Interlock Detector with Self-Diagnosis Function for an Interlock Circuit, and Method for the Self-Diagnosis of the Interlock Detector

摘要

The interlock detector includes a first input, wherein a first output signal from an interlock generator is applied to the first input. The interlock detector further includes a second output which is configured to provide a microprocessor with a second output signal. The interlock detector further includes a differential amplifier that includes a second input, a third input, and a third output, wherein the second input and the third input are connected to the first input. The interlock detector further includes a comparator circuit that includes a fourth input and a fourth output, wherein the fourth input is connected to the third output, the fourth output is connected to the second output, and the fourth input is positioned between the comparator circuit and the differential amplifier.
