6.3. Controller with Display

Refer to Figure 6.3-1 for the front panel layout. The keypad consists of five buttons: , , ↵

(Enter), ESC (Escape) and “?” or Help key. The displays available consist of selection menus,

informational displays and editable displays.

Selection Menus – permit the display of multiple items. The up and down keypads allow the user

to scroll up and down among the selections. The item indicated by the right carrot is the pre-

selected item. The ↵ selects the function and the display changes to that item. The ESC keypad

will take you back to the previous menu.

Information displays – display power plant information in a preformatted display. The information

is dynamic.

Editable Displays

– permit the change of certain parameters within the power plant. The PIN or

password will need to be entered before parameters can be changed. Once the PIN is entered

it will not be required to be entered a second time that session. The up, down and enter keys

are used to modify the value.

The screen will revert to the language selection screen after a controller reset. Choices are

English and Chinese.
