Hysteresis range for ON/OFF control (Setting range: 0 to 50%FS)[Description]• To select the ON/OFF control (two-position control), setto 0.0. It is not necessary to set and .• When the hysteresis range (Range of ON/OFF control) istoo small, the output may switch the ON/OFF frequently.(This may affect the life of the device to be controlled,especially when contact output is selected.)• The unit of the set value of this parameter is ºC or ºF(engineering unit). The setting range varies according tothe measured range of input.[Ex] Input Thermocouple K : At measured range of 0to 400 ºC, the settingrange is 0 to 200 ºC.Resistance bulb : At measured range of 0to 150 ºC, the settingrange is 0 to 75 ºC.Related parameters: (page 20)(page 32)[Setting example] Changing the hysteresis range from 1˚C to 35˚CDisplayPV 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 35˚C will be registered for . After that,the controller will operate with the being 35˚C.(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.23
