Thank you for purchasing the GTO/PRO® 3000/3200 gate operator system. When correctly installed and properly
used, your GTO/PRO® 3000/3200 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® 3000/3200 Automatic Gate Operators.

The GTO/PRO® 3000/3200 Operators are designed for installation on a pull-to-open dual leaf gates (gates
that open into the property). By purchasing an accessory bracket, the GTO/PRO® 3000/3200 Operators can
accommodate push-to-open dual leaf gates (gates that open out from the property). The gates must not exceed 16
feet in length (per leaf) nor weigh more than 650 pounds (per leaf) (please see Technical Specifications on page 11).
The GTO/PRO® 3000/3200 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® 3000/3200 Operators accommodate extra transmitters, digital keypads, solar panels, push buttons,
automatic gate locks, and other access control products. These optional accessories (see the enclosed GTO/PRO®
Accessory Catalog) are available.

The GTO/PRO® 3000/3200 Operators feature adjustable obstruction sensing. This safety feature makes the gates
stop and reverse direction within 2 seconds when 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® 3000/3200 Operators also have an adjustable auto-close feature. After the gates reache 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 [phone] 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

Clevis Pin

Hairpin Clip

Gate Bracket

Front or Rear Mount

Bushing

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
remove from the gate. ONLY disconnect the operator when the control box power

switch is OFF and the gate is NOT moving.

Disconnecting the Operator

1. Turn control box power switch OFF.

2. Remove hairpin clip, clevis pin, and bushing
from either the front or rear mounting point.

3. Remove the opener from the mount.

The gate can be opened and closed manually
when the operator is disconnected.

NOTE: Substitute a Pin Lock for the clevis pin on the front
mount of the gate operator to prevent unauthorized removal of
the operator from the gate (see Accessory Catalog).

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.

2. 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.

3. 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.

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

I. Before Installation

1. Verify the operators are proper for the type and size of gate, its frequency of use and the proper class rating.

2. Make sure the dual 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.

3. 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).

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

5. Always keep people and objects away from the gate and its area of travel. NO ONE SHOULD CROSS THE

PATH OF A MOVING GATE.

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

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

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

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

4. 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 operator.

5. Do not activate your gate operator 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.

6. Secure outdoor or easily accessed gate operator 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.

2. 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.

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

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

5. 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.

6. 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.

7. 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.

8. 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.

9. 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® website (www.gtopro.com), by

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® 3000/3200 utilizes Type A, an inherent (i.e., built-in) entrapment sensing
system as the primary type of entrapment protection. Also, the GTO/PRO® 3000/3200 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® 3000/3200 Operatosr 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.

Required Safety Precautions for Gates

Install Warning Signs

Warning signs alert people of automatic gate operation and are required when installing the GTO/PRO® 3000/3200
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

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

Pull-to-Open Gates (Gate Opens into the Property)

The diagram shown below is an example of a pull-to-open installation on a chain link fence and dual gates. Mounting the
operators on a masonry column requires special procedures; see Column Installation Information on page 39 if you intend
to mount the operators on columns. Furthermore, if you have push-to-open gates, you will need to purchase two (2) push-
to-open brackets (see Accessory Catalog) to properly configure your system. See Push to Open Installation on page 33
before proceeding.

Preparation of the Gate

Step 1

The gates must be plumb, level, and swing freely on
their hinges. Wheels must not be attached to the gates.
The gates must move throughout their arc without

binding or dragging on the ground. Note that gates
over 250 lb. should have ball bearing hinges with grease
fittings.

Step 2

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

The position of the post bracket determines the leverage and efficiency of the operator. The post bracket position also sets the
clearance between the operator and gate in the open and closed positions (minimum 2 inches).

The curved design of the post bracket works well for installations on round and square fence posts. Because the post bracket
carries the entire thrust of the active operator, bolts that completely penetrate the fence post must be used.

On wooden posts, place a metal plate or washer
(not supplied) between the nuts and the fence
post to prevent the thrust of the operator from
pulling the bolts and washers out of the wood.

