4.20 Simultaneous Temperature Rise Function
(d) When auto tuning is started with the temperature process value (PV) within the
stable judgment width (1°C ( )) after the setting mode is changed to the operation
mode
Until the temperature process value (PV) goes outside the stable judgment width (1°C ( )), the data
measured after the module is shifted to the operation mode (Setting/operation mode instruction (Yn1) is turned
off and on) can be used. Therefore, the simultaneous temperature rise parameter can be calculated with auto
tuning.
