PLEASE READ THIS FIRST!  
Thank you for purchasing a GTO/PRO-SW2502 When correctly installed and properly used, your GTO/PRO-  
SW2502 Operator 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-  
SW2502 Automatic Gate Operator.  
The GTO/PRO-SW2502 Operator is designed for installation on pull-to-open gates (gates that open into the  
property). By purchasing an accessory bracket, the GTO/PRO-SW2502 Operator can accommodate push-to-open  
gates (gates that open out from the property). The gates must not exceed 16 feet in length (per leaf) nor weigh more  
than 500 pounds (per leaf) (please see Technical Specifications on page 10). The GTO/PRO-SW2502 Operator  
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-SW2502 Operator accommodates 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-SW2502 Operator features adjustable obstruction sensing. This safety feature makes the gate  
stop and reverse direction within 2 seconds when it comes in contact with an obstruction. MIN is the factory setting;  
meaning the gate will exert the minimum force on an obstruction before it stops and reverses direction.  
The GTO/PRO-SW2502 Operator also has an adjustable auto-close feature. After the gate reaches the fully open  
position, it can be set to remain open up to 120 seconds before automatically closing. Pressing the transmitter button  
at any time after the gate opens fully will cause it to close immediately. OFF is the factory setting; meaning the gate  
will stay open until you press the transmitter (or keypad, etc.) again.  
Please call GTO/PRO 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.

IMPORTANT SAFETY INSTRUCTIONS  
Because automatic gate openers produce high levels of force, consumers need to know the potential hazards associated with  
improperly designed, installed, and maintained automated gate opener systems. Keep in mind that the gate opener 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 opener, 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 opener or its components, serious injury, or death.  
Because GTO/PRO automatic gate openers 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 operator power  
switch is OFF and the gate is NOT moving.  
Front or Rear Mount  
Disconnecting the operator  
1. Turn operator power switch OFF.  
2. Remove hairpin clip, clevis pin, and bushing  
Clevis Pin  
from the front mounting point.  
3. Remove the operator from the mount.  
The gate can be opened and closed manually  
when the operator is disconnected.  
Gate Bracket  
IMPORTANT: NEVER allow operator arm to hang by  
the front mount - it will break from the arm weight.  
Bushing  
CAUTION: Because the GTO/PRO gate operator is  
battery powered, disconnect the operator ONLY when the  
power switch on the operator is turned OFF. Unplugging  
the transformer does not turn power to the operator OFF.  
Hairpin Clip  
NOTE: Substitute a Pin Lock for the clevis pin on the front  
mount of each gate opener to prevent unauthorized removal of  
the opener from the gate (see Accessory Catalog).

IMPORTANT SAFETY INSTRUCTIONS  
For The Consumer  
WARNING: To reduce the risk of injury or death:  
1.  
2.  
3.  
4.  
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 opener installation must comply with any applicable local codes.  
I. Before Installation  
1.  
2.  
Verify this dual opener is proper for the type and size of gate, its frequency of use and the proper class rating.  
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 opener and safety devices used with the system.  
3.  
4.  
5.  
6.  
Review the operation of the system to become familiar with its safety features. Understand how to disconnect the  
opener for manual gate operation (see page 1).  
This gate opener 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.  
2.  
3.  
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.  
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.  
6.  
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/PRO 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.  
4.  
5.  
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.  
6.  
KEEP GATES PROPERLY MAINTAINED. Always turn power to opener 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.  
8.  
Service the gate and gate opener regularly. Grease hinges, and replace the battery every 3-5 years.  
To operate this equipment safely, YOU must know how to disconnect the opener for manual gate operation  
(see page 1). If you have read the instructions and still do not understand how to disconnect the opener, contact the  
GTO/PRO Service Department.

IMPORTANT SAFETY INSTRUCTIONS  
Secondary Means of Protection Against  
Entrapment  
As specified by Gate Operator Safety Standard, UL 325 (30A.1.1), automatic gate openers 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 utilizes Type A, an inherent (i.e., built-in) entrapment sensing system as the primary type  
of entrapment protection. Also, the GTO/PRO 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 opener is not subjected to mechanical damage.  
C. A wireless contact sensor such as one that transmits radio frequency (RF) signals to the gate opener 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 gate operator is designed to stop and reverse within 2 seconds when the gate comes in contact with  
an obstruction. Additionally, these openers 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 opener  
receives an intended signal from a hard wired 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.

