges maybe used as
additional entrapment protective devices.
UL325 requires that, when used, contact sensors shall be located so that they protect against entrapment during both open and close gate cycles.
01-G0665F18
Injuries occur when people are caught between a moving gate or a rigid object such as a stationary
fence post or fence (See Safety Brochure for details).

POST MOUNTING (SW470)
NOTE: For the following instructions refer to figures 1 & 2.
1. Locate and anchor two posts made of 3” outer
diameter heavy walled pipe. Posts should be parallel
and square to the gate. (See figure 1)
IMPORTANT NOTE: The distance between mounting
posts and the relative location of the operator to the
gate and fence is critical.
2. Locate electrical conduit, as required, prior to pouring concrete.
3. Set mounting post and electrical conduit in place.
Knockouts for 3” pipe clamps (not supplied) are provided in the operator.

SAMS (SEQUENCED ACCESS MANAGEMENT SYSTEM)
SAMS DEFINITION
The Sequenced Access Management System or SAMS allows the customer more control when managing vehicular entrances
to areas such as apartment complexes, businesses and gated communities. The basic concept of the system is that traffic is
controlled by two gates installed in tandem, a fast moving gate such as a barrier gate operator and a slower moving more
secure or ornamental gate such as a single or pair of slide/swing gate operator. The design of this gate system balances the
demands of speed during high traffic periods with security during low traffic periods. Barrier gates typically have the fastest open
times of the many gate operator types and the slide or swing gates allow you to effectively seal off the perimeter of the complex you are planning to secure.
NOTE: Connect all entry devices to the slide or swing gate. If using a device, such as a 7-day timer, to latch the lide or swing
gate open during high traffic times, connect the device’s N/O relay output to the GL board’s Interrupt Loop input. Once the
device activates the Interrupt Loop input, the next vehicle to access the SAMS system will lock the gate in the open position
until the device deactivates. When the device deactivates, the timer to close will automatically close and secure the gate.
SAMS OPERATION
1) When an authorized vehicle accesses the gate system, the
SAM system responds by first opening the gate farthest from the
vehicle, the swing or slide gate.
2) Once the swing or slide gate is open, the barrier gate begins
its open cycle.
3) Once the barrier is open the vehicle may pass through the
SAM system. At this point you have two options in how you
would like to initiate the SAM systems closure. You may chose
to:
a) Use a timer to close system to automatically
close the barrier gate after a preset amount of
time or
b) Use a loop system to close the barrier gate after the
vehicle has passed through the SAM system.
4) Once the barrier gate is closed the slide or swing gate will
activate its internal timer to close and begin closing.
5) If another authorized vehicle accesses the SAM system
before the slide or swing begins to close the barrier will open and
allow the vehicle to pass through the SAM system.
SAMS WIRING
1) Install conduit between the BG770 and the SL540/570 for
SAMS control wiring.
2) Run a 4-conductor cable in the conduit between the BG770
SL540/570.
3) Locate the SAMS relay terminals (J5) on the GL board in the
SL540/570 and locate the auxiliary limit switch in the BG770.
4) Attach a wire from the SAMS relay terminal (J5) on the GL
board to terminal 1 on the BG770 terminal strip.
5) Attach a wire from the SAMS relay terminal (J5) on the GL
board to terminal 3 on the BG770 barrier gates terminal strip.
6) Attach a wire from terminal J1-5 on the GL board to the common (COM) on the auxiliary limit switch in the barrier gate.
7) Attach a wire from terminal J1-8 on the GL board to the normally open (NO) on the auxiliary limit switch.
8) Test for correct functionality of the SAM system.
6) If another authorized vehicle accesses the SAM system during the slide or swing gates closing cycle the SAM system will
reopen the slide or swing gate. Once the slide or swing gate
reaches the open position the barrier will then open to allow the
vehicle to pass through the SAM system.
7) If no other authorized vehicles access the SAM system the
swing or slide gate will close followed by the barrier.

CONTROLLER PROGRAMMING AND FEATURES
MOTOR LEARN FUNCTION (FORCE PROFILE)
This function is preprogrammed at factory. If either board or motor is replaced, the
controller will need to be programmed to “LEARN” the specific motor RPM profile
only of your operator. Switch “S3” is provided for this. This is important for accurate force control. Failure to do so may result in improper and unsafe operation.
To learn the motor:
NOTE: Motor Learn must be performed in stand along mode.
1. Detach the unit from the gate, the motor needs to be learned without a load.
2. Press the motor learn button. The yellow LED should start to flash rapidly.
3. Install a jumper on either the hard open or the hard close input terminals. The
motor will run for a few seconds and then stop. If the LED goes out the motor is
learned. If the unit activates a limit before completing the learn or some other error
occurs the LED will go back to on continuously. If this happens try learning while
running in the opposite direction.
NOTE: It is important that the jumper is in constant contact while the gate is
moving in learn mode.

