PLEASE READ THIS FIRST!
Thank you for purchasing a GTO/PRO® 4000/4200. When correctly installed and properly used, your GTO/PRO®
4000/4200 Operators will give you many years of reliable service. Please read the following information to ensure
you have the correct system for your particular needs. This manual will enable you to properly install your GTO/
PRO® 4000/4200 Automatic Gate Operators.
The GTO/PRO® 4000/4200 Operators are designed for installation on pull-to-open and push-to-open leaf
gates. The gates must not exceed 20 feet in length (per leaf) nor weigh more than 1000 pounds (per leaf) (please see
Technical Speciﬁcations on page 10). The GTO/PRO® 4000/4200 Operators can be used on vinyl, aluminum, chain
link, farm tube, and wrought iron gates. Use on solid (wood) gates is not recommended. Solid surface gates have a
high resistance to the wind. If the wind is strong enough, the operator will obstruct and stop.
The GTO/PRO® 4000/4200 Operators accommodate extra transmitters, digital keypads, solar panels, push buttons,
automatic gate locks, and other access control products. These optional accessories (see the Accessory Catalog) are
available.
The GTO/PRO® 4000/4200 Operators feature adjustable obstruction sensing. This safety feature makes the gates
stop and reverse direction within 2 seconds if they come in contact with an obstruction. MIN is the factory setting;
meaning the gates will exert the minimum force on an obstruction before they stop and reverse direction.
The GTO/PRO® 4000/4200 Operators also have an adjustable auto-close feature. After the gates reaches the fully
open position, they can be set to remain open up to 120 seconds before automatically closing. Pressing the transmitter
button at any time after the gates open fully will cause them to close immediately. OFF is the factory setting; meaning
the gates will stay open until you press the transmitter (or keypad, etc.) again.
Please call GTO at (800) 543-GATE [4283] or (850) 575-0176 for more information about our GTO/PRO®
professional line of gate operators and accessories. Our Sales Department will be glad to give you the name and phone
number of a GTO/PRO® dealer near you.

BEFORE YOU BEGIN TO INSTALL YOUR AUTOMATIC GATE OPERATOR:
Read these instructions carefully and completely to become
familiar with all parts and installation steps.
You must read the installation manual for detailed instructions on
gate operator safety and proper use of the gate operator.

IMPORTANT SAFETY INSTRUCTIONS
Because automatic gate operators produce high levels of force, consumers need to know the potential hazards associated with
improperly designed, installed, and maintained automated gate operator systems. Keep in mind that the gate operator is
just one component of the total gate operating system. Each component must work in unison to provide the consumer with
convenience, security, and safety.
This manual contains various safety precautions and warnings for the consumer. Because there are many possible
applications of the gate operator, the safety precautions and warnings contained in this manual cannot be completely
exhaustive in nature. They do, however, provide an overview of the safe design, installation, and use of this product.
CAREFULLY READ AND FOLLOW ALL SAFETY PRECAUTIONS, WARNINGS, AND INSTALLATION
INSTRUCTIONS TO ENSURE THE SAFE SYSTEM DESIGN, INSTALLATION, AND USE OF THIS PRODUCT.
Precautions and warnings in this manual are identiﬁed with this
warning symbol. The symbol identiﬁes conditions
that can result in damage to the operator or its components, serious injury, or death.
Because GTO automatic gate operators are only part of the total gate operating system, it is the responsibility of the
consumer to ensure that the total system is safe for its intended use.

To Manually Open and Close the
Gate, Follow the Procedure Below:
CAUTION: The gate will move freely and uncontrolled when the gate operator is
removed from the gate. ONLY disconnect the operator when the control box power
switch is OFF and the gate is NOT moving.

IMPORTANT SAFETY INSTRUCTIONS
For The Consumer

WARNING: To reduce the risk of injury or death:
1.

