Linear Actuator Operator Overview
Wiring Specifi cations
The Model LRA Residential Linear Actuator is designed to open and close a light-duty residential swing gate. The operator can be used in left-hand or right-hand swing gate installations on gate(s) with leafs weighing up to 600 pounds.
The LRA operator (or two LRA operators in dual gate installations) connect by a cable to the APeX electronic controller, which provides all connections for input and entrapment detection devices. The Controller is housed in a separate enclosure and contains a built-in radio receiver for wireless activation by remote control transmitters.
Brackets attached to the gate and gate hinge post are for mounting the operator and to provide a mechanism to move the gate.
When the operator activates, the worm drive in the linear actuator changes the fi xed distance between the two brackets that the operator is mounted on. When the operator pulls the two brackets closer together, the gate opens. When the operator pushes the two brackets farther apart, the gate closes (see Figure 1).
Adjustable magnetic limit switches in the operator detect the open and closed positions of the gate.
WARNING
This operator is intended for installation only on gates used for vehicles. Pedestrians must be supplied with a separate access opening. The pedestrian access opening shall be designed to promote pedestrian usage. Locate the gate such that persons will not come into contact with the vehicular gate during the entire path of travel of the vehicular gate.

1. The distance shown in the table above is measured in feet from the operator to the power source. DO NOT EXCEED THE MAXIMUM DISTANCE. These calculations have been based on a standard 115 V supply with a 10% drop allowable. If your supply is under the standard rating, the runs listed may be longer than what your application will handle, and you should not run wire too near the maximum distance for the gauge of wire you are using.
2. When large-gauge wire is used, a separate junction box (not supplied) may be needed for the operator power connection.
3. Wire length calculations are based on the National Electrical Code, Article 430 and have been carefully determined based on motor inrush and operator requirements.
4. Connect power in accordance with local codes. The green ground
wire must be properly connected.
5. Wire insulation must be suitable to the application.

Mounting Bracket Installation
Examine Figure 2 for details on the required mounting locations for the brackets. They must be mounted at the correct locations to allow the operator to open the gate at a 90 degree angle and to ensure the operator functions smoothly.
The brackets must also be mounted level in respect to each other so the operator’s front and rear mounting points are vertical and not offset at an angle.
LOCATE POST BRACKET AT THESE DIMENSIONS FROM THE GATE CENTERLINE AND HINGE POINT
NOTE: THE 5-1/2" AND 6" DIMENSIONS ARE CRITICAL FOR PROPER GATE OPERATION
6"
WARNING
The gate must be installed in a location so that enough clearance is supplied between the gate and adjacent structures when opening and closing to reduce the risk of entrapment. Swing gates shall not open into public areas.
1. Measure approximately halfway up the gate height and determine good strong spots located in the required areas to mount the brackets on the post and gate.
2. Using Figure 2 as a guide, mark the locations on the post or pillar and the gate for the mounting brackets. The top surface of the post bracket must be 3/8” below the top surface of the gate bracket to allow for the bolt-on operator bracket’s 3/8” thickness.
NOTE: Depending on the gate design, an additional reinforcing
plate welded to the gate may be required to provide a good spot to mount the gate bracket.
Universal Post Bracket Installation
NOTE: When installing the post bracket on a round post or masonry
pillar, use improvised methods (additional plate with lag bolts and anchors, concrete wedge anchors, U-bolts, etc.) to securely fasten the bracket.
1. Tack weld the post bracket to the post at the marked spot and double-check its level and height.
2. Finish welding the post bracket to the gate post and allow the weld to cool.
3. Attach the bolt-on operator bracket to the post bracket at the correct depth and angle using three bolts and locknuts (there are 18 possible positions). Install the operator bracket pin as shown in Figure 3.

The Controller contains two 5-position plug-in terminal blocks for connection to one or two LRA operators. Terminal block MOTOR-1 is used in single gate LRA installations. Terminal block MOTOR-2 is used for the second arm in dual gate LRA2 installations.
To make wiring easy, the terminal blocks are removable and plug into the Controller’s circuit board.
1. Route the operator cable up through the fl uid-tight strain-relief fi tting on the bottom of the Controller’s cabinet.
2. Noting the wire colors, connect the operator cable to MOTOR-1 Terminals 1-5 on the Controller.
3. Route the cable towards the operator. Be sure to leave enough slack in the cable to allow for the gate swing.
4. Remove the operator’s wiring access plate (see Figure 6).
5. Cut the cable to length if required, then slide the O-ring over the end of the cable.
6. Connect the interface cable to the operator’s terminal block matching the same colors and terminal numbers used in Step 2 (see Figure 6).
7. Replace the operator’s wiring access plate being careful to align the O-ring below the cable clamp. The O-ring helps keep out moisture.
For dual gate installations, repeat Steps 1-7 and connect the second operator’s cable to the MOTOR-2 5-position terminal block in the Controller (see Figure 7). Use the strain-relief fi tting that comes with the LRA2 kit where the cable enters the Controller cabinet.

Operator Setup (Continued)
WARNING
ALL AC ELECTRICAL CONNECTIONS TO THE POWER SOURCE AND THE OPERATOR MUST BE MADE BY A LICENSED ELECTRICIAN AND MUST OBSERVE ALL NATIONAL AND LOCAL ELECTRICAL CODES.
AC Power Connection
The control box contains a power disconnect switch to turn on and off the power available to the operator. Following wiring specifi cations on Page 2, incoming power should be brought into the control box and connected to the labeled pigtails from the disconnect box. A wiring connections print can be found on the label inside the cover of the operator. See Figure 8 for power option examples.
Earth Ground
Install a ground rod and connect it to the control box in every installation. A good earth ground is necessary to allow the Controller’s built-in surge and lightning protection circuitry to work effectively.
NOTE: Do not splice the ground wire. Use a single piece of solid
copper 12 AWG wire between the ground rod and the control box.
1. Install an 8-foot long copper ground rod within three feet of the control box.
2. Use a clamp to connect a solid copper 12 AWG ground wire to the ground rod.
3. Route the ground wire to the control box through a wiring knockout.
4. Connect the ground wire to the screw terminal located above the 115V power receptacle on the Controller’s metal chassis.

DISCONNECT (UNLOCK)
Manual Disconnect
In case of a power failure or other condition, the gate can be manually moved without action from the operator by using the manual disconnect switch (see Figure 9).
To activate the manual disconnect switch:
1. Open the cover on the switch.
2. Insert the disconnect key (supplied with operator).
3. Turn the key clockwise 90˚.
4. Reverse the steps to re-engage the operator.
Dual Gate Stagger Delay
This feature is used for overlapping dual gates. After completing setup of the operator, in dual gate installations use the following control to adjust the dual gate stagger:
To delay opening of Gate 1, and delay closing of Gate 2, gently adjust the potentiometer located on the motor board (under the small blue removable cover) clockwise until the desired delay is reached (see Figure 10). Do not turn more than ¾ of a turn or damage will result. Range is 0 to 10 seconds delay.
Only Motor-1 can be delayed on open. Plug the appropriate LRA arm into either the MOTOR-1 or MOTOR-2 terminal block to change which gate is delayed.
