This is the 4th step in defining a NEMA control using the VS
NEMA Wizard.
Having
defined phases and overlaps, the phasing sequence can be shown. There is not
much to define, but to check if the resulting phase patterns correspond to what
was intended.
- On the upper
half of the panel, each half ring can be set to lead or lag. At the same time
the pattern resulting of the leading standard NEMA phase and all phases added to
it as overlaps can be seen.
- On the lower
half of the panel the resulting phase patterns are shown. The sequence is read
from left to right. If two possibilities are shown one above another, the
controller might choose which one to use, according to the traffic situation.
