USER'S MANUAL

BMGi strongly recommends using the services of an experienced gate installer. If you intend to install the operator yourself, this manual must be read carefully before any installation begins. While all reasonable steps have been taken to ensure the gate operator is safe, gates are heavy moving equipment and can cause serious damage or injury if they strike an object or person. The operator has a built-in electronic collision sensing system that stops and reopens the gate if it strikes an object. However, this means the gate will strike the object before stopping. For this reason, 'Safety Beams' are strongly recommended to reduce the risk of the gate striking an object. The installation of beams does not guarantee that the moving gate will not strike an object in its path.

Check the following items before installing the operator:

• The rail is level; the gate must not move on its own at any stage.
• The wheels are turning freely and are not jammed.
• The gate is not bent or bowed in any way.
• The rail has sufficient end stops so that the gate can never run off the end of the rail.
• The gate setup is constructed in such a way that the gate cannot fall over.
• The top rollers are turning freely and are not jammed.
• The gate does not jam in the catch bracket when closing or opening.
• The gate must not exceed the maximum number of operations stated in the specifications.
• Extreme care should be taken when automating a gate that is fully cladded, as wind resistance can cause the gate to not close properly.

Only when all the above points are satisfactory should you proceed with installing the gate operator. Remember, if a gate causes damage or injury, the installer of the equipment may be held liable.

Important Safety Precautions:

• DO NOT CONNECT MAINS VOLTAGE DIRECTLY TO THE CONTROLLER.
• DO NOT CUT THE PLUG OF THE TRANSFORMER AND HARDWIRE; either of these actions may void your warranty.
• Electrical shock can occur while installing this equipment.
• Injury or death by electrocution may lead to lawsuits against the installer/homeowner.
• All wiring should be run in conduit.
• Do not open, tamper with, or modify any of the electronic components of this equipment in any way.
• Do not attempt to repair the equipment; this should only be done by a qualified technician.
• BMGi will not be held liable for any accident/incident resulting in damage, injury, or death ensuing from the incorrect installation of the automatic gate operator.
• Although these operators have built-in collision sensing, substantial damage can still occur. For this reason, 'Safety Beams' should be used on all installations.
• Do not allow children to play near or with any gate, gate operator, or remote control.
• It is the responsibility of the installer to ensure that the gate is in good working condition before automating the gate.
• BMGi cannot be held responsible for a gate bumping either of the end stops if it runs on a slope.
• Do not operate the gate unless within direct sight of the gate.
• A gate is a heavy piece of equipment, and injury, even death, may occur due to incorrect installation or operation. There are a number of areas that may cause entrapment, which could lead to injury:

1. Gate Wheels (Pets at risk when lying at the gate)
2. Between the gate & the end stop
3. The gate, during the closing cycle
4. Between the gate & the catch bracket
5. Pinion Gear
6. Between the gate operator & the gate
7. Gate Rollers
8. The gate during opening cycle

SITE SETUP

GATE PULL AND RUNNING FORCES

The gate Pull and Running Forces must be measured before installing the operator. Should the measured forces exceed those in the table below, then the operator must not be installed. It may be possible to reduce these forces by carrying out maintenance on the gate & rail, but if not, the operator must not be installed. These forces can be measured using a fishing or luggage scale.

Pull Force: Place the gate in the fully open/closed position and pull on the scale until the gate starts moving. The value showing on the scale at the point that the gate starts moving is the Pull Force (kgf).

Running Force: This is the maximum value read while the gate is moving before coming to the fully open position.

Diagram showing a person using a scale to measure the pull force on a sliding gate.

AUTOMATING UNLEVEL GATE

BMGi does not recommend automating a gate which is not level. Failure to level the gate will put undue stress on the operator, and the gate may bump the end stops. Furthermore, if the operator is in manual override mode, the gate may run freely down the slope and present a safety risk.

The gate should always be level. This can be achieved by leveling the track using supports or spacers.

Diagram showing an unlevel gate with a cross symbol (❌) and a level gate with a check symbol (✔️).

ANCHORING THE BASE PLATE

1. Lay a concrete slab 400mm x 400mm x 200mm. Dig a hole and place the conduit in the correct position. Fill the hole with concrete and allow to set.
2. Place the base plate on the concrete slab and feed the conduit through the cable inlet.
3. Maintain a 70 mm distance between the edge of the base plate and the gate.
4. Attach the base plate to the slab, adjust the screws and nuts to level the plate.

Diagram showing the base plate being leveled on a concrete slab.

SECURE THE MOTOR TO THE BASE PLATE

Secure the motor on the base plate via the 2 screws.

1. Position the motor to allow a 20 mm gap between the face of the cog and the face of the gate, then bolt down.
2. Place a spirit level on top of the operator base while fastening the screws, ensuring the operator is level.
3. Manually move the gate fully open and closed very slowly to ensure that the gate does not collide with the operator in any way.
4. Be sure to remove any cement/debris around the pinion gear.