READ AND FOLLOW ALL INSTRUCTIONS. Failure to meet the requirements set forth in the instruction
manual could cause severe injury and/or death, for which the manufacturer cannot be held responsible.

When designing a system that will be entered from a highway or main thoroughfare, make sure the system is placed
far enough from the road to prevent trafﬁc congestion.

The gate must be installed in a location that provides adequate clearance between it and adjacent structures when
opening and closing to reduce the risk of entrapment. Swinging gates must not open into public access areas.

The gate and gate operator installation must comply with any applicable local codes.

I. Before Installation
1.

Verify this operator is proper for the type and size of gate, its frequency of use and the proper class rating.

Make sure the gate has been properly installed and swings freely in both directions. Repair or replace all worn or
damaged gate hardware prior to installation. A freely moving gate will require less force to operate and will enhance
the performance of the operator and safety devices used with the system.

Review the operation of the system to become familiar with its safety features. Understand how to disconnect the
operator for manual gate operation (see page 1).

This gate operator is intended for vehicular gates ONLY. A separate entrance or gate must be installed for
pedestrian use (see page 6).

Always keep people and objects away from the gate and its area of travel. NO ONE SHOULD CROSS THE
PATH OF A MOVING GATE.

Pay close attention to the diagram below and be aware of these areas at all times.

IMPORTANT SAFETY INSTRUCTIONS
Entrapment Zones for a proper Pull-To-Open installation:
Zone 1 – leading edge of the gate and the fence post.
Zone 2 – between the gate and the gate post.
Zone 3 – the path of the gate.
Zone 4 – the space between the gate in the open position and any object such as a wall, fence, tree, etc.
Zone 5 – pinch points between the opener and gate or post.

II. During Installation
1.

Install the gate opener on the inside of the property and fence line. DO NOT install an opener on the outside of the
gate where the public has access to it.

Be careful with moving parts and avoid close proximity to areas where ﬁngers or hands could be pinched.

Devices such as contact sensors (safety edges) and non contact sensors (photo beams) provide additional protection
against entrapment.

If push buttons or key switches are installed, they should be within sight of the gate, yet located at least 10 feet from
any moving part of the gate (see diagram below). Never install any control device where a user will be tempted to
reach through the gate to activate the gate opener.

Do not activate your gate opener unless you can see it and can determine that its area of travel is clear of people,
pets, or other obstructions. Watch the gate through its entire movement.

Secure outdoor or easily accessed gate opener controls in order to prohibit unauthorized use of the gate.

IMPORTANT SAFETY INSTRUCTIONS
III. After Installation
1.

Attach the warning signs (included) to each side of the gate to alert the public of automatic gate operation. It is
your responsibility to post warning signs on both sides of your gate. If any of these signs or warning decals become
damaged, illegible or missing, replace them immediately. Contact GTO for free replacements.

The gate is automatic and could move at any time, posing a serious risk of entrapment. No one should be in contact
with the gate when it is moving or stationary.

Do not attempt to drive into the gate area while the gate is moving; wait until the gate comes to a complete stop.

Do not attempt to "beat the gate" while the gate is closing. This is extremely dangerous.

Do not allow children or pets near your gate. Never let children operate or play with gate controls. Keep the
remote controls away from children and unauthorized users; store controls where children and unauthorized users do
not have access to them.

KEEP GATES PROPERLY MAINTAINED. Always turn power to operator OFF before performing any
maintenance. Clean the push-pull tube with a soft, dry cloth and apply silicone spray to it at least once per month.

Service the gate and gate operator regularly. Grease hinges, spray push pull tube with high quality silicon spray and
replace the battery every 3-5 years.

To operate this equipment safely, YOU must know how to disconnect the operator for manual gate operation
(see page 1). If you have read the instructions and still do not understand how to disconnect the operator, contact the
GTO Service Department.

Disconnect the operator ONLY when the power is TURNED OFF and the gate is NOT moving.

10.

Make arrangements with local ﬁre and law enforcement for emergency access.