Installation Overview  
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  
openers on a masonry column requires special procedures; see Column Installation Information on page 38 if you intend  
to mount the openers 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 32  
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.  
Horizontal Cross Member  
Step 2  
The fence posts must be secured in the ground with  
concrete so they will minimize twist or flex when the  
openers are activated. We recommend you position the  
openers 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.

Installation of Mounting Hardware  
The position of the post bracket determines the leverage and efficiency of the opener. The post bracket position also sets the  
clearance between the opener and gate in the open and closed positions (minimum 2 inches for safety reasons).  
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 opener, bolts that completely penetrate the fence post must be used.  
On wooden posts, place a metal plate or washer  
Metal Plate  
Metal Plate  
Wooden Post

(not supplied) between the nuts and the fence  
post to prevent the thrust of the opener 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  
opener is moving the gate.

Pull-to-Open Installation  
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 opener and gate when the opener is installed.

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 opener in both the open and closed positions, as shown in the  
diagrams below. This clearance will give the opener 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 opener, swing the gate and gate opener to the closed position. With the gate and gate  
opener in the closed position check the clearance and be sure that the gate opener is not binding at the post pivot bracket.  
If you don't have 2 inches of clearance or the gate opener 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 opener to the gate  
bracket in the open position and recheck the gate opener level and make sure the brackets are clamped securely.

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.  
Use mounting  
holes and screws  
provided to mount  
control box to a  
secure surface.  
NOTE: The battery that came with your GTO/PRO,  
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

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 Gate Opener must be 16 gauge dual conductor,  
multi-stranded, direct burial wire (see page 22 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 at least one 5 watt  
Solar Panel to charge the battery (see Accessory Catalog). Refer to the Solar Panels and Gate  
Activity chart below.

NOTE: A maximum of 30 watts of solar  
charging power can be connected to the  
GTO/PRO Gate Opener. Consult Solar  
Panel Installation Instructions for further  
information.  
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.

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 opener system. Telephone wire and solid core wire do not deliver  
enough voltage for your gate opener 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
the selected electrical outlet to the control box. Wires coming up from th
ground should be run through PVC conduit to protect them from lawn mo
blades, weed eaters, and grazing animals. Be sure to bury the wire laid in
trench.  
Step 4  
Feed the low voltage wires upward through the strain relief opening on th
lower left of the control box. Pull 6" to 8" of wire into the control box an
tighten the strain relief screw to secure the wires.

Setting the Closed Position Limits  
TURN CONTROL BOX ON  
Your GTO/PRO 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 openers 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 that reaches the desired closed position first by pressing the  
entry transmitter button again. 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 gate that closed first 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 openers 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.

Step 7  
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  
positions. Follow Steps 1-7 again.  
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 Gate Opener®. 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  
On the back of the transmitter use a small phillips head screw driver to remove  
the two screws on the sides of the visor clip and separate the front cover from the  
LE  
D
transmitter. With the front cover removed, the battery and the DIP switches will  
be exposed. To set a new code, use a small screwdriver to move the switches.

Obstruction Sensitivity Potentiometer  
IMPORTANT: For safety reasons the obstruction setting or Stall  
Force on the GTO/PRO control board comes from th
MIN (minimum). In many gate installations this sett
be adjusted to overcome the weight and size of the g
TThe Stall Force potentiometer on the control board
volume control on a radio. It controls the obstruction
the amount of force the opener will apply to an obstr
automatically stops and reverses direction for approx
seconds.  
STALL FORCE  
Use a small slotted screwdriver to turn the arrow  
in the center of the potentiometer. Adjust the sen-  
sitivity 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 SAFETYAT 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.

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 SW2502.  
The GTO/PRO SW2502 is equipped with built-in obstruction sensitivity. The opener 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 openers. Review page 5 for infor-  
mation about mounting requirements for safety edges ("contact sensors").

Maintenance  
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.

