P ART 3 OPERA TION: CONFIGURA TION MODE 3.1 Introduction The instrument has two different modes of operation. The first, Run Mode, is used to display values for the Process V ariable, and to display or clear Peak and V alley values. The other mode, Menu Configuration Mode, is used to navigate through the menu options and configure the controller .
3.2 Menu Configuration It is required that you put the controller in the Standby Mode for any configuration change other than Set Points & Alarms. Figure 3.
