E-Z GATE OPENER

PLEASE READ THIS FIRST!

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

Gate Opener®.

The Mighty Mule Gate Opener® is designed for installation on a pull-to-open dual leaf gate (gates that open into the property). Using an accessory kit, the Mighty Mule Gate Opener® can accommodate a push-to-open dual leaf gate (gates that open out from the property). The gate must not exceed 16 feet in length nor weigh more than 350 pounds (please see Technical Specifications on page 10). The Mighty Mule Gate Opener® 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 opener will obstruct and stop.

The Mighty Mule 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.

The Mighty Mule Gate Opener® features adjustable obstruction sensing. This safety feature makes the gate stop and reverse direction for 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 Gate Opener® also has an adjustable auto-close feature. After the gate reaches the fully open position, it can be set to remain open for 1 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:

Swing gates longer than 16 feet or weighing more than 350 pounds; 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 videotape and read these instructions carefully and completely

to become familiar with all parts and installation steps.

IMPORTANT SAFETY INSTRUCTIONS

Clevis Pin

Hairpin Clip

Washer

Gate Bracket

Front Mount

Because automatic gate openers produce high levels of force, consumers need to know the potential hazards associated with improperly designed, installed, and maintained 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:

Disconnecting the Openers

1. Turn control box power switch OFF.

2. Remove hairpin clip, clevis pin, and washer from front mount.

3. Pull front mount away from gate bracket.

Repeat steps 1 – 3 for the second opener

Your dual gate can be opened and closed manually when the openers are disconnected.

NOTE: Substitute Pin Locks for the clevis

pins to prevent unauthorized removal of the openers from the gate (see Accessory

catalog).

CAUTION: Disconnect the openers ONLY when the control box power switch is OFF and the gate is NOT moving.

IMPORTANT SAFETY INSTRUCTIONS

For The Consumer

WARNING: To reduce the risk of injury or death:

1. READ AND FOLLOW ALL INSTRUCTIONS. Failure to meet the requirements set forth in the instruction

manual could cause severe injury and/or death, for which the manufacturer cannot be held responsible.

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.

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 safety edges and photo beams provide additional protection against entrapment (see page 5).

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 opener OFF before preforming 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 opener regularly. Grease hinges, spray push pull tube with high quality silicon spray and replace the battery every two (2) years.

8. 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.

9. Disconnect the opener 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 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.

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 provisions for, or be supplied with, at least one independent primary and one independent secondary means to protect against entrapment. The

Mighty Mule 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, 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.

Installation Overview

Pull-to-Open Dual Gate (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 gate. Mounting the openers on masonry columns requires special procedures; see Column Installation Information on page 37 if you intend to mount the openers on columns. Furthermore, if you have a push-to-open dual gate, 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 Leaves

Step 1

The gate leaves must be plumb, level, and swing freely on their 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 gate leaves weighing over 250 lb. should have ball bearing hinges with grease fittings.

Step 2

The fence posts must be secured in the ground with concrete so they will not twist or flex when the openers are activated. Be sure to position the openers near the centerline of the gate to keep the gate from twisting and flexing. 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.

Horizontal Cross Member

Vertical Cross Member

Page 16

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.

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.

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

IMPORTANT:

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

Because the size tube gates vary, it is impossible to provide the appropriate reinforcement material for every application. If you are unable to locate suitable reinforcement materials, call GTO sales at 1-800-543-4283.

Determining the Mounting Position of the Post Bracket Assembly and the Gate Bracket

Step 3

Insert the 3/8" x 2" bolt through the center hole of the post brackets and post pivot bracket as shown. Fasten a

/8" washer, lock washer and nut on the end of the bolt. DO NOT overtighten the nut because the post pivot bracket will have to be adjusted later.

Step 6

Study the 4 1/2" x 4 1/2" setback template (see insert) provided with this manual. Once you are familiar with its illustrations, cut and save the template from the insert. The template will determine the correct position of the post pivot bracket before mounting the opener on the fence post.