Troubleshooting Guide  
If your gate opener does not function properly after it is installed, use this guide before calling the GTO/  
PRO Service Department.  
Audible Alarm Indications  
Symptom  
1) Gives one short beep and no operations when you press the remote.  
2) Gives a three second tone, 1 second of silence, and then another three second tone repeatedly.  
3) Gives a constant tone.  
Diagnosis  
1) There is a power problem with the Mighty Mule 500/502, PRO-SW2500/2502, PRO-SW3000/3200 and PRO-  
SW4000/4200.  
-
-
The battery could have a dead cell in it.  
The battery could be low. Disconnect the transformer or solar panel and check the battery voltage. If the  
battery is fully charged, the voltage should be between 12.5 vdc to 13.5 vdc. Any voltage reading below  
12vdc is low.  
-
The battery could be dead or disconnected at battery or board. The transformer or solar panel is powering  
the board with the charge voltage. Disconnect the transformer or solar panel to see if the board still  
powers up.  
-
The fuse is blown. Replace the fuse.  
2) On the Mighty Mule 500/502, PRO-SW2500/2502, PRO-SW3000/3200 and PRO-SW4000/4200, the board  
is giving a limit switch error. Check the connections on the power cable. If this does not work, check the  
terminal voltages on the circuit board that is supplied to the limit switch. The voltage across the orange and  
green and the brown and green should be 5 vdc without the arm connected. If the board is good, the arm will  
need repair.  
3) Mighty Mule 500/502, PRO-SW2500/2502, PRO-SW3000/3200 and PRO-SW4000/4200  
-
The battery could be very low at about 10 vdc. Flip the power switch off and back on to see if it will clear  
the alarm. If the alarm is not cleared, check to make sure that there is power at the outlet. There could be  
a tripped breaker or GFI. The transformer could be unplugged. The transformer could be blown. If there  
is no charge power from the transformer, the green light will be off.  
-
The board has sensed an obstruction two times in a row. If the alarm clears by switching the power off  
and on, the board is sensing an obstruction.  
o
Something on or about the gate is causing the arm to push too hard to open or close the gate. Look  
for something in the path of the gate or something unlevel, out of plumb, or that is binding or  
pinching.  
o
o
This can be due to a low battery when the unit is charged with a solar panel. Test the charging circuit  
and the solar panel in direct sunlight.  
If the alarm will clear by switching the power off and on, the board is sensing an obstruction.  
Disconnect the arm from the gate. If it is still obstructing, increase the Stall Force. Max it out if you  
have to. However, do not leave the Stall Force at this setting when connected to the gate. If the arm  
is in the middle of its cycle, it extends a couple of inches, retracts a couple of inches, and the tube  
does not hit the limit switch when retracted, the rev counter in the arm is bad.

Diagnostic LEDs  
Status (Clear LED)  
1) The Status LED blinks once whenever there is a change in any of the control inputs. This includes  
changes to any of the seven position DIP switches on the board, the Set Limit Button or the Learn  
Transmitter button is pressed, the limit switch in the arm is activated, or any of the six accessory inputs  
(cycle/close, safety, exit/open, etc.) are used.  
2) The Status LED flashes when the board learns a new limit.  
3) Use these lights to determine if the circuit board is receiving inputs from the control inputs or the  
accessories.  
RF (Yellow LED)  
1) The RF LED flickers whenever the antenna receiver receives a radio frequency in the 318 MHz range.  
2) The RF LED flickers when the remote transmitter or the wireless keypad is activated.  
3) Electronic noise that produces a 318 MHz signal will cause the RF LED to flicker. An electric motor  
running is one example.  
4) When the RF LED flickers, the receiver chip (U8) and the antenna receiver are working properly.  
AC Power (Green LED)  
1) The AC Power LED stays on whenever the transformer is putting out voltage to the circuit board. If the AC  
Power LED is off, there is no power from the transformer.  
2) The AC Power LED does not come on when the battery is charged by solar panel without the transformer or  
when the transformer is unplugged.  
Red LED  
1) The Red LED comes on whenever the battery is fully charged. Any time power is drained from the  
battery to operate the gate; the light goes off until the battery is fully charged again. Under normal  
operations, the light will cycle on and off indicating the charging circuit is keeping the battery charged.  
2) If the AC Power LED is on and:  
1. Éthe Red LED is on and the unit is not working.  
a. The fuse could be blown. The unit will give one short beep when the remote is  
pressed or when an accessory is used.  
b. The battery is not connected or there is a loose connection. Check the wires  
that connect to the battery and where they connect to the circuit board from the  
battery. The unit will give one short beep when the remote is pressed or when an  
accessory is used.  
c. The battery is no longer taking a charge. The battery could have a dead cell.  
Unplug the transformer and check the voltage on the battery under a load (try to  
operate the gate opener). If the voltage drops more than 1 vdc, the battery has a  
dead cell. The unit will give one short beep when the remote is pressed or when  
an accessory is used.  
2. ...the Red LED is off.  
a. The battery is charging if the unit is working. The battery voltage should increase  
until it gets to 14.5 vdc.  
b. The battery may be low if the unit is not working. Unplug the battery and check  
the voltage. The battery should have 12.5 to 13.5 vdc. Any voltage reading  
below 12 vdc is a little low and could cause intermittent or no operations.

