Definition:

A change from one in.terval to the other: either a change from a delay to

a duration or from a duration to a delay. The combination of delays and

durations makes up a transition sequence (Figure 4.2).

Decision

Factors:

• number

transitions - dependent upon number of delays and

durations

• delays - lengths of spaces between beads

• durations - material bead lengths

• transition set-points - cumulative sum of delay and duration values

The placement

every bead

material on the substrate requires at

least two time intervals to be completed: one delay (gun off) followed

one duration (gun on).

NOTE: Nordson timers commonly use the first pattern interval as a

delay. In Figure 4.2, the pattern consists

a delay, a duration, a

second delay, and a second duration. Each new pattern starts with the

first delay interval.

The

PC40 allows you

program from one to four delays and from one

to four durations.
