Abstract

A safety device for the automatic monitoring of a running machine comprises a first signal transmitter (1), which is controllable by a moving machine component and/or moving work pieces and emits a first signal. A member (2) is connected to receive the said first signal and is responsive to an unacceptable change in duration and/or frequency of the said first signal to provide a failure signal. A manually activatable second signal transmitter (7) is connected to the member (2) for transmitting thereto a second signal simulating the said first signal. A switching member (3) is connected to the member (2) and has a timer (4) and a switch (5), the switching member serving to produce an output signal during the presence of a failure signal coming from the member (2) and upon completion of the time predetermined by the timer (4). <IMAGE>
