Start up: there is a signal warning of 10 seconds before the start-up; when the warning is over and the belt conveyor is allowed to start (the motor is only allowed to start when the power transmission capacity of the hydraulic coupling is the minimum); when the start-up, the motor shall be started one by one, with the time interval greater than the direct start-up time of the motor, generally greater than 3 seconds. Open the brake after the motor is fully started; after the brake band brake is opened in place, start to pull the coupling scoop bar (1 × and 2 × simultaneously) to the high position. The rotating speed of the belt conveyor gradually rises to the normal level; when the scoop bar is pulled to the high position, the signal of interlocking the next equipment will be output.
