CLASS II – COMMERCIAL/GENERAL ACCESS VEHICULAR GATE OPERATORA vehicular gate operator (or system) intended for use in a commercial location or building such as amulti-family housing unit (five or more single family units) hotel, garage, retail store or other buildingservicing the general public.
CLASS III – INDUSTRIAL/LIMITED ACCESS VEHICULAR GATE OPERATORA vehicular gate operator (or system) intended for use in a industrial location or building such as afactory or loading dock area or other location not intended to service the general public.
CLASS IV – RESTRICTED ACCESS VEHICULAR GATE OPERATORA vehicular gate operator (or system) intended for use in a guarded industrial location or building suchas an airport security area or other restricted access locations not servicing the general public, in whichunauthorized access is prevented via supervision by security personnel.
SAFETY ACCESSORY SELECTIONAll UL325 compliant LiftMaster gate operators will accept externalentrapment protection devices to protect people from motorizedgate systems. UL325 requires that the type of entrapmentprotection correctly matches each gate application. Below are thesix types of entrapment protection systems recognized by UL325for use on this operator.
ENTRAPMENT PROTECTION TYPESType A: Inherent obstruction sensing system, self-contained
within the operator. This system must sense and initiatethe reverse of the gate within two seconds of contactwith a solid object.
Type B1: Connections provided for a non-contact device, such asa photoelectric eye, can be used as a secondaryprotection.
Type B2: Connections provided for a contact sensor. A contactdevice, such as a gate edge, can be used for secondaryprotection.
Type C: Inherent adjustable clutch or pressure relief valve.Type D: Connections provided for a control
requiring continuous pressure tooperate the operator open and close.
Type E: Built-in audio alarm. Examplesinclude sirens, horns or buzzers.
NOTE: UL requires that all installations musthave warning signs placed in plain view onboth sides of the gate to warn pedestrians ofthe dangers of motorized gate systems.
UL325 ENTRAPMENT PROTECTION REQUIREMENTS
The chart above illustrates the entrapment protectionrequirements for each of the four UL325 classes.In order to complete a proper installation you must satisfy theentrapment protection chart shown above. That means thatthe installation must have one primary means of entrapmentprotection and one independent secondary means ofentrapment protection. Both primary and secondaryentrapment protection methods must be designed, arrangedor configured to protect against entrapments in both the openand close directions of gate travel.For Example: For a slide gate system that is installed on asingle-family residence (UL325 Class I) you must provide thefollowing: As your primary type of entrapment protection youmust provide Type A inherent (built into the operator)entrapment sensing and at least one of the following as yoursecondary entrapment protection: Type B1- Non-contactsensors such as photoelectric eyes, Type B2- Contact sensorssuch as gate edges or Type D- Constant pressure control.

1. Vehicular gate systems provide convenience and security. Gate systems are comprised of many component parts. The gateoperator 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 individualapplication. Improperly designed, installed or maintained systems can create risks for the user as well as the bystander. Gatesystems 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 featuresmust 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 swing 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" (57.15 mm) diameter sphere from passing through the openings anywhere in the gate, and inthat 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 accessopening.
6. The gate must be installed in a location so that enough clearance is supplied between the gate and adjacent structures whenopening 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 must be far enough from the gate so that the user is prevented from coming in contact with the gate while operating thecontrols.
9. Controls intended to be used to reset an operator after 2 sequential activations of the entrapment protection device or devicesmust be located in the line of sight of the gate, or easily accessible controls shall have a security feature to prevent unauthorizeduse.
10. All warning signs must be installed where visible, on each side 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. 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.b. 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 buildingstructures, natural landscaping or similar obstruction. A wireless contact sensor shall function under the intended end-useconditions.
c. One or more contact sensors shall be located at the leading edge, trailing edge and post mounted both inside and outside of avehicular horizontal slide gate.
d. One or more contact sensors shall be located at the bottom edge of a vehicular vertical lift gate.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 sensorsshall be located on the bottom edge.

SAFETY PRECAUTIONS FOR OPEN ROLLER GATES
• Injuries occur when people get their hands or feet caughtbetween the top or bottom of the gate and the gate roller.These potential pinch-points should be guarded against at alltimes. Enclosed style gate tracks are available for refitting ofthese rollers from many fence suppliers. Also, roller guardsare available for installing over the rollers.
• UL325 requires that, when used, contact sensors shall belocated at the leading edge, trailing edge, and be postmounted both inside and outside of a vehicular horizontalslide gate. Non-contact sensors such as photo eyes mustprotect during both open and close gate cycles.
• Injuries occur when people put their hands and armsthrough openings in the grill while the gate is operating.They cannot retract their arm and it gets caught between themoving gate grill and the stationary fence post or fence. Thispotential hazard can be averted by placing a 4' (1.2 m)screen mesh on the gate to prevent access through openingsanywhere the gate may travel. See Safety Brochure fordetails. To prevent entrapment injuries, mount controls atleast 6' (1.8 m) from the gate or any moving parts of thegate.

