Navigation Pushbuttons (Cont.)
PAGE BUTTON
From any non-configuration page, pressing this push button causes the top level menu (figure 1.1.2) to
appear. The figure shows the menu for a user logged in with ‘Engineer’ level access. Other access levels
may have fewer menu items.
Within configuration pages, the Scroll button can be used as an enter key to select lower menu levels. In
such cases the page button is used to reverse this action, moving the user up one menu level per
operation.
SCROLL BUTTON
From trending pages, operation of the scroll push-button scrolls through the channels enabled in the
group. The Faceplate cycling ‘Off’ selection can be used to keep a particular channel permanently
displayed, and the scroll pushbuttons can then be used to select channels manually.
In configuration pages, the scroll key operates as an ‘enter’ key to enter the next menu level associated
with the highlighted item. Once the lowest menu level is reached, operation of the scroll key allows the
value of the selected item to be edited by the relevant means (for example, the raise/lower keys, or a
keyboard entry).
The ‘Page’ key is used to move the user back up the menu structure, until the top level menu is reached,
when the scroll key can be used again to return to the Home page.
The scroll button is also used to initiate user wiring as described in Section 7
RAISE/LOWER BUTTONS
Within trending displays, the Raise and Lower keys can be used to scroll through the enabled display
modes in the sequence: vertical trend, horizontal trend, vertical bargraph, horizontal bargraph, numeric,
vertical trend... and so on.
Within configuration pages, these pushbuttons act as cursor keys, allowing, for example, the user to
highlight menu items for selection using the scroll button, and in many cases allowing the user to select
one from a number of alternative values within menu items. These keys are also used to navigate through
the virtual keyboards and number pads used to enter text or numeric strings.
4.1.3 On Screen Help
The top level configuration menu includes contextual help text on the right-hand half of the screen.
Mostly this text fits within on screen height. Where this is not the case, the text can be moved up or down
the screen by holding the Page button operated whilst using the up and down arrows to move the text.
The down arrow moves the text upwards on the screen; the up arrow moves it downwards.
