Operation 2604 Controller3. Chapter 3 PRINCIPLE OF OPERATIONThis chapter explains how to locate and change the value of parameters using the front panelbuttons. Operation of these buttons changes the display view by bringing up different pages.The pages and the location of parameters within these pages follows a set order. This chapterdescribes how to navigate between the pages.Note: The 2604 controller is an application specific controller and can be configured tothe preferences of a particular process, site or even user. This means that the displaysshown in this and following chapters may not be identical to those shown in yourinstrument. Where the text on a display is user configurable it is shown in italics, egLoop1About this chapterThis chapter describes:◊ How to change setpoint◊ The operator buttons◊ Parameters and how to access them◊ Pages◊ How to step through pages◊ How to step through parameters◊ How to change parameter values◊ The navigation diagram◊ Parameter tables3-2 User Guide Part No HA026491 Issue 3.0 Apr-02
2604 Controller Operation3.1. POWER UPInstall and wire up the controller in accordance with Chapter 2 and switch on. A short self testsequence takes place during which the controller identification is displayed together with theversion number of software fitted.3.1.1. The HOME PageThe controller then shows a default display, referred to as the HOME page. It is possible tocustomise all three readouts of this display but the format is shown in Figure 3-2. It is also thedefault display on a new controller.The HOME page will be displayed under the following conditions:-1. When the controller is switched on2. When the access mode is changed from configuration level to a different level3. When and are pressed together (see 3.10)4. When a timeout (if configured) occursThe upper and middle readouts can be configured to display any available parameter but thedefault is Process Variable and Setpoint respectively.The lower readout can be configured to show:-1. Loop Views - LP1 to LP3 as shown2. The Access page (see Chapter 4)3. The Summary page (see Chapter 5)4. The Run page (see Chapter 6)5. Cycle each loop. LP1 to LP3 pages are cycled in turnThe configuration of these displays is described in the Engineering manual, Part No.HA026761.Alarm BeaconSee Figure 1-4Standby ModeSee Figure 1-4LED statusindicators (seeFigure 1–4)Upper Display - (usually indicatesProcess Variable but can becustomised)Middle Display - (usually indicatesSetpoint when in Auto or OutputPower when in Manual but can becustomised)Lower Alpha/Numeric LCDDisplay (usually indicatesmessages)Operator buttons (see Figure 3-2)Figure 3-1: The ’HOME’ Page (default)User Guide Part No HA026491 Issue 3.0 Apr-02 3-3
