Pre-installation Information

Before You Begin...

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.

If you have any questions about the requirements for proper
installation of this gate operator contact technical support at
800-421-1587.

Always Check the Gate’s Action

It’s very important before installing the gate operator to
make sure the gate slides is free and level throughout
the entire opening distance. If the gate does not seem to
operate properly, it may affect the operator performance
or greatly shorten the life of the unit. The gate should
also be designed so that airfl ow is ample to prevent
wind resistance and drag.

Gate Operator Classifi cations

All gate operators can be divided into one of four different
classifi cations, depending on their design and usage. Install
this gate operator only when the operator is appropriate for
the construction and usage class as defi ned below:

• Class I Residential Vehicular Gate Operator

A vehicular gate operator intended for use in a home or for one to
four single family dwellings with a common 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 multi-family 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.

Regulatory Warnings

Read the following before beginning to install this slide gate
operator:

IMPORTANT INSTALLATION SAFETY INSTRUCTIONS

WARNING

TO REDUCE THE RISK OF SEVERE INJURY OR DEATH
TO PERSONS, REVIEW THESE INSTALLATION SAFETY

STEPS BEFORE PROCEEDING

1. READ AND FOLLOW ALL INSTALLATION INSTRUCTIONS.

2. Read the yellow “Safety Instructions” brochure enclosed with the

packet of information. If any pages are missing or are unreadable,

or you do not have the safety instructions, please call Linear at

1-800-421-1587 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. Install the enclosed warning signs on both sides of the gate. A

minimum of two (2) WARNING SIGNS shall be installed, one on each

side of the gate where easily visible.

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

gate.

7. Never connect a button station within reach of the gate or on the

side of the gate operator.

8. 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!

9. You must install all required safety equipment.

10. UL325 Compliance requires the use of contact edges or photoelectric

controls on all automatic or remotely-controlled gate operators.

11. 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 into contact with the vehicular gate during the entire path

of travel of the vehicular gate.

Wiring Specifi cations

Refer to the following steps for details on power and
accessory wiring for the operator.

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.

USE COPPER WIRE ONLY!

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 24 for details of this connection. Note: The shield

wire should be connected in both the operators.

Mounting Pad Installation

The gate operator mounts bolted to posts secured in
concrete footings. The posts support the operator and
prevent it from moving during operation. For optional pad
mounting instructions, see Linear drawing #2700-360.

Gate Preparation

Before installing, make sure the gate rolls or slides freely,
and that all exposed rollers are properly covered. The gate
must be covered with fabric with openings no larger than
2-1/4” in size, to a minimum height of 72” above ground
level. On picket-style gates, if pickets are spaced less than
2-1/4” apart, mesh is optional.

Mounting Specifi cations

Use two 3 - 3-1/2” OD galvanized posts and secure with
concrete footings as shown, length to be determined by
local codes, frost line depth and soil conditions.

Attach the operator with the U-bolts, side plates and
hardware provided. Four 3/16” side plates go on the outside
top and bottom, two 1/2” side plates go on the inside top,
and two 3/16” side plates go on the inside bottom (see the
illustration at right).

To assemble the drive chain and gate brackets, refer to
Page 4. Make sure that the chain sag does not exceed
recommended sizes and that the chain does not come into
contact with the moving parts of the gate or ground.

WARNING

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 into contact with the vehicular gate during the
entire path of travel of the vehicular gate.

WARNING

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.

Operator Preparation

Vent Plug Installation

In order to keep gear oil from spilling out during shipping,
gear reducers used in gate operators have either a solid
plug, or a sealed vent plug, installed at the factory.

For operators with a solid plug, replace the solid plug with
the vent plug provided (see Figure 3).

With the vent plug installed, remove the vent plug’s breather
pin to allow the gear box to vent (see Figure 3).

Gate Bracket and Chain Assembly

✓ NOTE: The item numbers shown in these illustrations

are for reference only. For the actual part numbers, refer
to the parts lists in the rear of this manual.

