3. Quick Setting Function (Setting of Input and Output)
The Quick setting function is a function to easily set the basic function of the control-
ler.
Turn on the controller to start the Quick setting function.
This function allows you to easily set the control type, input, and output, and quickly
start the control action.
The items (parameters) to be set by Quick setting function are as follows.
(1) Control type (PID control, Heating/cooling control, etc.)
(2) Input function (PV input type, range, scale (at voltage input), etc.)
(3) Output function (control output type and cycle time)
After turning on the controller, first decide whether or not to use the Quick setting func-
tion.
Operation in Initial Display
· Press the SET/ENTER key while YES is displayed to start the Quick setting function.
· If you change YES to NO and press the SET/ENTER key, Operation Display will
appear without starting the Quick setting function.
Operation for Setting
· To select the parameter setting displayed as the initial value, press the Down arrow
key to move to the next parameter.

Operation Guide
This operation guide describes basic settings and operations of the UT35A/UT32A.
For details of each function, see the electronic manual.
The scrolling guide is displayed on PV display in the Parameter Setting Display.
This guide can be turned on/off with the Fn key.
· To change and set the parameter setting, press the SET/ENTER key to start the
setpoint blinking. The blinking state allows you to make changes (setting mode).
Use the Up/Down/Left/Right arrow keys to change the setpoint. Press the SET/EN-
TER key to register the setting.

Making Settings Using Quick Setting Function
Example: Setting to PID control, thermocouple type K (range of 0.0 to
500.0
0
C), and current control output
For the detailed procedure and switching of displays, see "Flow of Quick Setting
Function" below. For the parameters to set, see the next page.
(1) Press the SET/ENTER key while YES for QSM (Quick setting mode) is displayed.
(2) Set the control type parameter (CNT) to PID (PID control).
(3) Set the PV input type parameter (IN) to K1 (-270.0 to 1370.0
0
C).
(4) Set the PV input unit parameter (UNIT) to C (Degree Celsius).
(5) Set the maximum value of PV input range parameter (RH) to 500.0.
(6) Set the minimum value of PV input range parameter (RL) to 0.0.
(7) Set the output type selection parameter (OT) to OUT terminals (current=00.02).
(8) Finally, EXIT is displayed. Change NO to YES and press the SET/ENTER key to
complete the setup. Operation Display appears.
Press the SET/ENTER key while YES
is displayed to start the Quick setting.
