Elevator Brake Release Automatic Control System
The brake release electrical control board is a very important element of the elevator rescue operation control system. The brake release board provides a power supply to operate an elevator brake by a battery in rescue operation mode to allow a motion of a car until the next floor level to release any passengers. The brake release board has some buttons to operate the car and some LED’s to indicate the state of running. There are also some parameters in the board to adjust the operation.
