What are the steps and precautions for the quick rolling shutter door of salt field equipment

Description :

    There are two ways to locate the quick rolling shutter door: mechanical positioning. This positioning method is similar to steel rolling shutter doors, with the advantage of fast speed and low controller requirements. Rotary encoder positioning: The elevators we often ride on use rotary encoders for positioning. The advantage of this method is accurate positioning. Taking an encoder with a resolution of 1024 as an example, a 3-meter-high door is divided into nearly 9000 points, and theoretically the degree can reach 0.3mm. The height setting is simple.

    Due to the wide variety of fast rolling shutter doors, PLC automatic control is mainly used for translating fast rolling shutter doors. Required functional components: photoelectric detection switch, limit switch, overload protection switch, DC motor.

When someone approaches the fast rolling shutter door and passes through the photoelectric detection switch, there is current flowing through the switch. Due to the normally closed door limit switch, the coil is energized and the motor rotates forward. When the door leaf reaches the designated position, the coil loses power and the motor stops operating.

When the fast rolling shutter door leaf reaches the designated position, start the delay timer. After 8 seconds, the door will automatically enter the closing process and the motor will reverse. When the door leaf moves to the closed limit position, the switch is normally open, the coil loses power, and the motor automatically stops operating.

3. During the closing process, if someone approaches the fast rolling shutter door, the closing procedure should be immediately stopped and the opening procedure should be automatically entered. What are the steps and precautions for the quick rolling shutter door of salt field equipment

4. Within the 8-second waiting time after the door leaf is opened, if someone approaches the fast rolling shutter door, a delay of 8 seconds must be restarted before automatically entering the closing process to ensure safe passage through the fast rolling shutter door.

5. Considering that the automatic control system of the fast rolling shutter door may fail during the period of malfunction and maintenance, it is necessary to add a manual door opening and closing switch.
