Title:
【発明の名称】スタツドテンシヨニング装置の群制御装置
Document Type and Number:
Japanese Patent JPS6047072
Kind Code:
B2
Abstract:
An apparatus for automating the operation of a plurality of stud tensioning devices. A central control unit outputs a sequence of control signals, each of the control signals indicating an operative step to be completed by the stud tensioning devices. The next control signal is not sent out until a signal is produced which indicates that each of the stud tensioning devices have completed the preceding operative step. When the automatic operation is not continued due to break-down and undue slow-down in the operation of one of the devices, the automatic operation is temporarily interrupted, and the manually-operated switch is activated to return the mode to the automatic operation. Alternately, the other normal devices are automatically operated and thereafter, the malfunctioning device may only be examined.
