2. Performing/Canceling Auto-tuning
Auto-tuning should be performed after setting a program pattern.
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 “4. Switching between RUN and RESET.”
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.
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.

Press the Down arrow key until the parameter AT appears.
The parameter AT (auto-tuning switch) is displayed.
Press the Up/Down arrow keys to display the required setpoint.
The setting range is 1 to 8 (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.
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.
During auto-tuning,
• The MAN lamp blinks.
• The OUT symbol appears.
• The output values at 100.0% and 0%
appear alternately.

3. Selecting Program Pattern Number (PT.No)
Program pattern number selection can be performed using any of the following: (1)
key, (2) Parameter, (3) Contact input, and (4) Communication.
The following shows an example of changing the program pattern number (PTNO.)
to 1 using the key.
Program pattern number can be selected when the controller is in a RESET mode.

Operation
Guide
This operation guide describes key entries for operating the UP55A.
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 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 MODE key.

4. Switching between RUN and RESET
RUN and RESET switching can be performed using any of the following: (1) key, (2)
Contact input, (3) Parameter, and (4) Communication.
The following shows an example of switching using the key.
For details of other switching methods and the display appearing when the operation
is started, see User’s Manual.

Program setpoint
Press RUN key for 1 s.
Symbol SSP
The number of segments included in the selected
program pattern.
The segment number for which operation is in progress.
The figure below is displayed while the right arrow key is held down.
Press RST key for 1 s.
When the controller is stopped, input and outputs are as follows:
PV input
Displays the PV value.
Control output
When the zone PID selection parameter (ZON) is set to segment
PID selection, the preset output value for the PID group number 1
is output. When the zone PID selection parameter (ZON) is set to
other than segment PID selection, the preset output value for the
PID group number for which zone control is performed is output.
Event output
Turns the output off in case of an event.
Alarm output
Turns the output on in case of an alarm.
5. Switching between AUTO and MAN
AUTO and MAN switching can be performed using any of the following: (1) MODE
key, (2) Contact input, (3) Contact input, and (4) Communication.
The following shows an example of switching using the MODE 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.
Displays ”MODE MAN” in AUTO mode.
Displays ”MODE AUTO” in MAN mode.

Press the SET/ENTER key.
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).