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.

On round posts of 6" diameter or larger, the post pivot bracket may
not be necessary for the installation. In this instance, the two post
brackets are mounted by themselves.

IMPORTANT:

We strongly recommend using steel pipe, wood or metal to reinforce thin walled tube gates or wood to reinforce panel gates
as shown. These reinforcement methods will prevent damage to the operator and gate when the operator is installed.

Step 3

Insert the 3/8" x 2" bolt through
the center hole of the post
brackets and post pivot bracket

as shown. Fasten a 3/8" lock
washer, 3/8" washer and 3/8" nut

on the end of the bolt. DO NOT
overtighten the nut because the
post pivot bracket will have to be
adjusted later.

NOTE: The following steps are
intended for pull-to-open gate
installations. If you are mounting
your operators on a push-to-open
gate (e.g., a gate on a sloped
driveway) you will need to purchase
two Push To Open brackets (see

Accessory catalog). Also, see Push-
to-Open Installation beginning on

page 33.

Step 4

Attach post bracket assembly and gate bracket to the operator with the clevis pins and bushings. Secure the clevis pins with
hairpin clips.

Step 5

With the gate in the open position (up to 110º from its closed position) and the operator fully retracted, adjust the
post bracket assembly and 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.

Be sure gate opener
and bracket don't bind.

IMPORTANT: While determining the mounting point for the post pivot bracket assembly, 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 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.

Step 6

When you feel that you have the best position for the post pivot bracket in the open position, insert the 5/16" x 1-3/4" bolt
through the aligned holes of the post bracket and post pivot bracket to hold it in place. 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.

If you don't have 2 inches of clearance or the gate operator is binding on the post pivot bracket, remove the 5/16" x 1-3/4"
bolt and readjust the pivot bracket until you can achieve these important clearances.

With the post pivot bracket in the optimum position for clearance and freedom of movement, reattach the operator to the gate
bracket in the open position and recheck the gate operator level and make sure the brackets are clamped securely.

TIP: Turning the pivot bracket over gives

more hole alignment options for the post
pivot bracket assembly. You can also move
the entire post pivot bracket assembly to
different positions on the gate post to help
achieve the proper clearances.

The GTO/PRO® 3000/3200 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 gate.

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.

Illustration A

Step 1

Attach the horizontal closed position stop plate to the
MASTER gate leaf.

Detach the gate operators from the gates and move the
gates to their closed position (Illustration A). Using
appropriate hardware for your type of gate (U-bolts for
tube or chain link; screw or bolts for wood or metal)
attach the closed position stop plate (horizontally) about
mid height on the MASTER gate frame. Do not tighten
it completely at this time. Slide the stop plate toward the
frame of the SLAVE gate leaf until they touch (Illustration
B). Once you have moved the stop plate to the correct
position, tighten its hardware completely.

The ground stop needs to be positioned near the end of the
gate as shown in Illustration A and may be made of metal
or concrete and should be firmly secured in the ground (we
recommend setting it in concrete).

Illustration C

Step 3

Attach a vertical closed position stop plate to the SLAVE
gate.

Using appropriate hardware for your type of gate attach the
vertical closed position stop plate to the SLAVE gate frame
at the point where it will come in contact with the ground stop post.. Do not tighten it completely at this time. You must slide
the closed position stop plate toward the ground stop until they touch (Illustration C). Once you have moved the stop plate to
the correct position, tighten its hardware completely.

NOTE: For a push-to-open installation (gate opens out from the property) attach the closed position stop plate to the outside
of the gate.

At this stage of the installation, the operators should be installed on the
gate leaves and closed position stops should be in place.

Single Battery

Installed Horizontally

with terminals on the right.

Dual Batteries

Installed Vertically

with terminals on bottom

.

Step 1

Mount the control box using the screws (provided) or another
secure mounting method. The control box must be mounted at
least 3 feet above the ground to protect it from rain splash,
snow, etc., and at least 3 feet from an AC power source to

prevent electrical interference.

