INSTALLATION
Step 1 Position the Brackets
If this operator is a replacement for a Miracle-One™ operator, use the existing post bracket and gate bracket. Remove the Miracle-One™ operator from the brackets and proceed to the next step. If your application is Push-to-Open, refer to the illustrations in the Appendix.
The measurements shown below are typical for a standard installation. Your installation may be different. The gate bracket MUST be installed in an area that can withstand heavy forces. Additional reinforcement steel plates may be necessary for mounting.
1. Close the gate.
2. Choose a vertical mounting location for the post bracket. 3. Place a measuring tape under the center of the gate hinge point and measure out dimension A (see chart).
4. Use a screwdriver or dowel rod to temporarily mark the location of the first measurement (Figure 1).
5. Measure out dimension B (see chart) from the previous mark. Use a screwdriver to mark the location of the second measurement (Figure 1).
6. Align the post bracket as close as possible above the screwdriver or dowel rod and tack weld the post bracket in the desired vertical position.
7. Position a level on the post bracket and measure 35-1/2" (90.2 cm) over from the center hole of the post bracket and mark the location on the gate (Figure 2).
8. Measure 2-1/4" (6.4 cm) down from the previous mark and center the bracket on this mark (Figure 3). Tack weld the gate bracket in this position.
NOTES:
● There should only be a maximum of 4" (10.2 cm) from the center of the hinge to the edge of the post or column (Figure 1). If the distance is greater than 4" (10.2 cm) entrapment protection for this area is required.
● While the gate is in the fully open position, the operator needs a clearance of 11-1/4" (28.6 cm) as shown (Figure 2).
NOTE: The ideal installation measurements are A = 7-3/4" (19.7 cm) and B = 8- 1/2" (21.6 cm). If different measurements are used, the sum of A and B cannot be greater than 18" (45.7 cm).
Step 2 Attach the Brackets
1. Insert the key into the lock and turn it 180 degrees counterclockwise. Turn the release lever 180 degrees counterclockwise. The operator is now in manual mode.
2. Position the operator on the brackets and make sure the operator is level and positioned correctly on the gate.
3. Remove the operator from the gate.
4. Completely weld around the post bracket and gate bracket.
NOTE: Brackets may need additional reinforcement by welding flat stock as shown.
5. Attach the operator to the post bracket with the bolt, mounting plate, and nut as shown.
6. Attach gate bracket to operator with the bolt, washer, and nut as shown. Tighten the nut until it reaches the bottom of the gate bracket, then turn the nut a half turn, making sure not to overtighten. Make sure the trolley does not reach the fully open or fully closed position. NOTE: Extra force may be needed to move the trolley back and forth.
For dual gate applications, repeat the previous installation steps to install the second operator.
Step 3 Install the Control Box
Standard Control Box
The control box MUST be mounted within 5 feet (1.52 m) of the gate operator. Mount the control box as high as possible for best radio reception. Make sure the control box is level.
NOTE: The expansion board DOES NOT need to be removed for a wall or column mount installation.
1. Remove the screws and open the control box.
2. Disconnect the "Main Board" connector from the expansion board.
3. Remove the expansion board by removing the screws.
4. Select the mounting holes (according to your application) and remove the knockouts using a screwdriver and hammer.
5. Secure the control box to mounting surface.
A. Wall or Column: Use the provided screws (4).
B. Post: Use U-bolts and rubber washers (not provided) to ensure a watertight seal. Make sure the U-bolts do not protrude more than 3/4 inch from the control box because this can short the control board.
6. Reinstall the expansion board and connect the "Main Board" connector to the expansion board.
Large Metal Control Box
The control box MUST be mounted within 5 feet (1.52 m) of the gate operator. Mount the control box as high as possible for best radio reception. Make sure the control box is level.
NOTE: The Large Metal Solar Control Box (Model XLSOLARCONTUL) does not have the electrical outlets or the expansion board shown in the images.
Wall or Column Mount
1. Open the control box. The control box door may be removed by opening the door 90°. Lift the door from the hinges and set aside until the installation is complete.
2. Remove the toroid assembly from the control box by loosening the three screws and lifting the assembly up and out.
3. Use knock outs located at the 4 corners of the control box and knock out using a screwdriver and hammer.
4. Secure the control box to mounting surface using the provided screws (4).
Post Mount
NOTE: The post mount option is not recommended for the 33AH battery application.
1. Open the control box. The control box door may be removed by opening the door 90°. Lift the door from the hinges and set aside until the installation is complete.
2. The control box can be mounted to a post with 'U' bolts (refer to chart). The knock out will accommodate a 3/8" diameter 'U' bolt. Select center mounting holes (top and bottom) and knock out using a screwdriver and hammer.
3. Secure the control box to mounting surface with U-bolts and rubber washers (not provided) to ensure a watertight seal.
