Ramp time or
rate segments
A ramp segment is the time it will take to change the setpoint
to the next setpoint value in the program.
Ramps are odd number segments (1, 3, . . . 11). Segment #1
will be the initial ramp time.
Ramp time is determined in either:
TIME* - Hours.Minutes Range = 0-99hr.59 min.
or
RATE* - EU/MIN or EU/HR Range = 0 to 999
* This selection of time or rate is made at prompt
“RAMPUNIT”.
Set this prompt before entering any Ramp values.
ATTENTION Entering “0” implies an immediate step change
in setpoint to the next soak.

Soak segments
A soak segment is a combination of soak setpoint (value) and
a soak duration (time).
• Soaks are even number segments (2, 4, . . . 12).
• 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:
TIME - Hours:Minutes Range = 0-99 hr:59 min.
SOAK DEV Guaranteed soak
All soak segments can have a deviation value of from 0 to ± 99
(specified by SOK DEV) which guarantees the deviation value
for that segment.
Guaranteed soak deviation values greater than zero
guarantee 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.
There are no guaranteed soaks whenever the deviation value
is configured to 0, (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 soak deviation value is the number in engineering units,
above or below the setpoint, outside of which the timer halts.
The range is 0 to ± 99.XX.
The decimal location here corresponds decimal configuration
chosen in the Display Set up group.
