PV (Measured value) stable range (Setting range: 0 to 100%FS)[Description]• Self-tuning logic recognizes that control is stable if PV isstaying within the SV ± .• It is not necessary to set this parameter under normal conditions.[Setting example] Changing the PV stable range from 2 to 3DisplayPV indicationSV indicationPV indication1.2.3.4.5.6.Press and hold the SEL key for three seconds.will be displayed.Press the key to display .Press the SEL key once.The current setting ( ) will be displayed.Operating procedurePress the or keys to flicker and to display .Press the SEL key once. will be displayed and 3 will be registered for . After that,the controller will operate with the PV stable range being 3.(Repeat the procedure from 3 to 5 to check the set value.)If you want to display the operation status, press and hold the SEL key for two seconds.The SV will be displayed on the display area.If unoperated state continues, the PV will be displayed.31
