2. Setting Target Setpoint (SP)
When the required value is displayed,
press the SET/ENTER key to register
the setpoint.
Show the SP Display (Operation Display).
(This is an example of setting the target
setpoint to 150.0).
Press the SET/ENTER key to start the
last digit of the setpoint blinking.
Blinking allows you to change the value.
To set the setpoint, use the
Left/Right arrow keys to move
between digits and the Up/Down
arrow keys to increase and
decrease the value.

3. Performing/Canceling Auto-tuning
Auto-tuningshouldbeperformedaftersettingatargetsetpoint.
Makesurethatthecontrollerisinautomaticmode(AUTO)andinrunmode(RUN)
before auto-tuning. For setting to AUTO, see “5. Switching between AUTO and
MAN,”andforsettingtoRUN,see“6.SwitchingbetweenRUNandSTOP.”
Ifthesetpointisknowninadvanceorauto-tuningdoesnotndanyappropriatePID
constants,setthePIDmanually.ForsettingthePIDmanually,seeUser’sManual.
CAUTION
Do not perform auto-tuning for the following processes.
Tune PID manually.
• Processes with fast response such as flow rate control and pres-
sure control.
• Processes which do not allow the output to be turned on and off
even temporarily.
• Processes which prohibit severe output changes at control
valves (or other actuators).
• Processes in which product quality can be adversely affected if
PV values fluctuate beyond their allowable ranges.
Show the Operation Display.
Hold down the PARAMETER key or PARA key for
3 seconds to display MODE menu.
Press the SET/ENTER key.
Press the SET/ENTER key.
Press the Down arrow key until the parameter AT appears.
The parameter AT (auto-tuning switch) is displayed.

specified, the parameter R.L
(REMOTE/LOCAL switch) is displayed.
Press the SET/ENTER key.

Press the Up/Down arrow keys to display the required setpoint.
Blinks during the change.
The setpoint has been registered.
This starts auto-tuning.
The limiter can be set to the output during auto-tuning.
For details, see User’s Manual.
The MAN lamp goes off, which means that
the auto-tuning completed normally.

The setting range is 1 to 4 (represent group numbers) or R.
To perform auto-tuning for the PID of group 1, set the parameter AT to 1.
To quit the auto-tuning, set the parameter to OFF.
During auto-tuning,
• The MAN lamp blinks.
• The OUT symbol appears.
• The output values at 100.0% and
0% appear alternately.
4. Selecting Target Setpoint Numbers (SPNO.)
Thefollowingoperatingprocedureshowsanexampleofchangingthetargetsetpoint
number(SPNO.)from1to2.EachSPhasitsPIDgroup.ThePIDgroupsetforthe

Show the Operation Display.
Hold down the PARAMETER key or PARA key for
3 seconds to display MODE menu.
Press the SET/ENTER key.
SPNO. has been changed to 2.
Blinks during the change.

Operation Guide
This operation guide describes key entries for operating the UT35A/UT32A.
Although the display of UT35A is used in this guide, UT32A can be operated similarly.
For operations using external contact inputs, see “DI” of “6. Terminal Wiring Diagrams”
in “Installation and Wiring.”
If you cannot remember how to carry out an operation during setting, press the
DISPLAY key or DISP key once. This brings you to the display (Operation Display) that
appears at power-on.
The scrolling guide is displayed on PV display in the Parameter Setting Display.
This guide can be turned on/off with the Fn key.

5. Switching between AUTO and MAN
AUTOandMANswitchingcanbeperformedusinganyofthefollowing:(1)A/Mkey,
(2)Contactinput,(3)Communication,and(4)Userfunctionkey.
ThegurebelowshowsadirectoperationusingtheA/Mkey.
WhenAUTO andMANswitchingfunction isassignedto thecontactinput,andthe
contactinputisON,theswitchingbykeyoperationcannotbeperformed.
Fordetails,seeUser’sManual.
MAN lamp is lit in MAN mode.
Each time you press the key,
AUTO and MAN is switched alternately.
WhenAUTOisswitchedintoMAN,thecontroloutputvalueinAUTOmodeisheld.
Thecontrollercanbeoperatedmanuallyfromtheholdvalue.
Ifthe manualpreset outputis set(MPONparameter≠OFF),thecontrollercanbe
operatedmanuallyfromthearbitraryoutputvalue(MPO1toMPO5parameters).
6. Switching between RUN and STOP
RUNandSTOPswitchingcanbeperformedusinganyofthefollowing:(1)Contact
input,(2)Parameter,(3)Communication,and(4)Userfunctionkey.
Thefollowingshowsanexampleofswitchingusingthecontactinput.
