E-Z GATE OPENERS

PLEASE READ THIS FIRST!
Thank you for purchasing a Mighty Mule 350 E-Z Gate OpenerGTO's "do-it-yourself" automatic gate opener! When correctly installed and properly used, your Mighty Mule E-Z 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 E-Z Gate Opener. The Mighty Mule 350 E-Z Gate Opener is designed for installation on a pull-to-open single leaf gate (gates that open into the property). By purchasing an accessory bracket (FM148), the Mighty Mule E-Z Gate Opener can accommodate a push-to-open single leaf gate (gates that open out from the property). The gate 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 E-Z 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 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 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 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 NOTEIf 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 videotape and read these instructions carefully and completely to become familiar with all parts and installation steps. The video tape is only designed as a 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

Front Mount
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.

Clevis Pin Gate Bracket

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

Bushing

Hairpin Clip

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 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 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.

Vehicular Gate

Bottom Edge Contact Sensor on both sides of the gate
Post Edge Contact Sensor on both sides of the gate
The Mighty Mule E-Z 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.

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.

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.
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.

NOTE: The following steps are intended for pull-to-open gate installations. If you are mounting your opener on a push-to-open gate (e.g., a gate on a sloped driveway) you will need to purchase a Push To Open bracket (FM148) (see Accessory catalog). Also, see Pushto-Open Installation beginning on page 33.

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

Powering the System

The Mighty Mule 350 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 opener arm. The battery charge is maintained by the 18 Volt transformer included or by using optional solar panel(s). The transformer or solar panel is connected to the opener arm control board using low voltage, 16 gauge, dual conductor, multi-stranded, direct burial wire (FM509) (seepage 23 and the Accessory Catalog).
All low voltage wire used with the Mighty Mule Gate Opener must be 16 gauge dual conductor, multi-stranded, direct burial wire (see page 20 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 5 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 willl damage the control board

Installing Batteries
NOTE: 3 AA batteries are required to power the keypad unless an external power supply such as the gate openers power source is used. Low voltage wire from the external power source must be connected to the POWER IN terminals on the keypad control board, if batteries are not installed. Step 1: Remove the two screws from the bottom of the keypad and separate the keypad from its housing. Step 2: Install 3 AA batteries (not included).
Pressing this button for 2 seconds will reprogram key pad to factory settings. All codes are deleted. Default master code is 1234.

Battery Holder:

Use 3 AA batteries if hard-wired power supply is not used. If external power source is used the 3 AA batteries will provide a back-up power source.
Wireless Installation of the Keypad
NOTE: For wireless applications, the distance from the keypad to the openers receiver should not exceed 50 ft. Always test the keypad range before permanently mounting it. Step 1: Mount the keypad cover using the screws provided. Set the keypad DIP switches to match your entry transmitters DIP switch settings.

NOTE: If you have not changed your openers transmitter code from the factory setting, see the Setting Your Personal Transmitter Code section in the gate openers manual then set the keypad DIP switches to match the new transmitter DIP switch setting.
Step 2: Slide the keypad into the cover and secure with the small screws provided.
Wired Installation of the Keypad
NOTE: If you also plan to power the keypad with the gate openers power source, run two pairs of wires as described below. One pair to hard-wire the keypad and the other pair to connect the keypad to the gate openers battery. Step 1: Turn the gate openers power switch OFF. Use 16 gauge, stranded, direct burial low voltage wire (part no. RB509) to connect the keypad to the opener control board. Run wire through PVC pipe from the ground to keypad and from the ground to the opener control board to protect the wire from lawn mowers or grazing animals. Determine how the wire will enter the keypad (i.e. from the back through a hole drilled in the mounting post or running the wire on the surface of the post). Remove the small rectangular knock-out on the back of the keypad cover and pull the wire into the cover. Then mount the cover to the post using the screws provided.

Knock-out

Step 2: To hard-wire the keypad - strip the wires back 3/16 and attach the wires to the terminal block marked RELAY OUTPUT on the keypad control board as shown to the right. Connect the other end to the openers control board as shown in Control Board Connections section below. To wire the power supply to the keypad attach the wires to the AC/DC POWER IN terminal on the keypad control board as shown to the right. Connect the other end to the openers battery - one end to the POSITIVE pole and the other to the NEGATIVE pole.

