INTRODUCTION
This operator is intended to be installed on vehicular Class I or Class II gates as defined by
UL 325. Maximum gate load not to exceed 250 pounds.
PLEASE READ THIS ENTIRE MANUAL CAREFULLY PRIOR TO INSTALLATION.
In doing so, along with performance of the installation in step-by-step order, you
will achieve optimal results. We strongly recommend that all installation and
service personnel pay particularly close attention to the safety systems section of
this manual and UL325. In addition to the current sense feature that is provided,
other safety devices are necessary to make each particular installation as safe as
possible to reduce the risk of personal injury and/or property damage. A trained
and authorized service technician or the factory should be consulted for assistance.
Cautions - Very Important
Do not attempt to enter the gate area while the gate is moving. Wait until
the gate comes to a complete stop.
Operate the gate only when it is fully visible, free of persons or obstructions,
and properly adjusted.
Do not allow children to play in the area of the gate. Do not allow anyone
to ride on the gate.
Do not allow children to play with the remote control or any other
activation device.
Do not attempt to "beat the gate" while the gate is opening or closing.
This is extremely dangerous.
Test the current sense feature and all safety devices regularly to insure
correct operation.
Study the entire Safety Section on pages 17-21 paying particularly close attention
to the Entrapment zones, and be aware of these areas not only during use but also
during any adjustments to the unit.
Other Safety Standards
All control stations should be located at least 6 feet from any moving part
of the gate or operator.
Do not ever install any control device where a user will be tempted to reach
through the gate or fence to activate a gate.

GENERAL REQUIREMENTS
General hand/tools such as combination wrenches, tape measure, level, clamps, etc. are
required. Your particular installation may require a drill or other hardware not provided.
Welding by a qualified welder is the recommended method of securing the linear actuator
mounts to the gate and hinge post. Bolt on brackets are options, but they must be very
securely attached (i.e. carriage bolts with lock nuts and washers). Lag type bolts are not
recommended. Loose or unstable operator mounts will result in improper operation.
BATTERY REQUIRED FOR OPERATION (NOT INCLUDED).
We recommend a 12-volt deep cycle marine battery. The actuator and charging device
harness supplied with the operator is designed for bolt type post such as ones found on most
marine batteries.
IMPORTANT CAUTIONS:
1. Do not perform any welding with the actuator cable plugged into the control
board or the battery connected. Serious damage to the control board and/or
battery will occur if attempted.
2. Always disconnect the battery power from the unit prior to connecting any devices.
GATE QUALIFICATIONS/APPLICATIONS
GATE LENGTH/WEIGHT
This gate operator is rated for vehicular class I and class II swing gates up to 10 feet in
length and up to 250 pounds in weight as defined by UL325. If your gate exceeds either one
of these limits, please consult a qualified technician or the factory for alternative solutions.
(Example: convert one 20' gate into two 10' gates and use dual gate operators.)
Note:
The total gate opening normally cannot exceed 110 degrees.
Consult a service technician or the factory if greater opening is required.
GATE CYCLES PER DAY
Solar charged systems should not exceed 20 complete open/close cycles per day
without additional solar panels. This actuator type opener, whether AC or Solar
charged, should never be used in applications which exceed 100 complete open/close cycles
per day. Cycles can be decreased by holding the gate open during high cycle time periods. If
more cycles are required, a high traffic gate opener should be used.
-3-
IMPORTANCE OF A PROPERLY DESIGNED GATE
As a general rule a gate, which is to be automatically operated, must be stronger and
smoother than one, which will be manually operated. Since the gate is a major component
of the system, great care and concern must be given to the gate design.
A GATE OPERATOR CANNOT OVERCOME A POORLY DESIGNED GATE.
A. Does the gate swing smoothly without binds or excessive resistance? Swing gates
should swing level and plumb to prevent the operator from having to lift the gate open
or closed. Swing gates should not require a wheel to support them. Wheels usually
create drag, which will cause operator problems. A wheel is generally a sign of a
weak hinge system or a weak gate frame.
B. Is the gate frame of substantial strength without excessive weight? Will the frame
withstand normal wind load conditions without sway or vibration? Will the gate
close correctly without being hand-guided or lifted to close?
C. Are the hinges suited for the number of cycles expected per day? We recommend
bearing type hinges to reduce friction drag.
D. Will a reinforcement brace be required to attach the operator to the gate or does a
suitable cross member exist in the gate design?
If any of these problems exist, they must be corrected to achieve a reliable automatic gate
system.
MOUNTING SITE REVIEW
Installers should ask themselves these questions prior to installation and predetermine the
solution to any problems, which may occur.
A. Does sufficient space exist for mounting and future servicing of the operator and
control box?
B. Will the unit push the gate open to the outside or pull the gate open to the inside?
C. How will the actuator mounts be secured at the hinge and to the gate?
D. How will the control box be mounted securely enough to support the weight of the
battery and can it be located within 8 feet to prevent splicing of the actuator cable?
E. How will power be brought to the control box if AC charged?
F. How and where will the solar panel mount if solar charged so that optimum sunlight is
received?
G. How will exterior control wiring be brought to the control box?
H. Have all safety concerns been addressed? (See Safety Section Pgs. 17-21)

