4. Setup and Installation
The TOPENS KD702 is designed for straightforward installation. Follow these steps carefully. No welding is required, and common tools are sufficient.
4.1 Pre-Installation Checklist:
- Ensure your gate is in good working condition, swinging freely without binding.
- Verify gate dimensions and weight are within the KD702's capacity (max 3.6m / 140kg per leaf).
- Gather necessary tools (e.g., drill, wrenches, measuring tape, level).
- Plan the wiring path for AC power and accessories.
4.2 Mounting the Actuators:
The KD702 supports two installation modes: pull-to-open (gate swings inwards) and push-to-open (gate swings outwards). Choose the appropriate mode for your gate.

Refer to the detailed diagrams in the manual for precise mounting point measurements (A, B, C dimensions) to ensure optimal gate travel and performance. Securely attach the mounting brackets to the gate post and gate frame, then connect the actuators.
4.3 Wiring the Control Box:
Connect the actuator motors, AC power, and safety accessories (photocell, flashing light) to the control board inside the control box. Ensure all connections are secure and follow the wiring diagram provided in the full manual.

4.4 Limit Switch Adjustment:
Adjust the electromagnetism limit switches on each actuator to define the open and closed positions of your gate. This is crucial for proper operation and preventing over-travel.
4.5 Optional Accessories:
The KD702 is compatible with a range of TOPENS accessories to enhance functionality and convenience, such as wireless keypads (TKP3), external receivers (ERM12), and vehicle sensors (TEW3).

5. Operating Instructions
Once installed and configured, operating your TOPENS KD702 gate opener is simple.
5.1 Remote Control Operation:
Press the designated button on your M12 remote control to open or close the gate. A single press will initiate the gate movement. If the gate is already moving, a press will stop it. Another press will reverse its direction.

5.2 Automatic Closing Function:
The KD702 features an adjustable auto-close timer (0-99 seconds). After the gate fully opens, it will automatically close after the set delay. This feature can be enabled or disabled and adjusted via the control board settings.
5.3 Soft Start and Soft Stop:
The gate opener is designed with soft start and soft stop functionality, ensuring smooth and quiet operation, which extends the lifespan of the motor and gate hardware.
5.4 Manual Release:
In the event of a power outage or if the remote control is lost, insert the manual release key into the actuator's lock cylinder and turn it to disengage the motor. This allows you to open or close the gate by hand.
6. Maintenance
The TOPENS KD702 is designed for minimal maintenance. Regular checks will ensure optimal performance and longevity.
- Monthly: Inspect the gate and hinges for any signs of wear or damage. Ensure the gate moves freely without obstruction when manually operated.
- Quarterly: Check all mounting hardware for tightness. Verify that the photocell beams are clean and properly aligned. Test the obstruction detection feature by placing a soft object in the gate's path.
- Annually: Lubricate any moving parts of the gate (hinges, pivots) as recommended by your gate manufacturer. Inspect wiring for any signs of damage or fraying.
- Battery Check (if applicable): If using backup batteries, check their charge level and condition periodically.
