    D-signal with respect to input and output voltage versus time:
    1 Hold-up time see section: Electrical Input Data.
    2 With output voltage monitoring, hold-up time th = 0.
    3 The signal will remain high if the D output is connected to
    an external source.
    4 tlow min = 100...170 ms, typically 130 ms.
