MODEL BGUS/BGUS-D • SG/SG-D OPERATOR INSTALLATION GUIDE

GATE OPERATOR CLASSIFICATIONS

All gate operators can be divided into one of four different classiﬁ cations, depending on their design and usage.

Class I Residential Vehicular Gate Operator

A vehicular gate operator intended for use in a home of one to four single family dwellings, or garage or parking area associated with these dwellings.

Class II Commercial / General Access Vehicular Gate Operator

A vehicular gate operator intended for use in a commercial location or building such as a multifamily housing unit of ﬁ ve or more single family units, hotel, retail store or other building servicing the general public.

Class III Industrial / Limited Access Vehicular Gate Operator

A vehicular gate operator intended for use in an 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 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.

LINEAR barrier gate operator models BGU and BGU-D meet the requirements for all four classiﬁ cations.

SAFETY INFORMATION

AND WARNINGS

Read the following before beginning to install LINEAR barrier gates:

1. All electrical connections to the power supply must be made by a licensed electrician and must observe all national and local electrical codes.

2. A separate power-disconnect switch should be located near the operator so that primary power can be turned off when necessary.

3. Barrier gate operators are for vehicular trafﬁ c only. Pedestrians must be supplied with a separate access opening.

4. Never reach between, through or around the fence to operate the gate.

5. You must install all required safety equipment.

PRE-INSTALLATION

INFORMATION

Before unpacking, inspect the carton for exterior damage. If you ﬁ nd damage, advise the delivery carrier of a potential claim.

Inspect your package carefully. You can check your accessory box parts with the enclosed packing slip for your convenience. Claims for shortages will be honored for only 30 days from the date of shipment.

Before installing the operator, read this manual completely to ensure all requirements for proper installation are present. Verify that the voltage to be used matches the voltage of the operator.

The following contact or non-contact obstruction detection devices have been approved for use with LINEAR barrier gate operators as part of a UL325 compliant installation:

MODEL BGUS/BGUS-D • SG/SG-D OPERATOR INSTALLATION GUIDE

WIRING SPECIFICATIONS

1. Select from the chart at the bottom of this page corresponding to the model, voltage and horsepower rating of your operator.

2. The distance shown on the chart is measured in feet from the operator to the power source. DO NOT EXCEED THE MAXIMUM DISTANCE. These calculations have been based on standard 115V and 230V supplies with a 10% drop allowable. If your supply is under the standard rating, the runs listed may be longer than what your application will handle, and you should not run wire too near the upper end of the chart for the gauge of wire you are using.

3. When large-gauge wire is used, a separate junction box (not supplied) may be needed for the operator power connection.

4. All control devices are now 24VDC, which can be run considerable distances. 24VAC is available for other devices, such as loop detectors and photo eyes.

5. Wire run calculations are based on the National Electrical Code, Article 430 and have been carefully determined based on motor inrush, brake solenoids, and operator requirements.

6. Connect power in accordance with local codes. The

green ground wire must be properly connected.

7. Wire insulation must be suitable to the application.

8. Control wiring must be run in a separate conduit from power wiring. Running them together may cause interference and faulty signals in some accessories.

9. Electrical outlets are supplied in all 115VAC models for convenience with occasional use or low power consumption devices only. If you choose to run dedicated equipment from these devices, it will decrease the distance for maximum run and the charts will no longer be accurate.

10. A three-wire shielded conductor cable is required to connect master and slave operators. You must use Belden 8760 Twisted Pair Shielded Cable (or equivalent) only – LINEAR part number 2500-1982, per foot). See Page 9 for details of this connection, as well as dip switch selection. Note: The SHIELD wire should be

connected in both the master and slave operators.

MODEL BGUS/BGUS-D • SG/SG-D OPERATOR INSTALLATION GUIDE

VENT PLUG INSTALLATION

Gear reducers used in LINEAR gate operators will have pinned vent plugs installed prior to shipping in order to keep the oil from spilling out during transportation. During installation this pin should be removed to allow proper ventilation. See the illustrations below.

LIMIT CAM ADJUSTMENTS

The limit cams for all models of barrier gate operators have been pre-set at the factory for approximately 90 degrees of motion. If you need to adjust this further, please follow the directions below. If the arm reverses just after you attempt to open it, you may need to adjust the open direction current sensor one turn higher. Refer to Page 9 for details of current sensing adjustment.