Remove hairpin, clevis pin, and washer from front mount and close the gate. Rest disconnected opener on cross member of gate. Stand inside property next to fence post and place one end of template over center of gate hinge. Place the other end of template over the post pivot bracket hole (either of the two mounting holes in post pivot bracket can be used) where the

opener will be attached. Be sure to hold the template at a 90º angle between these two points and measure 4

/2" back from

the center of the gate hinge. You will need to rotate the post pivot bracket or the entire post bracket assembly to align it with the square angle of the template. THE ANGLE BETWEEN THE GATE HINGE AND THE POST PIVOT BRACKET

MUST MATCH THE ANGLE OF THE SETBACK TEMPLATE.

NOTE: If you move the post pivot bracket, be sure one of the post bracket holes is aligned

with the rest of the assembly (the center hole should already have a bolt through it).

The post pivot bracket can be flipped over to give more position options.

After verifying that you have complied with the 4 1/2" x 4 1/2" setback, insert the 5/16" x 1 3/4" bolt through the aligned holes of the post bracket and post pivot bracket (illustrated below) and fasten it with the 5/16" washer and nut. IMPORTANT: If you loosened the clamp on the post bracket to achieve the 4

/2" x 4 1/2" setback, 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).

Mounting the Second Opener

Step 12

Mount the second opener on the remaining gate leaf by repeating Step 3 through Step 11, starting on page 13. After you have mounted the second opener, proceed to Step 13 on the next page.

Page 21

Installation of the Positive Stops

The Mighty Mule Gate Opener® firmly holds the gate in the open and closed positions against the positive stops. The positive stops form the boundaries of the gate operating arc and help stabilize the gate leaves. Furthermore, stable gate leaves help to maintain the long life of your automatic gate opener system. To further enhance stability and security, we strongly recommended using an optional Mighty Mule Automatic Gate Lock Catalog) with your dual gate.

IMPORTANT: You need to determine which side of the driveway you will mount the control box. From this point on

the gate and gate opener on the same side as the control box will be refered to as the MASTER or FIRST gate and gate opener. The gate and gate opener on the opposite side of the driveway from the control box will be refered to as the SLAVE or SECOND gate and gate opener.

Step 13

Open position stops are required for both gate leaves (see illustration at right).

With the gate leaf at its maximum open position, measure the distance from the gate hinge to the end of the leaf.

At approximately 2/3 of this distance (using the hinge as your starting point), place a mark on the ground directly under the gate leaf. Install the open position stop at this mark (see illustration). The open position stop post may be made of wood, metal, or concrete and should be firmly secured in the ground (we recommend setting it in concrete). When the open position stop post is in the ideal position, the gate leaf will strike the post just as the opener motor shuts down. Repeat this step for the

other gate leaf.

Step 14

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

Remove hairpin clip, clevis pin, and washer from front mount and close the gate leaf (remember to support opener). The stop plate needs to be positioned near the end of the gate as shown in Illustration A. Position this closed position stop plate

vertically and fasten it to the inside bottom (i.e., SLAVE opener side) of the gate frame, but do not tighten it 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.

Step 15

Install a low profile ground stop (not provided) beneath the SLAVE gate stop plate.

The low profile ground stop may be made of metal or concrete and should be firmly secured in the ground (we recommend setting it in concrete). You must slide the closed position stop plate toward the ground

stop until they touch (see Illustration B at right and the overview illustration on page 18). Once you

have moved the stop plate to the correct position, tighten its hardware completely.

Remove hairpin, clevis pin, and washer from front mount and close the gate leaf. Fasten this closed position stop plate (horizontally) to the end of the gate frame on the gate centerline, but do not tighten it completely. Slide the stop plate toward the frame of the SECOND gate leaf until they touch (see illustration at right). Once you have moved the stop plate to the

correct position, tighten its hardware completely.

Use the appropriate hardware for your type of gate (use U-bolts if you have a tube or chain link gate; wood or lag screws for wood gates; etc.). This hardware is not provided.

