15.1 Keypad functions in menu screens
In addition to their functions in other operations, the following keys have specific ac-
tions in menu screens:
STOP
: In general,
STOP
functions as a “go back” key, taking the user up one
menu level without making a change.
UP
: The
UP
key is used in menu item selection: it moves a highlight up the
menu. When a numerical entry screen is displayed, pressing
UP
increases the
number displayed.
DOWN
: The
DOWN
key is used in menu item selection: it moves a highlight
down a menu. When a numerical entry screen is displayed, pressing
DOWN
de-
creases the number displayed.
ENTER
: The
ENTER
key functions in a similar way to the “enter” key of a per-
sonal computer: it confirms key-presses made immediately before. In menu
item selection, it triggers the action or display selected from a menu using the
UP
and
DOWN
keys.
Note
: Confirmation screens are displayed for 4 seconds. While they are displayed, a
single press on any key removes them.
15.2 Main menu entry
The
MENU
key displays the main menu and stops the pump if it is running in Man-
ual mode. It operates at any point in the pump’s activity except where error screens
are displayed, where
UP
and
DOWN
keys are used to enter values, or where a PIN
is requested.
The main menu offers four options:
Setup, MemoDose, Pin out details,
and
Exit.
Use the
UP
and
DOWN
keys to make a choice. Press the
ENTER
key to confirm your
decision.
Setup
Setup
allows the user to set the pump’s operating parameters under 15 headings:
Trim, Analogue, Display, Outputs, Remote stop, Auto-restart, Set max speed, Set min
speed, Scrolling, Date/time, Backlight, ROM, Language, Defaults, Security code and
Exit.
MemoDose
The
MemoDose
facility is used to remember the number of revolutions needed to
dispense a previously dispensed volume of fluid, and cause the pump to dispense
that volume repeatedly.