ELECTRICAL CONNECTION AND ADJUSTMENTS

Power supply must be of correct voltage and phase. Always follow national and local electrical codes when wiring and use a qualiﬁ ed electrician. Always disconnect power from operator before servicing. Keep clear of gate arm during operation.

1. For more downward travel, loosen the wing nut on the LSC-1 (down) limit cam and rotate the cam slightly in the “B” direction.

2. For less downward travel, loosen the wing nut on the LSC-1 (down) limit cam and rotate the cam slightly in the “A” direction.

3. For more upward travel, loosen the wing nut on the LSO-1 (up) limit cam and rotate the cam slightly in the “A” direction.

4. For less upward travel, loosen the wing nut on the LSO-1 (up) limit cam and rotate the cam slightly in the “B” direction.

All LINEAR gate operators are supplied with a power disconnect switch to turn on and off the power supply available to the operator. Incoming power should be brought into the operator and connected to the labeled pigtails in the disconnect box, following wiring speciﬁ cations on Page 4. A wiring connections print can be found on the inside cover of the operator.

Proper thermal protection is supplied with the operator. The motor contains a thermal overload protector to protect from overheating the motor due to overload or high-frequency operation. This overload will reset automatically after the motor cools down.

Auto Close Timer Adjustment: This 270-degree adjustable potentiometer will signal the operator to close automatically, from the fully

open position, provided no open, reversing or obstruction signals are present. The timer is adjustable from 0 to 124 seconds. This feature is turned off or on using dip switch #1. Maximum Run Timer Adjustment: This 270-degree adjustable potentiometer should be left in the fully clockwise position on all barrier gate operators. Open Direction Current Sense Adjustment: This multi-turn potentiometer is used to calibrate the built-in current sensing feature for detection of obstructions while running in the open direction. Close Direction Current Sense Adjustment: This multi-turn potentiometer is used to calibrate the built in current sensing feature for detection of obstructions while running in the closed direction. Master/Slave Connection Block: This terminal block is used in conjunction with two operators to conﬁ gure two gates to open and close together.

Dip Switches:

#1 This switch turns the auto close timer off/on. #2 This switch controls the behavior of the open/reset function in barrier gates only. When the switch is turned ON, a momentary open/

reset pulse will cause the arm to raise and stay raised until a reset or another open/reset signal occures. In the ON position, this switch also disables the counting function of Dip Switch #4. When the switch is turned OFF, the arm will lower as the open/reset signal is no longer present.

#3 This switch is used in conjunction with single-button controls and radio receivers. In the ON position, successive inputs will cause

signals in the order of OPEN-STOP-CLOSE-STOP. In the OFF position, inputs will cause an OPEN signal unless the gate is fully open, in which case it will signal CLOSE.

#4 In the OFF position, for every open signal the barrier gate receives, there must be a reset signal before the arm will come down. In

the ON position, this feature is disabled.

#5 In the OFF position, if two vehicles are close together and the second vehicle triggers the reset loop as the arm is coming down, the

arm will stop until the second car is clear of the loop, then continue down. In the On position, the arm will continue down even when a second car triggers the reset loop. If the application requires that only a single vehicle pass through at a time, then this featurte should be ON. In all other cases the feature should be left OFF, as the arm will come down onto a tailgating vehicle.

#6 In the ON position, this switch will disable the inherent DC brake in DC operators only. In addition, the R2 brake resistor on the DC

motor board must be cut from the board (refer to the picture above). In the OFF position, the DC brake will function. #7 Not used at this time. #8 This switch is used to set Master/Slave conﬁ guration. Operators which are stand-alone or master units should be set to OFF, while

only slave units should have this switch set to ON.

24VDC+ 24VDC Provides 24Volt DC power for accessories. 24VDC- COMM.

1 & 4 OPEN Opens the operator. Several accessories such as button stations, keypads,

transmitters and card readers can be wired to open.

3 & 4 CLOSE Closes the operator. Use caution when wiring accessories to these terminals. The

gate must be clearly visible from the location of any accessories wired to close.

4 & 5 SINGLE-BUTTON Performs the single-button function which will alternate between open and close

or open, stop and close - depending on dip switch #3. (See Page 9 for details.)

2 & 4 STOP Stops the operator. On barrier gate operators, this button is also the reset

button.

