1.急停按钮

1. Emergency stop button

按下紧急停止按钮时，一对触点断开窗帘所需的机电设备，另一对触点进入PLC，断开PLC控制的机电设备的启动电路。

When the emergency stop button is pressed, one pair of contacts disconnect the mechanical and electrical equipment required for the curtain, while the other pair of contacts enter the PLC and disconnect the starting circuit of the mechanical and electrical equipment controlled by the PLC.

2.底部气囊设备

2. Bottom airbag equipment

由接收设备和发射设备组成，发射设备控制气压开关和发射电路，安装气囊底部密封触发气压开关在门窗帘下。当门体下降时，如果有人或障碍物，快速门感觉立即停止向下降，自动和反向运行上升到顶部。移动物体侧门感觉自动降低，手动自动有效，确保人和车辆的交通。

Consisting of a receiving device and a transmitting device, the transmitting device controls the air pressure switch and transmission circuit, and installs a safety airbag bottom sealed trigger air pressure switch under the door and window curtains. When the door body descends, if there are people or obstacles, the quick door feels like it immediately stops descending, automatically and in reverse running up to the top. The side door of the moving object feels automatically lowered, and manual operation is effective to ensure traffic safety for both people and vehicles.

3.光电保护装置

3. Optoelectronic protection device

快门选择反射光电开关时，两侧门柱安装感应范围为0-5米（适用于超过5米范围），高度为30-40厘米。当门扇运行自动下降时，有人或物体阻挡传感器，门感觉立即停止下降，自动上升到顶部。当物体被移动时，门体会自动降低到底部。它在自动手动时是有效的。

When selecting the reflective photoelectric switch for the shutter, the sensing range of the two door pillars installed on both sides is 0-5 meters (applicable to a range exceeding 5 meters), and the height is 30-40 centimeters. When the door leaf automatically descends and someone or an object obstructs the sensor, the door immediately stops descending and automatically rises to the top. When an object is moved, the door will automatically lower to the bottom. It is effective in automatic and manual mode.

4.光幕设备

4. Safety light curtain equipment

快门的光幕设备适用于使用频率较高的公司，因为该装置的接触面会比光电大得多。门套两侧的光幕照射感应光源，只要触发到任何一个，快门就会立即停止运行，立即上升，性相对较高。

The safety light curtain device of the shutter is suitable for companies with higher usage frequency, as the contact surface of the device will be much larger than the safety photoelectric. The light curtains on both sides of the door frame illuminate the induction light source. As soon as any one is triggered, the shutter will immediately stop running and rise, with relatively high safety.