NOTE: The battery that came with your GTO/PRO®

3000, MUST be placed in the top (horizontal) battery
slot with the terminals on the RIGHT. The extra
(vertical) battery slot is for an optional second battery.
An optional second battery can be used for solar and/or
high traffic applications, if needed..

Step 2

Make sure the control box power switch is in the OFF
position. The ON/OFF Switch is located on the bottom of
the control box. Remove the control box cover and slide
the battery into position with its terminals to the RIGHT
(see illustration). Connect the BLACK battery wire to the
NEGATIVE (–) battery terminal. Connect the RED battery
wire to the POSITIVE (+) terminal. Pay close attention to

the color of the wires. If the wires are connected incorrectly,
the control board will be damaged. NEVER insert the

battery with the terminals to the left.

Step 3

Strip approximately 3/16" of insulation from each
wire of the power cable. Twist each exposed wire
tightly (there are seven [7] wires inside the power cable
sheath). Loosen sealing nut on strain relief hub at
bottom of control box. Insert power cable into control
box through strain relief. Thread approximately 6"
of the power cable into the control box and retighten
sealing nut until the power cable locks into place.

NOTE: The battery that came with your GTO/PRO® 3000 ,

MUST be placed horizontally battery with the terminals on the
RIGHT. If an optional second battery is needed, both batteries

must be placed vertically with terminals at the bottom. An
optional second battery can be used for solar and/or high traffic
applications, if needed..

Step 5

Review the Installation Overview illustration on page 12 before proceeding.

Cut a slot into the driveway to accommodate PVC conduit (not provided). The buried conduit will protect the 40 foot power
cable from automobile tires, lawn mower blades, weed eaters, and grazing animals. Pull the 40 foot second operator power
cable through the conduit and secure them into the slot in the driveway.

Step 6

Strip approximately 3/16" of insulation from
each wire of the 40 foot power cable. Twist each
exposed wire tightly. Insert the second operator
power cable upward through the right strain relief
(if necessary, loosen the sealing nut). Thread
approximately 4" of wire into the control box.
Retighten strain relief (on the black sheath of the
power cable) until the power cable locks into place.

Insert the stripped wires of the power cable into the
appropriate terminals on the SLAVE OPERATOR
terminal block. The green wire should be inserted
into the GRN terminal, the blue wire into BLU,
the orange wire into ORG, black wire into BLK,
and the red wire into the RED terminal.

Tighten the set screws against the end of the wires.

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® 300/3200® 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.

Tallahassee, FL 32303

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.

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.

Step 4

Feed the low voltage wires upward through the strain relief opening on the
lower left of the control box. Pull 6" to 8" of wire into the control box and
tighten the strain relief screw to secure the wires.

WARNING! DO NOT PLUG THE TRANSFORMER
INTO AN OUTLET DURING THIS STEP! THE
TRANSFORMER MUST ONLY BE PLUGGED INTO
AN OUTLET DURING STEP 7!!

Step 5

Strip 3/16" off the ends of the low voltage wire
and twist tightly. Attach these ends to the 18VAC
terminals located on the POWER IN terminal block
(see illustration at right). Be certain not to let the

exposed wires touch each other!

Insert one transformer wire into an 18VAC terminal.
Insert the other transformer wire into the remaining
18VAC terminal. The transformer wires can be
connected to the 18VAC terminals regardless of color.

Tighten set screws against exposed end of wires. A
dab of household petroleum jelly on each terminal will
help prevent corrosion.

Step 7

Plug the transformer into the electrical outlet.
(Use of a surge protector with the transformer is strongly
recommended.)

HINT: Keep a few mothballs in the control box to
discourage insects from entering it and damaging the
control board.

CONTROL BOARD SETTINGS

DIP Switches

Main DIP Switch Settings (MODES)

DIP Switch #1 - Soft Start/Stop

The Soft Start/Stop feature slowly starts

the gate as it begins to open and slows the
gate as it comes to the closed position. This
saves wear and tear on the gate and gate
operator system.