Assemble a gate bracket (1) to the front edge of the gate,
using two U-bolts (2), and mounting hardware (3). Before
tightening down completely, be sure the bracket is parallel
to the gate. Tighten the U-bolt hardware the rest of the way,
then screw the square head bolts (4) into the threaded
holes in the gate plate until they bottom out against the gate.
These will help keep the bracket from twisting on the pipe.
Additional mounting holes have been provided in the gate
bracket for installer convenience.

Slide a threaded chain pin (5) through the bracket as shown,
with spring (6), fl at washer (10), and two hex nuts (7). Attach
one end of the drive chain (8) to the chain pin using master
link (9) and begin unrolling the chain toward the operator.

Remove the rain cover from the back of the slide gate
operator. Carefully thread the drive chain under the fi rst
idler, over the drive sprocket, and then under the last idler.
Make sure you feed most of the chain through the idlers and
sprocket before attaching the chain to the back end of the
gate.

Assemble the other gate bracket on the rear edge of the
gate, using the same process as the front gate bracket.
Once this is done, take the other chain pin, spring and jam
nuts and assemble with the end of drive chain and the other
master link.

At this point you should be able to adjust the chain tension
by tightening the jam nuts on each end. Approximately
1/4” to 3/8” of slack per foot of drive chain is acceptable.
Make sure the chain does not drag on the ground, across
the gate rollers or the idler frame of the operator.

Chain Supports

When necessary, due to the length of the gate and chain,
chain supports should be added to the gate at equally
spaced distances to allow the chain to sag as little as
possible. A bolt located one inch below the chain line should
be adequate.

Operator Setup

Controller Access

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 (see Figure 7).

Manual Disconnect

The manual disconnect shifter lever and the locking lever is
illustrated in Figure 8. They can be found at the center and
to the left inside the operator cabinet. (The handle of each
has been fi nished in easy to spot red fi rm-grip coating.)

To disconnect the unit for manual operation, grasp the
handle of the spring-loaded shifter lever and pull it directly
toward you until the spring-loaded locking lever snaps into
place behind it. This action disengages the pinned shifter
block from the drive mechanism and holds the block in the
disengaged position.

To re-engage the operator, move the locking lever to the
right, releasing the spring-loaded shifter lever to snap back
into the engaged position.

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

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. Following wiring specifi cations on Page 2,
incoming power should be brought into the operator and
connected to the labeled pigtails from the disconnect box.
A wiring connections print can also be found on the label
inside the cover of the operator.

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. This overload protector will reset automatically
after the motor cools 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 posts is not suffi cient
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.

Operator Setup (cont.)

Open and Close Limit Adjustment

The limit nuts are not preset at the factory and must be adjusted
for the gate in each installation. The limit switches are activated
by two threaded nylon rotary limit nuts which are attached to
a threaded limit shaft driven by a chain and sprockets from
the main drive shaft. REMOVE THE CARDBOARD FILLER

BEFORE ADJUSTING THE LIMIT NUTS.

The Controller is factory setup for right-hand installations.
The OPEN limit switches are the ones closer to the front
of the operator. In left-hand installations, the CLOSE limit
switches are the ones closer to the front of the operator (see
Figures 10 & 11).

CAUTION

If the operator is installed in a left-hand installation. Set the
Controller to left-hand operation BEFORE running the operator
for the fi ne setting of the limit cams. Failure to do so will result
in over-shooting the limit switches, and may cause damage to
the operator and/or gate. Refer to programming on Page 12.

Limit Nuts Rough Adjustment

Before running the operator, set the limit nuts as follows:

1. With the gate connected to the gate operator in a mid-travel position,
turn the power disconnect switch OFF.

2. To adjust the limit nuts, press down on the detent plate and rotate the
limit nut along the threaded shaft (see Figure 12).

3. Adjust the OPEN limit nut until it is about 1/2” from activating the
LSO-2 OPEN limit switch.

4. Adjust the CLOSE limit nut until it is about 1/2” from activating the
LSC-2 CLOSE limit switch.

Limit Nuts Fine Adjustment

After fi nishing the rough limit nut adjustments, run the
operator to set the fi ne limit adjustment.

