3.2CREATING A PROGRAM

A program is created in two steps:

1.Define the segments of your program; the parameters used depend on what Program Mode has been configured - Rate Mode (see Subsection 3.2.2) or Time Mode (see Subsection 3.2.3). The segment definitions determine whether the selected segment is a Ramp Segment, a Soak Segment or an End Segment.

2.Set the required Program Options (see Subsection 3.2.4). These determine:

(i) The number of cycles performed by the program,

(Ii) The timebase to be used (hours/minutes or minutes/seconds) (Iii) The width of the Guaranteed Soak Band (if enabled),

(Iv) The state of the event indicator for each segment in the program,

(v)The lock code to be used for subsequent entries into Program Define Mode.

3.2.1Basic Guidelines

1.The Ramp/Soak Profile Controller may contain up to four programs.

2.Each program may comprise up to 16 segments.

3.Each segment may be:

(a)a Ramp Segment (setpoint changing at a defined rate or between the initial value and a pre-determined final value over a defined time),

(b)a Soak Segment (setpoint constant for a defined time,) or

(c)an End Segment (marking the end of the program).

4.A program may contain only one End Segment (the last segment in the program).

5.If the program comprises 16 segments, Segment 16 is automatically an End Segment.
