▒ Control operation direction
Set a control operation at the SL9.
① 0 : Reverse operation for heating control
② 1 : Direct operation for cooling control
▒ Input filter
Select the input filter calculation time in SL11. The input signal may
have noise that can be a cause of fluctuation of the process value. This
function eliminates the fluctuation by displaying the calculated value in
preset time. When 「0」 is set, the input filter is turned OFF.
▒ Input scale
Set a range of input voltage for DCV input.
For instance, SL1 = 0000 (1~5 V DCV) input, SL12 = 100.0, SL13 = 0.0
will be displayed as below.
▒ Alarm delay time
Set high and low alarm delay time at SL14 and SL15 respectively. Even
when alarm condition is met, if delay is set at SL14 and SL15, the
alarm is triggered after those settings are exceeded. However, alarm
off is not related to the delay setting.
▒ Anti reset wind-up
Set the anti reset wind-up with “A” parameter.
① Control in case of A = Auto (0)
② In case of a set value for temperature on “A” parameter.
※
If “A” is too small, large overshoot or undershoot occurs. Set the value
the same as the proportional value.

▒ Auto-tuning (AT) function
The Auto-tuning function automatically measures, computes and set
the optimum P. I. D and ARW constants, The Auto-tuning function is
activated any time from any process states after power-on, while
temperature is rising and or when control is stabilized.
● After finishing settings other than PID and ARW, perform the Auto-
tuning operation.
● Press the key and key at the same time then, A. T indication
lamp flashes to start the Auto-tuning function.
● If Auto-tuning function ends, the A. T indication lamp stops flashing
automatically. When checking the auto-tuned value, press the key .
● When changing the constants automatically set by the Auto-tuning,
changes each constant according to each parameter setting
● When you want Auto-tuning function to be suspended, press the
key and key simultaneously, then the A. T indication lamp
stops flashing to release Auto-tuning function. In this case P. I. D and
ARW values are not changed (Maintain the value before the Auto-
tuning started)
● When you want to changes the SV (set-value) during Auto-tuning,
suspend it and perform PID control using the values before Auto-
tuning started.
▒ Set data lock function
The set data lock function is used to prevent changing of each set-
value by the front key and the activation of the auto-tuning function, i.e.,
prevent misoperation after setting has ended.
For set data lock, display by pressing the key, then set the
following value in accordance with setting procedure thereby enabling
data lock ON or OFF.
0000 : No set data locked.
0001 : Only set-value (SV) can be changed with the set data locked.
Setting other than the above locks all set date and A.T function.
※ Each alarm operation can be set as shown below.
(▲: Set-value (SV) △: Alarm set-value)
▒ Overscale and underscale
● If a process value exceeds the maximum temperature range due to
upscale (input break) or etc., the process value (PV) display unit
flashes overscale display 「“”」
● If a process value reaches below the minimum temperature range,
the process value (PV) display unit flashes underscale display
「“”」
Note) Regardless of the set-value, the high or low alarm is activated at the alarm set- value.
※ For the band alarm, the relay of the low alarm (ALL) is not activated but the relay of the
high alarm (ALH) is activated.

Input type
This alarm setting is that the alarm is activated if a few ℃ is higher or low than set-
value. For example, if the set-value of the temperature is 200 ℃ and a system is
designed to have that the high alarm (ALH) is activated when the process value is 205
℃ and the low alarm is activated when the process value is 190 ℃ then set the high
alarm (ALH) 5 ℃, and set the low alarm (ALL) 10 ℃. If the set-value is changed to 300
℃, the high alarm is activated at 305 ℃ and the low alarm is activated at 290 ℃.
