To ensure proper calibration and avoid parameter misalignment, kindly follow the installation instructions for the ADC-AI-S300 model. ### Operator Initialize Programing **Install the operator** following the installation instructions. 1. **Ensure the door is fully closed**, and that the doorway is clear of all obstacles. 2. **Turn the power ON.** The screen will display two options, as shown in the image below: ![](https://cdn.document360.io/698fbf35-46b1-42c8-9a01-0506761ce4e8/Images/Documentation/image-1745966023894.png) 3. **Press the "ACT" button.** The door will perform two automatic self-learning cycles: - Cycle 1: The operator learns the door position (open/close limits). - Cycle 2: The operator calibrates the opening and closing speeds. 4. Upon successful completion, the screen will display: **“DOOR CLOSED”**, indicating the operator is ready for normal use. ![](https://cdn.document360.io/698fbf35-46b1-42c8-9a01-0506761ce4e8/Images/Documentation/image-1745966044661.png)