11.

Distribute and discuss copies of the IMPORTANT SAFETY INSTRUCTIONS section of this manual with all
persons authorized to use your gate.

12.

IMPORTANT: Save these safety instructions. Make sure everyone who is
using or will be around the gate and gate operator are aware of the dangers
associated with automated gates. In the event you sell the property with
the gate operator or sell the gate operator, provide a copy of these safety
instructions to the new owner.
Should you lose or misplace this manual, a copy can be obtained by
downloading one from the GTO/PRO® web site (www.gtopro.com), by
contacting GTO, Inc., at 3121 Hartsﬁeld Road, Tallahassee, Florida 32303
or by calling 1-800-543-4283 and requesting a duplicate copy. One will be
provided to you free of charge.

IMPORTANT SAFETY INSTRUCTIONS
Secondary Means of Protection Against
Entrapment
As speciﬁed by Gate Operator Safety Standard, UL 325 (30A.1.1), automatic gate operators shall have an inherent
entrapment sensing system, and shall have provisions for, or be supplied with, at least one independent secondary means
to protect against entrapment. The GTO/PRO® 4000/4200 utilizes Type A, an inherent (i.e., built-in) entrapment sensing
system as the primary type of entrapment protection. Also, the GTO/PRO® 4000/4200 has provisions for the connection of
Type B2 protection to be used as the secondary type of entrapment protection, if desired.
1. For gate operators utilizing a contact sensor (e.g., safety edge sensor– Type B2) in accordance with UL 325 (51.8.4 [i]):
A. One or more contact sensors shall be located at the leading edge, bottom edge, and post edge, both inside and
outside of a vehicular swing gate system.
B. A hard wired contact sensor shall be located and its wiring arranged so that the communication between the
sensor and the gate operator is not subjected to mechanical damage.
C. A wireless contact sensor such as one that transmits radio frequency (RF) signals to the gate operator for
entrapment protection functions shall be located where the transmission of the signals are not obstructed or
impeded by building structures, natural landscaping or similar obstruction. A wireless contact sensor shall
function under the intended end-use conditions.

ENTRAPMENT ALARM (UL 325; 30A.1.1A)

The GTO/PRO® 4000/4200 Automatic Gate Operators are designed to stop and reverse within 2 seconds when the
gate comes in contact with an obstruction. Additionally, these operators are equipped with an audio entrapment
alarm which will activate if the unit obstructs twice while opening or closing. This alarm will sound for a period
of 5 minutes, or until the operator receives an intended signal from a hardwired entry/exit source (e.g. push button
control or keypad) and the gate returns to a fully open or fully closed position. Turning the power switch on the
control box OFF and back ON will also deactivate the alarm. Wireless controls such as transmitters and wireless
keypads will not deactivate the alarm.

IMPORTANT SAFETY INSTRUCTIONS
Required Safety Precautions for Gates
Install Warning Signs
Warning signs alert people of automatic gate operation and are required when installing the GTO/PRO® 4000/4200
Automatic Gate Operators. Furthermore, a walk-through gate must be installed if pedestrian trafﬁc is expected near the
vehicular gate. We recommend using the GTO Bulldog Pedestrian Gate Lock (Call the GTO Sales Department) for
controlled access.

Entrapment Protection

GTO’s inherent obstruction settings, even when properly adjusted, may not be sensitive enough to prevent bodily injury in
some circumstances. For this reason, safety devices such as safety edge sensors (or photoelectric sensors), which stop and
reverse gate direction upon sensing an obstruction, are suggested for enhanced protection against entrapment.

Warning Signs

! WARNING

The warning signs (at right) must
be installed on both sides of the
gate (see page 7 for details).

Preparation of the Gate
Step 1

The gates must be plumb, level, and swing freely on
hinges. Wheels must not be attached to the gates. The
gates must move throughout the arc without binding or
dragging on the ground. Note that gates over 250 lb.
should have ball bearing hinges with grease ﬁttings.

