Digital Zone Triggering
See Figure 3-5. In this example, eight zone photoeyes are mounted so that
they create eight vertical zones within the booth. The guns are assigned to
the zones as follows for all three parts:
Gun to Zone Assignments
Guns Zones Guns Zones
1 1 5 2
2 3 6 4
3 5 7 6
4 7 8 8
See Figure 3-5:
Part 1 occupies all 8 zones, so all guns are triggered on.
Part 2 occupies only zones 1−4 so only the guns assigned to those zones
are triggered on.
Part 3 occupies only zones 5−8 so only the guns assigned to those zones
are triggered on.
NOTE: Part 3 is hung so that the hangers occupy zones 1−4. Normally,
this could trigger on the spray guns assigned to those zones. Use Zone
Filtering to prevent spray guns from triggering on hangers. Refer to Zone
Filter Configuration on page 3-11.

See Figure 3-6:
As Part 4 moves past the guns, all guns are turned on at the solid sections,
and turned off at the open section. Note that guns 1 and 8 stay on for the
length of the part.
