"Ground Faults" In a Data Center Environment

In digital circuits, a high impedance (also known as hi-Z, tri-stated, or floating) output is not being driven to any defined logic level by the output circuit. The signal is neither driven to a logical high nor low level; this third condition leads to the description "tri-stated". Such a signal can be seen as an open circuit (or "floating" wire) because connecting it to a low impedance circuit will not affect that circuit; it will instead itself be pulled to the same voltage as the actively driven output. The co… WebCheck for any problems with the conveyor, high-pressure unit, gantry and barfeeder. Make sure there are no blown fuses in the electrical cabinet.
