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 slide gate system that is installed on a
single-family 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 operator)
entrapment sensing and at least one of the following as your
secondary entrapment protection: Type B1- Non-contact
sensors such as photo-eyes, Type B2- Contact sensors such
as gate edges or Type D- Constant pressure control.
KEEP CLEAR! Gate may move at any
time without prior warning.

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
• Photoelectric Sensors
• Screen Mesh
• 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' (1.2 m) above
the ground to prevent a 2 1/4" (6 cm) 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. The pedestrian access opening shall be designed to promote pedestrian usage. Locate the gate such that persons will not
come in contact with the vehicular gate during the entire path of travel of the vehicular gate.
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. Swinging gates shall not open into public access areas.
7. The gate must be properly installed and work freely in both directions prior to the installation of the gate operator.
8 Controls intended for user activation must be located at least six feet (6') away from any moving part of the gate and where the
user is prevented from reaching over, under, around or through the gate to operate the controls. Outdoor or easily accessible
controls shall have a security feature to prevent unauthorized use.
9. The Stop and/or Reset (if provided separately) must be located in the line-of-sight of the gate. Activation of the reset control shall
not cause the operator to start.
10. A minimum of two (2) WARNING SIGNS shall be installed, one on each side of the gate where easily visible.
11. For a gate operator utilizing a non-contact sensor:
a. Reference owner’s manual regarding 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 where the risk of entrapment or obstruction exists, such as 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. 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.
d. 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.
e. One or more contact sensors shall be located on the inside and outside leading edge of a swing gate. Additionally, if the bottom
edge of a swing gate is greater than 6" (152 mm) above the ground at any point in its arc of travel, one or more contact sensors
shall be located on the bottom edge.
f. One or more contact sensors shall be located at the bottom edge of a vertical barrier (arm).

• Injuries occur when people get their hands or feet caught
between the top or bottom of the gate and the gate roller.
These potential pinch-points should be guarded against at all
times. Enclosed style gate tracks are available for refitting of
these rollers from many fence suppliers. Also, roller guards
are available for installing over the rollers.
• UL325 requires that, when used, contact sensors shall be
located at the leading edge, trailing edge, and be post
mounted both inside and outside of a vehicular horizontal
slide gate. Non-contact sensors such as photo eyes must
protect during both open and close gate cycles.
• Injuries occur when people put their hands and arms
through openings in the grill while the gate is operating.
They cannot retract their arm and it gets caught between the
moving gate grill and the stationary fence post or fence. This
potential hazard can be averted by placing a 4' screen mesh
on the gate to prevent access through openings anywhere
the gate may travel. See Safety Brochure for details.
To prevent entrapment injuries, mount controls at least 6'
from the gate or any moving parts of the gate.

SUSPENSION SYSTEM
Gate Stop
1. The suspension system is semi-factory set; simply loosen the
suspension separator bolt completely. This will allow both
wheels to pinch the drive rail.
NOTE: It is suggested that the separator bolt be removed and left
with unit. If it is not removed, make sure that it can not interfere
with suspension system.
2. If more or less pressure is required, adjust both upper and
lower suspension spring lock nuts as desired. Both springs
should apply about the same amount of pressure.
IMPORTANT:
If using the LiftMaster drive rail, make sure that the drive rail
guide wheel is positioned properly.
It is very important that the suspension system is adjusted
properly. This system puts pressure on the drive wheels so they
can pinch together on the drive rail. This system also allows the
drive wheels to “float” so they can follow any slight misalignment
of the drive rail. If the springs are over tightened, it will reduce
their life span. But, on the other hand, if they are under tightened,
the drive wheels may slip on the drive rail.

MANUAL OPERATION
NOTE: When manually opening or closing the gate, it is not, in
the beginning, easy to get the gate started. Since fluid has
accumulated in the drive motors, it may take more force to get
the gate started.
The pump is equipped with a manual bypass valve. By positioning
the valve handle down (manual operation), the gate can be
manually opened or closed.
NOTE: A back-up to this is the suspension separator bolt. By
tightening this bolt, the drive wheels will be pushed off by the
drive rail.

ADJUSTMENT
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 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:
1. The hall effect sensor must be centered over the magnet.
Adjust with horizontal screws.
2. The hall effect sensor must be level.
3. The hall effect sensor air gap should be adjusted to
.010 - .015 of an inch. (The thickness of a business card may
be used to gauge the correct distance). Adjust with vertical
screws.
To reduce the risk of SEVERE INJURY or DEATH:
• Disconnect power BEFORE performing ANY adjustments.
CAUTION

FORCE ADJUSTMENT
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 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.
NOTE: Motor Learn must be performed in stand alone mode.
1. Detach the unit from the gate, the motor needs to be learned
without a load. (Do not use the manual release, the limit shaft
must be turning during learn sequence.)
2. Press the motor learn button. The yellow LED should start to
flash rapidly.
3. Push and hold down either the open or the close buttons. 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.
4. Reconnect the unit to the gate, reset the limits and adjust the
force control.