Jumper OFF

NOTE: For a hard-wired application the jumper between the two terminals on the keypad control board must be connected (ON) as shown. This will disable the 318 MHz RF transmitter. Step 3: Slide the keypad into the cover and secure with the small screws provided.

Programming the Keypad

Programming Interface:
All codes are four (4) digits in length. Entry code is a four (4) digit code needed to activate the gate. Master Code is needed to add, remove or reset entry codes. Master Code also functions as the entry code under normal operation. Factory default Master Code is 1234. STATUS light should blink and beeper should beep (once) whenever any button is pressed. If more than 10 seconds elapsed between key presses the unit returns to normal (idle) operating mode. Keypad can only enter program mode from sleep mode (keypad is turned OFF). Keypad will beep three times before going into sleep mode.
Program (Add) New Temporary Entry Code:
Press and release PROGRAM button. Enter the Master Code then press and release PROGRAM button. Enter 8, and any number between 1 thru 7 then press and release the PROGRAM button. The second number indicates the number of days after which the code will be automatically removed from memory NOTE: If memory is full (all 25 locations are already programmed) or an invalid entry is detected then an error condition has occurred, the STATUS light will ash rapidly and the beeper will sound for 2 seconds before returning to normal operation, without saving. Enter the new Entry Code then press and release PROGRAM button. Beeper beeps 3 times to conrm that the new Entry Code is accepted. NOTE: If the code is NOT 4-digit in length or an error condition has occurred, the STATUS light will ash rapidly and the beeper will sound for 2 seconds before returning to normal operation, without saving. Example: Key press sequence to add 3456 as a new entry code that will remain valid for 2-days only. (1234 is the Master Code) The round black dot is the PROGRAM button. Example: Key press sequence to add 3456 as a new entry code that will remain valid for 7-days only. (1234 is the Master Code)

Program New Master Code:

Press and release PROGRAM button. Enter the old Master Code then press and release PROGRAM button. Enter 0, 6 then press and release PROGRAM button Enter the new Master Code then press and release PROGRAM button. Enter the new Master Code then press and release PROGRAM button again for conrmation. Beeper beeps 3 times to conrm that the new Master Code is accepted. NOTE: If the Master Code is not a matched pair or error occurs (i.e. if the entry code is NOT a 4-digit code) the STATUS light will ash rapidly and the beeper will sound for 2 seconds before returning to normal operation with old Master Code. Example: Key press sequence to change old Master Code from to The round black dot is the PROGRAM button.

Example: Key press sequence to delete entry code 3456 from memory. (1234 is the Master Code)
Program (Add) New Entry Code:
Press and release PROGRAM button. Enter the Master Code then press and release PROGRAM button. Enter 0, 2 then press and release PROGRAM button. NOTE: If memory is full (all 25 locations are already programmed) the STATUS light will ash rapidly and the beeper will sound for 2 seconds before returning to normal operation, without saving. Enter the new Entry Code then press and release PROGRAM button. Beeper beeps 3 times to conrm that the new Entry Code is accepted. NOTE: If the code is NOT 4-digits in length or an error condition has occurred, the STATUS light will ash rapidly and the beeper will sound for 2 seconds before returning to normal operation, without saving. Example: Key press sequence to add 3456 as a new entry code. (1234 is the Master Code) The round black dot is the PROGRAM button.

Delete ALL Entry Codes:

Press and release PROGRAM button. Enter the Master Code then press and release PROGRAM button. Enter 0, 7 then press and release PROGRAM button. Beeper beeps 3 times to conrm that the All Entry Codes are deleted. Example: Key press sequence to delete all entry codes from memory. (for example if 3121 is the Master Code)

Normal Keypad Operation:

If the user enters a 4-digit code that is matched to one of the 25 stored codes. The STATUS light should blink twice and the beeper should beep twice to conrm that a matched code is entered. No more than 20 key presses are allowed to obtain the 4-digit entry code. Example: 1234 is one of the codes stored in one of the memory location. The user can enter x1234 or xxxxxxxxxxxxxxxx1234 and the gate should be activated (x is any key). If more than 20 key presses is entered without matching one of the codes then the units STATUS light should be ashing rapidly and no entry will be accepted for the next 40 seconds. The user must not enter any code for at least 40 seconds before the unit returns to normal operation; otherwise it remains in this lock-down mode. Once the user enters a matched code, any subsequent key press within the next 40 seconds will re-activate the keypad.