Mounting Control Box/Actuator Cable Splicing
NOTE: Push to open installations. See page 10 for more details.
Correct – Install control box to fence by welding
or screws. Keep in mind that the actuator cable
is 8’ in length (avoid splicing cable if possible) if
splicing is necessary water tight splices are a must.
if drilling is required remove control board and all
electronic devices to avoid damage from shavings.
Incorrect – Do not mount in areas by automatic
sprinklers or flood prone areas. It is important that
all electronics in the control box remain dry. Control
box should be mounted at least 6 feet from gate
Figure 6A
After securely mounting control box install battery and all electronic components. Route
actuator cable through the bottom of control box, do not connect to battery or control board at
this time.
-9-
Splicing For Actuator Cable
STAR I Single Gate Wiring (only if required)
If 8’ actuator cable must be spliced a water tight junction box
must be used to prevent moisture from splice. The wire used for
the splice should be no smaller than the actuator cable wire
provided. Use only approved wire nuts or crimp splices for
connection. Make second splice inside control box.

STEP 6 Installation of Charging Source
SOLAR PANEL
Locate and mount the solar panel bracket so that the panel faces southwest and maintains the preformed 45degree angle. The standard cable is 10' in length and must feed in through the bottom of the control box. Pay
attention to the distance when determining you’re mounting location. Although the cable can be extended with
watertight connectors, charging power is diminished. Sometimes it is necessary to locate the panel farther away
to achieve optimum sunlight, but consider that optimum sunlight might not mean optimum charging if the
distance is to great. Use #16 gauge wire or larger and keep length as short as possible.

NOTE: Avoid shaded areas if possible. Panels should face southwest for optimum
charging. See explanation above for details.
AC CHARGER
Locate and install the AC battery charger inside the control box. The charger requires a receptacle for 110-volt
AC supply; recommended location is inside the control box. A licensed electrician per local building codes
should install the receptacle.
Note:
USAutomatic recommends an AC surge protector on all 110-volt installations.
Especially in lightning prone areas.
Do not connect battery wires from actuator/control board at this time.

STEP 7 Installing Safety Placards
Mount safety placards on gate. Two signs are provided. Place one sign on each side of the gate where it will be
highly visible to anyone on either side of the gate.
STEP 8 Installing Secondary Entrapment Siren
The secondary entrapment siren connects to the control board (see page 33). This siren is very loud and will be
activated anytime the current sense circuit stops the gate twice prior to reaching a fully open or close limit. The
reset button on the control board (see page 13) must be pushed to turn off the siren, and reset the control board.
-11-
STEP 9
Making Final Adjustments
In order to make final adjustments, a signal device such as a radio control should be used. The control
board is equipped with a pushbutton for this purpose. The button is designed to give an open/close
signal. The gate will open if closed or close if in the open position. A signal in mid-travel will stop the
gate.
•
If your unit was purchased with a radio receiver, it is important that you change the dipswitch code
settings on your receiver and on all of your transmitters. Please read the instructions found with
your transmitter or consult a dealer for assistance.
IMPORTANT NOTES
1.
2.
3.
Locate the actuator cable plug and be aware that you may need to disconnect it if the cylinder over
travels the desired stop points. You should be able to stop the motor with a signal from your
transmitter without having to disconnect the plug, but in cases of incorrect wiring, the plug can be
used as an emergency power shut-off.
Locate the sensitivity adjustment. We intentionally set the sensor at a highly sensitive setting. This
may need to be adjusted to achieve gate movement without tripping the sensitivity circuit and
causing the gate to reverse direction. See page 13 for details.
Study the limit switch section and instructions on adjusting the limit switches prior to battery hook
up. See page 14 for details.