WARNING ● ANY maintenance to the operator or in the area near the operator MUST NOT be performed until disconnecting the electrical power (AC or solar and battery) and locking-out the power via the operator power switch. Upon completion of maintenance the area MUST be cleared and secured, at that time the unit may be returned to service. ● Disconnect power at the fuse box BEFORE proceeding. Operator MUST be properly grounded and connected in accordance with national and local electrical codes. NOTE: The operator should be on a separate fused line of adequate capacity. ● ALL electrical connections MUST be made by a qualified individual. ● DO NOT install ANY wiring or attempt to run the operator without consulting the wiring diagram. ● ALL power wiring should be on a dedicated circuit and well protected. The location of the power disconnect should be visible and clearly labeled. ● ALL power and control wiring MUST be run in separate conduit. |
Step 4 Earth Ground Rod
Use the proper earth ground rod for your local area. The ground wire must be a single, whole piece of wire. Never splice two wires for the ground wire. If you should cut the ground wire too short, break it, or destroy its integrity, replace it with a single wire length.
1. Install the earth ground rod within 3 feet (.9 m) of the operator.
2. Run wire from the earth ground rod to the control box.
NOTE: If the operator is not grounded properly the range of the remote controls will be reduced and the operator will be more susceptible to lightning and surge damage.
Step 5 Wire the Operator Arm to the Control Board
1. Choose a knockout in the bottom of the control box.
2. Insert the operator cable through the provided watertight connector. 3. Insert the operator cable and watertight connector into the knockout. 4. Slide the connector nut onto the operator cable.
5. Connect the operator cable wires to the connector according to the colored label on the connector (white to white, red to red, etc.).
6. Plug the connector into the GATE 1 terminal on the control board as shown.
7. Tighten the connector nut.
If installing two operators, go to the following page.
Step 6 Dual Gate Setup
There are two options for dual gate communication: wired or wireless. Follow the directions according to your application. Do not use wired and wireless communication simultaneously. Wired dual gate applications will have a longer battery standby time than wireless applications. Wireless dual gates will require the installation of two control boxes, one for each operator arm.
1. Wireless Setup
Install a second operator arm and control box:
1. Choose an operator to be the network primary operator. All wireless accessories will need to be programmed to the primary operator. NOTE: We recommend that all accessories and board configurations are set on the primary operator.
2. Press and release the LEARN button on the primary operator. The green XMITTER LED will light. NOTE: The operator will time out of programming mode after 180 seconds.
3. Press and release the LEARN button again on the primary operator. The yellow NETWORK LED will light.
4. Press and release the OPEN test button to assign this operator as network primary.
5. Press and release the LEARN button on the second operator. The green XMITTER LED will light.
6. Press and release the LEARN button again on the second operator. The yellow NETWORK LED will light.
7. Press and release the CLOSE test button to assign this operator as network second.
Both operators will beep and the yellow NETWORK LEDs will turn off indicating programming is successful.
2. To deactivate the wireless feature:
1. Press and release the LEARN button on either operator. The green XMITTER LED will light.
2. Press and release the LEARN button again on the same operator. The yellow NETWORK LED will light.
3. Press and hold the LEARN button for 5 seconds. The yellow NETWORK LED will blink (operator will beep) then turn off indicating successful deactivation.
4. Repeat the steps for the other operator.
3. Wired Setup
Install a second operator arm by following installation steps 1-2.
Install the extension cable and junction box:
Before digging, contact local underground utility locating companies.
1. Trench across driveway to bury the extension cable. Use PVC conduit to prevent damage to cables.
2. Open the junction box by removing screws (4) and set aside.
3. Select holes to be used for mounting and knock out using a screwdriver and hammer. Drill two holes in the junction box large enough for the watertight connectors.
4. Mount the junction box within 3 feet (0.9 m) of second operator.
5. Route operator cable and extension cable through watertight connector nut and watertight connector.
6. Insert the cables and watertight connectors into the holes in the junction box.
7. Slide the connector nut onto the operator cable and extension cable.
8. Connect the wires from extension cable and operator cable to the terminal block connector as shown (like-colored wires must face each other).
9. Put wires inside of junction box.
10. Secure operator and extension cables by tightening the connector nut.
11. Reinstall cover.
4. Wire the secondary operator arm to the control board:
1. Choose a knockout in the bottom of the control box.
2. Insert the extension cable through the watertight connector.
3. Insert the extension cable and watertight connector into the knockout.
4. Slide the connector nut onto the operator cable.
5. Connect the extension cable wires to the connector according to the colored label on the connector (white to white, red to red, etc.).