Horizontal Cross Member

Step 2

The fence posts must be secured in the ground with
concrete to minimize twist or ﬂex when the operators
are activated. We recommend you position the operators
near the centerline of the gates to keep them from
twisting and ﬂexing. The addition of horizontal or
vertical cross members (if one is not already in place)
to provide a stable area for mounting the gate brackets
also important.

Vertical Cross Member

Installing Mounting Hardware
Installing the Post Bracket Assembly

The post bracket is designed to work on a ﬂat fence post. Fence posts must be at least 6” square in order to mount the
post bracket.
NOTE: The best method of attaching the post bracket to metal
post is welding. Round wood posts (no smaller than 8” diameter)
may be notched to create a ﬂat surface for attaching the post
bracket.
If bolts are used to mount the post bracket, the bolts must
completely penetrate the fence post. If your fence post is wider
than 8", it will be necessary to use carriage bolts longer than
those supplied. On wood posts use a metal plate (not provided)
between the nuts and post to prevent the operator from pulling
the bolts and washers through the wood.
On masonry columns use red heads or other secure masonary
mounting hardware.
NOTE: A fence post smaller than 6" in diameter or 6" square
should be made of metal instead of wood so that it will remain
stable while the operator is moving the gate.

Step 1:

Close the gate and place your level against the
horizontal cross member. The top of the level
should be in the center of the cross member
and should overlap the fence post. Scribe
a line across the cross member and fence
post. You will use this line to help determine
position of gate and post brackets.

Step 2:

Position the post bracket on the fence post with the mounting
holes centered over the scribe line. The post bracket should be
ﬂush with the edge of the fence post closest to the gate (see
illustration). Mark the position of post bracket holes on the
fence post.

Step 3:

Drill holes in fence post as marked using a 1/2" drill bit.
Install the post bracket using the 1/2" x 10" carriage bolts,
1/ " washers, and lock nuts (provided).

Step 4:

Place the end of post pivot bracket with two holes inside
the post bracket. Align the back hole in the post pivot
bracket with back hole in the post bracket. Insert 1/2"
x 33/4" hex head bolt through post pivot bracket and
post bracket and secure with washer, large bushing,
lockwasher and nut.

Step 7:

Open the gate to the desired open position. Position the operator so
that the gate bracket rests against the gate along the level scribed
line. Check the clearance between the operator and the gate.
The operator should only make contact with the gate at the gate
bracket. See illustration at right for examples of clearance.

Pinch Area

When you feel that you have the best position for the post pivot
bracket in the open position, insert the bolt through the aligned
holes of the post bracket and post pivot bracket to hold it in place.

Gate in the
OPENED POSITION

Clamp the gate bracket to the gate using c-clamps or another type
of clamp.

2" minimum

IMPORTANT: While determining the position of
the post pivot bracket, be sure that the position allows
for minimum 2 inches of clearance between the gate
and the operator in both the open and closed positions,
as shown in Steps 7 & 8 . This clearance will give the
operator the most efﬁcient leverage point for opening
and closing the gate and more importantly provides the
least possible pinch area.

Step 8:

Gate in the
CLOSED POSITION

2" minimum

Remove the clevis pin from
the front mount and while
supporting the gate operator,
swing the gate and gate
operator to the closed position.
With the gate and gate operator
in the closed position check
the clearance and be sure that
the gate operator is not binding
at the post pivot bracket.

Pinch Area

If you don't have 2 inches of clearance or the gate operator is binding on the post pivot bracket, remove the bolt in
the post bracket and readjust the pivot bracket until you can achieve the proper clearance.
With the post pivot bracket in the optimum position for clearance and freedom of movement, replace the bolt in a
post bracket adjustment hole and return the operator to the open position and recheck the gate operator level and
clearance. Make sure the gate bracket is clamped securely.

