Precautions on wiring
Warning
Do not turn on the power until all wiring is complete in order to prevent an electric shock
or equipment failure.
★For inputs from a thermocouple, use the specified wires or compensating leads.
★For inputs from a resistance temperature detector, use wires that the wire resistance of leads is small and no resistance difference
is present among 3 wires (3-wire type).
★Provide input signal lines distant from power supply lines, power lines or load lines so as not to affect input signal lines with
noise induction.
★Wire the power supply for instruments such that they do not receive noises from the power supply for power devices.
The use of a noise filter is recommended in case that the equipment is vulnerable to noises.
Take care the following when a noise filter is used.
◎Install the noise filter as close to a temperature controller as possible.
Wire the instruments in as short a distance as possible to output lines (secondary side) of the noise filter and power
terminals for the temperature controller.
◎Isolate the noise filter input line (primary side) from its output line (secondary side).
High-frequency elements of noises may be induced, resulting in no provision of much noise attenuation effect as expected,
in case of input and output wires being close one another, such as being bundled together or installed in a same duct or
tube.
◎Wire the grounding wire of the noise filter in as short a distance as possible.
A long grounding wire is equivalent to insert of an inductance, resulting in deteriorated high-frequency characteristics.
◎Before installing the noise filter, peel off the paint applied on a mounting plate of the noise filter as appropriate, in order to
reduce the contact resistance between the noise filter and equipment housing.
★For the power supply, use and twist wires that cause less voltage drop.
★For the equipment being activated, it takes about 4 seconds after its power turns on. Use delay relays when using the
equipment for generating signals for interlocking circuits.
★The equipment is not attached with power supply switch fuses. Separately install fuses in proximity of the equipment, as
needed.
◎Recommended fuse rating: Rated voltage of 250 V and rated current of 1 A
★Use crimping terminals that match screw sizes.
◎Size of crimping terminal: Terminal width of 6 mm or smaller
Crimping terminal recommended
Manufacturer: NICHIFU
Model: ICTV-1.25Y-3N (Y terminal)
ICTV-1.25-3S (round terminal)
◎Tightening torque recommended: 0.5 N⋅m
◎Applicable wire
Use wires in sizes suitable for the terminals.

- 8 -
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.

- 9 -
4.4 Wait function
For the current step transferring to the next step, the next step does not begin if PV has not reached the wait zone
(similarly, if PV has overreached) after the step time elapsed.
However, if the wait time elapses, the next step begins at that point.
The above operation is executed by selecting 0 to 4 for each step, or by setting value for 1 to 4.
Selecting 0 indicates no function.
In the case of [the wait zone setting = 0], in-a- wait is effective until PV goes beyond SV.
Wait zone
Wait zone
Present step Next step
SV PV
In a wait
As PV enters into the wait zone, a transfer to
the next step is made.
Even if PV does not enter into the wait
zone, a transfer to the next step is
made when the wait time elapses.
4.5 Three-zone PID function
Numerical values of P, I, D and PC are switched over at each of the low, intermediate and high temperatures.
The ranges of the three zones are as follows:
- Low temperature (PID No. 1): SLL to intermediate point 1
- Intermediate temperature (PID No. 2): Intermediate point 1 to intermediate point 2
- High temperature (PID No. 3): Intermediate point 2 to SLH
4.6 Auto tuning function
Auto tuning starts at each of low, intermediate and high temperatures.
Auto tuning starts when the temperature at which the auto tuning is to be performed is set on each startup screen and the
RUN/STOP key is pressed or by an Auto tuning start command of the communication.
During the auto tuning, AT-1 (to 3) and SV are alternately displayed in the SV display digit ,andATALL and PV are
alternately displayed in the PV display digit.
Re-pressing the RUN/STOP key results in a stop of the auto tuning.
If the auto tuning has not terminated 3 hours after its start, an AT error is established and the run stops, displaying
“ERR2.”
Attempting an auto tuning during an automatic run results in first a temporary stop and then start of the auto tuning.
During a manual run, the auto tuning is not possible.
4.7 PV start/SV start
At a start of the program run after selecting the PV start and SV start, the start SV indicates the following:
PV start:
The run starts from the ramp step of upward slope in which the measurement temperature is included.
In addition, the run starts from the elapsed time, of which amount is assumed to elapse to come to the start point.
The calculation is made with the start point of 0°C /0 digit.
For below 0°C /0 digit, the calculation is made with the elapsed time of 0 minute.
SV start: The program run starts from the SV start temperature setting.

