This unit uses a fixed memory device to memorize setting value. Therefore, the setting value remains in memory even after
Power Off. At actual selection, please arrange to match the kind and initial setting of the sensor.
For the setting of input kind, please refer to "Kinds of Input/Output in Parameter Display ". This unit is able to７
control 2 types such as ON/OFF control and PID control(Time Proportional Control).
PID CONTROL Advantage : Better result of control compared with ON/OFF Control.・
Disadvantage: The life period of relay contact becomes short as it switches On and OFF so frequently.
ON/OFF CONTROL Advantage : Generally, the life period of relay contact last longer as it switches ON at temperature・
increase and OFF at temperature decrease from the level of setting value.
Disadvantage: The result of control is not as good as PID Control.
As for the Setting of t he KIND OF CONTROL, please select and set at the display of "KIND OF CONTROL"of
"PARAMETER DISPLAY ".・10

better result of control. While Auto-tuning is operational stabilize the fluttering.

At the time of Auto-Tuning, set the unit to the condition
of actual control by connecting heater and sensors.
It may take a time to finalize Auto-tuning.
For start of Auto-tuning, please press key for more▲
than 2 seconds at AT Start Display of Mode Display "."E
After start up, Auto-tuning and Parameters Setting
will be done automatically, and the control is to be
started soon.
Due to the above procedure, the parameter can be set to match the unit to be controlled.
