When the blockage occurs, the controller will stop the crusher in the open/auto mode and reverse it to clear the obstacle. After the blockage is cleared, the controller will return to normal operation. If the blockage condition still exists, the controller automatically performs the inversion process within 30 seconds and can be performed three times. If the blockage still exists after three reversals, the controller will disconnect the motor and start the delay and abnormal status indicators.