Adjust the sensitivity adjustment so that the gate reverses when it hits a solid
object. Do not turn the dial beyond the stop points at 0 and 10.
If sensitivity feature is activated twice before reaching a fully open or close limit
the operator will stop operating and the secondary entrapment siren will sound (if
connected see page 26 for wiring) and the control board will require a manual
reset using the reset button on the control board.
Remember if the gate reverses direction when operating without hitting and obstruction,
then minimizing sensitivity (increasing pressure) may be required. Do not increase any
more than necessary.
CAUTION: To reduce the risk of injury, USAutomatic strongly recommends the installation
of additional safety devices such as Photo Eye Sensors and Safety Edges.
Consult an authorized installing dealer or the factory for a complete explanation
of options and see the Safety Section of this manual on pages 17 to 21.

LIMIT SWITCHES
The limit switch adjustments are located on the side of the actuator. Remove the dust plug
to make adjustments. The normal settings from the factory allow for 16" of travel. You will
most likely have to adjust the limits for your installation. The adjustments are labeled
"Extend" and "Retract" on the dust plug. A 7/32 nut driver (provided) is required.
NOTE:
ALL ADJUSTMENTS SHOULD BE MADE IN THE MID TRAVEL (1/2 OPEN)
POSITION. DO NOT FORCE THE ADJUSTMENT SCREWS TO TURN

SAFETY SECTION
INSTALLATION
Install the gate operator when:
The operator is appropriate for the construction of the gate and the usage class is correct for the installation.
All exposed pinch points are eliminated or guarded.
Only install on vehicle gates, pedestrians must be supplied with a separate access opening.
The gate is installed in a location where enough space is supplied between adjacent structures and the gate that when
opening or closing the chance of entrapment is reduced.
Swing gates shall not open into public access areas.
The gate is properly installed and swings freely in both directions. Do not over adjust the sensitivity adjustment to
compensate for an improper gate installation.
Locate all controls at least six feet away from the gate to eliminate the chance of the person operating the gate from
coming in contact with the moving gate. Do not install external buttons, which can be used to operate the gate within
the reach of children.
All placards must be installed one on each side of the gate visible in the gate area.
Contact sensors used for secondary entrapment safety devices and their wiring must be installed in a manner protects
them from mechanical damage.
Non-Contact sensors used for secondary entrapment safety devices must be located so that the signal from the
transmitter to the receiver is not interfered with by adjacent structures. All exposed wiring must also be protected
from mechanical damage.
WARNING: TO REDUCE THE RISK OF INJURY OR DEATH
1.
READ AND FOLLOW ALL INSTRUCTIONS
2.
Never let children operate or play with gate controls. Keep remote control away from children.
3.
Always keep people and objects away from the gate.
4.
NO ONE SHOULD CROSS THE PATH OF A MOVING GATE.
5.
Test gate operator monthly. The gate must stop and reverse directions upon contacting a rigid object or when
the secondary entrapment device is activated.
6.
After all adjustments have been made to the limit switches, sensitivity (current sense) circuit, secondary
entrapment devices and all other external devices installed, the safety devices must be checked again. Failure to
adjust and retest the gate operator can increase the risk of injury or death.
7.
Verify that the emergency release (manual release) pin can be easily removed. This should only be checked when
power is disconnected from the operator.
8.
KEEP GATES PROPERLY MAINTAINED. Read the installation/owners manual.
9.
THE ENTRANCE IS TO BE USED BY VEHICLES ONLY. Pedestrians must use a separate entrance.