2. Remove the operator cover.3. Locate and engage the manual disconnect and lock it in place
(refer to page 14).4. Connect chain take-up bolt to the end of the chain and attach
to the rear gate bracket (Figure 2).5. Ensure that the drive and idler sprockets are in line with each
other. Thread the chain through the plastic chain guide, arounddrive and idler sprockets, and then through the second plasticchain guide toward front gate bracket (Figure 3).
6. Adjust the chain to proper length and attach second take-upbolt to chain end. Secure the take-up bolt to the front gatebracket as shown.
Adjust nuts on chain take-up bolts to remove chain slack. Ageneral rule of thumb is to leave a maximum of 1" of chain slackfor every 10' of chain length.Do not overtighten chain.
NOTE ABOUT SOME TYPES OF CANTILEVER GATES: With some cantilever gates over 20' long, you may need to add abrace along the length of the gate to prevent the gate frombowing when chain is tightened. This may also be required onsome styles of gates that are constructed out of aluminum. Ifpositioned properly, this brace can also be used as a chainsupport.

NOTE: Normally the hall effect sensor does not need adjustment,but may go out of alignment due to shipping vibration or roughhandling.These operators use an internal entrapment protector system.This system consists of the GL control board, magnet, and HallEffect sensor. It may become necessary to adjust the sensor forcorrect alignment. To do so please perform the following steps:1. The sensor must be
centered over the magnetwheel. Adjust withhorizontal screws.
2. The sensor must belevel.
3. The sensor air gapshould be adjusted to.010 - .015 of an inch.(The thickness of abusiness card may beused to gauge thecorrect distance.) Adjustwith vertical screws.

GATE SYSTEM TEST PROCEDURES
Make sure that the gate’s path is clear from any obstructions and that all associated gate hardware is properly mounted andsecured.1. With the power off, manually move the gate to the fully closed position.2. At the closed position, turn the power on and observe the GL controller board’s diagnostic and limit LEDs. When power is turned
on, these LEDs should flash simultaneously for a few seconds.3. Locate the 3-button control that is built into the electrical box.4. Push the open button and observe the operator’s behavior. The gate should begin opening. If the operator fails to open or has
difficulty opening, refer to the troubleshooting section.5. Once at the open limit, the gate will stop. Push the close button and observe the operator’s behavior. If the operator fails to close or
has difficulty closing, refer to the troubleshooting section.6. While the gate is closing, push the stop button. The gate should now stop.7. Push the close button to return the gate to the fully closed position.

STOP/RESET AUXILIARY CONTROL WIRING (CONTINUED)Terminals 7 & 5 (Com) - Open Override Control InputThese terminals are intended for use only with the open controlof a three-button station that is installed within line of sight of thegate. A momentary activation of this input will cause the gate toopen. Activation of this input for longer than three seconds willenable the control to be used as a constant pressure overridedevice. This will allow the user, in emergencies, to override afailed accessory such as a loop detector or photo-eye.Terminals 4 & 5 (Com) - Close Override Control InputThese terminals are intended for use only with the close controlof a three-button station that is installed within line of sight of thegate. A momentary activation of this input will cause the gate toclose. Activation of this input for longer than three seconds willenable the control to be used as a constant pressure overridedevice. This will allow the user, in emergencies, to override afailed accessory such as a loop detector or photo-eye.Terminals 8 & 5 (Com) - Interrupt (Safety) Loop InputThese terminals are intended for use with a loop detector. Thisinput 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 InputThese terminals are intended for use with a loop detector and isprimarily used on swing gate operators. This input protects carsby preventing the gate from moving off of the open or close limitwhen the shadow loop input is active.The GL operator controller board senses commands using+24VDC from terminal #3. Commands are seen when +24VDC areapplied to the controller’s input terminals. NOTE: The GLcontroller has built in surge suppression circuitry however pleasetake precautions when adding any additional surge protection.
MASTER/SECOND SYSTEMSDual Gate CommunicationsThe controller is capable of running the operator in a master orsecond mode depending on (S4) switch setting.Before initiating any command, the master unit queries for thepresence of a “second unit” for a time period of one second. Ifthe master gets no response the operator will operate in a standalone mode. NOTE: For single unit applications, a jumper must beplaced between 11 and 12 of the field wiring terminal block. Inthis mode no further communications will take place duringtravel. If the master detects the presence of a second unit, themaster will continue to query the second unit during travel. Thesecond unit will send a response to the master for every query.The second operator will stop if there is a period of one secondor more of no communications.When two operators are connected in dual gate configurationaccessories may be connected to either the master or second.NOTE: Do not run Master/Second communication wiring in thesame conduit as the power and control wiring. The second unitwill require a normally close stop circuit for proper systemoperation. After Master/Second wiring has been completed andthe S4 switch programmed, both units must have their powercycled to initiate proper Master/Second communication. Themotor learn function must be completed in stand alone modeprior to Master/Second wiring.