- 10 -
4.8 Time signal output
At starting each step, the time signals 1 to 4 are turned on upon elapse of the time set on the ON delay timer.
Then, the output is turned off upon elapse of the time set on the OFF delay timer.
During the time signal output ON, corresponding lamps of TS1 to TS4 light up.
Select the function selection among 0 to 5 of TS 1 to 4 at each step; if either one of 1 to 4 is selected, the above
operation is performed with the setting; if 0 is selected, no function is available; if 5 is selected, ON is always set
during the selection step.
If the time is set backward by using the or key, even after elapse of time, the output returns to the one
corresponding to the point at which the time set backward and time counting starts at that point, i.e., in the middle
of the way.
Example: If the elapsed time is returned by 5 minutes by using the key 3 minutes after the OFF delay
terminates, the output turns on and the OFF delay counts for 2 minutes.

4.10 In-a-run signal output/end signal output selection function
The use purpose of one relay output is selected from either in-a-run signal output or end signal output.
4.10.1 When selecting the in-a-run signal output
During a run, the relay output is always ON as in-a-run signal output.
4.10.2 When selecting the end signal output
At termination of the program run, the output as the end signal output is turned on or off according to the
following flow.
If the setting is above the maximum value within the setting range (“~~~~~” to be displayed), the output remains
turned on until the reset status described in Section 5.3.1 is established.

4.11 DI (external input)
Operation including run can be performed via DI through the external drive signal selection.
For the function of each DI, see Sections 4.10.1 to 4.10.4.
No operation is performed for [external drive signal = OFF].
4.11.1 Run/reset DI
The following operation is performed when ON continues for 2 seconds after the external contact open (OFF)
changes to the external contact closed (ON):
During a run: The run stops.
During a stop: A run starts.
4.11.2 Hold DI
The following operation is performed when ON continues for 2 seconds after the external contact open (OFF)
changes to the external contact closed (ON):
During a run: The run stops momentarily.
During a momentary stop: The run restarts.
4.11.3 Step feed DI

- 11 -
The step changes when the external contact open (OFF) changes to the external contact closed (ON) during a
program run.
4.11.4 Patterns 1 to 4 DI
A pattern is selected from 1 to 15, which are configured by combination of the external contacts 1 to 4 closed (ON)
and open (OFF).
No switchover of a pattern No. is possible during a run.
If all external contacts 1 to 4 are open (OFF), choose the pattern No. selected in the pattern No. setting mode.
Pattern 1 DI: 1
Pattern 2 DI: 2
Pattern 3 DI: 4
Pattern 4 DI: 8
Example: If both pattern 1DI and pattern 3DI are ON, selected pattern No. is: 1 + 4 = 5.
4.12 Auto run (AUTO)/manual run (MANU)
The base of a run is the auto run (AUTO); the auto run, however, changes to the manual run (MANU) by
holding the AUTO/MANU key pressed for 3 seconds.
No control is performed during a manual run, but the operation amount is output in a display.
The displayed operation amount is identical to the SV displayed in the lower row on the PV/SV screen in the
normal mode.
Pressing the /key in this status results in a change of the operation amount to be output.
The operation amount and step time are as follows at the start of a manual run:
−Operation amount
In the case of in-a-stop: Starts with the operation amount of 0.0%.
In the case of in-a-run: Starts with the operation amount at the time of switchover
−Step time
In the case of in-a-stop: Remains in a stop (no step time counting begins).
In the case of in-a-run: The step time elapses (remains in a stop during a momentary stop).
Re-holding the AUTO/MANU key pressed for 3 seconds results in a return to the auto run.
The AUTO and MANU lamps lights up as follows:
During an auto run: The AUTO lamp turns on and the MANU lamp turns off.
During a manual run: The AUTO lamp turns off and the MANU lamp turns on.
The output interval during a manual run is fixed to 10 seconds.
4.13 Operation amount limiter
By using the operation amount function selection, “no limit function” can be set or two types of operation
amount limiters can be effective.
In addition, two types of limiters can be effective by using the other operation amounts limiter setting described
in Section 4.13.3.
4.13.1 Operation amount limiter
The operation amount is limited by using the primary/secondary control operation amount upper limiters and
Primary/secondary control operation amount lower limiters selected by the operation amount limiter function
selection at each step.
If the operation amount limiter function selection is 0, then 0.0 to 100.0 % is applicable.

