When the elevator is working in the normal operation, the unit is in the monitoring state to track the operation of the elevator, the abnormality such as power failure, shortage, etc., causing the elevator to operate normally, EBD puts work in three seconds.
The RBD monitoring and the emergency rescue process are automated under microcomputer control, no need for human intervention.
Electrical interlock automatic feedback, the elevator main power supply does not need to be stringed. The control conversion between the device and the power supply is fully isolated, ensuring the normal operation of the elevator and the signal acquisition in the emergency process, safe operation during the rescue process; during the elevator maintenance process, the unit refuses to put into work.
All digital working mode, changes in ambient temperature do not affect the performance of the device. The three-phase reactive power supply system supplies the power supply of the elevator leader using the (SPWM) sinusoidal wave width modulation method, and the TOSHIBA power drive module is used as power output, so that the elevator emergency start, run, stop more smooth and comfortable, noise.
See the previously running parameters and fault memory through self-test, promptly knowing the location of the fault, convenient for fault diagnosis and maintenance.
With a simple applicable interface circuit, it is convenient for on-site installation and commissioning; there is no special "online" and "offline" socket, when suspected that the emergency device has faults affect the normal operation of the elevator, there is no need to disconnect the wiring, and On the Internet ", it is changed to" offline "state, and the emergency device is completely detached from the circuit control system.
The battery is charged and discharged, overcomes the battery self-discharge characteristics, and does not need to be charged and discharge and other maintenance of the battery, which greatly improves the battery life.
