Monitoring device for checking position-dependent sensing signals - determines reference marker signal rising and falling edge positions with respect to predefined positions of mutually phase shifted sensing signals and indicates whether edges lie within predefined positions

摘要

The device comprises an arrangement for determining the positions of the rising and falling edges of a reference marker signal (SR) relative to predefined positions of mutually phase shifted sensing signals (S1,S2). A display (8) indicates whether the rising edge is show within a predefined position and distinguishably indicates whether the falling edge lies within a further predefined position. The reference marker positions are shown as bars (13), one end corresp. to the rising edge and the other to the falling edge.
