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 a pull-to-open leaf gates (gates that open
into the property). By purchasing an accessory bracket, the GTO/PRO® 4000/4200 Operators can accommodate
push-to-open gates (gates that open out from the property). 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 [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.

iii

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.

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.

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.

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

2. 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.

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 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.

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 opener.

5. 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.

6. 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.

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® web site (www.gtopro.com), by

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.

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
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.

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.

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.

13

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

/2" 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, lockwasher and nut.

mount. Align the hole in rear mount, bushing and
post pivot brackets and secure with the clevis pin
and hair pin clip.

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.

Large Bushing Goes
Under Rear Mount

Step 6:

Place a small bushing under the the front mount and
attach the gate bracket to the front mount using the
clevis pin and hairpin clip.

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.

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

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.

15

Gate in the
OPENED POSITION

2" minimum

Step 8:

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 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.

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.

17

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.

Step 1

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).

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.

Mounting the Control Box

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® 4000/4200,
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..

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

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.

Winter Ratings Zone 1 Zone 2 Zone 3
12 v dual gate (15 watts) solar charger 3 6 10

12 v dual gate (20 watts) solar charger 4 8 13
12 v dual gate (25 watts) solar charger 5 10 16
12 v dual gate (30 watts) solar charger 6 12 19

NOTE: A minimum of 15 watts of solar
charging power is required for GTO/PRO
4000/4200 dual gate systems, with a
maximum of 30 watts. An optional second
battery can be used for solar and/or high
traffic applications, if needed. Consult

Solar Panel Installation Instructions for
further information.

ON/OFF Switch

Step 1

Make sure the power switch is OFF before proceeding to the next step.

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

RED

BLACK

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!!

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.

1 2 3 4 5 6 7

ON

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 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-to­Open Instructions on page 32).

DIP Switch #5 - B2/D1 Mode

This DIP Switch must remain in the OFF
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.

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

IMPORTANT: For safety reasons the obstruction
setting or Stall Force on the GTO/PRO 4000
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.

FCC Regulation

This device complies with FCC rules Part 15. Operation is subject to the following
conditions:

1. This device may not cause harmful interference.

2. This device must accept an interference that may cause undesired operation.

Transmitter distance may vary due to circumstances beyond our control. NOTE: The

manufacturer is not responsible for any radio or TV interference caused by
unauthorized modifications to this equipment. Such modifications could void the
user’s authority to operate the equipment.

29

• 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.

Connecting Additional Safety Devices

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® 4000 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® 4000.

The GTO/PRO® 4000 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® 4000 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® 4000 control
board.

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

Push to Open Installation

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 PRO-SW4000 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 13.

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

1/2" Washer

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.

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).

33

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
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 Guide

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.

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 (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!
