segments.
For each segment setting, the pattern setting (Setting of set value and time) and other supplementary
functional setting (such as PID number, alarms, and time signal) are required.
Program setting
Pattern setting
(Set value and time
setting)
Supplementary function setting
(PID No., alarm, time signal, and
so on)
1) Pattern setting
• The pattern setting includes the setting of a set value and time for each segment.
• Segment “n” would be a segment to which the process will flow from the set value for
segment “n-1” to the set value for segment “n” at the time set for segment “n.”
Example 1) In the event of segment 2 (n=2) on the programming map (Pages 2 to 3):
A pattern in which the process will flow from 25°C (set value for segment 1) to
50°C (set value for segment 2) in 3:00 hours(time setting for segment 2). This is
called “ramp segment.”
Example 2) In the event of segment 3 (n=3) on the programming map (Pages 2 to 3):
A pattern in which the process will flow from 50 °C (set value for segment 2) to 50
°C (set value for segment 3) in 2:00 hours(time setting for segment 3).This is
called “soak segment.”
• The first segment will always be a soak segment, because of no set value for segment “n-1.”
Example 3) For segment 1 on the programming map (pages 2 to 3), the process will be soaked
for 1:00 hour (time setting for segment 1) at a temperature of 25 °C (set value for
segment 1).
2) Setting for other supplementary functions
The setting of some supplementary functions is made for each segment, while the setting of others
is made only for one in a pattern.
Parameters to be set for each segment
• Setting of PID group number
• Setting of alarms 1 to 2 (or 1 to 4)
• Setting of time signals 1 to 4 (or 1 to 6)
• Setting of guarantee soak
Parameter to be set only for one in a pattern
• PV start specification
• Cycle setting
• Setting of pattern link
For particulars of each setting, see an appropriate section for each parameter.

Explanation
A set value is established for the alarm to be generated in that segment. The
alarms are provided at two points (ALMl and ALM2) as a standard and,
optionally, it may be expanded to a total of four points (with additional points
ALM3 and ALM4).
For setting, engineering units are used. The setting range is 0 to 100% of the
input range.
Setting

2.3.3 Setting of time signal
Set value
Time
Explanation
A time setting is made for the time signal.
The time signal will function to turn on/off the digital output (open collector)
according to the program running. For this unit, 4-point or 6-point time signal
may be provided.
The time signal setting can be established by setting an ON time and OFF time
starting from the beginning of a segment to be set.
ON time
Time signal 1
OFF time
• The time may be set even beyond the segment. Where, however, a time is set
again in the later segment, the preceding time setting will be nullified and the
present time setting will be validated because one timer is provided for each
time signal.
• In one segment only one ON and one OFF setting are allowed for each time
signal.
• In the reset state the time signal outputs will be all OFF.
• The time signal timer will be stopped in the holding state.
• The time signal output immediately before the end of operation will be
retained when the unit operation is ended.

Explanation

Guarantee
soak
Setting
• This is a function to suspend the timer operation at the beginning of a
segment for waiting, where the Process variable fails to follow the
running program in the program control.
When the Process variable enters a specified zone, the timer operation
will start again.
• The waiting is performed only once at the beginning of the segment.
Therefore, the timer operation will not be suspended again after the
Process variable once enters the guarantee soak zone and leaves out of
the zone after starting the progress of time.