3) If the AC Power LED is off and:  
1. Éthe Red LED is on and the unit is not working.  
a. If the unit is charging with solar in adequate sunlight, the battery is not connected  
or there is a loose connection. Check the wires that connect to the battery and  
where they connect to the circuit board from the battery. The unit will give one  
short beep when the remote is pressed or when an accessory is used.  
b. The battery is no longer taking a charge. The battery could have a dead cell.  
Disconnect the solar panel and check the voltage on the battery under a load (try  
to operate the gate opener). If the voltage drops more than 1 vdc, the battery  
has a dead cell. The unit will give one short beep when the remote is pressed or  
when an accessory is used.  
c. The fuse could be blown if the battery is being charged by solar panel. The unit  
will give one short beep when the remote is pressed or when an accessory is used.  
2. Éthe Red LED is off.  
a. If the unit is working, the battery is charged by a solar panel, and there is  
adequate sunlight, the battery is charging.  
b. If the unit is not working, the battery may be low. Disconnect the battery and  
check to see if there is over 12 vdc on the battery. If not, charge the battery with a  
trickle charger at 12 vdc 2 adc for three to four hours.  
c. If the unit is not working, the fuse could be blown. The unit will give one short  
beep when the remote is pressed or when an accessory is used.  
d. If the unit is not working, the battery is not connected or there is a loose  
connection. Check the wires that connect to the battery and where they connect  
to the circuit board from the battery. The unit will give one short beep when the  
remote is pressed or when an accessory is used.

The simplest solution is to install the opener 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 opener 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 opener mounting brackets and masonry surface for  
additional strength.  
B.  
C.  
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 opener and power cable. This  
job is NOT for the inexperienced!

ACCESSORIES  
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  
for additional wire). The GTO/PRO® control board has clearly labeled terminal connections for easy  
installation of the Solar Panel. Installation in some regions of the world will require multiple solar  
panels for adequate charging power. Solar Panel (FM122) is a 5 watt solar powered battery  
charger with all the same features as (FM123).  
Push Button Control (RB101)  
Unlit doorbell button for remote entry or exit control. Wires directly to the control board and uses 16  
gauge multi-stranded, dual conductor low voltage wire (sold separately).  
Pin Lock (FM345)  
The Pin Lock substitutes for the clevis pin at the front end of the GTO/PRO® 1500 gate operator.  
Helps prevent theft of the operator from the gate, while allowing quick release of the operator.  
Key Chain Mini Transmitter (RB744)  
The Key Chain Mini Transmitter is a miniature version of the GTO/PRO® entry transmitter and has  
the same adjustable code settings. 12 Volt battery included.  
Entry Transmitter (RB741)  
The GTO/PRO® entry transmitter, with adjustable code settings, is standard equipment with all  
GTO/PRO® systems. 9 Volt battery included.  
Digital Keypad (F300)  
The specially designed digital keypad can be easily installed as a wireless or wired keypad. It can be  
programmed to use up to fifteen different personal identification number (PIN) codes. Each code is  
face programmable with additional security features built in. Wired installations require 16 gauge, low  
voltage, multi-stranded, dual conductor, direct burial wire (sold separately). Requires 3 AA batteries