- 12 -
4.13.2 Operation amount current limiter
The operation amount and current value are limited at each point obtained by dividing SLL to SLH into 10.
At the operation amount limiter points 1 to 11, the operation amount resulted from calculation is limited.
At the current value limiter points 1 to 11, the operation amount is limited by the operation amount at the
current value limiter point determined from a measured current value and present operation amount if the
measured current value at each point exceeds the value [setting value - current limiter sensitivity].
This operation amount changes each time when measuring the current value.
The final operation amount is limited by using either smaller limit of the above two.
The function is effective when [OUT 2 selection = 4 to 20mA], CT existent, [CNT = 1] and operation amount
current limiter effective. OUT2 outputs MV1 (equivalent to OUT1).

Example:
Assume the following for various settings and PV:
PV = 120 °C, operation amount limiter point 2 = 75.0%, current value limiter point 2 = 10.0 A, present operation
amount = 60.0% and AHC = 1.0 A.
−If measured current valued = 15 A:
Based on the relation [0 to present operation amount (60.0%) = 0.0 to measured current value (15.0 A)], the
operation amount [current value limiter point 2 (10.0 A) - current limiter sensitivity (1.0 A)] is to be determined.
The calculation results in the operation amount of 36.0%.

4.16 PV filter setting
4.16.1 PV filter setting
This setting is a function to achieve the CR filter effect on the software by performing a primary delay
calculation on the PV of the input 1.
The filter effect is set with the damping time constant [t].
(Damping time constant is defined as time when PV reaches about 63% in a stepwise change of input.)
* CR filter: Filter of first order lag
Application of a PV filter:
(1) By elimination of high-frequency noise, effect of noise is mitigated when electric noise applies to input.
(2) Response can be delayed for an abrupt change of input.

4.16.2 B thermocouple/PR40-20 special PV filter setting
This setting is a function for the input 1 to add the PV filter setting time further with a limitation of a particular
range on the B thermocouple and PR40-20.
Filter effect is set by the damping time constant [t].
The effective range of the set filter is as follows:
(1) B thermocouple: In the case of 400°C or below
(2) PR40-20: In the case of below 800°C

4.17 Event alarm
By setting the events 1 to 4 function setting, outputs of EV 1 to 4 are turned on if PV is located within the alarm range.
Corresponding EV1 to EV4 lamps light up.
By switching over the events 1 to 4 polarities, selection of open/closed is possible at the turn-on.
Output is also turned on at occurrence of a loop abnormality when the events 1 to 4 function 2 setting is effective.
* For loop abnormality, see Section 8.17 “ Loop abnormality.”
The setting can be released by using the key or reset DI, provided that the following condition is met:
(1) Normal status at the release
(2) Standby existent even if abnormality status at the release
Judgment process is performed only during a run (no judgment made during a stop).
Restoration from a power outage is made for the status previous to the outage.
4.18 Loop abnormality
When the primary/secondary control loop abnormality PV change amount setting is not 0, the PV change amount is
determined every loop abnormality time setting time if the present step is a soak.
Consequently, “loop abnormality” occurs if the following condition is met: ⊿PV ≤Primary/secondary control loop
abnormality PV change amount setting.
Function OFF is established if the primary/secondary control loop abnormality PV change amount setting is 0.

4.20 Electric Power Outage Function
−Upon recovery of the electric power after its outage during a run, the status at the time of the outage is restored
under the following conditions. Note that, if the PV at restoration is out of the range of [PV ±electric power
outage restoration temperature width], the restoration is made as a stop.
−Alarm statuses of the event function are also restored.
1) If the step 1 is in the status of a timer run (SV=SLL):
→Restored at the location at the time of the outage.
2) In the case of in-a-ramp of SV increase or in-a-soak:
→Restored with the PV start.
Restored with the run end “END” if no SV present.
3) In the case of in-a-ramp of a SV decrease or in-a-soak after the decrease:
→Restored with the PV start at the step of the decrease if PV >decrease point.
Restored with the run end “END” if PV ≤decrease point.
4) In the case of in-“END”:
→Restored to “END.”
5) Restored with a temporary stop for the items 1 through 3 if a power outage occurs during a temporary stop.
6) In the case of in-a-manual-run:
→Restored with a stop status.
