Title: Punching or stamping machine safety circuit - uses similar duplicate circuits connected to exclusive=OR logic
Inventor: SCHNEIDER FRANZ ING GRAD
IPC: G05B9/03
Filed: 1977-09-28
Abstract: The press safety system is designed so that double circuit known type safety control circuits are mounted exterior to a control unit. This arrangement provides intrinsic security to connections used for transmitting orders to the control unit, as well as output stages and their circuits. The two circuits of the safety control system are equipped with the same components in a control unit. The connections transmitting orders to the controlling unit are connected in similar fashion to an EXCLUSIVE-OR circuit. Because of the safety circuit connection interruptions or bad contacts outside the controlling unit can only eliminate its own safety circuit. Thus the system cannot be made ineffective because the circuit will immediately detect such faults and short circuit the supply input.
