•  SP Display

  Displays the measured input value on PV display. 

  Displays the target setpoint (SP) on Setpoint display (SP can be changed).

•  OUT Display

  Displays the measured input value on PV display.

  Displays the control output value (OUT) on Setpoint display (OUT can be changed 

in manual mode).

After showing the OUT Display, press the DISP key to show the following displays 

conditionally.

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 find any appropriate PID 

constants, set the PID manually. For setting the PID manually, see User’s Manual (IM 

05P01F31-01EN).

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.

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 (IM 05P01F31-01EN). 

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.

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 

parameter PIDN (PID number selection) is used.

Operation Guide

This operation guide describes key entries for operating the UT32A.

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 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) Communication, and (3) User function key.

The figure below shows a direct operation using the A/M key. 

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) Parame-

ter, (2) Communication, and (3) User function key.

For details of other switching methods and the display appearing when the operation 

is started, see User’s Manual (IM 05P01F31-01EN).

When the controller is stopped, input and outputs are as follows:

PV input

Displays the PV value.

Control output

Displays the preset output value.

The preset output value is set for each PID group. 

Alarm output

Turns the output on in case of an alarm.