Installing the Gate Bracket
Step 9:

Move the operator away from the gate bracket. The mounting holes should be centered over the scribe line. Mark the gate in
the center of the gate bracket holes. Remove the gate bracket and drill the 1/2" holes in the gate cross member and attach the
gate bracket using the 1/2" x 23/4" bolts, washers and nuts.

DUAL GATE INSTALLATION
You will need to install the GTO/PRO 4200 SLAVE operator
arm on the second gate following the same steps you did to
install the GTO/PRO 4000 MASTER operator arm. Begining on
page 13, Step 1 through page 17, Step 10. When the second
gate operator is installed go to the page 18 and continue.

Installation of the Closed Position Stops
The GTO/PRO® 4000/4200 Gate Operators ﬁrmly hold the gates in the closed position using
positive stops. The positive stops help stabilize the gate leaves in the closed position. To further
enhance stability and security, we strongly recommended using an optional GTO/PRO® Automatic
Gate Lock (see Accessory Catalog) with your dual gates.

IMPORTANT: You need
to determine which side of the
driveway you will mount the
control box. From this point on
the gate and gate operator on the
same side as the control box will
be referred to as the MASTER
gate and gate operator. The gate
and gate operator on the opposite
side of the driveway from the
control box will be referred to
as the SLAVE gate and gate
operator.

Powering the System

Installation of the Transformer
IMPORTANT:
•

The transformer is designed and intended for indoor use. If the transformer can be plugged only into
an outside electrical outlet, a weatherproof cover or housing (available at local electrical supply stores)
must be used.

•

All low voltage wire used with the GTO/PRO® 4000/4200 Gate Operator must be 16 gauge dual
conductor, multi-stranded, direct burial wire (see page 23 and the Accessory Catalog). Do not run
more than 1000 feet of wire.

•

If your gate is more than 1000 ft. from an ac power source, you will need to use from 10 to 30 watts
of solar charging power to charge the battery (see Accessory Catalog). Refer to the Solar Panel and
Gate Activity chart below.

OPTIONAL Solar Panel and Gate Activity
The table and map illustrate
the maximum number of
gate cycles to expect per
day in a particular area
when using from 15 to 30
watts of solar charging
power. (see Accessory
Catalog). The ﬁgures
shown are for winter
(minimum sunlight) and do not account
for the use of any accessory items.
Accessories connected to your system will
draw additional power from the battery.

ON/OFF Switch

Step 2

Select the electrical outlet into which you will plug the transformer.
Measure the distance from this outlet to the control box following the
path where the wire will be laid. After you have measured how much
wire is needed, cut the wire to the appropriate length. (Not more than a
1,000 feet).
22

IMPORTANT INFORMATION ABOUT LOW VOLTAGE WIRE

The only wire acceptable for use with GTO products is 16 gauge multi-stranded, low voltage, PVC
sheathed wire. This particular gauge enables the transformer to provide an adequate charge through the
control board to the battery at distances up to 1000 ft.

DO NOT use telephone wire or solid core wire. Unlike multi-stranded wire, these types of wire are

inadequate for use with your gate operator system. Telephone wire and solid core wire do not deliver
enough voltage for your gate operator to function and will cause the system to go into a condition known
as "low voltage lockout."

NEVER splice wires together. Splicing permits corrosion and seriously degrades the wire's ability to
carry an adequate current.

12 V Battery

Step 3

Lay the measured length of low voltage wire in a trench following a path from
the selected electrical outlet to the control box. Wires coming up from the
ground should be run through PVC conduit to protect them from lawn mower
blades, weed eaters, and grazing animals. Be sure to bury the wire laid in the
trench.

TURN CONTROL BOX ON
Your GTO/PRO® 4000/4200 has two Limit Settings
1) OPEN Limit setting: (Gate in the OPEN POSITION / FACTORY SET NOT ADJUSTABLE) The open limit setting is
the fully open position.
2) CLOSED Limit setting: (Gate in the CLOSED POSITION) To achieve optimum closed position, you are required
to complete the following SEVEN STEPS:

Step 1

Conﬁrm that the power switch is in the ON position, and the gates are in the OPEN POSITIONS.