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

Check List

• The gate leaves are plumb, level, and swing smoothly on their hinges.

• After measuring with the 4 1/2" x 4 1/2" setback template, the post bracket assemblies were bolted to the fence posts.

• Plates or other supports were added for the gate brackets (if necessary).

• The openers are level and mounted on the centerline of the gate.

DO NOT connect the power cables during this step. Before you connect the power cables to the openers, the control board must be set to accommodate your dual gate application. Read the DIP Switch Settings section on page 22.

Mounting the Receiver

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.

• DO NOT overtighten the mounting screws; the receiver housing could be warped and the weather seal damaged.

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

DIP Switch Settings for Dual Gates

PWR. SW.

–

Step 26

The four control board DIP switches match the openers with the type of gate on which they are installed. For example, a dual gate may pull-to-open or push-to-open. Prior to packaging, the Mighty Mule Gate Opener control board was configured for a single swing gate that pulls-to-open (opens into the property). You must adjust the DIP switches so the control board will recognize and activate both openers. The DIP switches must also be adjusted to control the order in which your dual gate leaves open and close ("gate sequencing"). If you do not adjust the DIP switches, your Mighty Mule Gate

Opener

may not function correctly.

NOTE: To change the DIP switch settings, you must turn the control box power switch OFF;

move the switch; then turn the power back ON. Use a small screwdriver to move the switches.

READ WARNING BELOW!

NOTE: Heavy gates and gates with high wind resistance may require the OBSTRUCT SENS and INERTIA potentiometer to be set closer to MAX to

prevent the opener from obstructing. Keep in mind, however, that while you must determine the best setting for smooth gate operation, you must ALSO determine the lowest possible setting for safe gate operation.

ALWAYS KEEP SAFETY AT THE TOP OF YOUR LIST

WHEN ADJUSTING OR

SERVICING YOUR AUTOMATIC GATE OPENER!

WARNING!

All three potentiometers were set to minimum at the factory. The OBSTRUCT SENS. potentiometer MUST be adjusted above the factory setting for your Mighty Mule Gate Opener® to function properly. If the potentiometer is left at MIN, your gate opener may "obstruct" (i.e., stop and reverse) as soon as it is activated.

BE SURE TO PROPERLY RETEST THE GATE OPENER AFTER MAKING ANY ADJUSTMENTS; FAILURE TO DO SO MAY RESULT IN SERIOUS INJURY OR DEATH!

Page 29

Setting the Closed Positions

HINT: The easiest way to make sure your dual gate closes fully is to set the closed position for each gate leaf one at a time. Set the closed position for the SLAVE gate.

Step 27

Carefully insert the power cable plug (of the SLAVE power cable) into the coupling at the rear of the opener. Turn the plug until it aligns with the pins in the coupling. Push the plug into the coupling until it stops. Finger tighten the sleeve nut to lock the plug into position.

Step 28

Reattach front mount to gate bracket using a clevis pin, washer, and hairpin clip. Press the transmitter button to activate the opener and determine the degree of gate closure. Initially, the push-pull tube will extend only 7-1/2" until the stroke adjustment knob is set (see below right). The maximum extension of the push-pull tube is

/2".

Step 29

To increase the degree of gate closure, loosen the stroke adjustment knob on the bottom of the opener housing and move it

approximately

tighten the knob (DO NOT USE PLIERS OR OTHER TOOLS TO TIGHTEN KNOB). Press the transmitter button to check your

adjustment. To decrease the degree of gate closure, move the stroke adjustment knob away from the gate bracket (see Fig. B).

gate

Step 30

Repeat the procedure in Step 27 until the gate closes firmly as the opener motor shuts down. Each time you adjust the knob, finger tighten it before pressing the transmitter button to check your adjustment.

