Example problems and solutions

PROBLEM: Length of a segment is unknown and depends solely on a trigger input for

conclusion.

SOLUTION: Enter the smallest interval possible, define a trigger for the subsequent

segment. The first condition for conclusion will be satisfied when the interval period

elapses but the next segment will not commence until the trigger occurs.

PROBLEM: Separate profiles have different setpoints, triggers and events but the basic

timing pattern is identical.

SOLUTION: Edit the common variables on one profile (perhaps on an unused profile),

copy that profile into each individual ramp and soak profile as a basic template and edit

specific details from there.
