2-3.5 DISPLAY

N o t i c e : This manual utilizes a gray rectangular box underlined in black to represent a blinking cursor in all illustrations of the programmer’s display (Figure 2-9).

A 2-line, 16-character per line liquid crystal display is used to display all trip unit data, setpoints and mes-

sages. The brightness of the display can be adjusted through the use of a small, recessed adjusting screw located in the top side of the programmer (Figure 2-2).

The first line of the display is normally used to show the main menu selection possibilities. A blinking cursor indicates which category on the first line is active. The second line of the display either defines the first line category highlighted by the blinking cursor or, in lower level menus, presents a field that is capable of being changed, as indicated by a blinking cursor. Note in Figure 2 - 9 t h a t the blinking cursor is positioned just to the left of S A i n the top line of the display. Note also that the second display line defines that category as Select Address. Table 2 . 1 outlines all the displayed menu items that can be encountered in the OPTIMizer display along with their specific definitions. Figure 2 - 1 1 shows the twelve available options accessible from the main menu.
