DELAY ADJUSTMENT OF THE CONTROL SIGNAL (SUS-D)
1 Measure the pulse width of the SUS-D signal. 2 Check the pulse width of the SUS-D input signal (gate terminal of Q2112). Adjust the variable control so that the pulse width of the SUS-D input signal (gate terminal of Q2112) becomes the same pulse width ± 5 nsec as the SUS-D signal. Note: For details on measuring points of waveform, see the figure below.

SUS-D pulse width Tsus - Dg

C

50 % of the crest value SUS-D signal (input to the gate terminal of Q2112)

50 % of the crest value

D

SUS-D pulse width: Tsus - Dg Adjust so that "Tsus - Dg = Tsus - D ± 5 nsec," using the variable control shown in the table below:
