Pre-installation Information

Safety Information and Warnings

Before You Begin...

THE FOLLOWING FORMATS ARE USED FOR SAFETY NOTES
IN THESE INSTRUCTIONS.

Before unpacking, inspect the carton for exterior damage. If
you find 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.

CAUTION
This type of warning note is used to
indicate the possibility of damage to the
gate or gate operator.

WARNING

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.

This type of warning note is used to
indicate possible mechanical hazards that
may cause serious injuries or death.

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

WARNING
This type of warning note is used to indicate
possible electrical shock hazards that may
cause serious injuries or death.

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 airflow is ample to prevent
wind resistance and drag.

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

Gate Operator Classifications
All gate operators can be divided into one of four different
classifications, depending on their design and usage. Install
this gate operator only when the operator is appropriate for
the construction and usage class as defined 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 five 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.

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.

P1255 Revision X5 7-7-2011

Wiring Specifications
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

WARNING

Gate Preparation

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.

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.

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.

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.

WARNING

Mounting Specifications
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.

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).

✓ 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.

Figure 3. Vent Plug Installation

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), flat 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 first
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.

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 finished in easy to spot red firm-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.

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).

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 first 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 flat, or
1/6 turn, at a time until desired output is obtained.

Programming Overview
PROGRAM
INDICATOR

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 slide gate
installations. The advanced programming group contains functions less
commonly used (i.e. dual gate stagger delay, maximum run timer, etc.).

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 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 (50-75 lbs.) will activate a reversal should
an obstruction occur, but high enough to keep the gate moving under
normal conditions without interruption.

Maximum Close Direction Current Setting
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.

programming session, Advanced Programming must be enabled.

OPTIONS

ADVANCED PROGRAMMING OPTIONS
WILL BE DISPLAYED

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.

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.

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.

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).

In-cabinet heaters can also be ordered separately and
should be wired to the operator as shown in Figure 17.
Contact Technical Services for heater wiring information for
a specific voltage and phase of operator.
SINGLE PHASE 115V, 208V, & 230V MODELS
(All heaters have built-in switch and thermostat)

✓ 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:

POWER BOX

• 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.

208/230 VOLT HEATER (P/N 2510-273)

CONNECT TO LEADS LABELED
"ACCESSORY POWER CONNECTION"

THREE PHASE 208V & 230V MODELS

• 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.

208/230 VOLT HEATER (P/N 2510-273)

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.

Reverse Input

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.

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

Reverse Loop

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

Functions the same as the reverse input.

Stop Button

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

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.

Shadow/Reset Loop

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

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

Power-up Display

Fire Department Input

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

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.

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

Idle Condition

Functions the same as the OPEN button.

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

Open Obstruction

Last Gate Position/Condition

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.

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

Close Obstruction

Pre-start Delay

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.

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

Error Indications

CONTROLLER ERROR CAUSES AND 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 five minutes
after the gate stops.
• The sounder will “chirp” every five seconds when the gate is idle.
Correct the trouble (close case, replace battery, or replace
transmitter) to clear the obstacle transmitter trouble
indications.

Maximum Run Time Exceeded
If the Maximum Run Time is exceeded, the Controller stops
the operator the same as if a double obstacle has occurred
in an entrapment condition. The entrapment alarm sounds
constantly, and is cleared by pressing the STOP button or the
RESET button on the cover. After the STOP or RESET button
is pressed, because the Maximum Run Time has been
exceeded, the sounder will beep twice every five seconds.
The next operation of the gate will clear the indication.

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

Troubleshooting
Contacting Technical Support
For technical questions regarding Linear gate operators, contact the
Technical Services Department at:
1-800-421-1587 from 5:00 AM to 4:30 PM Pacific time

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.

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.

6-Month Preventative Maintenance

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

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
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.

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 fix as
required. Failure to keep the gate in
good working condition will have
adverse effects on the operator.