If the push-pull tube has been extended too far (i.e., if the knob is too close to the gate bracket), the gate will immediately reverse and open after closing. When the knob setting is correct, the gate will close firmly, but not sharply, against the positive stop plate. The motor will run for one-half second after the gate closes against the stop plate. If the motor continues to run for more than one second, the push-pull tube is overextended and further adjustment is necessary. If the motor strains too long against the stop plate, the fuse on the control board (above OPERATOR terminal) will be blown. This blade-style 15 ampere fuse (sold by most automotive supply stores) can be easily replaced. NEVER use a fuse rated higher than 15

amperes!

Step 31

Turn the control box power switch OFF. Disconnect the power cable plug from the coupling of the SLAVE operator with the gate in the fully closed position (do not disconnect the stripped ends on the power cable from the SECOND OPERATOR terminal block).

Step 32

Repeat Step 25 through Step 28 to connect the 4-1/2 foot power cable and set the closed position for the MASTER gate leaf. After you have set the closed position for the MASTER gate leaf, bury the PVC conduit and use the appropriate

material to patch the slot in the driveway.

Step 33

Turn the control box OFF and reconnect the power cable plug and the SLAVE operator. Turn the control box ON and retest the stroke adjustment and sequencing of your dual gate with both openers activated. Make fine adjustments to the stroke knob position and set the SEQ1 and SEQ2 DIP switches if necessary. NOTE: Only make changes to the DIP Switches when the Control Box is turned OFF.

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 Mighty Mule Gate Opener multi-stranded, direct burial wire (see page 27 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 two 5 watt Solar Panel to charge the battery (see Accessory Catalog). Refer to the Solar Panels and Gate Activity chart below.

Solar Panels and Gate Activity

The table and map (at right) illustrate the

maximum number of gate cycles to expect per day in a particular area when using two to three GTO 5 watt solar panels (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.

must be 16 gauge dual conductor,

NOTE: A maximum of three 5 W solar panels can be connected to the Mighty Mule Gate Opener®.

You must connect at LEAST two panels to adequately charge your dual gate opener system. Consult Solar Panel Installation Instructions.

Step 34

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

Step 35

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.

Page 31

IMPORTANT INFORMATION ABOUT LOW VOLTAGE WIRE

STATUS

BATT

PWR. SW.

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 36

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.

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 UL (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 Mighty Mule Gate Opener® is equipped with built-in obstruction sensitivity. The opener is designed to stop and reverse the gate approximately 2 seconds when it comes in contact with an obstruction. However, obstruction sensitivity, even when properly adjusted, may not be sensitive enough to prevent bodily injury in some circumstances. To augment your protection against entrapment, GTO suggests using safety edge sensors or photoelectric sensors. When installed, safety edge sensors (or photoelectric sensors) must be mounted in compliance with UL 325, Underwriters Laboratories safety standard for gate openers. Review page 4 for information about mounting requirements for safety edges ("contact sensors") and photoelectric sensors ("non-contact sensors").

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

Make sure the control box power switch is OFF before connecting safety device wiring to the terminal blocks.

Insert the safety device wires into the CLS EDG terminal on the FIRST OPERATOR terminal block for the gate closing mode. Connect the safety device ground wire to the GRN terminal. Connect the safety device wires for the gate opening mode to the OPN EDG terminal in the same manner.

Repeat the above procedure for the SECOND OPERATOR terminal block.

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" dual gate opens out from the property.

Two (2) Push-to-Open brackets are required for this type of installation (see Accessory Catalog).

The opener is installed while the gate leaf is in the closed position.

Step PTO-1:

With the gate leaf closed, adjust the post bracket assembly and the 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.

Step PTO-2:

While gate leaf is closed, stand inside the property next to the fence post. Using the setback template (insert) measure

4 1/2" back from center of gate hinge, then make a 90º angle toward the gate and measure 4 1/2". This is the point where

either one of the holes at the end of the post pivot bracket should be. You will need to rotate the post pivot bracket or the entire post bracket assembly to align it with the square angle of the template.