6. Plug the connector into the GATE 2 terminal on the control board as shown.
7. Tighten the connector nut.
5. Set the bipart delay (single control box):
Occasionally in dual gate installations, one gate will need to open first and close second. This would happen if there was an ornamental overhang on one gate or if using a solenoid lock, for example. This gate is called the Primary gate and needs to be connected to Gate 1 connections on the control board. Thus, it is preferred that the control box be installed on the same side as this gate. If there is no appropriate location on that side for the control box, then mount the control box on the opposite side, but connect the operator closest to the control box to the Gate 2 connector and the operator on the opposite side to the Gate 1 connector.
1. The BIPART DELAY switch on the control board needs to be set to the ON position.
The illustration shows a dual gate configuration with a decorative overlapping piece on the outside of the gate.
Set the bipart delay (dual control box)
The BIPART DELAY switch is used with dual control box applications and serves two functions:
● BIPART DELAY: The BIPART DELAY is used in applications where a mag-lock, solenoid lock, or decorative overlay would require one gate to close before the other. The control box with the BIPART DELAY switch ON will delay from the close limit when opening and be the first to close from the open limit.
● SYNCHRONIZED CLOSE: The BIPART DELAY is also used in applications where one gate travels a longer distance than the other. To synchronize the closing of the gates, set the BIPART DELAY switch to ON for both control boxes.
WARNING To prevent SERIOUS INJURY or DEATH from a moving gate:
● ALL gate operator systems REQUIRE two independent entrapment protection systems for each entrapment zone.
● Entrapment protection devices MUST be installed to protect anyone who may come near a moving gate. the manual provided with your entrapment protection device.
● Locate entrapment protection devices to protect in BOTH the open and close gate cycles.
● Locate entrapment protection devices to protect between moving gate and RIGID objects, such as posts, walls, pillars, columns, or operator itself.
Step 7 Install Entrapment Protection
Entrapment protection MUST be installed according to the following UL 325 requirements:
● Swing gate operators require the installation of the first external monitored entrapment protection device to function.
● Every installation is unique. It is the responsibility of the installer to ensure that ALL entrapment zones are protected with an external monitored entrapment protection device, protecting both the open and close gate cycles.
● LiftMaster monitored external entrapment protection devices MUST be used with LiftMaster operators to meet UL325 requirements, see Accessories.
● Test ALL entrapment protection devices after completing installation of the operator. For testing instructions, refer to the manual provided with your entrapment protection device.
● Locate entrapment protection devices to protect in BOTH the open and close gate cycles.
● Locate entrapment protection devices to protect between moving gate and RIGID objects, such as posts, walls, pillars, columns, or operator itself.
Definitions
ENTRAPMENT: The condition when a person is caught or held in a position that increases the risk of injury.
SWING GATE ENTRAPMENT ZONE: Locations between a moving gate or moving, exposed operator components and a counter opposing edge or surface where entrapment is possible up to 1.8 m (6 ft) above grade. Such locations occur if during any point in travel:
a. The gap between the bottom of a moving gate and the ground is greater than 101.6 mm (4 in) and less than 406 mm (16 in); or
b. The distance between the center line of the pivot and the end of the wall, pillar, or column to which it is mounted when in the open or closed position exceeds 101.6 mm (4 in). Any other gap between a moving gate and fixed counter opposing edges or surfaces or other fixed objects is less than 406 mm (16 in) (examples are walls, curbs, berms or other immovable objects).

Wire Entrapment Protection Devices
There are three options for wiring the entrapment protection devices depending on the specific device and how the device will function. Refer to the specific entrapment protection device manual for more information. These entrapment protection device inputs are for monitored devices, which include pulsed photoelectric sensors, resistive edge sensors, and pulsed edge sensors. Only one monitored entrapment protection device may be wired to each input. Additional entrapment protection devices may be wired to the expansion board.
Control Board
CLOSES EYES/INTERRUPT
(2 Terminals) The CLOSE EYES/INTERRUPT input is for photoelectric sensor entrapment protection for the close direction. When an obstruction is sensed during gate closing the gate will open to the full open position and resets the Timer-to-Close. This input will be disregarded during gate opening.
CLOSE EDGE
(2 Terminals) The CLOSE EDGE input is for edge sensor entrapment protection for the close direction. When an obstruction is sensed during gate closing the gate will reverse to the full open position, disengaging the Timer-to-Close. This input will be disregarded during gate opening.
OPEN EYES/EDGE
(2 Terminals) The OPEN EYES/EDGE input is for photoelectric sensor or edge sensor entrapment protection for the open direction. When an obstruction is sensed during gate opening the gate will reverse for 4 seconds then stop. This input will be disregarded during gate closing.
EYE ONLY and COM
Open or Close Direction Photoelectric Sensors, the functionality is based on the switch settings (located next to the terminals)
- Switch set to CLOSE: gate reverses fully when an obstruction is sensed
- Switch set to OPEN: gate reverses 4 seconds when an obstruction is sensed
EYE/EDGE and COM
Open or Close Direction Photoelectric Sensors or Edge Sensor, the functionality is based on the switch settings (located next to the terminals)
