B.10 Control
Menu
The user may request basic features such as HPA states, Control modes, and Fault Recycle
modes directly using front panel buttons. Most HPA features, however, require a more
sophisticated user interface. To provide logical access to this information, these special HPA
features are grouped into categories. Categories and associated functions are shown on display
Lines 3 and 4. To provide an orderly user interface with the front panel, the various HPA
features, settings, and controls are grouped according to the following hierarchy:
Category
—Top-level group
Function
—Data entry or data display selection within a category
Entry
—Data entry or data review within a function
Access to the hierarchy is as follows:
Category
—Press the MENU button to toggle through the accessible categories. Category names
appear on Line 3.
Function
—When the
t
symbol appears next to
a category, press the FUNCTION
button to toggle through the accessible functions (viewed on Line 4) under that category.
