Intelligent high voltage interlock loop with individualized detection of connector connectivity

An apparatus to inform a manufacturing system about proper installation of high voltage components using a high voltage interlock loop, the apparatus comprising:

• one or more computer readable storage media;
• a processing system operatively coupled with the one or more computer readable storage media;
• and program instructions stored on the one or more computer readable storage media that, when read and executed by the processing system, direct the apparatus to:
• receive a signal from a detector connected to the high voltage interlock loop after a second-jumper current source, wherein:a loop current source is configured to transmit a loop current for the high voltage interlock loop;a first-jumper current source is connected to the high voltage interlock loop in parallel with a first jumper of a first high voltage connector and the first-jumper current source is configured to transmit a first jumper current lower than the loop current;the second-jumper current source connected to the high voltage interlock loop after the first-jumper current source, in parallel with a second jumper of a second high voltage connector, and the second-jumper current source is configured to transmit a second jumper current lower than the first jumper current;
• andthe detector configured to determine connectivity of the first high voltage connector and the second high voltage connector based on whether the loop current, the first jumper current, or the second jumper current is received by the detector, and transmits the signal indicating the connectivity;
• andin response to the signal, notifying the manufacturing system about the connectivity.