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 TB11 and TB12. 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.

SEQUENCED ACCESS MANAGEMENT SYSTEM (SAMS)
SAMS DEFINITION
The Sequenced Access Management System or SAMS allows the customer more control when managing vehicular entrances to areas
such as industrial complexes, businesses and airports. 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 slide 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 SAM system will lock the gate in the open position until the device deactivates.
When the device deactivates, the timer to close will automatically close 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.
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.
SAMS WIRING
1. Install conduit between the BG770 and the HS670 for SAMS
control wiring.
2. Run a 4-conductor cable in the conduit between the BG770
HS670.
3. Locate the SAMS relay terminals (J5) on the GL board in the
HS670 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 TB5 to the common (COM) on the
auxiliary limit switch in the barrier gate.
7. Attach a wire from terminal TB8 to the normally open (NO) on
the auxiliary limit switch.
8. Test for correct functionality of the SAM system.

Terminals 6 & 5 (Com) - Open
These terminals are intended for use as a general open control.
Accessories that may be wired to this input include: Telephone
Entry Systems, Radio Receiver (Commercial Applications), Exit
Loop Detector, Keypads, 7-Day Timer. NOTE: Will not override a
double entrapment (signalled by the gate stopped and
entrapment alarm on).
Terminals 7 & 5 (Com) - Open Override Control Input
These terminals are intended for use only with the open control
of a three-button station that is installed within line of sight of the
gate. A momentary activation of this input will cause the gate to
open. Activation of this input for longer than three seconds will
enable the control to be used as a constant pressure override
device. This will allow the user, in emergencies, to override a
failed accessory such as a loop detector or photo-eye.
Terminals 4 & 5 (Com) - Close Override Control Input
These terminals are intended for use only with the close control
of a three-button station that is installed within line of sight of the
gate. A momentary activation of this input will cause the gate to
close. Activation of this input for longer than three seconds will
enable the control to be used as a constant pressure override
device. This will allow the user, in emergencies, to override a
failed accessory such as a loop detector or photo-eye.
Terminals 8 & 5 (Com) - Interrupt (Safety) Loop Input
These terminals are intended for use with a loop detector. This
input functions to reverse a closing gate to the open limit.
Latching this input will reset the timer to close.
Terminals 2 & 5 (Com) - Shadow Loop Input
These terminals are intended for use with a loop detector and is
primarily used on swing gate operators. This input protects cars
by preventing the gate from moving off of the open or close limit
when the shadow loop input is active.
The GL operator controller board senses commands using
+24VDC from terminal #3. Commands are seen when +24VDC are
applied to the controller’s input terminals. NOTE: The GL

take precautions when adding any additional surge protection.
Terminals 1 & 5 (Com) - Single Button Input
These terminals are intended for use with a radio receiver in a
residential application or as a single button control. This allows
the user to open the gate by activating the transmitter when the
gate is closed or between limits. This input also gives the user
the ability to close the gate by activating the transmitter when the
gate is on the open limit.
Terminals 3 & 5 (Com) - Stop/Reset Control Input
These terminals are intended for use with a single stop/reset
button or the stop control of a three-button station that is
installed within line of site of the gate. This input functions to
stop the gate or to reset the gate after an entrapment fault. Note:
This input uses a normally closed circuit and the operator will not
run until a stop control is installed. NOTE: It is strongly
recommended that a jumper be used for testing purpose only
and not for normal operation.

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 (1-6 pulses) to differentiate
between the different diagnostic codes.