DIP Switch #2 - Warning Buzzer

The Warning Buzzer alerts you when the

gate operator is beginning to either open
or close the gate. It sounds for the first 2
seconds in each direction. It also sounds a
warning when the gate obstructs two times
in one cycle. Switching this to OFF only
disables the open and close warning not the
obstruction warning.

DIP Switch #3 - Auto-Close

With the Auto-Close switch in the OFF

position the gate will remain open until it
receives another signal from an activation
device such as a transmitter, keypad, or
push button control. With the Auto-Close
switch in the ON position the gate operator
will automatically close the gate, if the gate
is in it's open limit position. The time the
gate will remain open is determined using
DIP Switches #6 and #7.

DIP Switch #4 - Push/Pull-to-Open

If your gate opens into the property the

DIP Switch #5 - B2/D1 Mode

This DIP Switch must remain in the OFF

DIP Switches #6 and #7

The combination of these two switches

DIP Switch is set to OFF (factory). If your
gate opens out from the property the DIP
Switch must be set to the ON position.
NOTE: if you have a Push-to-Open gate
application you will need a Push-to-Open
bracket (see Push-to-Open Instructions on
page 30).

position unless the gate operator is going
to be used by a guard or gate attendant,
who can only open the gate when constant
pressure is applied to a push button control
device.

determines the amount of time the gate will
remain open when DIP Switch #3 is set in
the ON position.

IMPORTANT CONTROL BOARD SETTINGS:

CONTROL BOARD DIP SWITCH #1 is factory
preset in the ON position and MUST remain in the
ON position. Changing this setting can damage
your gate, gate opener and
possibly void your warranty!

TURN CONTROL BOX ON

Your GTO/PRO® 3000/3200 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

With the second 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 ON position (if the MASTER gate closed first) or the OFF position (if the SLAVE gate
closed first) then PRESS & HOLD the “SET LIMIT" button on the control board for 5 seconds.

Press the transmitter button and allow the gates to return to the fully open position. BOTH YOUR MASTER AND SLAVE
GATE’S CLOSED POSITION LIMITS ARE NOW PROGRAMMED.

TESTING YOUR CLOSED LIMIT SETTING:

Press your entry transmitter and allow your gates to close. If CLOSED positions are not correct or need to be changed, you
will need to CLEAR your CLOSED LIMIT settings and follow Steps 1-7 again.

CLEARING PROGRAMMED CLOSED LIMIT SETTING:

If you make a mistake and set the limit at the wrong position – press your transmitter to return the gates to their fully opened
positions, then press and hold the "SET LIMIT" button for 10 seconds. This will clear the memory for the closed limit

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® 3200 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.

2. Set the transmitter DIP Switches

There are nine (9) transmitter DIP switches; each can be placed in three different positions
(+, 0, –). DO NOT set all the switches in the same position, such as all +, all 0, or all
–. Once the DIP switches have been set to a personal code, replace and close the access
cover.

WARNING: No other adjustments should be made inside the transmitter.

3. “Teach” the New Code to Control Board Memory

A. Press and hold transmitter button.
B. Press and hold the LEARN TRANSMITTER button
on the control board for 5 seconds.
C. Release transmitter button.
D. Release LEARN TRANSMITTER button. The new
code is stored in control board memory.

IMPORTANT: For safety reasons the obstruction
setting or Stall Force on the Mighty Mule® control
board comes from the factory set at MIN (mini­mum). In many gate installations this setting will
need to be adjusted to overcome the weight and
size of the gates.

TThe Stall Force potentiometer on the control
board operates like a volume control on a radio. It
controls the obstruction sensitivity (or the amount
of force the opener will apply to an obstruction)
before it automatically stops and reverses direction
for approximately two (2) seconds.

Use a small slotted screwdriver to turn the arrow in
the center of the potentiometer. Adjust the sensitiv­ity from the MINIMUM position where the gate
operates without obstructing from its own weight
or the wind conditions in your area.

