NOT FOR THE CONTAINMENT OF ANIMALS. 2 MM371W / MM372W Installation Instructions

Important Safety Information

Because automatic gate operators produce high levels of force, consumers need to know the potential hazards associated with improperly designed, installed, and maintained automated gate operator systems. Keep in mind that the gate operator is just one component of the total gate operating system. Each component must work in unison to provide the end user with convenience, security, and safety.
This manual contains various safety precautions and warnings for the installer and end user. Because there are many possible applications of the gate operator, the safety precautions and warnings contained in this manual cannot

be completely exhaustive in nature. It does, 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.
Warnings in this manual are identified with this warning symbol. The symbol identifies conditions that can result in damage to the operator or its components, serious injury, or death.

Because Mighty Mule automatic gate operators are only part of the total gate operating system, it is the responsibility of the installer and end user to ensure that the total system is safe for its intended use.

MANUALLY OPENING AND CLOSING GATE

CAUTION
The gate will move freely and uncontrolled when the gate operator is removed from the gate.
ONLY disconnect the operator when the control box power switch is OFF and the gate is NOT moving.

Disconnecting the Operator 1. Turn control box power switch OFF. 2. Remove the hairpin clip and clevis pin. 3. Remove the operator's front mount from the gate bracket.
The gate can be opened and closed manually when the operator is disconnected.

Important Safety Information

FOR THE INSTALLER AND END USER

WARNING

To reduce the risk of injury or death:

1. READ AND FOLLOW ALL INSTRUCTIONS.
2. Never let children operate or play with gate controls. Keep the remote control away from children.
3. Always keep people and objects away from the gate. NO ONE SHOULD CROSS THE PATH OF THE MOVING GATE.
4. Test the gate operator monthly. The gate MUST reverse on contact with a rigid object or stop when an object activates the non-contact sensors. After adjusting the force or the limit of travel, retest the gate operator. Failure to adjust and retest the gate operator properly can increase the risk of injury or death.
5. Use the manual/emergency release only when the gate is not moving.

6. KEEP GATES PROPERLY MAINTAINED. Read the user's manual. Have a qualified service person make repairs to gate hardware.
7. The entrance is for vehicles only. Pedestrians must use separate entrance.
8. 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.
9. SAVE THESE INSTRUCTIONS.

I. Before Installation
1. Verify this operator is proper for the type and size of gate, frequency of use and class of the gate system.
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 entrapment protection devices used with the system (see page 7).
3. Review the operation of the system to become familiar with its safety features. Understand how to disconnect the operator for manual gate operation (see page 3).
4. The gate and operator installation must comply with any applicable local codes.
5. This gate operator is intended for vehicular gates only. A separate entrance or gate must be installed for pedestrian use (see page 8).
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.
7. Identify all of the entrapment zones for the type of installation. An entrapment zone is an area around the automatic gate system where a person or object could be caught that increase the risk of injury. Entrapment zones should be eliminated, guarded or protected.

8. When designing a system that will be entered from a highway or main thoroughfare, make sure the gate system is placed far enough from the road to prevent traffic congestion.

6 MM371W / MM372W Installation Instructions

Important Safety Information

FOR THE INSTALLER AND END USER

Mighty Mule gate operators utilize Dual Sense TechnologyTM entrapment protection. Dual Sense TechnologyTM is built into every Mighty Mule and provides redundant methods of entrapment protection for open and close gate directions.
In addition to Dual Sense Technology, every Mighty Mule gate controller has provisions for the connection of additional obstruction detection devices such as sensing edges and photo beams.
These devices may be located where there is an increased risk of obstruction. Refer to the diagram below.

One or more edge sensors may be located at the leading edge, bottom edge, and post edge, both inside and outside of a vehicular swing gate system.
Wiring to sensors must be located and arranged so the wiring between the sensor and the gate operator is not subjected to mechanical damage.
A wireless sensor such as one that transmits radio frequency (RF) signals that promote safety shall be located where the transmission of the signals is not obstructed or impeded by building structures, natural landscaping or similar objects.

Entrapment and Obstruction Protection

Mighty Mules's Dual Sense TechnologyTM provides entrapment protection. Since all installations are different, you may need to add photo beams or sensing edges to help prevent damage to vehicle or other items that could be hit by a moving gate.
Entrapment Alarm

The Mighty Mule Automatic Gate Operator is designed to stop and reverse the gate when the gate comes in contact with an obstruction. Additionally, these operators 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 operator receives an intended signal from a hard wired entry/exit source (e.g. push button control or keypad). 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.

MM371W / MM372W Installation Instructions 7

Before You Begin
POWERING OPTIONS
1. Determine Charging Option for Battery: Transformer OR Solar
NEVER USE TRANSFORMER AND SOLAR PANEL(S) AT THE SAME TIME. It will damage the control board.
IMPORTANT: The Mighty Mule 371 and 372 are designed and intended for use with a 12 Volt automotive, marine or lawn tractor battery. The battery must be placed inside a weatherproof case and located within 6' of the control box. The 8' battery harness connects the battery to the control board. The battery charge is maintained by the 19 Volt transformer included OR optional solar panel(s). The transformer OR solar panel is connected to the control board using low voltage, 16 gauge, dual conductor, multi-stranded, direct burial wire [RB509] (page 52). I don't believe we need this now that the specifications are in the line above. The transformer is intended for indoor use. If the transformer can only be plugged into an outside electrical outlet, a weatherproof cover or housing must be used. If your gate is more than 1000' from an AC power source, you will need to use a solar panel charging kit (minimum 10 watts) . Refer to the Solar Panels and Gate Activity Chart below.

* If the gate operator controller is OFF, the system will NOT charge the battery.

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 prior to the battery depleting to a state where the unit will not function. The figures shown are for winter (minimum sunlight). Accessories connected to your system will draw additional power from the battery.
A deep cycle marine battery is recommended for solar and/or high traffic applications.
NOTE: UP to 250 ft. of dual conductor, 16 gauge, multi-stranded wire may be used to allow installation of solar panels in direct sunlight.

CHECK EXISTING GATE SIZE AND MATERIAL

· Gate size: Up to 16 feet and up to 550 lbs. -- See Operational Capacity chart on page 10.
Not rated for use on solid surface gates.

· Type of gate material: Vinyl, aluminum, chain link, farm tube, wrought iron, wood.

IMPORTANT: CHECK FOR PROPER GATE INSTALLATION

The gate must be plumb, level, and swing freely on its hinges. The gate must move throughout its arc without binding or dragging on the ground. Wheels must NOT be attached to the gate. Gates over 250 lb. should have ball bearing hinges with grease fittings. Post must be secured in the ground with concrete (minimizes twist/flex when the operator is activated). Make sure there is a stable area for mounting the gate bracket (this may require the addition of a horizontal or vertical cross
member).
We recommend you position the operator near the center-line of a gate to keep the gate from twisting and flexing, and to avoid back-splash from rain.

Maintenance & Troubleshooting
Monthly, test the obstruction and entrapment protection systems. Monthly, service the gate operator (make sure the power switch is OFF). Clean extended operator arm with a soft, dry
clean cloth. 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. Monthly, turn off the power switch and disconnect the Mighty Mule and move the gate to make sure the gate is moving
freely without sticking or binding. Lubricate the hinges or repair the gate as required before reattaching the Mighty Mule. Monthly, check the gate system for potential entrapments from new landscaping or construction. Eliminate or guard as
required. Monthly, check that the warning signs are mounted on each side of the gate and clearly visible. Replace the signs if they
are missing or damaged. Replace batteries every 2-3 years and properly recycle old batteries.
