2.1. Mounting the Operator
Securely mount the primary operator unit according to the provided mounting template and local building codes. Ensure the mounting surface is stable and level to prevent operational issues.

Activate the gate opener using a compatible access control device (e.g., remote control, keypad, intercom system). The gate will open or close smoothly based on the command received.
3.2. Safety Features
The system includes a selectable shadow/reverse loop function. This feature enhances safety by detecting vehicles or obstructions in the gate's path, preventing accidental closure or impact. Ensure all safety devices are properly installed and tested.
3.3. Power Outage Operation (Optional)
If your unit is equipped with the factory-installed DC Convenience Open option, the gate will automatically open in the event of a power failure, providing egress. This feature relies on a backup power source within the unit.