1. Turn the power disconnect switch ON.

2. Stand clear of any moving parts and press the OPEN button.

3. After the gate opens, press the CLOSE button.

4. Observe the gate in both directions as it runs through each complete
cycle. Adjust the open or close limit nuts again if necessary. Fine
levels of adjustment can be made by adjusting a few teeth on the
nut at a time. If the gate stops during travel, you may need to adjust
the Open or Close Current Setting or the Maximum Run Timer (see
Pages 13-14).

Setting Speeds using LSO-2 & LSC-2

Limit switches LSO-2 and LSC-2 control when the operator
accelerates to maximum speed and decelerates to
minimum speed. It is recommended that LSO-2 and LSC-2
are adjusted fi rst so the gate slows to near stop before
hitting LSO-1 or LSC-1 as these will apply the brake upon
activation.

Adjust LSO-2 and LSC-2 by slightly loosening the two
screws which hold them in place and sliding toward or away
from the center of the limit box. Care must be taken not to
adjust too close to the center as the limit nut may travel past
the switch and start accelerating at the end of the cycle.

P1255 Revision X5 7-7-2011

Operator Setup (Cont.)

Torque Limiter Adjustment

Before adjusting the torque limiter, make sure the gate
is in good working condition. With the gate disconnected
from the gate arm, one person should be able to move the
gate by hand. Be certain the gate moves freely and without
binding throughout its travel.

Torque limiters are set light at the factory. They must be
adjusted during installation, preferably after limit cams have
been manually set. With the gate arm and gate attached,
adjust the torque limiter tight enough to keep it from slipping
during normal operation. The inherent entrapment protection
(current sensing) feature must activate prior to any slipping
of the torque limiter.

✓ NOTE: The open and close current sensing may need to be

adjusted before performing the following two steps. See Page 13.

To adjust the torque limiter in a Model VS-GSLG:

1. Loosen the set screw on the adjustment nut.

2. Cycle the gate open and closed while observing the torque limiter
action. TURN THE OPERATOR POWER DISCONNECT SWITCH
OFF BEFORE MAKING ANY ADJUSTMENTS.

To increase the torque, turn the adjustment nut clockwise one fl at, or
1/6 turn, at a time until desired output is obtained.

To reduce the torque, turn the adjustment nut counterclockwise one
fl at, or 1/6 turn, at a time until desired output is obtained.

3. When fi nished, tighten the set screw to lock the adjustment nut in
place.

Basic Controller Programming

Programming Overview

The Controller can be programmed with various options for the operator.
The programming fi elds are defi ned 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 slide 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 fl ash. While
the display is fl ashing, 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 factory default is for right hand operation (operator on right side of
the driveway when viewed from the inside of the gate). For left hand
installations, program the Controller for left hand operation.

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 24) and enable dual gate operation with this programming
step.

✓ NOTE: The Mid-travel Stop feature is disabled when dual gate

operation is enabled for paired units.

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.

Basic Controller Programming (Cont.)

Run Alarm and Pre-start Alarm

The factory default is Run Alarm on and a 3-second Pre-start Alarm. The
operator’s beeper will sound 3 seconds before the operator starts. The
options are:

• Run Alarm Off and Pre-start Alarm Off

• Run Alarm On and Pre-start Alarm Off

• Run Alarm On and Pre-start Alarm On for 1-9 Seconds

Maximum Open Direction Current Setting

To detect obstacles or mechanical problems with the gate, the operator
monitors its motor current. If the open current load exceeds the
programmed maximum load range number, the operator will stop, reverse
a short distance, then stop again. The Auto Close Timer will be disabled,
and another open request will be required to start the operator again. If
after restart, the overload or an open obstacle happens again before the
open limit is reached, the operator will lockout and sound the alarm.

To measure the motor load used during opening, while this function is
being displayed, push and hold the OPEN button to fully open 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 for setting
the motor current. At the end of travel, a different number will fl ash. 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 (50-75 lbs.) will activate a reversal should
an obstruction occur, but high enough to keep the gate moving under
normal conditions without interruption.

To detect obstacles or mechanical problems with the gate, the
operator monitors its motor current. If the close current load exceeds
the programmed maximum load range number, the operator will stop,
reverse, and travel to the full open position. Should a open obstruction
input or an open direction inherent entrapment condition occur prior to
the gate reaching the open limit, the operator will lockout and sound the
continuous tone alarm. 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
sound the alarm. If the auto close timer is set, when the close obstruction
input is cleared, the gate will close when the auto close timer expires.

