GATE OPERATOR

CLASSIFICATIONS

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

Class I: Residential

A vehicle gate operator (or system) intended for use in a
home of one to four single-family dwellings, or a garage or
parking area associated therewith.

Class II: Commercial or General Public Access

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

Class III: Industrial or Limited Access

A vehicular gate operator (or system) intended for use in
an industrial location or building such as a factory or load­ing dock area or other locations not intended to service
the general public.

Class IV: Restricted Access

A vehicular gate operator (or system) 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.

SAFETY INFORMATION

AND WARNINGS

Read the following before beginning to install LINEAR slide
gate operators:

1. Read the yellow “Safety Instructions” brochure enclosed
with the packet of information. If you do not have one,
please call LINEAR at 1-800-333-1717 to request one.
Read and follow all instructions.

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

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

4. A minimum of two (2) WARNING SIGNS shall be in­stalled, one on each side of the gate where easily vis­ible.

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

6. You must install all required safety equipment.

PRE-INSTALLATION INFORMATION

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

IMPORTANT!!

Before installing the gate operator, make sure the gate’s slide
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 be designed so that airfl ow through the fabric
is ample to prevent wind resistance and drag.

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

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

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

HSLG OPERATOR INSTALLATION GUIDE

WIRING SPECIFICATIONS

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

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

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

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

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

USE COPPER WIRE ONLY!

6. Connect power in accordance with local codes. The green ground
wire must be properly connected.

7. Wire insulation must be suitable to the application.

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

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

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

Note: The SHIELD wire should be connected in both the master
and slave operators.

HSLG OPERATOR INSTALLATION GUIDE

POST MOUNTING INSTRUCTIONS FOR MODEL HSLG

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 48 inches from ground
level. On picket-style gates, if pickets are spaced less than
2 1/4” apart, mesh is optional.

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. Secure the
operator to the posts using the 4” U-bolts, side plates,
and hardware. There are a total of eight side plates. There
are six 3/16” side plates which should be mounted on the
outside top and bottom of the cabinet, two 3/16” side plates which
go on the top inside and two 1/2” side plates which should be
mounted on the inside top of the cabinet as shown in the illustra­tion at the right.

To assemble the drive chain and gate brackets, refer to page 6.
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.

For optional pad mounting instructions, see LINEAR drawing
#2700-360.

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 pedes-

trian usage. Locate the gate such that persons will
not come in contact with the vehicular gate during

the entire path of travel of the vehicular gate.

GATE BRACKET AND CHAIN ASSEMBLY INSTRUCTIONS

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.

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.

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 it 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 sprockets for
attaching to the back end of the gate.

Assemble the other gate bracket on the rear edge of the
gate, using the same process as you did with 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.

Additional mounting holes have been provided in the gate
bracket for installer convenience.

HSLG OPERATOR INSTALLATION GUIDE

TORQUE LIMITER ADJUSTMENTS

Before adjusting the torque limiter, make sure the gate is in good working condition. 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 and must be adjusted
during installation. Adjust the torque limiter tight enough to keep it from slipping during normal
operation.

To adjust the torque limiter in model HSLG:

1. Loosen the jam nut.

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

To reduce the output, turn the adjustment nut counterclockwise one fl at, or 1/6 turn, at a

time until desired output is obtained.

3. Tighten the jam nut against the adjustment nut when fi nished.

HSLG OPERATOR INSTALLATION GUIDE

ELECTRICAL CONNECTION AND ADJUSTMENTS

Power supply must be of correct voltage and phase.
Always disconnect power from operator before servicing.
Keep clear of gate during operation.

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

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

LIMIT NUT ADJUSTMENTS

The limit nuts are not preset at the factory and must be adjusted for the length of the gate the operator is installed on. The
limit switches are activated by two threaded nylon rotary limit nuts which are attached to a threaded shaft and driven by chain
and sprockets from the main drive shaft. Remove the cardboard fi ller before attempting to adjust the limit nuts.

With the gate connected to the gate operator in a mid-travel position, and the power disconnect switch turned OFF, discon­nect the operator by using the manual disconnect lever. Instructions for the manual disconnect can be found in the individual
operator owner’s guides. Once the operator has been disconnected, manually move the gate by hand to within a foot of its
fully open position (the foot of distance is necessary to allow for coasting of the operator after the limit switch is tripped).

Once the gate is in this position, adjust the open limit nut until it activates the limit switch for open, LSO-1. Press down on
the detent plate and rotate the nut along the threaded shaft. Refer to the illustration below for additional details.

Once the open limit nut is set, repeat the above process for the close direction nut and the LSC-1 limit switch.

After fi nishing the initial limit nut adjustments, reposition the gate to approximately its center of travel. Re-engage the operator
and turn the power disconnect ON. Stand clear of any moving parts and press the OPEN button on the three-button station.
If the gate begins to close instead of open, press the STOP button immediately. Find the dip switch block on the main control
board and switch the hand of operation (dip switch #4, see page 9) and try to open the gate again. Observe the gate as it
runs through a complete cycle in both directions, and adjust your limits again if necessary. Fine levels of adjustment can also
be achieved by adjusting a few teeth on the nut at a time. If the gate stops in mid travel, the open or close current sensor
adjustment or the maximum run timer may need adjustment (see page 11).

DIAGNOSTIC

L.E.D.s

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

provided no open, reversing or obstruction signals are present from the fully-open position. This timer is adjustable from 0
to 124 seconds. This feature is turned on or off using dip switch #1.

Maximum Run Timer Adjustment: This 270-degree adjustable potentiometer will signal the operator to stop running once
it counts down, unless a limit switch is reached or an input is received fi rst. Each time the motor starts, this timer will begin
counting. This timer is adjustable from 15 to 100 seconds. If the timer expires, the unit locks out and the emergency alarm
sounds.

Open Direction Current Sense Adjustment: This multi turn potentiometer is used to calibrate the built-in current sensing
feature for detection of obstructions while running in the open direction.

Close Direction Current Sense Adjustment: This multi turn potentiometer is used to calibrate the built in current sensing
feature for detection of obstructions while running in the closed direction.

Master/Slave Connection Block: This terminal block is used in conjunction with two operators to confi gure two gates to
open and close together.

Dip Switches:

#1 This switch turns the auto close timer off/on.
#2 This switch is used in conjunction with alarms and fl ashing lights that may be added to the operator. When the switch

is in the ON position, these devices will start approximately two seconds prior to the operator starting. In the OFF
position, the devices will only work while the operator is running.

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

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

#4 This switch determines right-hand vs. left-hand behavior. When looking from inside the protected area toward the gate,

the side of the drive the operator is on determines its hand of operation. In the OFF position, the operator is set for

right-hand.
#5 When turned ON, this switch will allow a one-second delay for solenoid locks to unlock before the motor starts.
#6 In the ON position, the reverse delay is three seconds. In DC operators only, this also disables the inherent DC brake

(provided the R2 brake resistor is cut, see picture above). In the OFF position, the reverse delay is 1 1/2 seconds and

the DC inherent brake is enabled.
#7 Not used at this time.
#8 This switch is used to set Master/Slave confi guration. Operators which are stand-alone or master units should be set

to OFF, while only slave units should have this switch set to ON.