NOTE: If you move the post pivot bracket, be sure one of the

post bracket holes is aligned with the rest of the assembly (the center hole should already have a bolt through it). The post pivot bracket can be flipped

over to give more position options.

After verifying that you have complied with the

/2" x 4 1/2" setback, insert the 5/16" x 1 3/4" bolt through the aligned holes of the post bracket and post pivot bracket and fasten it with the 5/16" washer and nut.

To decrease the degree of gate opening, move the stroke adjustment knob away from the gate bracket (see Fig B).

Step PTO-7:

Moving knob away from gate bracket decreases gate opening.

Figure B

Repeat the procedure in step PTO-6 until the gate stops firmly (but not sharply) against the open position stop plate. The motor will continue to run for one-half second after the gate opens against the stop plate. If the motor continues to run for more than one second, the push-pull tube is overextended and further adjustment is necessary. If the motor strains too long against the stop plate, the fuse on the control board (above FIRST OPERATOR terminal) may be blown. This blade-style 15 ampere fuse (sold by most automotive supply stores) can be easily replaced. NEVER use a fuse rated higher than 15 amperes!

NOTE: Each time you adjust the knob, finger tighten it before pressing the transmitter button to check your adjustment.

Page 38

Maintenance & Troubleshooting Guide

If your gate openers do not function properly after installation, use this guide before calling the GTO Service Department.

• On all gate leaves 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 tubes with a soft, dry cloth and apply silicone spray to them at least once per month.

If the Opener 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 openers.

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: This condition indicates the control board is powered up.

1. Replace the transmitter battery with a fresh one.

2. Verify that the power cables are securely connected.

3. Replace the control board fuses if they are blown (15 ampere fuses only - DO NOT USE HIGHER RATED FUSES!).

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.

3. Make sure the battery cables are connected.

IF THE LED IS FLASHING:

The system may be in a condition known as "low voltage lockout" (i.e., inadequate voltage supplied for the gate opener to function).

1. Test (using a voltmeter) the voltage output of the transformer (18.0 to 22.0 VAC) or solar panel (18.0 to 22.0 VDC) at the control board power terminal block.

A. If the voltage is low or not reading, load test the battery at a electronics store and call your dealer for a

replacement battery if necessary.

B. If the voltage is low or not reading, test the transformer and electrical outlet. Replace the transformer if

necessary and let the battery recharge for 12 hours before using the gate opener. C. Check the control board for damage or corroded connections. D. Make sure that telephone or solid core wire is not being used to connect the transformer to the control

board.

Page 39

If the Opener is Working

The Gate CLOSES Then Opens Again on its Own:

1. Check the position of the mounting brackets and readjust if necessary.

2. Check the gate for binding or hinge damage.

3. Check the position of the stroke adjustment knob.

The Gate OPENS Then Closes Again on its Own:

1. Check the position of the mounting brackets and readjust if necessary.

2. Check the gate for binding or hinge damage.

3. Check the position of the stroke adjustment knob.

Column Installation Information

IF THESE OPENERS WILL BE USED WITH GATES THAT ARE MOUNTED ON

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

READ THE FOLLOWING CAREFULLY BEFORE PROCEEDING

Attaching a gate opener to a gate mounted on a masonry column requires special procedures.

Here's how to check your installation to minimize problems:

Open the gate to the 90º position, then measure the distance between the back of the gate and the face of the column. If there is at least a 6 1/4" clearance, you may not have to make any special modifications. However, you must measure the post pivot bracket position using 4 1/2" x 4 1/2" setback, as described on page 14 of this manual, to verify that the gate hinge sits far enough from the column to give your installation the proper setback distance.

If you do not have the proper clearance or setback distance, the opener may operate the gate for a while, but eventually the unit will become nonfunctional. To prevent this problem, we suggest the following installation method:

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

see Accessory Catalog). The crucial 4 1/2" setback 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!

Because of the difficulty associated with column installations, we STRONGLY advise you to call the GTO Service Department at (800) 543-1236 or (850) 575-4144 for assistance prior to your installation.
