UL325 MODEL CLASSIFICATIONS

The SW470 and SW490 are intended for use with vehicular swing gates. The opener can be used in Class I, Class II, Class III and Class IV applications.

CLASS I – RESIDENTIAL VEHICULAR GATE OPERATOR

A vehicular gate operator (or system) intended for use in a home of one-to four single family dwellings, or a garage or parking area associated therewith.

CLASS II – COMMERCIAL/GENERAL ACCESS VEHICULAR GATE OPERATOR

A vehicular gate operator (or system) intended for use in a commercial location or building such as a multi-family housing unit (five or more single family units) hotel, garage, retail store or other building servicing the general public.

CLASS III – INDUSTRIAL/LIMITED ACCESS VEHICULAR GATE OPERATOR

A vehicular gate operator (or system) intended for use in a industrial location or building such as a factory or loading dock area or other location not intended to service the general public.

CLASS IV – RESTRICTED ACCESS VEHICULAR GATE OPERATOR

A vehicular gate operator (or system) intended for use in a guarded industrial location or building such as an airport security area or other restricted access locations not servicing the general public, in which unauthorized access is prevented via supervision by security personnel.

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 six types of entrapment protection systems recognized by UL325 for use on this operator.

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

photoelectric 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.

NOTE: UL requires that all installations must have warning signs placed in plain view on both sides of the gate to warn pedestrians of the dangers of motorized gate systems.

The chart above illustrates the entrapment protection requirements for each of the four UL325 classes.

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 photoelectric eyes, Type B2- Contact sensors such as gate edges or Type D- Constant pressure control.

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).

2. Remove the open stop, as it is not to be used in this application. Use any existing hardware necessary to seal the open stop’s hole in the operator’s cover.

3. Measure the length of the gate panel and select the appropriate extension arm (x) and control arm (Y) dimensions from the gate installation table.

4. Install the control arm hub assembly to the operator’s output shaft. Make sure that the key is properly inserted into the hub assemblies keyway. Lock the key in place with using the set screw provided in the hub.

5. Attach control arm extension to control arm hub assembly by bolting or welding the two pieces together to achieve the proper control arm dimension (Y).

6. Determine the proper location of the gate bracket by measuring the gate panel’s length and referring to the gate installation table (Dimension B) on the next page. Install the supplied gate bracket or install your own gate bracket (recommended 2" x 2" x 1/4" angle) horizontally on the gate and at the same height as the top surface of the control arm extension. Secure the gate bracket to the gate by either welding or bolting the bracket to the gate.

7. Assemble one extension arm holder to the gate bracket using supplied hardware (Figure 2).

8. Assemble the other extension arm holder to the control arm extension using the supplied pivot pin assembly and cotter pin (Figure 3).

9. Measure and cut pipe (not provided) and position the pipe into the extension arm holders to achieve the proper extension arm dimension (X). Insert the hex head set screws in each extension arm holder in order to hold pipe firmly. Do not tighten until testing and all final adjustment have been completed (Figure 4).

PROGRAMMING THE RADIO RECEIVER

SET SECURITY MODE

The Universal Receiver can be used with up to 15 315 MHz rolling code remote controls or PINs in HIGH security mode. Alternately, it can be used with up to 31 of any type 315 MHz remote control in NORMAL security mode, including any combination of rolling code, billion code, or dip switch remotes.

The jumper must be set at the HIGH position for the receiver to operate in HIGH security mode. It must be set at NORMAL position to operate at the NORMAL mode (Figure 1).

When changing from NORMAL to HIGH security mode, any previous remote control codes must be erased. Repeat Steps 2 and 3 in the Programming Section below to reprogram the receiver for each remote control in use.

The receiver is factory set at HIGH.

To prevent possible SERIOUS INJURY or DEATH, the use of CONSTANT OPERATION on residential openers is

PROHIBITED.

To prevent possible SERIOUS INJURY or DEATH from electrocution:

• Be sure power is not connected BEFORE installing the receiver.

To prevent possible SERIOUS INJURY or DEATH from a moving gate or garage door:

• ALWAYS keep remote controls out of reach of children. NEVER permit children to operate, or play with remote control transmitters.

