Installation Overview for Pull-To-Open Gates PUSH-TO-OPEN installation instructions begin on page 19. Example of an installation on a chain link fence: Control Box / Battery Box 120 Volt indoor Transformer Gate Swings Evenly and Freely Hung Firmly and Plumb First Opener Second Opener (surge protector not supplied) Gate Bracket Closed Position Stop Plates Run 1000' (max.) of low voltage wire to control box from transformer (wire not included).
Installation of the FIRST Gate Opener IMPORTANT: 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 referred to as the FIRST gate and gate opener. The gate and gate opener on the opposite side of the driveway from the control box will be referred to as the SECOND gate and gate opener.
Step 1 Insert the 3/8" x 11/2" bolt through the center hole of the post brackets and post pivot bracket. Secure with a 3/8" washer and 3/8" lock nut. DO NOT overtighten the lock nut (the post pivot bracket will have to be adjusted later). Step 2 Attach post bracket assembly to the rear mount of the opener with a clevis pin and a 3/8" washer. Secure the clevis pin with a hairpin clip.
Step 5 Be sure the position of the gate opener and brackets allows for 1" of clearance between the gate and the opener in both the open and closed position, while at the same time maintaining a stroke distance of 7" to 13" from center of hole in the end of the retracted opener arm to the center of the hole in the gate bracket with the gate in the closed position. This mounting position will give the opener the most efficient leverage point for operation and provides the least possible pinch area.
Step 9 Drill 3/8" holes through post as marked. Fasten post bracket assembly to the fence post using two 3/8" x 8" bolts, washers and lock nuts. You Gate Post Bracket Mounting Examples must use bolts that completely penetrate the post. EXAMPLES TOP VIEW Round Metal Post Step 10 Drill 3/8" holes through the gate cross member as marked. Mount gate bracket using two 3/8" x 2 3/4" bolts, washers, and lock nuts.
Install the Closed Position Stop Plates The closed position stop plate is attached to the FIRST gate to help stabilize the gate leaf in the closed position. An optional low profile ground stop, when used with the closed position stop plate, provides a secure point for the SECOND gate to close against. To further enhance the stability and security of your gate, install a Mighty Mule Automatic Gate Lock [FM143] page 26).
Step 4 Closed Position Stop Plate mounted on the SECOND GATE Mount Vertically Using appropriate hardware for your type of gate, attach the vertical closed position stop plate to the SECOND gate frame at the point where it will come in contact with the low profile ground stop. Do not tighten it completely at this time. You must slide the closed position stop plate toward the low profile ground stop until they touch.
Connecting the Battery Step 4 Verify that the ON/OFF switch is in the OFF position. Battery Connect the BATTERY WIRE HARNESS wires to the battery --- RED wires to POSITIVE (+) battery terminal and BLACK wires to NEGATIVE (–) battery terminal. The BATTERY WIRES from the CONTROL BOARD should extend through the KNOCK-OUT in the back of the CONTROL BOX. Plug the BATTERY HARNESS wires into the wires coming from the CONTROL BOX.
Connect Opener Power Cables Step 1 STATUS 1st OPR. Bring FIRST power cable into the control box through a strain relief slot, leaving enough wire to reach the FIRST OPR. terminal block. OPEN < JOG > CLOSE 2nd OPR. PWR. Insert the individual power cable wires into appropriate terminals on the FIRST OPR. terminal block (white to WHT; green to GRN; red to RED; black to BLK). Tighten the set screws. A dab of petroleum jelly on each terminal will help prevent corrosion.
Step 3 Control and Battery Box First Gate Opener 120 Volt indoor Transformer 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. (surge protector not supplied) Run 1000' (max.
Step 7 Transformer SURGE PROTECTOR Plug the transformer into the electrical outlet. Use of a surge protector with the transformer is strongly recommended. If electrical outlet is located outdoors, outlet and transformer should be protected by a weatherproof cover. Set the CLOSED Position Limit for PULL-TO-OPEN Installation Your transmitter must be able to operate the gate. If not, see "Personalize Your Transmitter Setting" on page 18.
Setting Dual Sense Detection and Auto Close Timer Do not use the Dual Sense Stall Force adjustment to compensate for a gate that is sticking or binding. Excessive Stall Force may cause damage to the gate operator or gate system or Injury or Death. The Stall Force adjustment controls the amount of force the opener will apply against an obstruction before it stops and reverses direction. The adjustment on the control board operates like a volume control on a radio.
Personalize Your Transmitter Setting All GTO transmitters have a standard setting and are ready to operate your Mighty Mule Gate Opener. For your safety and security, we strongly recommend that you replace the factory setting with your own personal setting. NOTE: If you have multiple transmitters, you should adjust all of them at this time. LE Step 1 D Use a small phillips head screw driver to remove the transmitter cover.
