ABSTRACT:
The safety interlock prevents the starting of a device if one or more safety switches is not first cycled through its operational cycle. Since the safety switches must be operated before starting, the device will not operate if the switches have been tampered with or have failed. The interlock includes a digital memory unit connected to the switch which stores information indicative of the cycling of the switch. The output of the memory unit is interconnected with the starting system of the device such that starting is prevented unless the stored information indicates that each switch has been cycled. In a preferrred embodiment the interlock includes a microprocessor.