• Activate gate or door ONLY when it can be seen clearly, is properly adjusted, and there are no obstructions to door travel.

• ALWAYS keep gate or garage door in sight until completely closed. NEVER permit anyone to cross path of moving gate or door.

NOTICE: To comply with FCC and or Industry Canada (IC) rules, adjustment or modifications of this receiver and/or transmitter are prohibited, except for changing the code setting or replacing the battery. THERE ARE NO OTHER USER SERVICEABLE PARTS.

Tested to Comply with FCC Standards FOR HOME OR OFFICE USE. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.

SET OUTPUT DURATION

For commercial applications, the receiver can be set for either constant or momentary closure on the output contacts. Use of constant closure is prohibited on residential garage door openers because it overrides the safety reversal devices.

With the jumper in the “M” (Momentary) position, the contacts will close for 1/4 second regardless of the length of radio transmission. With the jumper in “C” (Constant) position, the contacts will stay closed as long as the radio continues transmitting (Figure 2).

1. Before turning on power, disconnect extension arm from gate bracket so gate is no longer connected to operator. Push manual release pin(s) up through the control arm, slide clevis pin in place and secure with a cotter pin.

2. The (3) collars are held to shaft by set screws. The collars should now be loose on the shaft. If not, loosen all set screws until collars are moving freely on shaft.

When following limit switch adjustment procedure, the motor belt will turn and the control arm will move during some steps. Keep hands and tools out of operator and away from arm and drive shaft unless power is off or SERIOUS INJURY

may occur.

TO ADJUST CLOSE LIMIT SWITCH

3. Turn on electrical power.

4. Press CLOSE button (if installed) or connect terminals 4 & 5 on J1 terminal strip to cause the gate to close. The control arm should move in the close direction.

5. When control arm is pointed in approximate direction of gate bracket (on fully closed gate) press STOP button or release terminals to stop control arm.

NOTE: If control arm does not move far enough to point in proper direction, the close limit switch has been prematurely actuated. Turn off power, loosen set screw on close limit cam and rotate nut away from close limit switch. Repeat steps 3 and 4 until control arm is pointed in correct direction.

6. Turn off power. Be sure close limit cam is freely turning. Rotate cam in close direction. Stop when cam just clicks close limit switch. Tighten set screw.

7. Reconnect gate bracket to extension arm. If arm has moved too far in close direction to allow connection of gate bracket turn off power, connect terminals 5 & 7 to rotate arm in opposite direction, and press STOP button when arm is in desired position.

TO ADJUST OPEN LIMIT SWITCH

8. Turn on power. Press OPEN button (if installed) or connect terminals 5 & 7 on J1 terminal strip. Gate should open. If gate does not open the open limit cam may be already actuating open limit switch or an improper electrical connection may have been made. Turn off power, inspect, correct and repeat this step.

9. When gate reaches desired fully open position press STOP button or release terminals. Turn off power. Limit cam should turn freely. Rotate cam in open direction. Stop when cam just clicks the open limit switch. Tighten set screw.

10. Fine tune both switch settings by using J1 terminals 4 & 5

RPM SENSOR (HALL EFFECT) ADJUSTMENT

NOTE: Normally the RPM sensor (hall effect) 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 RPM sensor. It may become necessary to adjust the sensor for correct alignment. To do so, please perform the following steps:

1. Loosen the two screws holding the hall bracket to the frame.

2. Adjust the bracket so that the sensor is:

a. Parallel with the pulley. b. .020" (.051 cm) away from the pulley's magnet. Use a

feeler gauge to measure the distance.

3. Tighten screws to secure assembly.

4. Manually rotate pulley to ensure that each magnet clears the

sensor board.

If a magnet does not clear the board, re-adjust the RPM (hall effect) assembly accordingly.

To reduce the risk of SEVERE INJURY or DEATH:

• Disconnect power BEFORE performing ANY adjustments.

SEQUENCED ACCESS MANAGEMENT SYSTEM (SAMS)

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 slide or swing gate open during high traffic times, connect the device’s N/O relay output to the control 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.

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 SW420 for SAMS control wiring.

2. Run a 4-conductor cable in the conduit between the BG770 SW420.

3. Locate the SAMS relay terminals (J5) on the control board in the SW420 and locate the auxiliary limit switch in the BG770.