SAMS OPERATION1. When an authorized vehicle accesses the gate system, the
SAM system responds by first opening the gate farthest fromthe vehicle, the swing or slide gate.
2. Once the swing or slide gate is open, the barrier gate beginsits open cycle.
3. Once the barrier is open the vehicle may pass through theSAM system. At this point you have two options in how youwould 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 orb) 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 andallow the vehicle to pass through the SAM system.
6. If another authorized vehicle accesses the SAM system duringthe slide or swing gates closing cycle the SAM system willreopen the slide or swing gate. Once the slide or swing gatereaches the open position the barrier will then open to allowthe vehicle to pass through the SAM system.
7. If no other authorized vehicles access the SAM system theswing or slide gate will close followed by the barrier.
SEQUENCED ACCESS MANAGEMENT SYSTEM (SAMS)The Sequenced Access Management System or SAMS allows the customer more control when managing vehicular entrances to areassuch as apartment complexes, businesses and gated communities. The basic concept of the system is that traffic is controlled by twogates installed in tandem, a fast moving gate such as a barrier gate operator and a slower moving more secure or ornamental gatesuch as a single or pair of slide/swing gate operator. The design of this gate system balances the demands of speed during high trafficperiods with security during low traffic periods. Barrier gates typically have the fastest open times of the many gate operator types andthe 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 gateopen during high traffic times, connect the device’s N/O relay output to the GL board’s Interrupt Loop input. Once the device activatesthe 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 WIRING1. Install conduit between the BG770 and the SL575 for SAMS
control wiring.2. Run a 4-conductor cable in the conduit between the BG770
SL575.3. Locate the SAMS relay terminals (J5) on the GL board in the
SL575 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 5 of the SL575 accessory wiring
terminal block to the common (COM) on the auxiliary limitswitch in the barrier gate.
7. Attach a wire from terminal 8 of the SL575 accessory wiringterminal block to the normally open (NO) on the auxiliary limit switch.
8. Test for correct functionality of the SAM system.

GL BOARD PROGRAMMING AND FEATURES
MOTOR LEARN FUNCTION (FORCE PROFILE)This function is preprogrammed at factory. If either board ormotor 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 forcecontrol. Failure to do so may result in improper and unsafeoperation.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 shaftmust be turning during learn sequence.)
2. Press the motor learn button. The yellow LED should start toflash rapidly.
3. Push and hold down either the open or the close buttons. Themotor will run for a few seconds and then stop. If the LEDgoes out the motor is learned. If the unit activates a limitbefore completing the learn or some other error occurs theLED will go back to on continuously. If this happens trylearning while running in the opposite direction.
4. Reconnect the unit to the gate, reset the limits and adjust theforce 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 terminalsTB1-3 and TB1-5 of the Terminal Strip.
➤ If the yellow LED blinks six times, there is a master/second unitcommunication failure. If operator is a single unit, make sure there isa jumper across terminals TB1-11 and TB1-12. If operator is in a dualgate configuration, make sure that the communication wiring betweenthe two units is undamaged and complete.
➤ If the yellow light is solid, the board needs to learn the motor. Followthe directions on page 23.
➤ If any red LEDs are on, check the corresponding input. An installedaccessory may be wired incorrectly or malfunctioning. Remove theaccessory and test the operator.
➤ If the open or interrupt loop LED is on, make sure factory plug-in loopdetectors are working properly and appropriate loops are installed onthe loop input terminals.
➤ Stand-Alone Operators: Make sure there is a jumper installed acrossthe J4 connector.
➤ Master/Second Operation: Make sure that the master/second wiring isinstalled correctly and is intact (not damaged).
➤ Measure the incoming voltage at the unit’s on/off switch. It should bewithin 5% of the operator’s rating when running. Make sure that theproper wire gauge was used for the distance between breaker andoperator by consulting the wiring specifications section on page 8 ofthis manual.
➤ Measure the voltage at terminals R1 and R2 in the operator. Thisvoltage should be within 5% of 24VAC. If the high voltage power isgood and the low voltage power is bad, check to make sure the circuitfuse is not tripped and that the correct primary tap is used on thetransformer. If fuse and tap are correct, replace the transformer.
➤ If both primary and secondary power is good, check to make surethat the J2 connector is making good contact with the pins on the GLboard. If all is good, replace GL board.