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 fl ash.
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 (50-75 lbs.) will activate a reversal
should an obstruction occur, but high enough to keep the gate moving
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 99 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 99 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.

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 fully open, the input will cause
the gate to CLOSE.

Stagger Mode

This function is used in dual gate installations only. The factory
default sets the Stagger Mode to OFF. In dual gate installations the
two operators communicate through the 3-wire COMM LINK interface.
When using the Stagger Mode, set one operator for delayed opening and
the other operator for delayed closing. The Stagger Time programming
function (see below) sets the length of the delay.

✓ NOTE: This function will only be displayed if dual gate operation is

selected.

Stagger Delay Time

This function is used in dual gate installations only. The factory
default sets the Stagger Time to 0 seconds (OFF). The Stagger Time
sets the delay for the Stagger Mode. The Stagger Delay Time can be set
from 1-99 seconds.

✓ NOTE: This function will only be displayed if dual gate operation is

selected.

Advanced Controller Programming (Cont.)

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 1 second. 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 1 to 9 seconds.
Heaver gates require a longer delay to allow time for the gate to stop.

Brake Delay Time

The factory default sets the Brake Delay to no delay (0 seconds). Heavy
gates may require delayed braking to allow the gate to slow down before
stopping it. The operator can be set to wait the length of the delay after
running before applying the brake. The Brake Delay can be set from
0 to 3 seconds.

Constant Pressure Mode

The factory default allows momentary pressure on a control station’s
OPEN or CLOSE button to cycle the operator. The controller can be set
to require constant pressure on the OPEN, CLOSE, or both buttons to
run the operator.

✓ NOTE: If a button is set for constant pressure, and it is released

before the operator reaches the open or close limit, the operator will
stop the gate at its current position.

Shadow Loop Open Prevention

If the shadow loop is triggered, it always prevents the gate from closing if
the Auto Close Timer activates or a CLOSE command is given while the
gate is at the full open position.

The controller can also be set to prevent the gate from opening if the
shadow loop is triggered while the gate is at the close limit position. This
prevents a swing gate from opening into a vehicle if it’s parked near the
gate on the inside.

Advanced Controller Programming (Cont.)

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, fl ashing 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.

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.

Mid-travel Stop Position

The Controller can be programmed so the gate will stop at a mid-travel
point instead of fully opening. This can be useful in installations where a
large gate, that takes a long time to open and close fully, only needs to
be opened partway to allow traffi c to pass.

The factory default sets the Controller for full open operation. Alternately,
the Controller can be programmed to open for 1 to 99 seconds then stop,
before reaching the open limit.

When a Mid-travel Stop Position time has been programmed, the gate
will still fully open if the Fire Department input is triggered, if the OPEN
button is held down beyond the Mid-travel Stop Position, or a close
obstruction or reverse loop input is triggered.

✓ NOTE: The Mid-travel Stop feature is disabled when dual gate

operation is enabled for paired units.

Anti-tailgate Enable

The factory default sets the Anti-tailgate Enable to OFF. With this setting,
during a gate cycle, after the shadow loop has been triggered by the
vehicle and then has cleared after the vehicle passes, the Auto Close
Timer or a CLOSE command is required to begin closing the gate.

If the Anti-tailgate Enable is set to ON, the gate will close immediately
as soon as the shadow loop has cleared. Any subsequent shadow loop
triggers while the gate is closing will stop the gate. When the shadow loop
clears, the gate will continue closing.

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

The Controller is supplied with a local whip antenna installed. If using a
remote antenna, remove the whip antenna and connect coax cable from
the antenna to the ANTENNA connector.

Dual Gate Installations

Optional In-Cabinet Heater

Two operators can be used in dual gate installations. The operators
communicate with each other through the 3-wire COMM LINK terminals.

When one operator activates, the COMM LINK connection signals
the other operator to activate. Each operator functions independently,
controlling its gate and monitoring its inputs and accessories.

