Appendix C - Setpoint Ramp/Soak

Programming and Operation

C. Setpoint Ramp/Soak Programming and Operation

C.1 Overview

Introduction

As an option, the recorder can support the programming and execution of a setpoint program (profile). A total of twenty-four program segments are available, twelve ramp and twelve soak segments. In a ramp segment the setpoint value is changed as specified during configuration. The ramp is configured in terms of ramp time or ramp rate, depending on how you have configured the RPUNIT (ramp unit) parameter.

During a soak segment the setpoint is held at the specified value.

Odd-numbered segments are always ramp segments. Even-numbered segments are always soaks. These ramp and soak segments can be used in up to four programs. You designate the beginning and end segments to determine where the program will start or stop.

Every program must start with a ramp segment and end on a soak segment.

Recorder must be set to use SP1 (setpoint 1)

Only contiguous segments can be used by a program.

There can be overlap between programs. For example, Program 1 could use Segments 1, 2, 3, 4, 5, and 6. Program 2 could be configured to begin with Segment 5 and end with Segment 8.

This appendix contains instructions for setting up a setpoint program, and for executing the program at runtime.

Note that Section 4 contains instructions for using the single setpoint ramp supported by all DR4300 models. The SPRAMP (single setpoint ramp) parameter described in Section 4 must be set to DIS (disabled) if a setpoint program is to be used.

ATTENTION

If power is lost during execution of a program, upon power-up the recorder will use the last setpoint value prior to the beginning of the setpoint program. The program is placed in hold at the beginning. The Manual/Auto mode will be as configured under “PWR UP” in the “CONTROL” group.