4. Reconnect the unit to the gate, reset the limits and adjust the force control.
FORCE CONTROL
Set the force control pot such that the unit will complete a full cycle of gate travel
but can be reversed off an obstruction without applying an unreasonable amount of
force. On most operators this will be around the middle of the range.
NOTE: For LED location refer to illustration on previous page.
DIAGNOSTICS (LEDS AND CODES)
There are three diagnostic LEDs. Two red LEDs
(OL, CL) are indicators for the open and close limits.
The LEDs are illuminated when the limit switch contacts are closed.
The third amber LED (DIA) is used to blink out diagnostic codes. The number is the count of the number of times the LED is on in an 8 second period.
The LED is on for approximately 1/2 second and
repeats every second until the number is reached.
There will be a pause following each pulse cycle (16 pulses) to differentiate between the different diagnostic codes.

Open Photo Eye (Pause): When the controller is configured for photo eyes, the input functions to pause the gate
during the opening cycle. Once the input is cleared the
gate continues to open.
Open Edge: When the controller is configured for safety
edges, the input functions to reverse the gate to the close
limit when the edge is activated during the opening cycle.
PROGRAM SETTINGS (DIP SWITCH #4)
EDGE/PHOTO CLOSE
This switch (S2-4) selects edge or photo sensor for the gate
closing protection input.
Close Photo Eye (Reverse): When the controller is configured for photo eyes, the input functions to reverse the gate to
the open limit when activated during the close cycle.
Note: Timer to close will reset if enabled.
Close Edge: When the controller is configured for safety
edges, the input functions to reverse the gate to the open limit
when activated during the close cycle. The entrapment is not
cleared at the limit and the timer to close will be disabled. The
timer to close may be enabled by activating the interrupt loop,
soft open or hard open input.
DUAL GATE COMMUNICATIONS
The controller is capable of running the operator in a master or second mode depending on (S4) switch setting.
Before initiating any command the master unit queries for the presence of a “second unit” for a time period of one second. If the master
gets no response the operator will operate in a stand alone mode.
NOTE: For single unit applications, a jumper must be placed
between J4-1 and J4-2.
In this mode no further communications will
take place during travel. If the master detects the presence of a second unit the master will continue to query the second unit during travel. The second unit will send a response to the master for every
query. The second operator will stop if there is a period of one second or more of no communications.
When two operators are connected in dual gate configuration accessories may be connected to either the master or second.
NOTE: Do not run Master/Second communication wiring in
the same conduit as the power and control wiring.
NOTE: The Second unit will require a normally close stop
circuit for proper system operation.
FIGURE 1
NOTE: After Master/Second wiring has been completed
and the S4 switch programmed, both units must have their
power cycled to initiate proper Master/Second communication.
NOTE: The motor learn function must be completed in
stand alone mode prior to Master/Second wiring.
23
TROUBLE SHOOTING
If the yellow LED blinks six times there is a master/second unit
communication failure. If operator is a single unit make sure there is a
jumper across terminals J4-1 and J4-2. If operator is in a dual gate
configuration make sure that the communication wiring between the two
units is undamaged and complete.
g
p
y
Master/Second Operation: Make sure that the master/second wiring is
installed correctly and is intact (not dammaged).

Review program settings pages 22-23 and check both the master and
second for proper programming.
Operator runs in
the wrong
direction.
The operator's main power is
out of phase (three phase only).
Turn off the unit's main power at the breaker and swap any two power leads
at the operator's main power switch. Apply power and retest the operator.
See important note on page 15.

This pot must be set so that the gate will run smoothly normally and reverse
when encountering and obstruction. See page 21.
Disconnect the gate from the operator and swing the gate open and close by
hand at normal operating speed. Make sure that the gate swings smoothly
and does not bind. If the gate is hard to move or binds repair the gate.
Both LEDs will indicate the activation of entrapment protection devices on
terminals J1-9 & J1-10 on the GL board. Remove the devices and retest. If
the operator now runs without fault, check those accessories as well as their
wiring.
Make sure that the sensor is adjusted so that it is within 10-15 thousandths
of and inch (business card thickness) from the magnets located on the
gearbox pulley.

HALL EFFECT SENSOR ADJUSTMENT
WARNING
NOTE: Normally the Hall Effect sensor does not
need adjustment, but may go out of alignment due to
shipping vibration or rough handling.
These operators use an internal entrapment protector system. This system consists of the GL control
board, magnet, and Hall Effect sensor. It may
become necessary to adjust the sensor for correct
alignment. To do so please perform the following
steps:
WARNING
TO AVOID SERIOUS PERSONAL INJURY OR
DEATH DISCONNECT ELECTRIC POWER
BEFORE ADJUSTING HALL EFFECT.
3. Tighten screws to secure assembly.
1. Loosen the two screws holding the hall bracket to
the frame.
2. Adjust the hall effect bracket so that the hall effect
board is:
a. Parallel with the pulley.
b. .020" away from the pulley's magnet. Use
a feeler gauge to measure the distance.

All power must be disconnected from operator before maintenance can be performed.
All maintenance must be done by a LiftMaster dealer.
Notes:
1. Severe or high cycle usage will require more frequent maintenance checks.
2. Inspection and service should always be performed anytime a malfunction is observed or suspected.
3. 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 as needed.
4. It is suggested that while at the site voltage readings be taken at the operator. Using a Digital Voltmeter,
verify that the incoming voltage to the operator it is within ten percent of the operators rating.
