13   electronic control system
(1) the system is adopted as Siemens DC Governor System to drive motor, slitting machine and recoiling reel. Based on the speed signal on disk shear, compared with dragging and winding speed, speeds of both machines can be basically kept in Synchronization. Adjustable Tension may balance the rewinding and dragging. Manual adjust can be involved during the process.
(2) Two working ways, single unit adjustment and complete machine linkage. single unit adjustment is mainly used to make strips ready, which is preparation for the linkage. During the linkage, adjustment is decided by one potentiometer, manual adjustment can be involved for each unit, and the linkage may be stopped at any time when necessary by pressing stop button. The linkage will stop automatically if there is anything abnormal.
(3) The system consists of control cabinet, main operating penal  and two assisting operating panels.
(4) the system is adopted as Siemens DC Governor System, and various logic control are through PLC to realize operation and control.