NOTE: You may need to increase the
stall force in cold weather due to increased
resistance from gate hinges.

ALWAYS KEEP SAFETY AT THE TOP OF YOUR LIST WHEN ADJUSTING OR

SERVICING YOUR AUTOMATIC GATE OPENER!

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.

Although GTO strongly recommends the use of additional safety devices, we do not endorse any

specific brand names. Only use products that are certified and listed to be in compliance with any

applicable UL standards (United Laboratories) and national and regional safety codes.

Call GTO Sales at 1-800-543-4283 for information on compatible

products for your specific application.

The GTO/PRO® 3000/3200 will ONLY accept accessory devices with normally open contact output.

Contact Sensors (safety edges)

If not installing a contact sensor skip to next section.

PLEASE NOTE: Contact sensors are not included with the GTO/PRO® 3000/3200.

The GTO/PRO® 3000/3200 is equipped with built-in obstruction sensitivity. The operator is designed to stop and reverse
the gate within 2 seconds when it comes in contact with an obstruction. However, obstruction sensitivity, although function­ing properly, may not be sensitive enough to prevent bodily injury in some circumstances. To augment your protection
against entrapment, GTO recommends using some form of additional safety device. When installed, contact sensors must
be mounted in compliance with UL 325, Underwriters Laboratories safety standard for gate operators. Review page 5 for
information about mounting requirements for safety edges ("contact sensors").

Refer to the sensor manufacturer’s instructions for
information about installing these devices on a vehicular
gate.

Make sure the power switch to the operator
is turned off before connecting safety device
wiring to the terminal blocks. Unplugging
the transformer does not turn power to the
operator OFF.

Contact Sensor Input Connection:

Connect one of the OPEN EDGE contact sensor wires to the

COMMON (COM) terminal and the other to the OPEN
EDGE terminal on the GTO/PRO®3000/3200 control board.

Connect one of the CLOSE EDGE contact sensor wires to the

COMMON (COM) terminal and the other to the CLOSE
EDGE terminal on the GTO/PRO® 3000/3200 control board.

Activation of a contact sensor while the gate is in motion
will cause the gate to stop and reverse within 2 seconds.

Non-Contact Sensor Connection:

Connect one of the non-contact sensor dry contact output wires to
the COMMON (COM) terminal and the other to the SAFETY
terminal on the GTO/PRO® 3000/3200 control board.

This input is ONLY monitored when the gate
is closing. Activating the non-contact sensor
(obstructing the safety beam path) will cause the
gate to reverse to the fully open position.

Shadow Loop

If not installing a shadow loop skip to next section.

PLEASE NOTE: Non-contact sensors are not included with the GTO/PRO® 3000/3200 .

Refer to the sensor manufacturer’s instructions for information
about installing these devices on a vehicular gate.

Make sure the power to the operator is turned
off before connecting safety device wiring to the
terminal blocks. Unplugging the transformer does
not turn power to the operator OFF.

Shadow Loop Connection:

Connect one of the shadow loop wires to the COMMON terminal
and the other to the SHADOW LOOP terminal on the GTO/
PRO® 3000/3200 control board.

The SHADOW LOOP is a detector located with the moving
path of the gate to prevent the gate from closing when a vehicle
in the path.

Accessory Input Connection:

Connect one of the accessory wires to the COMMON (COM)
terminal and the other to the CYCLE CLOSE terminal on the
GTO/PRO® 3000/3200 control board.

Each activation of the accessory will cause the
gate to cycle as follows:

Output Relay

The output relay provides N/O and N/C contact. N/O contact
functions only when gate is moving. N/C contact functions only
when gate is at rest. Relay can switch up to 36 volts A/C or D/C
and can be used for strobe type warning lights, to turn on safety
beams, etc.

Determining The Mounting Position
of The Post Bracket Assembly

Swinging gates shall not open into public access areas!

A "Push-to-Open" gate opens out from the property.

