E-Z GATE OPENERS

PLEASE READ THIS FIRST!

Thank you for purchasing a Mighty Mule® 352 E-Z Gate Opener—GTO's "do-it-yourself" automatic gate opener! When correctly installed and properly used, your Mighty Mule® 352 E-Z Gate Opener will give you many years of reliable service. Please read the following information and watch the enclosed video to ensure you have the correct system for your particular needs. Furthermore, this manual and the video will enable you to properly install your Mighty Mule® 352 E-Z Gate Opener.

The

Mighty Mule® 352 E-Z Gate Opener

is designed for installation on a

pull-to-open dual gate leafs

(gates that open into the property). By purchasing an accessory bracket (FM148), the Mighty Mule®

352 E-Z Gate Opener can accommodate a push-to-open dual gate leafs (gates that open out from the property). The gates must not exceed 8 feet and 550 pounds or exceed 16 feet and 150 pounds (please

see Technical Specifications on page 10). The Mighty Mule® 352 EZ Gate Opener can be used on vinyl, aluminum, chain link, farm tube, and wrought iron gates.

Use on solid (surface) gates is not recommended. Solid surface gates have a high resistance to the wind. If the wind is strong enough, the opener will obstruct

and stop, blow fuses, or may damage the equipment.

The Mighty Mule® 352 E-Z Gate Opener accommodates extra transmitters, digital keypads, solar panels, push buttons, automatic gate locks, and other access control products. These optional accessories (see

the enclosed Mighty Mule® Accessory Catalog) are available at most stores. Your store should be able to special order any accessory not in stock. If your store cannot special order accessories, please call the

GTO Sales Department (800-543-GATE).

The Mighty Mule® 352 E-Z Gate Opener 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 Mighty Mule® 352 E-Z Gate Opener 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 NOTE—If your application requires any of the following:

Slide gates;

Heavy duty or commercial uses;

Professional installation; please call GTO at (800) 543-GATE [4283] or (850) 575-0176 for information about our GTO/PRO professional line of gate openers 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 OPENER: watch the enclosed video and read these instructions carefully and completely

to become familiar with all parts and installation steps. The video is only designed as an overview of the installation procedure. You must read the installation manual for detailed instructions on gate opener safety and proper use of the gate opener.

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 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 opener is removed from the gate. ONLY disconnect the opener when the opener power switch is OFF and the gate is NOT moving.

Disconnecting the Opener

1. Turn opener power switch OFF.

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

3. Remove the opener from the mount.

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

Front Mount

Clevis Pin

Gate Bracket

IMPORTANT:

NEVER allow opener arm to hang by the front mount - it will break from the arm weight.

Bushing

CAUTION:

Because the Mighty Mule gate opener is battery powered, disconnect the opener

ONLY when the power switch on the opener is turned OFF. Unplugging the transformer does not turn power to the opener OFF.

Hairpin Clip

NOTE: Substitute a Pin Lock (FM133) for the clevis pin on the front mount only of the 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. 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 opener installation

must comply with any applicable local codes.

I. Before Installation

1. Verify this opener 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 opener 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 opener for manual gate operation (see page 1).

4. This gate opener 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.

IMPORTANT SAFETY INSTRUCTIONS

Entrapment Zones for a proper Pull-To-Open installation:

Zone 1 – leading edge of the master and second gate.

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.

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 auto matic 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 an activated 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 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. Grease hinges, spray push pull tube with high quality silicone spray.

7. 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 Service Department.

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

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

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

11.

IMPORTANT: Save these safety instructions. Make sure everyone who is using or will be around the gate and gate opener are aware of the dangers associated with automated gates. In the event you sell the property with the gate opener or sell the gate opener, provide a copy of these safety instructions to the new owner.

Additional copies of this manual can be obtained by downloading one from the Mighty Mule® web site (www.mightymule.com), by contacting GTO, Inc., at 3121 Hartsfield Road, Tallahassee, Florida

IMPORTANT SAFETY INSTRUCTIONS

Secondary Means of Protection Against

Entrapment

As specified by Gate Opener 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 Mighty Mule® 352 utilizes Type A, an inherent (i.e., built-in) entrapment sensing system as the primary type of entrapment protection. Also, the

Mighty Mule® has provisions for the connection of Type B2 protection to be used as the secondary type of entrapment protection.

