Figure 3-8 Zone Configuration
See Figure 3-8. The zone filter adds or subtracts a given length from the
zone signal to effectively increase or decrease the length of parts. Use the
zone filter in the following ways.
Negative filter value: Part length is reduced by subtracting the filter value
from the leading edge. Use to prevent hanger detection (hanger skip). For
example, for hangers 1 inch wide, a − 1 inch zone filter reduces the hanger
width to zero, so the spray guns are not triggered on for the hangers.
Positive filter value: Part length is extended by adding the filter value to
the trailing edge. Use when coating small or narrow parts to prevent part
skipping and signal chattering. For example, for parts hung with a 1-inch
gap between the parts, a 1 inch filter value fills the gap so that the guns are
not triggered off between parts.
NOTE:
Appropriate lead and lag values should be set for each preset to
compensate for the effects of the zone filtering on gun triggering.
