SAFETY ACCESSORY SELECTION  
UL325 ENTRAPMENT PROTECTION REQUIREMENTS  
GATE OPERATOR ENTRAPMENT PROTECTION  
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  
six types of entrapment protection recognized by UL325 for use  
on this operator.

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 (e.g., sirens, horns or buzzers).  
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.  
NOTES:  
UL requires that all installations must have warning signs

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  
• Screen Mesh  
• Guards for Exposed Rollers  
• Vertical Posts  
• Photoelectric Sensors  
• 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).

Hazard  
• 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.  
Always Test Gate Edges and  
Photo Beams Anytime They Are  
Adjusted or Serviced  
• 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.

Separator Bolt  
(Use 9/16" Socket)  
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.

HALL EFFECT SENSOR ADJUSTMENT  
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:  
WARNING  
To reduce the risk of SEVERE INJURY or DEATH:  
• Disconnect power BEFORE performing ANY adjustments.  
Cover Screws  
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.

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.

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

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  
SAMS WIRING  
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.  
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.

Shadow Loop  
Input  
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  
controller has built in surge suppression circuitry however please  
take precautions when adding any additional surge protection.  
Interrupt (Safety)  
Loop Input  
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.

FAULT  
POSSIBLE CAUSE  
FIX  
OPERATOR FAILS TO RUN  
1) No stop control  
➤ 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.  
2) Fault in the operator check the yellow  
diagnostic LED at the top right of the  
GL board next to the programming dip  
switches.  
➤ 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.  
3) An accessory is active or  
malfunctioning check the red input  
status LEDs, D11-D31  
➤ 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.  
4) Low or no high voltage power.  
5) Low or no secondary voltage power  
6) Improper TB11/TB12 wiring  
(Master/Second)  
➤ 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.  
7) No LEDs illuminated on GL board  
CONTACTOR CHATTERS  
WHEN OPERATOR BEGINS  
TO MOVE  
1) Transformer’s secondary is overloaded ➤ Remove all accessory devices and test the operator. If the contactor  
stops chattering, find an alternate power source for some of the  
devices.  
2) Low primary (high voltage) power  
➤ 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.  
OPERATOR RUNS SLOW  
AND/OR TRIPS THE  
INTERNAL OVERLOAD  
1) Low primary (high voltage) power  
➤ 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.  
2) Problem in the motor  
3) Problem in the contactor  
4) Rail slippage  
➤ 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.

FAULT  
POSSIBLE CAUSE  
FIX  
MASTER OR SECOND  
OPERATOR IS NOT  
FUNCTIONING PROPERLY  
1) Failure to cycle power after setup  
➤ The power to each unit must be cycled in order to initiate proper  
master/second communication if the operators were previously in  
stand-alone mode.  
2) Communication wiring may be  
damaged or improperly wired for dual  
gate operation  
➤ Make sure that the communication wire that is used is twisted pair  
and not run in the same conduit with any power wiring. Failure to do  
so will result in interference across the master/second  
communication line.  
➤ Review program settings on page 18 and check both the master and  
second for proper programming.  
3) Master or second unit is not  
programmed correctly  
OPERATOR RUNS BUT  
THEN STOPS AND  
REVERSES DIRECTION  
1) Entrapment (force pot) incorrectly set ➤ This pot must be set so that the gate will run smoothly normally and  
reverse when encountering an obstruction.  
2) Gate is binding or not running  
smoothly  
➤ Disengage the manual release and roll gate open and close by hand at  
normal operating speed. Make sure that the gate runs smoothly and  
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.  
3) Rail slippage  
4) Brake is not functioning properly  
5) Observe red LEDs D29 and D31  
➤ 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.  
6) Hall Effect Sensor is not  
aligned/adjusted correctly  
➤ 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.  
MOTOR RUNS BUT GATE  
DOES NOT MOVE;  
OPERATOR STOPS AND  
ALARMS  
1) Operator’s manual release is engaged. ➤ 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.  
2) Operator’s main power is out of phase ➤ Turn off the unit’s main power at the breaker and swap any two  
(three phase only).  
power leads at the operator’s main power switch. Apply power and  
retest the operator. See important note on page 13.  
OPERATOR OPENS  
IMMEDIATELY UPON  
POWER UP AND DOES NOT  
CLOSE  
1) Active or malfunctioning accessory  
check the red input status LEDs,  
D11-D13  
➤ 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 soft 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.  
OPERATOR HAS TROUBLE  
LEARNING THE MOTOR  
1) Operator’s manual release is engaged  
➤ Make sure the the unit’s manual release is not engaged. The unit’s  
manual release, when engaged, will not allow the entrapment sensor  
to provide feedback to the GL board when the operator is moving.  
PROGRAMMING CHANGES  
DO NOT EFFECT THE GATE  
1) Check the save switch on switch S1-1 ➤ If the switch S1-1 is in the on position, any subsequent programming  
changes will not affect the gate. To make programming changes,  
switch S1-1 off, make desired changes, and then switch S1-1 on.  
1) Open obstruction input is  
programmed incorrectly  
➤ The open obstruction input has been programmed to function with  
photo eyes, not gate edges. Refer to page 18 and reprogram the  
obstruction inputs for correct operation.  
GATE EDGE PAUSES GATE  
WHEN STRUCK DURING  
OPENING  
1) Close obstruction input is  
programmed incorrectly  
➤ The close obstruction input has been programmed to function with  
gate edges, not photo eyes. Refer to page 18 and reprogram the  
obstruction inputs to match the accessories that are installed on  
operator.

HYDRAULIC SYSTEM INFORMATION  
FLUID  
HYDRAULIC MOTORS  
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.  
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.  
DO NOT let the fluid level get below 3 to 4 inches.  
3. The drive wheels are: HS670 1HP (1-1/2" w. x 6" dia.) HS670  
2HP (2" w. x 6" dia.).  
PUMP  
Circumference of both: 18.84"  
Both have a hardness of approximately 70 “A” shore.  
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.  
HOSES - FITTINGS - THREADS  
1. All hoses are: S.A.E. 100 R1, type AT, single wire braid, 3/8"  
I.D. (Rated working P.S.I. of 2250 and a rated burst P.S.I. of  
9000).  
2. For information on fittings and threads, see page 29.  
3. Both models have a check valve built into the pump. This valve  
will not allow fluid to go in the wrong direction. Reference
