2-5 Startup Sequence Function
The inrush current may cause a voltage drop if all of the branch outputs are
connected simultaneously and there is little spare capacity in the power sup-
ply or the loads connected to the branch outputs are capacitive loads. A signif-
icant voltage drop may cause an output to be cut off. In this case, a time delay
can be applied between the connections of the branch outputs to minimize the
voltage drop.
Note (1) The time delay can be set between 0.0 and 99.9 s. (If the delay is set to
0.0 s, the startup sequence will not operate and the branch output will be
connected immediately.)
(2) The startup sequence is designed for the four branch outputs on one
S8AS. It does not provide time synchronization between outputs on more
than one S8AS.
After the power supply is turned ON and the self-diagnostics are performed,
the S8AS will start connecting the branch output according to their preset
startup sequence times.