Step 2

Activate your operators by pressing the entry transmitter button. Your gates should now be moving from the fully open
positions toward their closing position. Prepare to STOP gate by pressing the entry transmitter button again when the ﬁrst
gate reaches the desired closed position. This step may be repeated until desired close position is achieved. Once the desired
CLOSED position has been achieved, proceed to step 3.

Step 3

With the ﬁrst gate in the desired closed position. Program the closed limit setting by setting the number 4 DIP switch on the
DUAL MODES switches to the OFF position (if the MASTER gate closed ﬁrst) or the ON position (if the SLAVE gate closed
ﬁrst) then PRESS & HOLD the “SET LIMIT" button on the control board for 5 seconds.

Step 4

Press the transmitter button and allow the gates to return to the fully open position. YOUR FIRST GATE’S CLOSED
POSITION LIMIT IS NOW PROGRAMMED.

Step 5

Activate your operators again by pressing the entry transmitter button. Your gates should now be moving from the fully
open positions toward their closing position. The ﬁrst gate will stop at the spot you just programmed and the second gate
will continue to close until you press the transmitter button again. The optimum CLOSED POSITION for the second gate is
when it closes ﬁrmly, without excess tension, against the ﬁrst gate. This step may be repeated until desired close position is
achieved. Once the desired CLOSED position has been achieved, proceed to step 6.

Step 6

Setting Your Personal Transmitter Code
All GTO transmitters are set to a standard code at the factory and are ready to operate your GTO/PRO® 4000/4200 Gate
Operator. For your safety and security, however, we strongly recommend that you replace the factory setting with your own
personal code. Follow the directions below:

1. Remove the Transmitter Cover
Grasp the sides of the access cover and slide it away from the transmitter button (see
illustration). When the access cover is removed, the battery and the DIP switches will be
exposed. To set a new code, use a small screwdriver to move the switches.

Installing the Receiver
Use the transmitter to check the range of the receiver before permanently mounting it.
Consider the following when mounting the receiver:
• Standard receiver cable length is 10 feet (receivers with a longer cable are available as special
order items; call the GTO Sales Department). NEVER splice receiver cable!
• Run the cable through PVC conduit to protect it from damage.
• DO NOT run cable through metal conduit because the receiver signal range will be decreased.
• DO NOT run cable in conduit containing ac wiring.
• DO NOT mount receiver on a metal fence or post; doing so will decrease signal range.
• The receiver range can vary from 50 to 100 feet depending upon weather, topography, and
external interference.
• DO NOT mount upside down.
FCC Regulation
This device complies with FCC rules Part 15. Operation is subject to the following conditions:

A "Push-to-Open" gate opens out from the property.
If you have a pull-to-open gate (gate opens into the property), return
to page 13.

Post Bracket

In a PUSH-TO-OPEN installation the operators are installed while
the gates are in the closed position.
NOTE: An optional 12" long Post Pivot Bracket (R4KPTO) is
available for installations that need a greater distance to achieve the
safe gate and gate operator clearance (2 inches).

1/2" Washer
1/2" Lock Washer
1/2" Nut

Step 1

Post Pivot Bracket

With the gates closed, adjust the post bracket assembly and the gate
bracket until the operator is level. While holding the operator level,
use C-clamps to temporarily keep the post bracket assembly and
gate bracket in their respective positions on the fence post and gate.

IMPORTANT: While determining the mounting point for the post
pivot bracket assembly be sure that the position allows for maximum
clearance between the gate and the operator in both the open and closed
positions, as shown in the diagrams below. This clearance will give the
operator the most efﬁcient leverage point for opening and closing the
gate and more importantly provides the least possible pinch area.

