A soak segment is a combination of soak setpoint (value) and
a soak duration (time).
• Soaks are even number segments (2, 4, . . . 20).
• Segment 2 will be the initial soak value and soak time.
• The soak setpoint range value must be within the setpoint
high and low range limits in engineering units.
• Soak time is the duration of the soak and is determined in:
These prompts will appear only when the number of PID sets
selected in the Control or Control 2 Setup Group is set to
4KEYBD. Each Ramp and Soak segment may select a specific
PID set. A Setpoint Program enabled only for Loop 1 will use
Loop 1 PID Sets. A Setpoint Program enabled only for Loop 2
will use Loop 2 PID Sets. A Setpoint Program enabled for both
Loop 1 and Loop 2 will use Loop 1 PID Sets.
Each individual soak segment can have a unique guaranteed
deviation value of from 0.000 to ±99.99 in engineering units.
Guaranteed Soak deviation values greater than zero ensure
that the soak segment's process variable is within the ±
deviation value for the configured soak time. Whenever the ±
deviation value is exceeded, the soak timer stops until the
process variable gets within the ± deviation value. While the
soak timer is halted, "R" and "H" will alternate in the upper
display. When the PV gets within the ± deviation value, the
timer will resume and a steady "R" will appear in the upper
display.
There are no guaranteed soaks whenever the deviation value
is configured to 0.00 (that is, soak segments start timing soak
duration as soon as the soak setpoint is first reached,
regardless of where the process variable remains relative to
the soak segment).
The decimal location used here corresponds decimal
configuration chosen in the Display Set up group.
