# Core Operating Parameters and Factory Reset

### Description:

This section introduces typical settings for the ADC-AI-S300 door operator, including opening and closing cycle parameters. It also covers how to perform a factory reset to restore default settings.

### How to access the parameter setting menu

1. Ensure the door is fully closed — the control display should show **“DOOR CLOSED.”**
2. Press the **MENU** button on the control board to enter the **Main Menu**.
3. Use the **UP** and **DN** buttons to scroll until **[Settings]** appears on the screen.

4. Press the **SEL** button to enter the **Settings** menu.

5. Scroll using **UP** and **DN** until the desired parameter and its current value are displayed.

6. Press **SEL** again to edit the selected parameter.

7. Adjust the value using **UP** and **DN** until the desired setting is reached.

8. Press **SEL** to confirm and save the new value.

9. Press **BACK** to return to the **Basic Settings** menu and choose another parameter if needed.

10. Press **BACK** again to return to the **Main Menu**.

### Opening Cycle Settings

- **Index 05 – Opening Speed**

Defines the speed at which the door opens.

A higher value results in faster opening, while a lower value slows the motion. Adjust based on safety requirements and pedestrian flow.

- **Index 03 - Backcheck Speed**

Controls the door’s speed during the final 20° of the opening cycle (backcheck zone).

A higher value increases speed; a lower value softens the door’s stop near full open.

- **Index 18 – Deceleration Angle**

Sets the angle at which the door begins to decelerate before entering the backcheck phase.

Higher angles trigger earlier deceleration, resulting in a smoother and quieter stop.

- **Index 04 - Holding Time**

Sets how long (in seconds) the door remains open after reaching the backcheck position. Longer hold times are ideal for environments with slower pedestrians or equipment passage.

- **Index 01 – Overload**

Adjusts obstacle detection sensitivity during the opening cycle.

Lower values increase sensitivity (door reacts faster to resistance), while higher values reduce sensitivity, allowing better performance against wind or pressure.

### Closing Cycle Settings

- **Index 06 – Closing Speed** Defines the speed at which the door closes.  
A higher value increases the closing speed, while a lower value ensures a slower, safer close
- **Index 07 – Latch Speed** Controls the speed during the final latching phase.  
A higher value results in a faster latch; a lower value provides a gentler closing action to reduce noise and wear.
- **Index 17 – Latch Angle** Sets the angle at which the door begins to decelerate before fully closing.  
A wider angle allows for smoother, more controlled final movement and better alignment with the door frame.

### Factory reset

**Index 29 – Factory Test**

- 0 = Normal operation (default) – no reset or action is triggered
- 1 & 2 = Reserved for developer use only (used during internal testing and debugging)
- 3 = Factory Reset – restores all parameters to default factory values and reboots the system

Set the value to 3 to clear all user parameters and reboot the system.

**When to Use:**

- The door operator exhibits **unexpected behavior** or erratic motion due to misconfiguration.
- You want to **erase all user-defined settings** and start fresh with factory defaults.
- The unit is being **reinstalled or repurposed** in a new location or for a new application.
- You're instructed by technical support to perform a system reset as part of troubleshooting.

**Important:** After performing a factory reset, you must reinitialize the operator and reconfigure all relevant parameters before placing the unit back into service.