4. Attach a wire from the SAMS relay terminal (J5) on the control board to terminal 1 on the BG770 terminal strip.

5. Attach a wire from the SAMS relay terminal (J5) on the control board to terminal 3 on the BG770 barrier gates terminal strip.

6. Attach a wire from terminal J1-5 on the control board to the common (COM) on the auxiliary limit switch in the barrier gate.

7. Attach a wire from terminal J1-8 on the control board to the normally open (NO) on the auxiliary limit switch.

8. Test for correct functionality of the SAM system.

CONTROL BOARD 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 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 alone mode.

1. The operator must remain attached to the gate throughout the entire process.

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.

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.

DIAGNOSTICS (LEDS AND CODES)

There are three diagnostic LEDs. Two red LEDs (OLS, CLS) are indicators for the open and close limits. The LEDs are illuminated when the limit switch contacts are closed.

The third amber LED (DIAG) 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.

EDGE/PHOTO OPEN

This switch (S2-3) selects edge or photo sensor for the gate opening protection input.

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.

EDGE OPEN PHOTO OPEN

(Factory Default)

MASTER/SECOND SYSTEMS Dual Gate Communications

The control board 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 pins 1 and 2 of the J4 connector. 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.

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.

EDGE CLOSE PHOTO CLOSE

(Factory Default)

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. The Second unit will require a normally close stop circuit for proper system operation. 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. The motor learn function must be completed in stand alone mode prior to Master/Second wiring.

TROUBLESHOOTING

SYMPTOM POSSIBLE CAUSES SOLUTION

Operator fails to run.

No Stop Control. Check the green LED (D17) on control board. If the green LED is off,

check to make sure a stop control has been installed across terminals J1-3 & J1-5 of the control board.

Fault in the operator. Check the yellow diagnostic LED at the top right of the control board next to the programming dip switches.

An accessory is active or malfunctioning. Check the red input status LEDs, D11-D31.

Improper J4 Connector Wiring (Master/Second).

Low or no high voltage power. Measure the incoming voltage at the unit’s on/off switch. It should be

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 J4 pins 1 & 2. 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 24.

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.

Stand-alone Operators: make sure there is a jumper installed across the J4 connector.

Master/Second Operation: Make sure that the master/second wiring is installed correctly and is intact (not damaged).

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 14 of this manual.

The relays chatter when the operator begins to move.

The operator runs slow and/or trips the internal overload.

Motor runs but gate does not move.

Low or no low voltage power. Measure the voltage at terminals R1 & R2 in the operator. This

voltage should be within 5% of 24 Vac. If the high voltage power is good and the low voltage power is bad, check transformer wiring and replace transformer.

No LEDs illuminated on the control board.

Low secondary (low voltage) power. Measure the voltage at terminals R1 & R2 in the operator. This

Low primary (high voltage) power. Measure the incoming line voltage at the unit’s on/off switch as well

Problem in the motor. Perform a visual inspection of the motor. Examine the motor’s labels

Damaged or improperly tensioned belt/drive chain.

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 board. If all is good, replace the control board.

voltage should be within 5% of 24 Vac. If the high voltage power is good and the low voltage power is bad, check to make sure the circuit breaker is not tripped and that the correct primary tap is used on the transformer. If breaker and tap are correct replace the transformer.

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 15 of this manual.

for any distortion or signs of over heating. Replace the motor if it is humming, grinding or making excessive noise. NOTE: Repeated motor

problems indicate poor primary power.

Make sure that the operator’s belt/drive chain is intact and tensioned correctly.

TROUBLESHOOTING continued

SYMPTOM POSSIBLE CAUSES SOLUTION

Master or Second operator is not functioning properly.

Operator runs but then stops and reverses direction.

The operator opens immediately upon power up and does not close.

Programming changes do not effect the gate.

Open photo eye reverses gate closed when activated during opening.

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.

The communication wiring may be damaged or improperly wired for dual gate operation.

The master or second unit is not programmed correctly.

Entrapment (Force Pot) incorrectly set. This pot must be set so that the gate will run smoothly normally and

Gate is binding or not running smoothly.
