Unit Controller Operation
The unit controller HMI/display is an 8-line display with 6 buttons
(keys). The right side buttons are used for navigation of the
menus with up, down, and check/enter. The Up and Down
buttons move the cursor up and down the screen. If the selected
line links to another screen, there will be an arrowhead on the
right end of the line. To navigate to the linked screen, the Enter
button is pressed.

Menu Details
Three types of lines exist:
• Menu title, displayed in the rst line as in Figure 29.
• Link (also called Jump) having an arrow ( > ) in the right of
the line and used to link to the next menu.
• Parameters with a value or adjustable set point.
The rst line visible on each display includes the menu title and
the line number indicating which menu number you are on and
the total number of menus. In the above menu screen, the title is
Cir 1 Data and it is menu 1 of 22.
Figure 29: Example Menu Screen
The right most position of the title line includes an “up” arrow ▲
to indicate there are menus (parameters) “above” the currently
displayed line; and/or a “down” arrow ▼ to indicate there are
menus “below” the currently displayed items or an “up/down”
arrow to indicate there are lines “above and below” the currently
displayed line.
Each line on a screen can contain status-only information
or include changeable data elds (set points) and becomes
highlighted when the cursor is on that line. A line in a menu may
also be a link to further menus. An arrow is displayed to the far
right of the line to indicate it is a “jump” line, meaning pushing
the bottom right checkmark button will cause a “jump” to a new
menu.
