ABSTRACT:
Disclosed herein is an abnormal condition sensing monitor system for use in conjunction with machine tools, such as automatic press apparatus. Means for sensing an abnormal condition of the machine tool is provided in the vicinity of an essential portion of the machine tool.When a signal indicative of abnormal condition in outputted from the sensing means, a signal processing circuit is actuated. In response to an output obtained from the signal processing circuit, the operation of the machine tool is halted by means of a control circuit or the alarming device, such as lamp, buzzer, is actuated to warn the abnormal condition of the machine tool. Both the control circuit and the alarming device are connected to the signal processing circuit, and either of which are actuated depending upon a level of the signal obtained from the sensing means.
