The related display call-up buttons are composed of six sets of display call-up buttons.

If the operator clicks one of the six buttons, the indicated display will be called up and activated. If a button with blue text is clicked, the related group display will be called up and activated.

4.3.2.1.4 File Name Display

This window displays the file name of the active custom display. The “MAIN”

pushbutton will open the Main index page.

4.3.2.1.5 Alarm window

The alarm window displays the two latest process alarms.

The red colored alarm priority indicator will flicker until the operator has acknowledged the alarm.

The alarm priority indicator will have a gray background if the PV is returned to normal value on an unacknowledged alarm

4.3.2.1.6 Alarm acknowledge button

Alarms visible in the alarm window may be acknowledged directly from the graphic window by pressing the <ACK> button on the keyboard or the red

“ACK” button in the Alarm display zone. Other alarms must be acknowledged from the Alarm summary window

4.3.2.1.7 Alarm summary button

The alarm summary window can be opened by clicking the “ALM” button.

This button will also indicate unacknowledged alarms.

4.3.2.2 Process Graphic Zone

The operator can monitor the process value and the present status of the local equipment at the process graphic zone. Points for presentation or operation can be selected here with the trackball buttons.

4.3.2.3 Change Zone

The change zone is used for performing actions like start/stop of motors, opening and closing of valves, changing between auto and manual, etc.

A faceplate appears in the change zone when a point is selected with the left trackball button. The faceplates used in the change zone are custom made for each kind of operation. A closer description of each faceplate can be found under 4.3.3 “Operational procedures”. The change zone can be hidden by clicking the 'CLR' button at the right part of the zone.

4.3.3 Operational procedures 4.3.3.1 Motor operation

4.3.3.1.1 Operation from change zone.

When a motor symbol is selected using the left trackball button, the motor operation faceplate will appear in the change zone. The faceplate contains 'START' and 'STOP' pushbuttons. If the motor has a stand-by start function, the faceplate will contain 'START' and 'STOP' buttons for both motors in the stand-by set. There will also be buttons for 'SET' or 'CANCEL' of the stand-stand-by function. Further details may be found by pushing the button with the channel number which will open the native window.

In addition, there is a 'Detail' pushbutton. Clicking this will open a small pop-up window with one or more points. Selecting a point here and then clicking 'OK' will open the native window with details for the selected point.

4.3.3.1.2 Operation from pop-up window

If a motor symbol is selected using the right trackball button, a pop-up window will appear close to the selected motor. The pop-up window will contain only start/stop buttons. When a button has been pressed, action will take place immediately, and the pop-up window will automatically close. If the selected motor has a standby start function, the pop-up window will contain start and stop buttons for both motors of the standby set. Standby selection and canceling cannot be done from the pop-up window; it must be done from the change zone.

4.3.3.2 Valve operation – hydraulically operated throttling valves

4.3.3.2.1 Operation from change zone

When a throttle valve symbol is selected using the left trackball button, the throttle valve faceplate will appear in the change zone. The faceplate contains buttons for 'Full OP' and 'Full CL'. If applicable, buttons for selection between 'AUTO', 'MAN' and 'CAS'(cascade) will also appear. When the valve is in manual mode, the operator may press the 'OP' (Output) button and push the increase (up arrow)or decrease (down arrow) button on the operating keyboard to manipulate the valve. If the valve is in auto mode, the operator can press the 'SP' (set point) button and type the desired value in the small field that opens.

Pressing <ENTER> will start the action.

If a valve is in ‘CAS’ (cascade) mode, this valve’s opening setpoint will be changed by the primary controller’s output. In this mode, the operator cannot adjust the secondary controller. For example, when a cargo pump discharge valve is in ‘CAS’ mode, the operator can only adjust this valve with the cargo pump’s load controller which in turn will control the valve automatically.

4.3.3.2.2 Operation from pop-up window

When a throttle valve symbol is selected using the right trackball button, a pop-up window will appear close to the selected valve. The pop-pop-up window will contain 'Full OP' and 'Full CL' buttons, and a field for typing the desired opening in percent. To give percent opening, the operator can use the keyboard to type the wanted value, and then press <ENTER>. If the valve’s control mode is ‘AUTO’, the valve will start moving and the pop-up window will close automatically.

If the valve is in ‘MAN’ mode, a pop-up window with ‘Current mode is not Auto mode’ will appear and the operator must change to ‘AUTO’ in order to complete the operation.

4.3.3.2.3 Operation from keyboard

The operator keyboard may also be used for opening and closing of throttle valves.

When the valve is in ‘MAN’ mode, the operator may press the ‘OP’ button in the change zone on the graphic display or on the operating keyboard and push the increase or decrease button on the operating keyboard to control the valve.

Pressing the left side button with a single arrow will energize the solenoid valve for 0.02 sec per one push.

Pressing the right side button with double arrows will energize the solenoid valve for 0.1 sec per one push.

When the valve is in 'AUTO' mode, the operator may press the 'SP' button in the change zone on the graphic display or on the operating keyboard and push the increase or decrease button on the operating keyboard to manipulate the valve.

Pressing the left side buttons with a single arrow will raise/lower the SP value 0.1% of the range per push.

Pressing the right side buttons with double arrows will raise/lower the SP value 2% of the range per push.
