5. PRECAUTION OF PROGRAM DRIVE
・This unit can select the type of Input. The input type of Thermocouple can be selected from K, J, T, R, N and B. Also,
the input type of R.T.D can be selected from Pt100 and JPt100.
At actual usage, the initial setting of input type at this unit is desperately needed.
For the setting of input type, please refer to "6.TYPE OF INPUT/OUTPUT" of "f) COMMON PARAMETER SETTING
MODE". In case B Thermocouple is selected, the setting range below 399℃(750
) is out of Instruction/Setting accuracy
range of this unit.
CAUTION
・In case of selection of Input type, the initial setting of input type at this unit is desperately needed.
・In case B Thermocouple is selected, do not control program below 399℃(750
).
This unit is able to control several types such as ON/OFF control, PID control and PID + Fuzzy control.
The setting of Input type should be done as per "5.TYPES OF CONTROL" of "f) COMMON PARAMETER
SETTING MODE". The parameter for control is independently separated by Low Temperature Area, Middle
Temperature Area and High Temperature Area, therefore, please make setting of each Control Temperature area. Also,
please make setting of other control parameter as required.
The setting of Key Input is valid in memory even if the power turned OFF.

Initial Value of control sensitivity of this unit is set "0". Please alter the setting as required.
By setting the sensitivity, the point of ON and OFF can be differed.
The position of OFF point is the target Setting Value(SV) as shown below.
The deviation between the target Setting Value(SV) and the sensitivity Setting Value becomes ON position.
