SAFETY INFORMATION
GATE OPERATOR CLASSIFICATIONS
All gate operators can be divided into one of four different
AND WARNINGS
Read the following before beginning to install LINEAR barrier
gates:
classifications, 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.
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.
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 five
or more single family units, hotel, retail store or other building
servicing the general public.
3. Barrier gate operators are for vehicular traffic only.
Pedestrians must be supplied with a separate access
opening.
4. Never reach between, through or around the fence to
operate the gate.
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.
5. You must install all required safety equipment.
PRE-INSTALLATION
INFORMATION
Before unpacking, inspect the carton for exterior damage.
If you find damage, advise the delivery carrier of a potential
claim.
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.
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.
LINEAR barrier gate operator models BGU and BGU-D
meet the requirements for all four classifications.
Before installing the operator, read this manual completely
to ensure all requirements for proper installation are present.

WIRING SPECIFICATIONS
1. Select from the chart at the bottom of this page
corresponding to the model, voltage and horsepower
rating of your operator.
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.
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.
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.
3. When large-gauge wire is used, a separate junction box
(not supplied) may be needed for the operator power
connection.
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.
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.
USE COPPER WIRE ONLY!

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.
OR
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.
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.
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
qualified electrician.
Always disconnect power from operator before servicing.
Keep clear of gate arm during operation.
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 specifications 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.

OR DAMAGE MAY RESULT!
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 configure 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 configuration. Operators which are stand-alone or master units should be set to OFF, while
only slave units should have this switch set to ON.

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.
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!

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. Afactory 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 fine 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 cur-
rent 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.

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 first place!

MODEL BGUS/BGUS-D • SG/SG-D OPERATOR INSTALLATION GUIDE
TROUBLESHOOTING
Operator fails to start:
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.
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.
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. 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).
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.
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.
Gate staying open with automatic system:
Limit switch getting out of time:
A. Check the setscrews in limit cams and limit sprockets for
tightness. Replace if necessary.
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)
B
or yearly, whichever comes first. 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.

MODEL BGUS/BGUS-D • SG/SG-D OPERATOR INSTALLATION GUIDE
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 fittings, 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.
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.
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.
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.
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.
9. Check current sensing for proper adjustment when finished
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.
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.
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 fix as required. Failure to
keep the gate in good working condition will have
adverse effects on the operator.

composition). Toxic gases will form upon combustion.
FIRE FIGHTING: Use water spray to cool fire exposed surfaces and to protect person-
nel. Shut off fuel to fire.
Use foam, dry chemical or water spray to extinguish fire. Respiratory and eye protection
required for fire fighting personnel. Avoid spraying water directly into storage contain-
ers due to danger of boilover. A self-contained breathing apparatus (SCBA) should be
used for all indoor fires and any significant outdoor fires. For small outdoor fires, which
may easily be extinguished with a portable fire extinguisher, use of an SCBA may not
be required.

OCCUPATIONAL EXPOSURE LIMIT:
ACGIH recommends: For oil mists, 5 mg/m3. Local regulated limits may vary.
5. FIRST AID MEASURES
INHALATION: Vapour pressure of this material is low and as such inhalation under nor-
mal conditions is usually not a problem. If overexposed to oil mist, remove from further
exposure. Administer artificial respiration if breathing has stopped. Keep at rest. Call for
prompt medical attention.
EYE CONTACT: Flush eyes with large amounts of water until irritation subsides. If irrita-
tion persists, get medical attention.
SKIN CONTACT: Flush with large amounts of water. Use soap if available. Remove
severely contaminated clothing (including shoes) and launder before reuse. If irritation
persists, seek medical attention.
INGESTION: If swallowed, DO NOT induce vomiting. Keep at rest. Get prompt medical
attention.
6. PREVENTIVE AND CORRECTIVE MEASURES
PERSONAL PROTECTION: The selection of personal protective equipment varies,
depending upon conditions of use. In open systems where contact is likely, wear safety
goggles, chemical-resistant overalls, and chemically impervious gloves. Where only
incidental contact is likely, wear safety glasses with side shields. No other special pre-
cautions are necessary provided skin/eye contact is avoided. Where concentrations in
air may exceed the occupational exposure limits given in Section 4 and where engineer-
ing, work practices or other means of exposure reduction are not adequate, approved
respirators may be necessary to prevent overexposure by inhalation.

ENGINEERING CONTROLS: The use of local exhaust ventilation is recommended to
control emissions near the source. Laboratory samples should be handled in a fume-
hood. Provide mechanical ventilation of confined spaces.