4 & 6 REVERSE This function will cause a reversal when the gate is traveling closed and will travel

back to the fully open position. Loop detectors are often wired for reverse.

4 & 50 OPEN/RESET A signal across these terminals will cause the arm of the barrier gate operator to

raise and stay open until the signal is gone, at which point the arm will immediately begin to come down.

4 & 51 CLOSE This function works only while the arm is coming down. Any signal to this function

4 & 11 RESET This function will cause the arm to come down as soon as the signal clears.

24VDC+ & 60 RUN A 24Volt DC device such as a strobe light or alarm can be wired to these terminals.

You must follow all required safety precautions and instructions at all times. Review the safety brochure included with the operator. If any pages are missing or unreadable, contact LINEAR at 1-800-333-1717 to request additional copies.

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.

will cause the arm to stop and fully reverse.

These devices will be powered while the motor is running. (See Page 9 for details.)

Do not adjust the circuit board current sensing feature too high. It should be adjusted high enough to keep the gate arm from falsely triggering the sensing, but no higher than necessary for the barrier gate to operate. Do not defeat the purpose of this function!

-10-

MODEL BGUS/BGUS-D • SG/SG-D OPERATOR INSTALLATION GUIDE

CURRENT SENSING ADJUSTMENTS

Because gates vary in construction and may have different force requirements in the open and close directions to move, the LINEAR control board has separate Multi-turn potentiometers for adjusting in both directions independently. The adjustment should be set light enough to maintain minimal force (40 lbs.) should an obstruction occur, but high enough to keep the gate moving under normal conditions without interruption.

Prior to adjusting the operator current sensing functions, make sure the gate moves freely in both directions. A badly aligned or poorly maintained gate may cause false triggering of the current sensor. Refer to Page 9 when following the instructions below. A factory adjustment tool has been supplied to make these adjustments easier. This tool has been taped to the control box for your convenience.

CLOSE DIRECTION CURRENT SENSE ADJUSTMENT

When the gate operator leaves the factory, it has been preset for a relatively light gate function and will require additional adjustment. Begin by starting the gate going closed. If the operator stops and reverses, turn the close direction potentiometer (see Page 9) one turn higher, press the STOP button, and try again. Repeat this process until the gate no longer causes false tripping of the current sensor. Note that each time the gate operator reverses, the STOP button must be pressed. Next, turn the close direction potentiometer lower slowly while the operator is running the gate closed until the gate operator stops and reverses again. From this point, turn the close direction potentiometer higher by 1 1/2 turns for all 115 Volt AC and 24 Volt DC operators, and by 3/4 of a turn higher for all 230 Volt AC operators. Additional ﬁ ne adjustment by 1/4 turns may be necessary to eliminate false triggering.

OPEN DIRECTION CURRENT SENSE ADJUSTMENT

Repeat the same process with the open direction potentiometer while running the gate in the open direction. Once this is done, run the gate through several complete cycles and make sure the gate does not false trip in either direction.

Multi-turn Potentiometer

Remember it is important not to set the adjustment too high! Doing so will defeat the purpose of the current sensing as an obstruction detecting feature.

MAXIMUM RUN TIMER ADJUSTMENT

This adjustment is not used in barrier gate operators and should be turned fully clockwise.

AUTO CLOSE TIMER ADJUSTMENT

This adjustable potentiometer sets the length of time which elapses before the gate operator automatically closes the gate, from the fully open position, provided no open, reversing, or obstruction signals are present. This feature can be turned on or off via dip switch selection. See Page 9 for details. Do not use the auto close timer without an appropriate reversing

device installed!

MASTER/SLAVE CONNECTION

A three-wire shielded conductor cable is required to connect master and slave operators. You must use Belden 8760 Twisted Pair Shielded Cable (or equivalent) only – LINEAR part number 2500-1982, per foot). See Page 9 for details of this connection, as well as dip switch selection. Note: The SHIELD wire should be connected in both the master and slave operators. In

addition, you must run power to both the master and slave operators.

BATTERY CHARGING Indicates batteries are being charged. Light goes out when batteries reach 90% of full charge.

OPEN GATE Operator is in open then lockout stage.

POWER LOCKOUT Flashes when controls/motor are in lockout mode.