2) Problem in the motor
3) Problem in the contactor
4) Rail slippage
FIX
➤ Check the green LED (D17) on GL board. If the green LED is off,
check to make sure a stop control has been installed across terminals
TB1-3 and TB1-5 of the Terminal Strip.
➤ 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 TB1-11 and TB1-12. If operator is in a dual
gate configuration, make sure that the communication wiring between
the two units is undamaged and complete.
➤ If the yellow light is solid, the board needs to learn the motor. Follow
the directions on page 14.
➤ If any red LEDs are on, check the corresponding input. An installed
accessory may be wired incorrectly or malfunctioning. Remove the
accessory and test the operator.
➤ If the open or interrupt loop LED is on, make sure factory plug-in loop
detectors are working properly and appropriate loops are installed on
the loop input terminals.
➤ Measure the incoming voltage at the unit’s on/off switch. It should be
within 5% of the operator’s rating when running. Make sure that the
proper wire gauge was used for the distance between breaker and
operator by consulting the wiring specifications section on page 12 of
this manual.
➤ Measure the voltage at terminals R1 and R2 in the operator. This
voltage should be within 5% of 24VAC. If the high voltage power is
good and the secondary voltage power is bad, check to make sure the
circuit fuse is not blown and that the correct primary tap is used on
the transformer. If fuse and tap are correct replace the transformer.
➤ Stand-alone Operators: Make sure there is a jumper installed across
TB11 and TB12.
➤ Master/Second Operation: Make sure that the master/second wiring is
installed correctly and is intact (not damaged).
➤ If both primary and secondary power is good, check to make sure
that the J2 connector is making good contact with the pins on the GL
board. If all is good, replace GL board.
➤ Remove all accessory devices and test the operator. If the contactor
stops chattering, find an alternate power source for some of the
devices.
➤ Measure the incoming line voltage at the unit’s on/off switch. It should
be within 5% of the operator’s rating when running. Make sure that
the proper wire gauge was used for the distance between breaker and
operator by consulting the wiring specifications section on page 12 of
this manual.
➤ Measure the incoming line voltage at the unit’s on/off switch as well
as the meter base or sub panel. Make sure there is not a major
change in voltage. The voltage at the operator should be within 5% of
the operator’s rating when running.
➤ Check the number of amps currently being drawn from the panel.
Make sure that the total power being drawn does not exceed the
panel’s rating.
➤ Make sure that the proper wire gauge was used for the distance
between breaker and operator by consulting the wiring specifications
section on page 12 of this manual.
➤ Perform a visual inspection of the motor. Examine the motor’s labels
for any distortion or signs of overheating. Replace the motor if it is
humming, grinding or making excessive noise. Note: Repeated motor
problems indicate poor primary power.
➤ Examine the contactor for sparking, smoke or burn marks. Remove
the wires from one side of the contactor, then measure the contact
points for high resistance (above 1 ohm). Replace the contactor.
➤Observe the drive wheels as they move the gate. If the wheels slip on
the rail, tighten the compression springs until the rail no longer slips.

does not bind. If the gate is hard to move or binds, repair the gate.
➤ Observe the drive wheels as they move the gate. If the wheels slip on
the rail, tighten the compression springs until the rail no longer slips.
➤ Make sure that the brake operates correctly. The brake should
disengage when the contactor activates and engage when the
contactor releases.
➤ Both LEDs will indicate the activation of entrapment protection
devices on terminals TB1-9 and TB1-10 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 centered over the
limit shaft’s magnet and is 10-15 thousandths of and inch (business
card thickness) from the magnet.
➤ Replace the sensor if it is adjusted correctly but continues to fail.
➤ Make sure that the unit’s manual release is not engaged. The unit’s
manual release, when disengaged, will set off the entrapment sensor
if the gate is given a command to move. See page 11.
➤ 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 13.

HYDRAULIC SYSTEM INFORMATION
HYDRAULIC MOTORS
1. The two hydraulic motors are “ROLLER VANE” type and are
machined to be free wheeling. Each motor has a displacement
of 12 in3/rev.
2. The speed of each is approximately 55 RPM which equates to
a gate speed of approximately 18"/ sec. for classes 3 and 4.
For classes 1 and 2, the motor’s speed is 37 RPM and gate
speed of 12"/sec.
3. The drive wheels are: HS670 1HP (1-1/2" w. x 6" dia.) HS670
2HP (2" w. x 6" dia.).
Circumference of both: 18.84"
Both have a hardness of approximately 70 “A” shore.
FLUID
1. If and when adding fluid, use ONLY hydraulic oil.
2. The tank capacity is: one (1) gallon maximum.
3. To measure the fluid in the tank, it is suggested that a ruler be
used like a dip stick. Insert it into the tank until it touches the
bottom, then remove. When tank is full, the fluidmark should
be around six inches.
DO NOT let the fluid level get below 3 to 4 inches.
PUMP
The pump on the HS670 has a built in relief valve. If the P.S.I.
should exceed its factory setting, it will bleed off the excess. The
HS670-100 is set at approximately 600 P.S.I. the HS670-200 is
set at approximately 1500 P.S.I.
1. Both models have a 4 way, 3 position, dual solenoid activated
directional valve. It operates on 24 VDC, with a built-in rectifier
on each solenoid. Reference hydraulic circuit.
2. Both models have a bypass valve with handle. When this valve is
positioned for manual operation, it will redirect the fluid back into
the tank and not through the motors. Reference hydraulic circuit.
3. Both models have a check valve built into the pump. This valve
will not allow fluid to go in the wrong direction. Reference
hydraulic circuit.
HOSES - FITTINGS - THREADS
1. All hoses are: S.A.E. 100 R1, type AT, single wire braid, 3/8"

UNAUTHORIZED REPAIRS OR ANY ALTERATIONS TO THIS PRODUCT), LABOR CHARGES FOR REINSTALLING A REPAIRED OR