➤ Perform a visual inspection of the motor. Examine the motor’s labelsfor any distortion or signs of overheating. Replace the motor if it ishumming, grinding or making excessive noise. Note: Repeated motorproblems indicate poor primary power.
➤ Examine the contactor for sparking, smoke or burn marks. Removethe wires from one side of the contactor, then measure the contactpoints for high resistance (above 1 ohm). Relace the contactor.
➤ Make sure that the brake is disengaging when the contactor pulls inand engaging when the contactor releases. Replace solenoid.

1) Failure to cycle power after setup
2) Communication wiring may bedamaged or improperly wired for dualgate operation
3) Master or second unit is notprogrammed correctly
T R O U B L E S H O O T I N G
➤ The power to each unit must be cycled in order to initiate propermaster/second communication if the operators were previously instand-alone mode.
➤ Make sure that the communication wire that is used is twisted pairand not run in the same conduit with any power wiring. Failure to doso will result in interference across the master/secondcommunication line.
➤ Review program settings page 20 and check both the master andsecond for proper programming.
1) Operator’s main power is out of phase(three phases only)
➤ Turn off the unit’s main power at the breaker and swap any twopower leads at the operator’s main power switch. Apply power andretest the operator. See important note on page 13.
1) Entrapment (force pot) incorrectly set
2) Gate is binding or not runningsmoothly
3) Clutch is not adjusted properly
4) Brake is not functioning properly
5) Observe red LEDs D29 and D31
6) Hall Effect Sensor is not aligned
➤ This pot must be set so that the gate will run smoothly normally andreverse when encountering an obstruction.
➤ Disengage the manual release and roll gate open and close by hand atnormal operating speed. Make sure that the gate runs smoothly anddoes not bind. If the gate is hard to move or binds, repair the gate.
➤ Adjust the clutch so that the operator can move the gate throughoutits travel without slipping but will slip when the gate hits anobstruction.
➤ Make sure that the brake operates correctly. The brake shoulddisengage when the contactor activates and engage when thecontactor releases.
➤ Both LEDs will indicate the activation of entrapment protectiondevices on terminals TB1-9 and TB1-10 on the GL board. Remove thedevices and retest. If the operator now runs without fault, checkthose accessories as well as their wiring.
➤ Make sure that the sensor is adjusted so that it is centered over thelimit shaft’s magnet and is 10-15 thousandths of and inch (businesscard thickness) from the magnet.
➤ Replace the sensor if it is adjusted correctly but continues to fail.
1) Clutch is not adjusted properly
2) Operator’s manual release is notaligned
➤ Adjust the clutch so that the operator can move the gate throughoutits travel without slipping but will slip when the gate hits anobstruction.
➤ Make sure that the unit’s manual release is not engaged. The unit’smanual release, when engaged, will set off the entrapment if the gateis given a command to move.
1) Active or malfunctioning accessorycheck the red input status LEDs,D11-D13
➤ If any red LEDs are on, check the corresponding input. An installedaccessory may be wired incorrectly or malfunctioning. Remove theaccessory and test the operator.
➤ If the soft open or interrupt loop LED is on, make sure factory plug-inloop detectors are working properly and appropriate loops areinstalled on the loop input terminals.
1) Operator’s manual release is engaged ➤ Make sure the the unit’s manual release is not engaged. The unit’smanual release, when engaged, will not allow the entrapment sensorto provide feedback to the GL board when the operator is moving.
1) Check the save switch on switch S1-1 ➤ If the switch S1-1 is in the on position, any subsequent programmingchanges 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 isprogrammed incorrectly
➤ The open obstruction input has been programmed to function withphoto eyes, not gate edges. Refer to page 16 and reprogram theobstruction inputs for correct operation.
1) Close obstruction input isprogrammed incorrectly
➤ The close obstruction input has been programmed to function withgate edges, not photo eyes. Refer to page 16 and reprogram theobstruction inputs to match the accessories that are installed onoperator.