1. For gate openers 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.

Leading Edge Contact Sensor on both sides of the gate

Vehicular Gate

Post Edge Contact Sensor on both sides of the gate

Bottom Edge Contact Sensor on both sides of the gate

Vehicular Gate

Post Edge Contact Sensor on both sides of the gate

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

The Mighty Mule® 352 Gate Opener 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 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.

Preparation of the Gate

Step 1

The gate must be plumb, level, and swing freely on its hinges. Wheels must not be attached to the gate. The gate must move throughout its 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 post must be secured in the ground with concrete so it will minimize twist or flex when the opener is activated. We recommend you position the opener near the

centerline

of the gate to keep the gate from twisting and flexing and to avoid backsplash from rainwater.

The addition of a

horizontal or vertical cross

member (if one is not already in place) to provide a stable area for mounting the gate bracket 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 (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.

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

After verifying 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.

Powering Options: Transformer or Solar

IMPORTANT:

• The Mighty Mule 352 is designed and intended for use with a 12 Volt automotive or marine type battery. The battery must be placed inside a weatherproof case and located within 6 feet of the opener arm. The 10 foot harness supplied connects the battery to the master arm.

• The battery charge is maintained by the 18 Volt transformer included panel(s). The transformer

or or

by using optional solar

solar panel is connected to the opener arm control board using low voltage, 16 gauge, dual conductor, multi-stranded, direct burial wire (RB509) (see page 24

and the Accessory Catalog).

• All low voltage wire used with the Mighty Mule® 352 Gate Opener must be 16 gauge dual conductor, multi-stranded, direct burial wire (see page 24 and the Accessory Catalog).

Do not run more than 1000 feet of wire.

• 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.

• If your gate is more than 1000 ft. from an ac power source, you will need to use at least one

10 watt Solar Panel to charge the battery (see Accessory Catalog). Refer to the

Solar Panels

and Gate Activity chart below.

NEVER USE TRANSFORMER AND SOLAR PANEL(S) AT THE SAME TIME

– it will damage the control board –

Solar Panel and Gate Activity Chart

The table and map illustrate the maximum number of gate cycles to expect per day in a particular area when using from 10 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 and will require additional solar panels.

* Use up to 250 feet of 16 AWG wire to place solar panel in a good location.

Connecting the Transformer

IMPORTANT: Never connect the transformer and a solar panel to the opener control board at the same time. It will damage the control board.

If you are using SOLAR PANEL(S) to charge the opener battery, skip this section and go to "Connecting

Solar Panel(s)" section on page 26.

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 1

Select the 120 Volt electrical outlet into which you will plug the transformer. Lay the 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 mowers, weed eaters, and grazing animals. Be sure to bury the wire laid in the trench.

Step 2

Bring enough wire up through the PVC conduit to allow for gate movement from open to closed position. See example right.

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 coil excess cable or store it in the control box.

DO NOT run cable in conduit containing ac wiring.

The receiver range can vary from 50 to 100 feet depending upon weather, topography, and external interference.

NOTE: Do not mount upside down.

Final Step

When everything has been connected to the opener...

Replace the control board access cover. If you were working with the opener with the control board access facing up, remove the opener arm from both mounts and remount it in the upright position (control board cover facing down). Failure to remount opener in the up right position will allow water to enter the opener and cause damage to the opener control board.

Push to Open Installation

Determining The Mounting Position of The Post Bracket Assembly

Swinging gates shall not open into public access areas!

"Push-to-Open" gates open out from the property.

Push-to-Open Brackets are required for this type of

installation (see Accessory Catalog). If you have pull-to-open gates (gate opens into the property), return to page 13; step 3.

In a PUSH-TO-OPEN installation the opener is installed while the gate is in the closed position.

Step 1

With the gate in the closed position (up to 110º from its open position), and the opener fully retracted, adjust the post bracket assembly and gate bracket until the opener is level. While holding the opener 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 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.

Column Installation Information

I

F THIS OPENER 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 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. 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 opener and power cable. This job is NOT for the inexperienced!
