packet of information. If any pages are missing or are unreadable,
or you do not have the safety instructions, please call Linear at
1-800-333-1717 to request additional copies.
3. ALL ELECTRICAL CONNECTIONS TO THE POWER SUPPLY MUST
BE MADE BY A LICENSED ELECTRICIAN AND MUST OBSERVE ALL
NATIONAL AND LOCAL ELECTRICAL CODES.
4. A separate power-disconnect switch should be located near the
operator so that primary power can be turned off when necessary.
5. Never connect a button station within reach of the barrier gate or on
the side of the gate operator.
6. Do not adjust the operator controller’s current sensing feature too
high. It should be adjusted high enough to keep the gate from falsely
triggering the sensing, but no higher than necessary for the gate to
operate. DO NOT DEFEAT THE PURPOSE OF THIS FUNCTION!
7. You must install all required safety equipment.
8. UL325 Compliance requires the use of contact edges or photoelectric
controls on all automatic or remotely-controlled gate operators.
9. The operator is intended for installation only on gates used for

SG •SG-D Barrier Gate Operator Installation Guide - 2 - P1277 Revision X2 8-11-2011
Wiring Specifications
Refer to the following steps for details on power and
accessory wiring for the operator.
AC Power Wiring
1. Find the listing on this page corresponding to the model, voltage and
horsepower rating of your operator.
2. The distance shown in the table is measured in feet from the
operator to the power source. DO NOT EXCEED THE MAXIMUM
DISTANCE. These calculations have been based on standard 115 V
and 230 V 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
maximum distance 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. Wire length calculations are based on the National Electrical Code,
Article 430 and have been carefully determined based on motor
inrush, brake solenoids, and operator requirements.
5. Connect power in accordance with local codes. The green ground
wire must be properly connected.
6. Wire insulation must be suitable to the application.
7. Electrical outlets are supplied in all 115 VAC 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 length and the charts will no
longer be accurate.
DC Control and Accessory Wiring
1. All control devices are now 24 VDC, which can be run up to 2000
feet with 14 AWG wire.
2. Control wiring must be run in a separate conduit from power wiring.
Running them together may cause interference and faulty signals in
some accessories.
3. A three-wire shielded conductor cable is required to connect two
operators together for dual operation. You must use Belden 8760
Twisted Pair Shielded Cable (or equivalent) only – P/N 2500-1982,
per foot). See Page 19 for details of this connection. Note: The shield
wire should be connected in both the operators.
WARNING
ALL AC ELECTRICAL CONNECTIONS TO THE POWER SOURCE AND
THE OPERATOR MUST BE MADE BY A LICENSED ELECTRICIAN
AND MUST OBSERVE ALL NATIONAL AND LOCAL ELECTRICAL
CODES.

Barrier Gate Arm Installation
The barrier gate arm connects to the operator with the arm
attachment channel and gate arm flange. Counterweights
in the attachment channel balance the gate arm for smooth
operation.
✓NOTE: Numbered items in these drawings are for
instructional reference only. For actual part numbers, go
to the parts lists in the back of this booklet.
Attaching the Gate Arm
1. Assemble the SG arm on the ground first, making sure to leave all
fasteners loose, including the spreader arms (Parts #4 & #7).
2. Make sure the barrier gate is in the full closed position.
3. With someone’s assistance, lift the arm up to a height even with
the barrier gate flange. The far end should either be supported by
something of equal height as the flange, or be held by someone
throughout the next steps.
4. Assemble the wood arms (#10) between the attachment channels
(#8) and the flange and bolt together. Tighten these bolts (#9) firmly.
5. Tighten all bolts (#3) where the three pieces of wood arm come
together.
6. Tighten up the nuts (#6) on the spreader arms (#4 & #7) until the
plates (#5) are tight against the wood.
7. The arm should have a curved, wishbone appearance once finished.

Operator Preparation
Gear Reducer Vent Plug
In order to keep gear oil from spilling out during shipping,
gear reducers used in the SG and SG-D barrier gate
operators have a sealed vent plug installed at the factory.
Leaving the vent plug installed, remove the vent plug’s
breather pin to allow the gear box to vent (see Figure 5).
The breather pin can be discarded.
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, see Figure 6 and
follow the directions below.
1. For more downward travel, loosen the wingnut on the LSC-1 (down)
limit cam and rotate the cam slightly in the “B” direction.
2. For less downward travel, loosen the wingnut on the LSC-1 (down)
limit cam and rotate the cam slightly in the “A” direction.
3. For more upward travel, loosen the wingnut on the LSO-1 (up) limit
cam and rotate the cam slightly in the “A” direction.
4. For less upward travel, loosen the wingnut on the LSO-1 (up) limit
cam and rotate the cam slightly in the “B” direction.
✓NOTE: If the barrier gate operator has been custom
configured by the factory for reverse arm operation
(where the closed barrier arm sticks out from the service
door side of the operator) the limit switches shown in
Figure 6 will be reversed. The top limit switch will be the
open limit, the bottom limit switch will be the close limit.