SAFETY SECTION
All safety features required by UL 325 are incorporated in the capabilities of all
USAutomatic Control boards and should be utilized, including but not limited to, safety edges, photo
electric eyes, reverse sensing, and motion sensing.
Cautions - Very Important
Do not attempt to enter the gate area while the gate is moving. Wait until the gate comes to a
complete stop.
Operate the gate only when it is fully visible, free of persons or obstructions, and properly
adjusted.
Do not allow children to play in the area of the gate. Do not allow anyone to ride on the gate.
Do not allow children to play with the remote control or any other activation device.
Do not attempt to "beat the gate" while the gate is opening or closing. This is extremely
dangerous.
Test the sensitivity feature and all safety devices regularly to insure correct operation.
Study this entire Safety Section paying particularly close attention to the entrapment zones shown
below and be aware of these areas not on during use but also during any adjustments to the unit.

Zone 2 A safety edge may also be utilized here but the best remedy is to eliminate pinch
points when designing the hinges. Most injuries at this point result from
negligence, such as reaching through the hinge area or the gate to activate a button,
key switch, etc.
Catch Post
Single or Dual Safety Edges
as required. Edges should
be wired to Secondary

Periodic Service
All gate operators require periodic checking and adjustments by a qualified technician of the
control mechanism for force (load), speed and sensitivity. All external accessories and secondary
safety devices must be checked. Secondary safety devices need to be checked at least once a
month for proper operation.
Periodic checking is also advised for the following:
1.
Battery cells water level. (use distilled water if needed)
2.
Hinges and pivot points need to be greased.
3.
Bolts for correct tightness.
4.
Inspect weld points for cracks or other defects.
5.
Inspect wiring for cuts, knicks or other defects.
6.
Inspect hinge post, ensure that it is not twisting or moving.
Troubleshooting Guide
Introduction
The USAutomatic control board is equipped with two unique features to assist in troubleshooting a gate
system.
1. The first and most helpful is the series of LED indicating lights. These lights will help to identify
problems with the actuator limit switches and the receiver input. To use the indicators, press and hold
the Push Button Led button on the control board. (The lights are not active at all times to save battery
life). Any circuits or limit switches that are activated will be obvious by the illumination of the adjacent
LED indicating light.
2. The second feature to assist in troubleshooting is the on board Open/Close Pushbutton.

Loop Size Chart
The loop size is based on the width of the driveway. If the driveway were 14' wide, the loop would be a
6'x6', the minimum. This is determined by subtracting 4' off of each side of the drive, which would leave
you 6'.
See chart below for number of turns per loop size, plus lead in.
The loop itself should contain between 90 & 125 feet of wire in the loop, plus lead in.

The location of the loop is also important. If a loop is located too close to the gate, it will detect the
gate itself, giving false operation. If the loop is too far away from the gate a small vehicle might not be
detected. Loops should be approximately 5' from the centerline of a gate when closed. See Loop
Position on previous 2 pages.

Loops
Other Loop Detector Facts
1. Always clean saw cuts thoroughly with water, air or brush to remove all debris prior to installing wire.
2. Recommended loop wire is TFFN #16 gauge stranded wire. It is available at electric supply
distributors.
3. No splices are permitted in the loop or loop leads. One continuous wire should be used.
4. Lead wires should be twisted a minimum of 4 twists per foot to eliminate false sensing. Twists should
begin at the edge of the loop and continue to detector.
5. Do not use metal or sharp objects to push the loop wire into the saw cut. The slightest nick or cut in the
insulation will cause the loop to ground out and malfunction. To test for shorts, use a megohmeter or
"Megger" between either loop lead and earth ground with both leads disconnected from the detector.
The resistance should be greater than 50 megohms.
6. Use siliconized caulk for backfill. Gray for concrete, black for asphalt. 25-Year life rating is preferred.
7. Never set adjacent loops on the same frequency. False activation will occur.
8. Almost all brands of detectors have an external or internal sensitivity adjustment. Usually the factory
setting is sufficient if internal adjust type. Be very careful and use extreme caution when decreasing
sensitivity.
9. Most false activations are caused by an improperly installed loop or a shorted loop. The loop should be
tested and validity determined before adjusting sensitivity. See # 5 above.
10. Most detectors used in the gate business are fail-safe. This means that if the loop fails, the gate will be
given a continuous signal. When power is disconnected from a detector, the signal output is also given.
11. ASB, or automatic sensitivity boost is now available on most detectors. This feature should be
activated if large truck or trailer traffic is likely.