Gate in the Open Position

Step 2

After verifying that you have the best position
for the post pivot bracket, insert the 5/16" x 1 3/4"
bolt through the aligned holes of the post bracket
and post pivot bracket and fasten it with the 5/16"
washer and nut.

Pinch Area

2" minimum

IMPORTANT: If you loosened the clamp on
the post bracket to achieve the optimum position,
tighten it in its new position and recheck the gate
bracket with the gate in the open position (move the
gate bracket and re-clamp it if necessary).
Gate in the Closed Position

Pinch Area

2" minimum

Step 3

With the gate in the fully closed position and the operator retracted, swing the operator to the gate. Mark reference points
for bolt holes on gate cross member through middle of gate bracket slots. The operator must be level. Drill 3/8" holes into
the gate cross member as marked. Fasten gate bracket to cross member using (2) 3/8" x 3" bolts, washers, lock washers, and
nuts. Attach the operator to the post bracket assembly and gate bracket using clevis pins, bushings, and hairpins clips.

Maintenance & Troubleshooting
If your gate operator does not function properly after it is installed, use this guide
before calling the GTO Service Department.
• On all gates weighing 250 lb. or more, routinely grease the ball bearing hinges at least 4 times a year; more
frequently if the gates are near a coastal area.
• Keeping a few mothballs in the control box will discourage insects from entering it and damaging the control
board.
• Clean the push-pull tube with a soft, dry cloth and apply silicone spray to it at least once per month.
• While oxidation is a normal part of weathering of equipment that is exposed to the elements, we recommend
you apply silicone spray on the front and rear mounts to minimize this effect.

If the Operator Does Not Work
Check the Green LED on the Control Board:
IF THE LED IS OFF: This condition indicates a transformer power failure.

1. Test the transformer for voltage with a voltmeter. The acceptable range can be found in the VOLTAGE
LIMITS chart on the next page. If the transformer test shows no voltage, then test the electrical outlet for
voltage. If the outlet test shows voltage, then the transformer is dead and must be replaced. Allow the new
transformer 12 hours to charge the battery before using the gate operator.
2. If the transformer test shows voltage, check the POWER IN terminal block on the control board for voltage.
If the terminal block shows no voltage, look for broken or spliced wires.

Check the Red STATUS LED on the Control Board:
IF THE LED IS ON: but the unit is not working.

1. Check the battery in your transmitter and replace with a fresh one if needed..
2. Verify that the power cable is securely connected.
3. Replace the control board fuse if it is blown (25 ampere fuse only - DO NOT USE
A HIGHER RATED FUSE!).
IF THE LED IS OFF:
1. Make sure the ON / OFF switch at the bottom of the control box is set to ON.
2. Check all connections for looseness and corrosion.

If the Operator is Working
The Gate CLOSES Then Opens Again on its Own:
1. Check the position of the mounting brackets and readjust if necessary.
2. Check the gate for binding or hinge damage.

The Gate OPENS Then Closes Again on its Own:
1. Check the position of the mounting brackets and readjust if necessary.
2. Check the gate for binding or hinge damage.

Column Installation Information
IF THIS OPERATOR WILL BE USED WITH GATES THAT ARE MOUNTED ON
MASONRY, BRICK, OR ROCK (etc.) COLUMNS:
READ THE FOLLOWING CAREFULLY BEFORE PROCEEDING
A.

The simplest solution is to install the operator in a push-to-open conﬁguration. The minimum clearance is easier
to achieve and clearance is no longer a problem, since the operator will be pushing the gate away from the column
instead of pulling it toward the column. It is recommended that you place a steel plate between the operator
mounting brackets and masonry surface for additional strength.

If a push-to-open installation is impossible due to trafﬁc hazards, terrain, etc., another option is to re-hang the gate.
You may hang it on a post, either in the center of the column or at the back corner, or move the gate to the back
corner of the columns.

The most difﬁcult solution is to cut a notch in the column to accommodate the operator and power cable. This job is
NOT for the inexperienced!
