14 Manual operation
14.1 Keypad functions
All settings and functions of the pump in manual mode are set and controlled by
means of key-presses. Immediately after the start-up display sequence detailed
above, the manual mode main screen will be displayed. The currently selected rota-
tion direction is indicated on the display by a clockwise or counter-clockwise seg-
mented arrow. If an exclamation
mark (
!
) shows, it indicates that
Auto-restart is on (see 14.8
Auto-
restart
). If a padlock icon (
)
shows, it indicates that Keypad lock
is on (see 14.4
Keypad lock
).
Note
: A number of the controls
listed below are shortcuts to com-
mands which are also available
through the Main menu. See 15
Main menu
.
Note
:
SHIFT
gives access to func-
tions which appear on the upper
part of numeric keys. To access the
MAX
function, for example, press
SHIFT
once
and release it
. A symbol appears in the bottom left of the display to
indicate that the next keypress will be
SHIFT
ed. Press
4 (MAX)
.
A brief single press on each key triggers a beep sound (if enabled - see 14.5
Keypad
beep
) and causes the pump to function as follows:
START
: starts the pump at the speed and in the direction shown on the dis-
play. The rotation symbol will become animated to confirm that the pump is
operating.
If the pump is running when
START
is pressed, it causes the information
shown on the manual mode main screen to cycle from revolutions per minute,
to flow rate in a choice of units (via a warning screen if flow rate has not been
calibrated and if this is the first cycle since power-up) to rpm, flow rate, cumu-
lative volume and Run time. An example is shown here. The default can be
altered from within the Setup menu (see 18.3
Display
).