SURGE PROTECTOR INSTRUCTIONS

The optional surge protector should be connected to any inputs that have an accessory connected to it. This includes the 3-button station, so it must be connected to 1, 2A and 3 in all cases. The green wire connected to ground, which is electrically the same as terminal 4. The red wires connect to terminals 2A and 24VDC+. This will cause the 2 amp fuse to blow if this section of the module becomes shorted. With any of the other inputs connected to the surge protector, if their protection line becomes shorted due to a surge over the rating of the module, the corresponding LED on the main board will remain lit, causing a constant signal to the controller. If this is found, please replace the entire surge protector with a new unit.

Do not simply unhook the shorted wire, as this removes the protection from the circuit that was saved by the protector in the ﬁ rst place!

CHARGER BOARD SLEEP MODE

When primary AC power is not available, the operator will continue to operate in battery only mode if the charger board is set in its RUN mode (see Battery Backup Charger Conﬁ guration). Accessories wired into the operator will continue to draw power, even when the operator is not opening or closing the gate. This can dramatically reduce the amount of standby time available from the batteries.

To extend the available standby time, the charger board has a “sleep” mode feature which will turn off power to all controls except for any that are wired according to the schematics below. By removing the black jumper cap JP1 located in the upper right hand corner of the charger board this feature can be enabled. After ﬁ fteen minutes of inactivity, all controls except those wired as shown below will turn off. Those wired as shown will continue to have power at all times and will upon activation generate ﬁ rst a “wake” signal that will power all controls back up, and then create either an open signal or single button signal, depending on how the wire jumper shown below is connected.

TROUBLESHOOTING

Operator fails to start:

A. If the operator has been running a large number of cycles,

the motor may have gotten hot and tripped the overload. Allow the motor to cool down and press the overload reset button in bottom of motor.

B. Make sure you have power at the master distribution

panel and that the power has not been turned off.

C. The secondary fuse on the control board may have

blown. Replace the fuse (refer to control box parts lists on Page 27 or Page 28 for part number information).

Motor operates, but gate does not move:

A. Check for broken or worn belts.

B. Check all setscrews on pulleys and sprockets and

tighten them if necessary, and check for keys which may have fallen loose from keyways.

Motor sounds like it is working harder than normal:

A. Make sure the gate is moving freely and without binding

throughout its entire travel.

Limit switch getting out of time:

A. Check the setscrews in limit cams and limit sprockets for

tightness. Replace if necessary.

Gate stopping part way open or closed (but no visible obstruction):

A. The control board may have received a false obstruction

input triggered by current sensing set too low. Make sure the gate moves freely through its entire travel before adjusting the current sensing.

B. The maximum run timer may have counted down and

expired. This can be caused by having the timer set too low, if a chain or belt is broken, or if a sprocket or pulley is slipping. When the timer expires, the gate stops and the stop button must be pressed to reset gate.

C. An obstruction signal from an accessory wired to the

obstruction input may have triggered falsely. Check the control board for lit L.E.D. indicators for any of the following inputs: safety, shadow, open obstruction, close obstruction, stop, etc. If any are lit when the operator should be running, remove all devices hooked to that function and hook them up one at a time and try to run the operator until the problem device is found. Refer to Page 12 for details on the control board indicators.

Gate staying open with automatic system:

A. If there are vehicle detectors in your machine which are

set up for reverse, one of your loops or loop detectors may be sending a false signal. Disconnect the wire harness and try running the operator.

B. An opening or reversing device may be stuck or

malfunctioning. Try disconnecting these devices and hook them back up one at a time and try running the operator until the malfunctioning device is found.

C. Make sure the close limit switch isn’t activated. If it is, the

operator will think the gate is already closed.

HOW TO ORDER REPLACEMENT PARTS

Use the part numbers listed on the following pages. Contact your local LINEAR dealer or distributor to order parts.

1. Supply the model number and serial number of your operator.

2. Specify the quantity of pieces needed and order by part number and name of part.

MODEL BGUS/BGUS-D • SG/SG-D OPERATOR INSTALLATION GUIDE

BATTERY MAINTENANCE

The gel-cell batteries in this operator require no routine maintenance. For assured continued performance, they should be replaced every year.

If power is to be removed for one week or more, disconnect the negative wire from the batteries as this will prevent deep discharging.

Fully charge before use after storage or upon initial installation.

