Warning
・Never touch the power supply terminal while the power is supplied.
When the power supply terminal is touched, it gets an electric shock.
・Never touch relay output terminal and alarm output terminal when they
are connected with power supply.
Caution
・Use a round M3.5 press-fitting terminal.
・Use shielded wire and set the signal line (input, AO,
communication, etc.) as far away as possible from the
power line.
・Use the specified compensating lead wire for thermocouple input.
・Lifetime may be shortened if frequently operated for relay contact
output. Use auxiliary relay.
・Attach circuit breaker, switch, etc. on power supply wiring for safety and
clearly label that it is the power supply switch for this instrument.

［Reference］What is a group?
There are several “groups” classifying the items by kind on each screen.
Each group is given with a name that indicates the kind. Group name is
displayed on the upper display (except for SP or output display) on
Operation screen and on lower display in group display on Parameter

is  n：（n is a group number of 1 to 13）or ) is displayed, the
group can be changed by the dial as well. When the dial is turned
clockwise, the group changes in the same direction as the key, and in
the opposite direction as the key when it is turned counterclockwise.

5.3 Data Setting Procedure
Data is classified as “numeric data” and “character data.” Numeric value
blinks when change is enabled for numeric data, and the decimal point
blinks for character data. It is set up by the following procedure:
5.3.1 Numeric Data
Change in SP is shown as an example.
①The lowest numeric value blinks when the key is
pressed or dial is turned by 1 click, indicating that
change is enabled.
②The digit to be changed is selected by pressing the
key. Every time the key is pressed, blinking
value moves in order indicated by the arrow in figure
on the left. The blinking digit is subject for change.
However, value of other digit may be changed as well if
there is carrying/borrowing.
③The value of the subject digit to be changed is changed
by turning the dial. The desired value is set using the
keyordial.
④The value is registered by pressing the key. The
value blinking stops and the display returns to usual
display.
5.3.2 Character Data
Turning ON automatic turning is used as an example.
①The decimal point on the 4th digit blinks when the
key is pressed or the dial is turned for 1 click,
indicating that change is enabled.
②Desired data (character) is selected by turning the dial.
③The data (character) is registered by pressing the
key. Blinking of the decimal point stops.

[Caution]
If there is no key or dial operation for more than 10 seconds while
change is enabled, the value being changed is invalidated (original
value is recovered) and change is disabled.
[Reference] When

is displayed
If  is displayed when the key or dial is operated to enable
change, it means that the item cannot be set.  display
disappears in approximately 2 seconds and returns to the original display.

5.4 System Setup
The basic functions of this controller are as shown in the following table at
factory setting. To use with settings other than that of factory setting,
press the key for about 6 seconds to display the Setup screen and
then change on the specified displays. To change multiple items, change
in the order of the table below:
No. Item Screen
position
Factory setting
1 Input type Input list (page 17) SU1 K1
2 Use of square root (for mV, V, mA input) SU1 Not used
3Scaling SU1 -200 to 1370℃
4Output type (not required for dual output
specification) SU2 mA
5 Control mode SU2 PID
6 Control reverse/direct action SU2 Reverse action
☞
[Caution] Data initialization by change in basic functions
Please note that change in 1 to 6 of the previous page table initializes
other items (returning to the factory setting). Changed item and the
items initialized by it are shown as follows:
Changed item Initialized item
1: Input type All data except SU6 on Setup screen
2: Use of square
root
All data on Operation screen, all data on
Parameter screen except PA2 and PA12, sensor
correction, scaling, PV error upper and lower limit
3: Scaling (when
input is TC or
RTD)
SP, SP No., bias, emergency SP, and PA1 on
Parameter screen, and sensor correction
3: Scaling (when
input is mV, V,
mA)
SP, SP No., bias, emergency SP, up/down rate, all
data in CONT group on Operation screen (except
control RUN/STOP), all data on Parameter screen
except PA2 and PA12, sensor correction, PV error
upper and lower limit
4: Output type
5: Control mode
6: Reverse/direct
action
All data in CONT group on Operation screen
(except control RUN/STOP), all data in PA3 to 11
and PA13 on Parameter screen, PID mode, SP
No./PID No. selection, preset output, use of
present output, use of gapped control, use of
profiling
[Caution]
To change multiple items, be sure to follow the order of the No. The
changed data may be returned to the original factory setting if they are
not changed in order.
Ex.) If input type is changed after changing the control mode, the
control mode returns to the factory setting.
In such cases, check the data and change again if the data is factory
settin

[Caution] Initialization by changing alarm functions
When alarm function is changed, the alarm value, pause alarm,
hysteresis width and ON delays time for the changed DO No. are
initialized.
[Reference] Alarm type and functions
The types and functions of alarm equipped in this instrument are as
follows. Furthermore, the alarm occurrence conditions in the table
below are those for no pause alarm and 0 hysteresis width and 0 ON
delay time (pause alarm, hysteresis width, ON delay time Section
9.1):
Type Function (alarm occurrence condition)
Deviation high
alarm
When “deviation (SP – PV) > alarm setting
value”
Deviation low
alarm
When “deviation (SP – PV) < alarm setting
value”
Deviation absolute
value alarm
When “deviation (|SP – PV|) > alarm setting
value”
PV high alarm When “PV > alarm setting value”
PV low alarm When “PV < alarm setting value”
SP high alarm When “SP > alarm setting value”
SP low alarm When “SP < alarm setting value”
☞
[Caution]
・Set the functions of ALM (alarm) 1 to 4 and the alarm values at DO1
to DO4 of SU3, PA1.
・When the number of contact output points is 2 (standard), ALM3 and
ALM4 are not outputted. However, functions are available and setting
similar to ALM1 and 2 is possible. The status can be checked with
alarm/event display lamp.
[Reference] What is scaling width?
It indicates “scaling upper limit – scaling lower limit.
