The use of shielded wires is recommended.
For Pt100 (resistance temperature detector), use identical wires of low lead resistance and no resistance difference among
3 wires.
4. Terms and Various Functions
4.1 Program run
* The following number of steps is fixedly set, depending on the number of patterns.
Pattern No. 1 2 3 4 5 6 7 8
Step No. 99 49 33 24 19 16 14 12
Pattern No. 9 10 11 12 13 14 15
Step No. 11 9 9 8 7 7 6
To make control, SV is changed parallel to the temperature and time set for each pattern.
If a setting is made to the lower limit within [a setting range - 1] (“----” to be displayed) in the temperature setting for
each step, steps following the said step is ineffective and no setting parameter is displayed.
The pattern run ends at one step prior to the step set as “----.”
Neither the step temperature nor the step time in a run can be changed.
If the setting temperature of the step 1 is set at SLL for a PV start, the time of step 1 is effective and a timer run begins.
(The normal PV start begins with the step 2.)
“TIME” is displayed in the SV display frame.
If the setting temperature for all steps is 0, setting a temperature for a step results in the next step automatically being set
to the same temperature (only at key operation).
If the step time is set above the upper limit within the setting range (“~~~~~” to be displayed), the step continuously runs
at the setting temperature.
Each pattern repeats for the number of times that has been executed. When the setting is set to “0”, it will continue to
repeat until it is stopped with key operation. (max. 9999 times)
During a run, the TIME output is ON.
For display during the program run, see Section 5.3.2 “Auto run (normal mode).”
The following is displayed upon termination of the program.

• The screen shown in the left is the normal one.
4.2 Step feed/step return
Holding the “” key pressed for 3 seconds during a run results in the step feed to transfer to the next step.
Holding the “” key pressed for 3 seconds results in the step return to transfer to the step one previous to the current
step.
In the case of the external drive signal selection being ON, the step feed is executed when open of the step feed DI
changes to closed.
Only the timer is reset when the step return is executed at step 1 (or the leading step).
If the step feed is executed at the step for the endless setting, END is established.
*When the External Drive Signal Selection is set to ON, Step Forward/Reverse with key operation will not be
effective.
4.3 Elapsed time increase/decrease
During a program run, pressing the / key on the elapsed time screen results in an increase/decrease of the elapsed
time.
The unit of the elapsed time is minute. Counting the number of seconds continues.
The change range of the elapsed time is 0 to [the setting time in a run - 1].
The change range of the elapsed time for a wait zone is 0 to [the setting time in a run + the wait time - 1].
Execution of an increase/decrease in the wait zone results in an increase/decrease of the elapsed time; however, setting
the elapsed time below the setting time results in a return to the normal step run but not to the wait zone.
This function is ineffective for an end signal.
