These parameters help optimize performance in challenging environments such as high wind areas, pressure-sealed doors, or accessibility-focused applications. ### Power Close and Speed | **Index** | **Parameter** | **Description** | **Function Behavior / Effect of Adjustment** | **Value** | **Default** | | --- | --- | --- | --- | --- | --- | | 11 | Power Close | Powered closing of door to positive latch (toggle) 0 = OFF, 1 = ON | Enables powered closing to fully latch the door. Useful in **high-pressure environments** or where positive latching is required. | 0-1 | 0 | | 12 | Power Cls Spd | Power closing force adjustment | Adjusts the force applied during power closing. **Higher** values provide **stronger** force to overcome resistance. | 1-35 | 20 | | 13 | Powr Cls Angle | Power Closing engage angle | Sets the door angle at which power closing begins. **Larger** angles start power closing **earlier** in the cycle. | 10-45 | 15 | **Introduction:** The power close feature enhances door latching performance in environments where additional closing force is required, such as pressurized rooms or areas requiring secure sealing. **When to Use:** Use this setting when the door fails to fully latch due to air pressure, gasket resistance, or mechanical misalignment. Also useful in outdoor or high-wind installations. **Notes and Tips:** - Excessive force may result in increased wear or user safety concerns. ### Wind Brake Setting | **Index** | **Parameter** | **Description** | **Function Behavior / Effect of Adjustment** | **Value** | **Default** | | --- | --- | --- | --- | --- | --- | | 21 | Wind Brake | Turn ON/OFF wind break feature 0 = OFF, 1 = ON | When enabled, the wind brake helps resist wind pressure during **door opening**, improving stability in windy environments. | 0-1 | 0 | | 22 | Wbrake Speed | Wind buffer force | Sets the strength of the wind buffer. Lower values apply greater resistance against wind. | 1-99 | 10 | | 23 | Wbrake Angle | Wind buffer engage angle | Defines the door angle where wind buffer engages. Adjust to tailor wind resistance response timing. | 25-110 | 60 | **Introduction:** The wind brake function helps resist wind pressure during door opening, helping to stabilize movement against wind or pressure variations. **When to Use:** Activate this setting in outdoor environments or locations with frequent strong air currents that affect door movement **Notes and Tips:** - When Wind Brake is ON, users must push the door fully open to engage the system correctly. - A quick release after a partial push may be misinterpreted as an obstruction. ### Preload Setting | **Index** | **Parameter** | **Description** | **Function Behavior / Effect of Adjustment** | **Value** | **Default** | | --- | --- | --- | --- | --- | --- | | 19 | Preload Time | Pull time door before opening to release pressure (10th of second) | Sets the duration the door pulls in before opening to relieve pressure. Adjust the value if there’s trouble with an electric strike. | 0-50 | 0 | | 20 | Preload Spd | Pull force of door before opening to release pressure | Adjusts the force of the preload pull before opening. Higher values increase pulling force to overcome pressure seals. | | 50 | **Introduction:** Preload applies a brief reverse pull before the opening cycle to relieve pressure from electric strikes or seals. **When to Use:** Enable this feature when door binding occurs at opening due to air pressure or locking systems that resist outward movement. **Notes and Tips:** - Adjust preload speed based on door size and sealing conditions. ### Reactive Mode Setting | **Index** | **Parameter** | **Description** | **Function Behavior / Effect of Adjustment** | **Value** | **Default** | | --- | --- | --- | --- | --- | --- | | 28 | Reactivate | 0 = No reactivation until fully closed, 1 = Allows reopening during closing, 2 = Touch-reverse on closing obstruction | Sets door behavior when a second open signal is received during the closing cycle. | 0-2 | 1 | **Introduction:** Reactive mode controls how the door responds when another open signal is received during the closing cycle. **When to Use:** Use this when quick response to motion sensors or push buttons is needed, especially in high-traffic areas. **Notes and Tips:** - Mode 2 (touch-reverse) is ideal for ADA compliance or safety-conscious environments. - Mode 0 should only be used in secured zones where reactivation must be ignored until fully closed. ### Quick Open Setting | **Index** | **Parameter** | **Description** | **Function Behavior / Effect of Adjustment** | **Value** | **Default** | | --- | --- | --- | --- | --- | --- | | 27 | Quick Open | 0 = Slow ramp from full closed, 1 = Standard ramp, 2 = Quick “kick-out” for fast opening | Sets acceleration profile from closed position. | 0-2 | 1 | **Introduction:** Quick open settings control how rapidly the door accelerates from a fully closed position. **When to Use:** Use higher quick-open levels in fast-paced environments (e.g., hospitals, logistics) requiring rapid access. **Notes and Tips:** - Avoid in quiet or residential settings due to increased motor noise. ### Door Resist Setting | **Index** | **Parameter** | **Description** | **Function Behavior / Effect of Adjustment** | **Value** | **Default** | | --- | --- | --- | --- | --- | --- | | 01 | Overload | Obstacle Detection Sensitivity | **Lower values increase** **sensitivity,** making the door stop or reverse more easily when resistance is detected during the opening cycle. **Higher values decrease sensitivity,** better handling **wind or pressure** but may delay obstacle detection. | 60-80 | 70 | | 26 | Easy Open | 0 = Heavy, 1 = Standard 15lbs, 2 = Light 5lbs | This refers to pounds of force needed to push the door manually. | 0-2 | 1 | **Introduction:** These parameters govern how the door responds to resistance and how easy it is to push manually when in standby. **When to Use:** Adjust based on user strength and environmental resistance (e.g., air seals, wind). **Notes and Tips:** - Higher Overload values reduce false positives in windy areas. - Lower Easy Open values may result in unwanted door activation by light touches. ## Related - [Parameter List & Descriptions](/parameter-list-descriptions-v10.md)
