4.21 Setpoint Ramp/Soak Programming

Introduction

The term “programming” is used here to identify the process for selecting and entering the individual ramp and soak segment data needed to generate the required setpoint versus time profile (also called a program).

A segment is a ramp or soak function which together make up a setpoint program. Setpoint Ramp/Soak Programming lets you configure six ramp and six soak segments to be stored for use as one program or several small programs. You designate the beginning and end segments to determine where the program is to start and stop.

Review program data and configuration

While the procedure for programming is straightforward, and aided by prompts, we suggest you read “Program Contents”. Table 4-25lists the program contents and an explanation of each to aid you in configuration. Then refer to Subsection 3.5 – Configuration to do the setpoint program.

Make sure SPRATE and SPRAMP are disabled.

Fill out the worksheet

Refer to the example in Figure 4-3and draw a Ramp/Soak Profile on the worksheet provided (Figure 4-4)and fill in the information for each segment. This will give you a record of how the program was developed.

Operation

Refer to Table 4-26Run/Monitor the program.

Program Contents

Table 4-25lists all the program contents and a description of each.

	Table 4-25 Program Contents
Contents	Definition
Ramp time or rate	A ramp segment is the time or rate of change it takes to change the setpoint
segments	to the next setpoint value in the program.

•Ramps are odd number segments. Segment #1 will be the initial ramp time.

•Ramp time is determined in either:

TIME* - Hours:Minutes	Range = 0-99 hr.:59 min.
or

EU-M* - Degrees/Minute Range = 0 to 999

EU-H* - Degrees/Hour

*The selection of time or rate is made at prompt “RP UNIT” - Set this prompt before entering any Ramp information.
