the ģ key.
5-4. Auto return function
If no key operation is conducted for 3 minutes on the various screens (with the exception of the “0-2 Output monitoring
screen,” “0-3 Execution step No. monitoring screen,” “0-4 Remaining time of program step monitoring screen,” “0-5 Number
of pattern executions monitoring screen,” or “0-6 Execution PID No. monitoring screen”), the mode automatically returns to
the “0-0 Basic screen” of screen group 0 (auto return).
5-5. Screen group 0 setting
The flow is given in “6. Screen explanation and setting items.” This section however primarily contains a description of how
to make settings.
As for the key operation method, the Å key switches to the next screen. The settings are selected with the Ģ key or ġ
key on the various setting screens and entered with the ģ key.
Pressing the ģ key is however not required for modifying output values on the output monitoring screen for manual
adjustment.
(1) Setting target set values (SV)
1.

To set target set values (SV), press the Ģ key or ġ key on the “0-0 Basic screen.” Pressing and holding the key
causes all SV lamps to flash, and the value is incremented or decremented. When the desired target set value is reached,
enter by pressing the ģ key.
2. When the setting is entered, the SV lamps of the target set value stop flashing. Target values cannot be set while auto
tuning (AT) is being executed. To set target values, you must first cancel auto tuning.
Example: Set target set value to 500°C.

screen” or press the ģ and Ģ keys simultaneously.
During manual output, the MAN lamp flashes and it goes off during the automatic output operation.
Pressing the Ģ key or ġ key on the output monitoring screen during manual output enables you to set the manual
output values.
To return to automatic output, press and hold the ģ key at least 3 seconds or press the ģ and Ģ keys simultaneously.

1. If output value is 100.0%, ©q{q is displayed on the output monitoring screen and the decimal point of © flashes.
2. If output is contact or SSR drive voltage and the proportional band (P) setting is OFF, the output value is 0.0% or 100.0%.
3. If output is voltage or current and the proportional band (P) setting is OFF, the output value is the lower limit value or
higher limit value of the output limiter set.
Note 1: Manual output cannot be selected while automatic tuning (AT) is being executed. To select manual output, you
must first cancel AT.
Note 2: If MAN is selected in “4-13 DI mode setting screen,” external control input (DI) has a priority and manual output
change cannot be conducted in 0-2 screen.
2) Supplementary explanation for use of manual control output
The correlation of the “0-2 Output monitoring screen” and automatic/manual output is as follows:
1. Output when automatic output is changed to manual is balanceless bumpless action, and the output value prior to the
change is displayed. When manual is changed to automatic, it becomes bumpless action except if measured value (PV)
is outside the proportional band.
2. If power supply is cut off and turned back on, control output action continues in automatic or manual mode, whichever
was set when the power was shut off.
Note: You can switch to another screen in the manual mode as well, but you should note that control output is also
manual mode. When the MAN monitor LED is flashing, the controller is in manual output mode (MAN).
3. Manual output (MAN) is canceled if RUN is switched to RST.
MAN operation is possible only in RUN mode.