A three-wire shielded conductor cable is required to connect two
operators together for dual operation. Use Belden 8760 Twisted Pair
Shielded Cable (or equivalent) only – P/N 2500-1982, per foot).

✓ NOTE: The shield wire should be connected COMM LINK terminal

“C” in both operators.

Three of the programming functions available are only used for dual gate
installations:

• Dual Gate Enable

Dual Gate Enable must be set for all dual gate installations.

• Stagger Mode

The Stagger Mode function determines if the operator has a delayed
open or a delayed close. In dual swing gate installations, typically one
operator is programmed for delayed open, and the other operator is
programmed for delayed close.

• Stagger Delay Time

The Stagger Time sets the length of the delay for the Stagger Mode.

See Pages 12 & 14 for details on these three dual gate programming
functions.

Set the following parameters in each gate operator individually in a single gate
mode before connecting the network cable and operating in dual gate mode.

1. Open and Close Limit settings

2. Open and Closed direction inherent
entrapment protection (OC & CC)

After these parameters have been set, and each operator has been
tested independently and is functioning correctly in single gate mode,
then set BOTH operators to dual gate (dg) in the Paired Mode setup step
under Basic Programming steps.

The operator can be ordered with an optional cold weather
package that includes an in-cabinet heater to keep the drive
train and electronics warm in cold environments.

In-cabinet heaters can also be ordered separately and
should be wired to the operator as shown in Figure 17.

Gate Operation

Open Button

Opens the gate. If the Controller is programmed to stop
opening the gate at mid-travel, a constant press of the OPEN
button will override the Mid-travel Stop and completely open
the gate. If the Auto Close Timer is set, it will be suspended
until the OPEN button is released.

Reverse Input

If the reverse input is triggered while the gate is closing, the
gate will reverse to the full open position. If the Auto Close
Timer is set, when the reverse input is cleared, the gate will
close when the Auto Close Timer expires.

Open Loop

Functions the same as the OPEN button.

Close Button

Closes the gate if the gate is open. Also closes the gate if
the gate is in the process of opening.

Stop Button

Stops the gate from opening or closing at any time.

Single Input

Opens the gate if it’s closed and closes the gate if it’s open
(open-close programming option). Activating the input while
the gate is moving will reverse the gate.

Can be programmed to stop the gate while the gate is
moving (open-stop-close programming option).

Fire Department Input

Fully opens the gate when the input is activated. Overrides
the Mid-travel Stop and Auto Close Timer (if either is
programmed for the gate). The gate will lockout in the open
position without sounding the alarm. Press the STOP button
to release the lockout.

Open Input

Functions the same as the OPEN button.

Open Obstruction

While the gate is opening, any open obstruction signal will
cause the gate to stop, reverse a short distance, and then
stop again. The Auto Close Timer will be disabled, and a
renewed input will be required to start the gate again. Should
the gate be restarted and the obstacle signal occur again
prior to reaching a limit, the gate will stop again, lockout,
and sound the emergency alarm.

Close Obstruction

While the gate is closing, any close obstruction signal
will cause the gate to stop, reverse, and travel to the full
open position. Should a open obstruction input or an open
direction inherent entrapment condition occur prior to the
gate reaching the open limit, the operator will lockout and
sound the continuous tone alarm. 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 sound
the alarm. If the auto close timer is set, when the close
obstruction input is cleared, the gate will close when the
auto close timer expires.

Reverse Loop

Functions the same as the reverse input.

Shadow/Reset Loop

Holds the gate fully open or fully closed while triggered.
If open, the gate closes immediately when cleared if
Anti-tailgate is enabled.

Operation Indications

During normal operation, the Controller’s displays will
indicate current operating conditions and status.

Power-up Display

When the Controller powers up, dashes will show on the
display, then the fi rmware version number, then the gate
type (SL for slide and swing gates).

Exiting programming restarts the Controller. The power-up
display will show upon the restart.

Idle Condition

While the Controller is idling, waiting for a command, the
display will show circulating dashes.

Last Gate Position/Condition

When the gate moves or stops, the display will show the
status for up to one minute.

• Stop is displayed as St

• Full Close is displayed as FC

• Full Open is displayed as FO

• Entrapment is displayed as En

Pre-start Delay

During the pre-start delay, the display will countdown the
number of seconds remaining before the operator starts.

