ABSTRACT:
A signal generator for producing a control signal to control specific operations based upon the angular position of a rotating part in devices such as molding presses. An electrical signal related to the position of the rotating part is generated by using a potentiometer. The signal from the potentiometer is compared in a logic circuit to other adjustable electrical signals. Based upon the results of the comparison a control circuit provides the control signal. Furthermore, monitoring circuits are provided to detect any improper deviation in the electrical signals and upon detecting a deviation in an electrical signal the monitoring circuit provides an error output signal. An interrupter circuit is responsive to each monitoring device and disables the motion of the rotating part upon receipt of any error signal.
