At S4A Industrial Co., Limited, we prioritize not only providing high-quality access control hardware but also ensuring our global partners have the technical support needed for a perfect installation.
Recently, one of our valued clients encountered a common installation challenge with theS4A ED100 Automatic Door Opener. After the initial setup, the door was opening with too much force and slamming against the adjacent wall. This is a representative issue that can occur when the default factory settings do not match the specific physical constraints of the installation site.Here is how S4A guides customers to solve this problem to ensure smooth, safe, and professional door operation.
The Problem: Door Over-travel and Wall Impact
When an automatic swing door slams into a wall, it can cause structural damage to the glass, hinges, or the motor itself. This typically happens because theopening angleis set too wide for the space or thebackcheck speed(the slowing down phase) is not properly calibrated.
The S4A Solution: 2-Step Technical Adjustment
This is a 90° swing door operator. To adjust the opening angle and prevent the door from hitting the wall, you only need to move the mechanical stop block on the sliding rail to the right.
By adjusting the position of this sliding rail stop block, you can limit the maximum opening angle of the door, making it open smaller and softer, so it will no longer bump against the wall.