A Push-to-Open Bracket is required for this type of installation (see
Accessory Catalog). If you have a pull-to-open gate (gate opens into the

property), return to page 14; step 3.

In a PUSH-TO-OPEN installation the operators are installed while the gates
are in the closed position.

Step 1

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.

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.

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).

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. (Some vertical adjustment

is possible by sliding the post bracket assembly up and down.) 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.

Step 4

Make sure the control box power switch is OFF. Use a small
screwdriver to move the Number 4 DIP switch from the factory
setting (OFF / Pull-To-Open) to ON for Push-To-Open. Turn
power switch ON. The control board is now configured to push
the gate open.

Step 5

Install the second gate operator on the other gate in the same
manner. Then refer to the CONTROL BOARD SETTINGS on
page 26 for gate sequencing and other programming steps before
proceeding.

Setting the Open Position Limit

In a PUSH-TO-OPEN Installation Your GTO/PRO® 3200 has two Limit Settings

1) CLOSED Limit setting: (Gates in the CLOSED POSITION / FACTORY SET NOT ADJUSTABLE) The closed limit
setting in the closed position.

2) OPEN Limit setting: (Gates in the OPEN POSITION) To achieve optimum open 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 CLOSED POSITIONS.

Step 2

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

Step 3

• IF the MASTER gate was the first gate to reach the opened position: set the number 4 DIP switch of the DUAL MODES
switches on the control board to the OFF position. Then press and hold the SET LIMIT button for five seconds.

• IF the SLAVE gate was the first gate to reach the opened position: set the number 4 DIP switch of the DUAL MODES
switches to the ON position. Then press and hold the SET LIMIT button for five seconds.

Step 4

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

Step 5

Activate your openers again by pressing the entry transmitter button. Your
gates should now be moving from the closed positions toward their open
positions. The first gate will stop at the spot you just programmed and the
second gate will continue to open until you press the transmitter button again.
Press the transmitter button when the second gate reaches the desired open
position. This step may be repeated until desired open position is achieved.
Once the desired OPEN position has been achieved, proceed to step 6.

Step 6

• IF the MASTER gate was the second gate to reach the opened position: set
the number 4 DIP switch of the DUAL MODES switches on the control
board to the OFF position. Then press and hold the SET LIMIT button for
five seconds.

• IF the SLAVE gate was the second gate to reach the opened position: set
the number 4 DIP switch of the DUAL MODES switches to the ON position. Then press and hold the SET LIMIT button
for five seconds.

Step 7

Press the transmitter button and allow the gates to return to the closed position. BOTH YOUR MASTER AND SLAVE
GATE’S OPEN POSITION LIMITS ARE NOW PROGRAMMED.

TESTING YOUR OPEN LIMIT SETTING:

Press your entry transmitter and allow your gates to open. If OPEN positions are not correct or need to be changed, you will
need to CLEAR your OPEN LIMIT settings and follow steps one (1) to seven (7) again.

CLEARING THE PROGRAMMED OPEN LIMIT SETTING:

If you make a mistake and set the limit at the wrong position – press your transmitter to return the gates to their closed
positions, then press and hold the "SET LIMIT" button for 10 seconds. This will clear the memory for the open limit
positions. Follow steps one (1) to seven (7) again.

35

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 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.

36

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.

3. Check the position of the stroke adjustment knob.

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.

3. Check the position of the stroke adjustment knob.

IF THIS OPERATOR WILL BE USED WITH GATES THAT ARE MOUNTED ON

MASONRY, BRICK, OR ROCK (etc.) COLUMNS:

A. The simplest solution is to install the operator in a push-to-open configuration (requires Push-To-Open Bracket,

see Accessory Catalog). 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.

B. 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.

C. 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!

Solar Panel (FM123), (FM122)

The Solar Panel is a 10 watt solar powered battery charger for use with the all GTO/PRO DC gate
operator systems. Particularly suited for remote installations, each Solar Panel comes with tubular
steel support, mounting clips, wire connectors, and 8 ft. of low voltage wire (see Low Voltage Wire
