Analog Zone Triggering
See Figure 3-7. Analog scanners read from top down and from bottom up.
The iControl system uses the top-down analog signal for zone detection and
the bottom up signal for reciprocator control. Each zone is measured from
the top of the scanner, so a part automatically occupies all the zones from
the bottom edge of the part to the top of the scanner.
The disadvantage of using an analog scanner for zone triggering is that a
low hung part will cause all the guns assigned to the zones above the top
edge of the part to be triggered on.
To avoid triggering on the guns above the top edge of the part, create a
spray preset for the part with the zones set to zero for those guns.
This drawback also means that the guns in front of an open area of a part
will not be triggered off, but will continue to spray.
