1. Tools Needed for Sliding Gate Opener Installation

Before starting, gather essential tools and materials:

• Drill with a 1/2" concrete bit
• Mason line
• Level
• Anchor bolts
• Welding equipment or bolt-on brackets
• Screwdrivers
• Wrenches (various sizes, mostly 5/16" and 3/4")
• Wire strippers

2. Unboxing and Organizing Slide Gate Opener Components

Unbox your sliding gate opener system and lay out all parts, including the main chassis, control board, cover, mounting hardware, and safety sensors. Verify that every component listed in the gate opener installation manual is included.

3. Preparing the Concrete Pad and Wiring

 

1. Concrete Pad: Set up a 24" x 24" x 24" concrete pad below the frost line to prevent shifting. Leave about 4–6 inches above ground for stability and moisture control.
2. Conduits and Wiring: Run conduits for power, low-voltage connections, and loop wires (for vehicle detection loops, if applicable). Pull the necessary wires through, ensuring they reach the gate opener’s control board.
3. Vehicle Detection Loops: Install in-ground vehicle detection loops as specified in your sliding gate layout, positioned in front of and behind the gate.

4. Positioning and Mounting the Gate Opener

1. Position the Chassis: Place the chassis approximately 1–4 inches away from the face of gate - as recommended. This spacing prevents contact of the cover with the gate during movement. Ensure the chassis is parallel to the gate’s path to allow for smooth, unobstructed movement. Use a level to confirm the chassis is horizontally aligned. Temporarily attach the cover and manually open and close the gate to confirming there is no contact between the cover of the gate opener and the gate itself. Adjust chassis for clearance as needed.
2. Final Clearance Check: Manually operate the gate again to ensure it remains parallel to the gate track without touching the chassis or its cover.
3. Mark and Drill Anchor Points: With the chassis positioned in the correct place, use a marker to mark each mounting hole (through the chassis and onto the concrete), then remove chassis.
4. Drill and Secure with Anchor Bolts: Using a 1/2-inch concrete drill bit - drill holes at the marked points. Reposition the chassis, insert anchor bolts, and tighten them securely.

5. Setting Up the Chain

1. Using Mason Line for Alignment: Use a mason line string to simulate the chain’s path, visualizing alignment under the chain roller, sprocket, and idler pulleys.
2. Positioning and Securing Chain Brackets: Clamp the front chain bracket to the gate frame in its correct position, ensuring it’s level. Thread the mason line through the bracket’s mounting hole to act as a temporary placeholder for the chain. Pull the mason line tight to confirm it runs straight through both the front and rear chain brackets or idler pulleys
3. Installing Chain Brackets: With the mason line taut and aligned, secure the chain brackets using tack welds, bolts, or full welds. Ensure the brackets are firmly fixed before proceeding.
4. Attaching the Chain to the Chain Bolt: Replace the mason line with the chain bolt, securing it with the provided hex nuts on both sides. Leave enough threading for future adjustments. Attach the chain to the chain bolt's "eye" using the master link, ensuring the master link is firmly secured.
5. Running the Chain Through the System: Route the chain from the chain bolt through the front chain idler (located at the back of the chassis). Continue guiding the chain around the chain sprocket and through the second chain idler, ensuring it follows the designed path for your specific setup. Finally, attach the chain to the rear chain bracket. Use a chain breaker if necessary to adjust the chain length for your custom gate size. 
6. Final Alignment and Testing: Switch the gate opener to manual override mode. Slide the gate open and closed to check for smooth movement and proper alignment. If tack welds were used during bracket installation, complete the welds once alignment is confirmed.

6. Installing the Photoeye and Secondary Safety Devices

1. Mounting and Aligning the Primary Photoeye: Begin by mounting the primary photoeye on the guide roller post. Align it carefully with the reflector positioned directly on the opposite side of the gate path. Run the photoeye wiring to the control panel, ensuring proper routing for protection and neatness. Do not power on the system yet.
2. Connecting the Photoeye Wiring: Connect the photoeye wires to the appropriate terminals in the control panel. If the photoeye has polarity requirements, confirm the connections match the manufacturer’s specifications for proper operation.
3. Install the Secondary Safety Device: To ensure safe operation, sliding gates require a secondary safety device. You can choose one of the following options:

• Safety Edge: Attach a safety edge to the rear side of the gate. Secure the transmitter unit onto the gate and connect the safety edge wiring to the transmitter. Then, wire the receiver into the main control board’s safety terminals, ensuring all connections are secure and properly aligned with the control panel’s settings.
• Second Photoeye: Install an additional photoeye on the opposite side of the gate to monitor the open path. Follow the same alignment, mounting, and wiring steps as the primary photoeye to ensure proper functionality.

7. Power and Alignment

1. Connect Main Power: Connect the main power wires to the designated control board terminals, but don’t turn on the power until both safety devices are installed.
2. Turn on Power and Align the Photoeye: With both safety devices installed, turn on the power to the gate opener. Use the alignment LEDs on the photoeye to confirm a clear line of sight with the reflector. Adjust as needed, securing the reflector once aligned.
3. Pair the Transmitter and Receiver for the Safety Edge: If using a safety edge with a wireless transmitter, pair it with the receiver unit on the control board, following the manufacturer’s pairing instructions.

8. Testing the Safety Devices

1. Photoeye Test: Begin a closing cycle on the gate. Break the photoeye beam by placing an object in its path. The gate should reverse direction when the beam is interrupted. Confirm this feature functions reliably.
2. Safety Edge or Secondary Photoeye Test: On the open cycle, activate the safety edge by pressing it or break the secondary photoeye beam (if installed) to ensure the gate stops immediately.
3. Final Safety Verification: Once all safety devices are verified to stop or reverse the gate as intended, run a full open and close cycle to confirm smooth operation with both the safety edge and photoeye functioning correctly.
4. Note: Only proceed to add accessories like receivers, remotes, loops, keypads, and telephone entry systems after ensuring all safety devices are operating correctly.

9. Adding Accessories for Enhanced Gate Opener Functionality

With the gate opener fully installed and tested, you can add optional accessories to improve convenience and functionality, such as remotes for easy access, keypads for secure entry, card readers for high traffic locations, in-ground loops for automatic opening/closing for vehicles, and telephone entry systems for additional security and access control.