Reverse Delay

If the gate travel direction is reversed from a user activation
or reversing device, and a reverse delay is set, the display
will count down the delay time in seconds before the
operator restarts.

Run Timer

While the gate is opening or closing, the number of seconds
running time is displayed.

Error Indications

During abnormal operation, the Controller’s displays and
beeper will indicate the error condition that has occurred.

Entrapment

If an entrapment condition occurs detected by two repeated
open or close obstruction triggers, the Controller will lock
the operator out. The beeper will sound constantly and the
gate will not operate. To reset the Controller press the STOP
button or press the RESET button on the operator’s cover.

WARNING

The Stop and/or Reset button must be located in the line-of­sight of the gate. Activation of the reset control shall not
cause the operator to start.

COMM LINK Connection Failure

In dual gate installations, if there is a connection failure
between the two operators, the COMM LINK indicator will
blink once a second. During this condition the gate will not
operate, except if triggered by the FIRE DEPT input, which
functions normally.

MGT Obstacle Transmitter Trouble

If any MGT transmitters are used with the operator, their
supervision feature will alert the Controller if there is any
trouble with the transmitter. MGT transmitters send hourly
status reports and will send low battery reports when the
transmitter has a low battery. The MGT transmitters also
have a tamper detection switch that will trigger when their
case is opened.

When the Controller detects a low transmitter battery, a
tamper signal, or missing transmitter status reports, the
gate will still operate normally, but the beeper will change
as follows:

• The Pre-start Alarm will beep twice as fast.

• The Run Alarm will beep twice as fast and continue for fi ve minutes
after the gate stops.

• The sounder will “chirp” every fi ve seconds when the gate is idle.

Correct the trouble (close case, replace battery, or replace
transmitter) to clear the obstacle transmitter trouble
indications.

Troubleshooting

Contacting Technical Support

For technical questions regarding Linear gate operators, contact the
Technical Services Department at:

1-800-421-1587

Operator fails to start

A. If the operator has been running a large number

of cycles, the motor may have become too hot and
tripped its thermal overload breaker. Allow the motor to
cool down and the thermal overload breaker will reset
automatically.

B. Make sure you have power at the master distribution

panel and that the power has not been turned off.

Motor operates, but gate does not move

A. In operators with torque limiters and friction pad clutches,

check for signs of slipping. You can mark the sprocket
and clutch with a yellow or white grease pen and watch
for the lines to move apart if slipping is taking place.
Adjust the torque limiter tighter if this is the problem.

B. Check for broken chain or worn belts.

C. 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.

B. Check the drive chain for obstructions (if the operator

has one).

C. If the operator has an internal brake mechanism, make

sure it is releasing.

from 5:00 AM to 4:30 PM Pacifi c time

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

A. The Controller 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 beeper will sound.

C. An obstruction signal from an accessory wired to the

obstruction input may have triggered falsely. Check the
control board for lit indicators for any of the following
inputs: safety, shadow/reset, 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 9 for details on the control board indicators.

Gate staying open with automatic system

A. If there are vehicle detectors used with the operator, one

of the loops or loop detectors may be sending a false
signal or needs to be reset. Observe the indicators on
the loop detector. Unplug the detector 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.

Limit switch getting out of time

A. Check for proper tension on all limit chains to be sure

there is no jumping taking place. Mark one tooth and its
corresponding link and run the gate. If the marks have
moved, the chain is skipping.

B. Check the setscrews in limit sprockets for tightness. In

rotary limit boxes, check the rotary limit nut for sloppiness
or stripped threads. Replace if necessary.

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.

3. State whether to ship by freight, truck, parcel post, UPS or air express.

4. State whether transportation charges are to be prepaid or collect.

5. Specify name and address of person or company to whom parts are to be shipped.

6. Specify name and address of person or company to whom invoice is to be sent.

Preventative Maintenance

WARNING

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 a 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 grease 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 — The main drive chain and

sprockets should be inspected for wear, cleaned, and
wiped down with a lightly oiled rag every six months.

6-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.

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.

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
photoeyes 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.

For all 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.