Diagrams illustrating the motor being secured to the base plate and the correct positioning of the motor relative to the gate.

PLACING THE MOTOR IN MANUAL OVERRIDE

When power has failed or you need to manually slide the gate open, turn the key clockwise and pull the lever to release the clutch. The gate can now be operated manually. To lock the gate, push the lever door shut, then turn the key anti-clockwise to lock it again.

Diagram showing the manual release mechanism with a key.

MOUNTING THE RACK ON THE GATE

There must be a 2-3mm clearance between the mounted rack and the cog.

1. Start with the gate in the open position. Place the first piece of rack on the cog, making sure you have the 2-3mm gap between the rack and cog.
2. Fasten the rack to the gate with the self-drilling TEK screws through the slots in the rack.
3. To attach additional rack, slide the gate along and repeat the above procedure until all racking has been installed.

The racking must run the full length of the bottom gate rail, including the tail. Slide the gate back and forth, making sure the gate isn't catching or binding on anything.

Diagram showing the correct clearance between the rack and the cog.

MOUNTING THE LIMIT BRACKETS

Ensure your motor is in manual mode.

1. Open the gate until it hits the ground stop. Pull the gate back 60 mm and install the limit bracket onto the racking. Slide the gate bracket along until it just hits the spring, then screw it to the racking.
2. Slide the gate into the closed position until it hits the catcher stop. Pull the gate back 60 mm and install the limit bracket onto the racking. Slide the bracket along until it just hits the spring and screw it to the rack.

Lock the clutch. Note: Limits may require small adjustments after the gate has performed its learn function.

FUNCTION TESTING

DIGITAL DISPLAY SCREEN SETTINGS

Note: You can only enter the digital menu settings or learn a new remote when the gate has stopped in the closed position or has stopped in the open position (without auto-close activated).

To enter the digital menu settings, press and hold the [FUN] button for about 5s until the digital display shows P0. To select the menu option you require, press INC+ or DEC- until you see the desired number on the digital display. Then press the FUN button to enter the setting. Use INC+ or DEC- to adjust your setting range. Once you have your setting, press the FUN button to exit back to the main menu. You will hear the buzzer sound to confirm it has been stored successfully. If you have finished adjusting your settings, press the LRN button to exit the digital display.

PROGRAM THE LIMITS & OBSTACLE SENSING

Note: Before learning your gate's travel distance (gate opening), ensure you have a physical gate stop in the full close position and full open position, as the motor will use these to learn your opening. The gate must always be in the close limit position (Blue LED on, top left corner). If any interruption happens during the auto-travel learning process, it will cause the auto-travel learn to fail, and you will need to start again.

Steps: Move the gate to the closed limit position. Press the "FUN" and "LEARN" buttons simultaneously for approximately 7 seconds. The gate will then open fully and, after 2 seconds, will close fully. The motor will perform a complete open and close cycle. During the auto-travel learning process, the digital display will show the working time of the complete working cycle. After the gate moves to the close position, the digital display will turn off. If your gate opening and closing times differ by more than 3 seconds, your slow-down speeds may be affected. This may be an issue with the gate setup, not the automation. Please check that your gate is running smoothly, level, and free from any obstructions, and then repeat the above learning step again.

Note: Correct motor function condition should be: when the gate is opening, the blue indicator LED lights up; when the gate is closing, the red indicator LED lights up. Gate direction is important to allow obstruction sensing to work, auto-close, safety beams, pedestrian mode, etc.

Service Schedule

The DC400 gate operator, much like a car, will provide many years of excellent service if a service schedule is carried out at regular intervals. Follow these basic checks and perform repairs in time to get the most out of your operator.

WEEKLY

• Clear away any dirt, sand, stones, or foliage collected on the gate rail.
• Clear away any branches, shrubs, or grass that might interfere with the movement of the gate.

MONTHLY

• Check for damage or cracks to the motor lid. Although the operator lid is designed for outdoor conditions, stones and severe hail may damage it. A cracked lid should be immediately replaced, as water and dirt will damage the operator.
• Check for insect and reptile infestations. It is recommended that mothballs be placed inside the operator housing to discourage these infestations, which can cause damage.

EVERY 6 MONTHS

• Place the motor into manual mode and test the gate by opening and closing slowly. Take note of any tight sections you feel.
• Check for any battery leaks if you have added a battery; these can cause damage to the wiring.
• Check that the controller and other accessories are firmly in place and are not hanging loose.
• Check that the limit brackets on the racking have not shifted.
• Check guide rollers on the gate.
• Check all brackets are secure.
• Check the motor is firmly in place and cannot move.
• Check the rack for any damaged teeth.
