Setpoint Ramp/Soak Programming And Operation; Overview - Honeywell DR4300 Product Manual

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.