operator’s top cover.
To access the Controller, from inside the operator, flip the
two cover release latches up to unlock the operator’s top
cover. Remove the cover to expose the Controller.
The Controller is protected by a plastic dust cover. To
remove the dust cover, loosen the cover’s wing-screw and
lift the cover off.
AC Power Connection
All Linear gate operators are supplied with a power
disconnect switch to turn on and off the power available to
the operator (see Figure 8). Following wiring specifications
on Page 2, incoming power should be brought into the
operator and connected to the labeled pigtails from the
disconnect box.
✓NOTE: FOR SOLAR POWERED UNITS ONLY: The
APeX Controller’s AC power disconnect switch does not
turn off the Apex DC power when connected to solar
panels. It will however, disconnect DC motor power.
Unplug the solar panel input on the front of the Apex
Controller prior to servicing the unit.
Proper thermal protection is supplied with the operator. The
motor contains a thermal overload protector to guard from
overheating the motor due to overload or high-frequency
operation. To reset the motor after an overload, press the
red button on the end of the motor after the motor has
cooled down.
Earth Ground
Install a ground rod and connect it to the operator’s frame
in every gate operator installation. A good earth ground is
necessary to allow the Controller’s built-in surge and lightning
protection circuitry to work effectively. The physical bolting
of the operator to the mounting pad is not sufficient for
a good earth ground.
✓NOTE: Do not splice the ground wire. Use a single piece of solid
copper 12 AWG wire between the ground rod and the operator.
1. Install an 8-foot long copper ground rod next to the operator mounting
pad within three feet of the operator.
2. Use a clamp to connect a solid copper 12 AWG ground wire to the
ground rod.
3. Route the ground wire to the operator.
4. Connect the ground wire to the operator’s frame.

Basic Controller Programming
Programming Overview
The Controller can be programmed with various options for the operator.
The programming fields are defined as “functions” that have “options”.
To make setup easier for the installer, the Controller’s programming is
divided into two groups: basic and advanced. The basic programming
group contains the functions commonly used in most swing gate
installations. The advanced programming group contains functions less
commonly used (i.e. dual gate stagger delay, maximum run timer, etc.).
Entering Programming Mode
Enter programming mode by pressing the UP and DOWN buttons
together for one second. While in programming mode the PROGRAM
indicator will light.
Exiting Programming Mode
Exit programming mode at any time by pressing the UP and DOWN
buttons together. The Controller will automatically exit programming
mode after three minutes of inactivity.
Programming Keystrokes
(Typical Programming Method)
While in programming mode, press the UP or DOWN buttons to scroll
through the programming functions. When the desired function is
displayed press the ENTER button to display the currently set option for
the function. When an option is displayed, the decimal points are lit.
To change the option, press and hold the ENTER button for 1 second. To
indicate that an option is ready to be changed, the display will flash.While
the display is flashing, press the UP or DOWN button to display the other
options available for that function.
When the desired option is displayed, press the ENTER button to store
it into memory. To select another function, press ENTER, UP, or DOWN.
Left or Right Hand Operation
The function is not used with barrier gates.
Dual Gate Enable
The factory default is for single gate operation. For dual gate operation,
wire the two gate controllers together through the COMM LINK terminals
(see Page 19) and enable dual gate operation with this programming
step.
Auto Close Timer
The factory default turns off the Auto Close Timer. The timer can be set
from 1 to 59 seconds and from 1 to 9 minutes. When the Auto Close
Timer is set, after opening, the gate will wait for the length of the Auto
Close Timer then close automatically.
Run Alarm and Pre-start Alarm
The function is not used with barrier gates.