BRUSH REPLACEMENT

Brushes should be inspected every 100,000 cycles, (200,000 for BGU-D) or yearly, whichever comes ﬁ rst. The motor has two brushes, one on each side.

Original brushes are approximately 3/4” long and should be replaced when they are 1/4” long, or sooner. If brushes are allowed to wear beyond this point, permanent damage to the motor may result.

To inspect the brushes, remove retaining cap (A), with straight-blade screwdriver, and carefully pull assembly straight out. Measure remaining brush material (B).

To reinstall, place brush in hold, aligning rounded indentation (C), correctly with motor shaft. Gently push in spring and align contact with oval carrier, push in with retaining cap (D). Hold in place and thread cap into brush carrier. Do not overtighten or cap will crack! Repeat for other brush.

If brushes require replacement, order kit #2510-243.

PREVENTATIVE MAINTENANCE

IMPORTANT!

• Always disconnect power from operator before servicing.

• Keep clear of gate during operation.

GENERAL:

LINEAR gate operators are designed for many years of trouble-free operation and, under recommended operating conditions, will require only minimal maintenance. To ensure that your unit is ready for operation at all times--and to preclude serious damage or failure--inspect the unit systematically. Proper adjustments and lubrication should be made as recommended.

LUBRICATION: Bearings. For models which have pillow block style bearings with greaseable ﬁ ttings, lubricate at least twice a year with a

lithium complex based, petroleum oil NLGI 2 rated grease. Oilite and precision sealed bearings do not require additional lubrication.

Motor. Motors have sealed ball bearings and do not require further lubrication. If bearing noise develops after several years of operation, bearings should be replaced by a motor repair company, or the motor should be replaced if necessary.

Drive Chain and Sprocket (slide gate models only). The main drive chain and sprockets should be inspected for wear, cleaned, and wiped down with a lightly oiled rag every six months.

Swing Gate Arm (swing gate models only). Check all bolts for proper tension and tighten if necessary. Make sure the arm folds overextends itself slightly against the overtravel stop to reduce the chance that the gate can be backdriven open. Adjust the close limit slightly if additional travel is required. Lightly lubricate all pivot points with a light machine oil.

Barrier Gate Arm (barrier gate models only). Check all bolts for proper tension and tighten if necessary. If the arm has been warped or damaged, replace as necessary.

ADDITIONAL SIX MONTH PREVENTATIVE MAINTENANCE:

1. For operators which utilize torque limiting clutches, check for proper tightness. If there appears to be dust from wear on the pads, inspect the pads and replace if necessary. If the clutch cannot be adjusted tightly enough to move the gate without slipping, the pads must be replaced.

2. For operators with V-belts, inspect for wear and replace as necessary. Check for proper tension and adjust if required. Check all pulley setscrews for tightness and tighten if necessary.

3. For operators with internal chain drives, inspect chain and sprockets for wear and replace if necessary. Check for proper tension and alignment, and adjust if required. Check all hub sprocket setscrews and tighten if required.

4. Check limit switches and limit actuators (cams, limit nuts, etc.) for wear and replace as required. In rotary limit switch assemblies, wipe the limit shaft clean and apply a light coating of dry lubricant.

6. In operators which have a disconnect handle, inspect disconnect handle for proper function and lubricate if necessary. Use a lithium based grease on all moving parts.

7. Inspect all nuts and bolts for proper tightness and tighten as necessary.

8. Check all reversing devices for proper function. Inspect all contact edges for wear and replace if required. Check photo-eyes for proper alignment and function.

9. Check current sensing for proper adjustment when ﬁ nished with inspection and maintenance.

10. Inspect the installation area. Are all the warning signs intact and visible? If they are missing or need replaced, contact LINEAR. Be sure there are no control stations mounted within reach of the gate. Review safety literature with the customer and advise them to remove any such stations found.

5. For operators with magnetic brakes, check for proper adjustment. Brake disc must run free when the brake is engaged. For brake assemblies other than C-face style, the brake should be adjusted so that the solenoid plunger throw is between 3/8” to 1/2”. Too much throw will damage the solenoid. If the solenoid emits a loud

buzzing sound when the motor is run, the brake must be adjusted.

For slide and swing gate operators, you must inspect the gate for proper operation. The gate should move easily without binding through its entire travel. If the gate does bind, adjust or ﬁ x as required. Failure to keep the gate in good working condition will have adverse effects on the operator.
