Abstract
A system for grounding and diagnostics, including a conductive frame for mounting a capacitive sensor. In order to provide a means for ensuring and monitoring a grounded condition of a conductive frame, the system further includes a diagnostics circuit, by which the frame is AC grounded and which has an electric source connected to the frame via a first line and adapted to apply a diagnose signal to the frame via the first line, the diagnostics circuit being connected to the frame by a second line and being adapted to provide at least one quantity that depends on the diagnose signal and on a ground connection of the frame.