Basic Controller Programming (Cont.)
Maximum Close Direction Current Setting
To detect obstacles or mechanical problems with the gate, the operator
can monitor its motor current. If the close current load exceeds the
programmed maximum load range number, the gate arm will stop,
reverse, and travel to the full open position. Another close request will
be required to start the operator again. If after restart, the overload or
a close obstacle happens again before the close limit is reached, the
operator will lockout and activate the alarm output. If the auto close timer
is set, when the close obstruction input is cleared, the gate arm will close
when the auto close timer expires.
The factory default setting of “OF” disables the close direction
current sensing for the operator. The maximum close direction
current setting can be adjusted using the following procedure:
To measure the motor load used during closing, while this function is
being displayed, push and hold the CLOSE button to close the gate.
During movement, the motor current will be displayed as a load number
from 0 to 99. This number is useful for troubleshooting but not used for
setting the motor current. At the end of travel, a different number will flash.
This number indicates the range above and below the average motor
current during the run. Using the + and - buttons, set the programmed
range number so that a minimal force will activate a reversal should an
obstruction occur, but high enough to keep the gate arm operating under
normal conditions without interruption.
Advanced Controller Programming
Entering Advanced Programming Mode
To access and program the Advanced Programming functions, for each
programming session, Advanced Programming must be enabled.
After exiting programming, the Advanced Programming functions
will be available on the programming display during the next
programming session unless the operator has run 50 or more
cycles. After that, Advanced Programming must be enabled again.
Maximum Run Time
The factory default for the Maximum Run Time (MRT) is 10 seconds.
When the operator starts, a timer will begin counting. If a open or close
limit is not reached or an obstacle or reversing input is not received before
the timer expires, the operator will stop, the unit locks out and the alarm
sounds. The timer can be set for 10 to 99 seconds, but should be left at
10 seconds in most applications. Setting it too close to the actual run time
may cause the time to expire with changing ambient temperature, gate
conditions, etc…
If AC is present and an open or close limit is not reached or an obstacle
or reversing input is not received before this timer exceeds MRT, the
operator will stop, the unit locks out and the alarm sounds.
In the case that AC is not present and MRT expires, it will be ignored as
long as the actual run time is under 10 seconds. When the gate reached
full open or full close position, MRT will be interpreted as fail safe/secure.
EN05 will occur. If FS as set to fail safe, the gate will open. If FS is set to
fail secure, the gate will close. However, if the actual run time is higher
than 10 seconds, it will be interpreted as a physical mechanical problem,
EN01 will occur and the gate will stop immediately.

Advanced Controller Programming (Cont.)
Single Button Input Setup
This function is used for selecting the operation for single button controls
and radio receivers.
The factory default sets the SINGLE input terminal so successive inputs
will cycle the operator in OPEN-STOP-CLOSE-STOP order.
Alternately, the SINGLE input can be set to cause the gate to OPEN
unless the gate is fully open. If the gate is closing, the input will cause
the gate to reverse. If the gate is fully open, the input will cause the gate
to CLOSE.
Stagger Mode
This function is not used in dual barrier gate installations.
✓NOTE:This function will only be displayed if dual
gate operation is selected.
Stagger Delay Time
This function is not used in dual barrier gate installations.
✓NOTE:This function will only be displayed if dual
gate operation is selected.
Auxiliary Relay Mode
The Auxiliary Relay has normally open and normally closed contacts.
The factory setting disables the Auxiliary Relay. The relay can be set for:
• Maglock: To deactivate a magnetic or solenoid gate lock, the relay
will energize during any pending or actual gate motion (open only).
• M4: To deactivate a magnetic or solenoid gate lock, the relay will
energize during any pending or actual gate motion (open only).
3 seconds after the gate starts to move, the relay will de-energize.
This option is used for higher current solenoid locks.
• Ticket Dispenser: The relay will energize while the gate is moving
in the open direction and at the full open limit, or in an entrapment
condition.
• Strobe: To activate a warning strobe light, the relay will energize
during any pending or actual gate motion (either open or close).
• Alarm: The relay will energize if the gate is manually forced open
from the full closed position.
Reverse Delay Time
The factory default sets the Reverse Delay to 0 seconds. The operator
will wait the length of the delay before reversing direction. This feature
will not change the reversal time when the operator is responding to an
entrapment condition from an obstruction input or inherent entrapment
protection sensor. The Reverse Delay can be set from 0 to 9 seconds.
Heaver gates require a longer delay to allow time for the gate to stop.
The Reverse Delay is active when the gate first stops on either limit or in
between limits.

