The Mighty Mule gate opener system is designed for do-it-yourself installation, offering a complete line of solar compatible and smart automatic gate openers. This article details installation procedures, safety precautions, and component information based on available documentation. The system is intended for use with single swing gates and can be adapted for different gate types through control board settings. Proper installation and adherence to safety guidelines are crucial for reliable operation and to prevent potential injury.
System Components and Overview
The Mighty Mule gate opener package includes several key components. A typical single gate opener parts list consists of the gate opener unit itself, a gate bracket, an installation video, a closed position stop plate, a post pivot bracket, two post brackets, and a customer support card. Hardware includes four 3/8” x 8” bolts. Additional components, sold separately, include solar panels, replacement transformers, and power cables for remote control box mounting. The system utilizes a 12V battery, with charging circuits operating between 12.0 and 14.8 Vdc.
Safety Instructions and Warnings
Prior to installation, it is essential to review the provided safety instructions. The documentation emphasizes the importance of reducing the risk of injury or death by reading and following all instructions. When installing a system near a highway or main thoroughfare, the gate should be positioned far enough from the road to prevent traffic congestion. Warning signs alerting people to the automatic gate operation are required and must be replaced immediately if damaged or illegible. A walk-through gate is recommended if pedestrian traffic is anticipated near the vehicular gate. Children and pets should not be allowed near the gate, and children should never operate or play with the gate controls. Remote controls should be kept away from children and unauthorized users.
Installation Procedures
The installation process involves several steps, beginning with ensuring the gate is plumb, level, and swings smoothly on its hinges. The opener should be installed on the gate, and the open and closed position stops should be securely in place.
Powering the System
The system requires a power source. If the gate is more than 1000 feet away from an AC power source, a Mighty Mule solar panel is recommended to trickle charge the battery. The power cable plug must be carefully inserted into the coupling at the rear of the opener, aligning the plug with the pins and pushing it in until it stops. The sleeve nut should then be finger-tightened to lock the plug in position.
Wiring the Control Panel
Wiring the control panel involves connecting wires to the appropriate terminals. The documentation specifies using 16 gauge dual conductor, multi-stranded, direct burial wire, and limits the maximum wire length to 1000 feet. The red wire connects to the RED terminal, and the black wire connects to the BLK terminal. A dab of petroleum jelly on each terminal can help prevent corrosion. Crimping a spade tongue terminal to the end of each wire before attaching it to the transformer is suggested.
Control Board Settings
The Mighty Mule gate opener control board is pre-configured for single swing gates that pull-to-open. However, four DIP switches on the control board allow for adjustments to match the gate type. These switches determine whether the gate pulls-to-open or pushes-to-open.
Adjusting Potentiometers
All three potentiometers on the control board are set to minimum at the factory. The OBSTRUCT SENS. potentiometer must be adjusted above the minimum setting for the gate opener to function correctly. Leaving this potentiometer at the minimum setting may prevent the gate from operating and could create a safety hazard.
Entrapment Protection
The Mighty Mule gate opener incorporates Type A, an inherent entrapment sensing system, as the primary form of protection. Provisions are also available for connecting Type B1 or B2 protection as a secondary measure, if desired.
Transmitter Codes
All GTO transmitters are set to a standard code at the factory and are ready for immediate operation. However, for enhanced security, it is strongly recommended to replace the factory setting with a personal code.
Troubleshooting and Maintenance
The documentation recommends consulting the Maintenance & Troubleshooting Guide for initial problem-solving. If the issue persists, the GTO Service Department can be contacted at (800) 543-GATE or (850) 575-0176. When contacting support, it is important to have the serial number (located on the control box cover) and the date of purchase readily available.
Accessory Information
Several accessories are available to enhance the functionality of the Mighty Mule gate opener system. These include:
- Solar Panel (FM121): A solar-powered battery charger, particularly suited for remote installations. It carries a 2-year warranty.
