The door opening sensor provides a trigger signal to the control system. The control system sends a command to the inverter according to the current position of the fast rolling door, and starts the drive motor to make the door curtain rise quickly. Vehicles and pedestrians automatically descend through the rear door curtain and close the channel until the next door opening signal Open again. As the name implies, the lifting speed of the fast rolling door is very fast, and it cannot be directly started and stopped like a steel rolling gate. Generally, a frequency converter is required to control the speed of the motor.
The faster the rise, the better. When it is in place, there needs to be a deceleration buffer stop process to prevent impact on the track, prevent pinching and reduce noise. This is also a standard to measure the performance of the fast rolling door. But what should we pay attention to when using the fast door, especially when using it for the first time?
Precautions for the first time to use the fast door
1. When using for the first time, check whether the power supply voltage and phase match the rolling door, and ensure the correct operation direction of the fast rolling door.
2. Adjust the proper detection range of the Bluetooth reading head and the geomagnetic ring.
3. When there is strong wind or not in use for a long time, please raise the rolling door to the upper limit position and cut off the power supply.
4. Please do not stay under the rolling door to avoid accidental injury.
5. When there is no electricity, press the emergency stop switch to avoid sudden calls and injury by rolling the door.
6. Please do not scratch the curtain with a sharp instrument.
7. Wipe and test the photoelectric induction safety switch below the door post regularly with a clean cloth.
8, regularly with a clean cloth to wipe the rapid rolling door curtain, in order to keep the curtain clean (do not use neutral detergent to wipe the curtain).
Mechanical: The internal electrical contacts are large. Can be used directly as a switch to control the motor. This button box can be used as an ordinary shutter door can also be used as a fire shutter door.
Electronic lock box: can only be used as a fire shutter door, the internal contact is very small, the general current is very small. The line can be directly connected to the inside of the control box to control the fire shutter door.
When the main power is off, the battery starts to work and judges the undervoltage state of the battery at the same time. Once it drops below 21V, the alarm will be started and the delay will be started at the same time. After 30 seconds, the controller will automatically shut down the standby.
The fast door receives smoke and temperature sensing signals controlled by A. B .C three program methods to realize the separation of smoke and temperature sensing signals. All kinds of time are adjusted intelligently by microcomputer learning method. It has a high degree of intelligence.