Advanced Controller Programming (Cont.)
Low Power Mode
This function is only used with DC barrier gate Model SG-D. The factory
default disables the Low Power Mode. When Low Power Mode is enabled,
and AC power fails, the controller will assume Low Power Mode after 60
seconds of gate inactivity. Low power mode turns off all accessory power
and indicators. Only inputs from the radio receiver, reverse loop, open loop
(optional by programming), fire department input, or restoring AC power
will wake the Controller from Low Power Mode. Programming Mode can
still be accessed while the Controller is awake in Low Power Mode.
✓NOTE:This function will only be displayed in Model SG-D operators.
Power Failure Mode
This function is only used with DC barrier gate Model SG-D. The
factory default is set for Fail Safe, alternately the Controller can be set for
Fail Secure, Open Immediate, or Close Immediate.
• Fail Safe: If the AC power fails and the battery voltage drops below
approximately 22 Volts, 5 seconds later the operator will cycle open
if not already open. When AC power is restored, or the battery gets
charged by solar panels, the operator will resume normal operation
and auto-close if programmed to do so.
• Fail Secure: If the AC power fails and the battery voltage drops
below approximately 22 Volts, 5 seconds later the operator will
cycle closed if not already closed. When AC power is restored, or
the battery gets charged by solar panels, the operator will resume
normal operation.
✓NOTE:Fail Safe and Fail Secure are disabled if Stagger Mode is enabled.
• Open Immediate: If the AC power fails, the operator will cycle
open if not already open and cease operation. When AC power is
restored, the operator will resume normal operation and auto-close
if programmed to do so.
• Close Immediate: If the AC power fails, the operator will cycle
closed if not already closed and cease operation. When AC power is
restored, the operator will resume normal operation.
✓NOTE:This function will only be displayed in Model SG-D operators.
Soft Start/Stop Duration
This function is only used with DC barrier gate Model SG-D. This
function causes the operator to start and stop the DC motor slowly
reducing gate wear and tear (at the full open or closed positions only).
The factory default sets the Soft Start/Stop Duration to 3 seconds. The
Soft Start/Stop Duration can be set from 1 to 10 seconds.
✓NOTE:Changing the Soft Start/Stop Duration will reset the open and
close current setting value to zero. It will be necessary to reprogram
maximum open and close current settings.
✓NOTE:This function will only be displayed in Model SG-D operators
set for DC motor operation with soft start motor selection.
Reset Cycle Count
The Controller counts of the number of times the operator has been cycled
full open and close. The cycle count can be displayed. The display will
scroll the cycle count number, flashing two digits at a time from left to right.
To reset the Cycle Count, press and hold the ENTER button for 2 seconds
while the Cycle Count is displayed.
If the Maintenance Alert has been triggered, resetting the Cycle Count
will also reset the Maintenance Alert indicator.

Advanced Controller Programming (Cont.)
Maintenance Alert Trigger
The Controller has a MAINT ALERT indicator that can be programmed
to light when the number of activations exceeds a set number of cycles.
The factory default sets the Maintenance Alert Trigger to 10,000 cycles.
The Maintenance Alert Trigger can be programmed for 5, 10, 15, or
25 thousand cycles.
The Maintenance Cycle Count can be reset independently from the
operator’s absolute Cycle Count.
Open/Reset Input
✓NOTE:For use in single gate installations only.
The Controller can be programmed to partially or fully open the gate with
an OPEN/RESET input, or to count the number of open commands and
leave the gate open until an equal number of SHADOW/RESET loop
triggers occur.
The OPEN/RESET terminals can connect to a loop detector or normally
open switch (see accessory wiring in Figure 10 on Page 10). The
SHADOW/RESET loop uses a plug-in loop detector.
The factory default is setting is Off (OF).
• OF Open Mode Off: The OPEN/RESET input acts as a standard
RESET loop and holds the gate arm open as long as a vehicle is on
the loop. If the gate arm is opening or fully open when the vehicle
exits the loop, the gate arm will close.
• CT Open Counter Mode: The Controller can count and remember
the number of open commands received, and will count the same
number of SHADOW/RESET loop triggers before the gate will close.
✓NOTE:Set the Auto Close Timer to OFF when using the CT option.
• SU Open Supervised Mode: The OPEN/RESET input opens the
gate arm fully on the initial command. Once open, the arm will
close on the removal of the command.
Anti-tailgate
The Controller can be programmed to have the barrier gate arm prevent
“tailgating” when a second vehicle attempts to drive through closely
following a prior vehicle that has been granted access.
The factory default disables this feature. If the SHADOW/RESET loop is
activated while the gate arm is closing, the gate arm will stop. When anti-
tailgate is enabled, the SHADOW/RESET loop will be ignored once the
arm begins traveling downward.
Radio Enable
The Controller contains a built-in MegaCode®radio receiver to allow
activation from up to 40 access control transmitters and two Model MGT
(gate edge) transmitters. The factory default enables the internal radio
receiver. Alternately, the internal receiver can be disabled.
Antenna Installation
A local whip antenna is included for use with the operator as a remote
antenna. If using a remote antenna, connect coax cable from the antenna
to the ANTENNA connector.
