The keypad/display consists of a 5-line by 22 character display,
three keys and a “push and roll” navigation wheel. There is an
Alarm Button, Menu (Home) Button, and a Back Button. The
wheel is used to navigate between lines on a screen (page)
and to increase and decrease changeable values when editing.
Pushing the wheel acts as an Enter Button.

The rst line on each page includes the page title and the line
number to which the cursor is currently “pointing”. The line
numbers are X/Y to indicate line number X of a total of Y lines
for that page. The left most position of the title line includes an
“up” arrow to indicate there are pages “above” the currently
displayed items, a “down” arrow to indicate there are pages
“below” the currently displayed items or an “up/down” arrow
to indicate there are pages “above and below” the currently
displayed page.
Each line on a page can contain status only information or
include changeable data elds. When a line contains status
only information and the cursor is on that line all but the value
eld of that line is highlighted meaning the text is white with
a black box around it. When the line contains a changeable
value and the cursor is at that line, the entire line is highlighted.
Each line on a page may also be dened as a “jump” line,
meaning pushing the navigation wheel will cause a “jump” to
a new page. An arrow is displayed to the far right of the line to
indicate it is a “jump” line and the entire line is highlighted when
the cursor is on that line.
The keypad/display Information is organized into Menu groups;
Main Menu, Quick Menu, View/Set Unit Menu, Commission
Unit Menu, Manual Control Menu, Service Menu, Unit
Conguration Menu and Alarm list Menus.
NOTE: Only menus and items that are applicable to the
specic unit conguration are displayed.

Set Unit Menus include basic menus and items required to

Menus include more advanced items for “tuning” unit operation
such as PI loop parameters and time delays. The Manual
