14 Manual operation
14.1 Keypad functions in manual mode
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 rotation direction is indicated
on the display by a clockwise or count-
er-clockwise segmented arrow. If an
exclamation mark (
!
) shows, it indi-
cates that Auto-restart is on (see 18.12
Auto-restart
). If a padlock icon (
)
shows, it indicates that Keypad lock is
on (see 14.2
Keypad lock
).
Note
: A number of the controls listed
below are shortcuts to commands
which are also available through the
Main menu. See 15
Main menu
.
A brief single press
on each key trig-
gers a beep sound (if enabled - see
14.3
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. We recommend that the speed is reduced to a minimum (0.1 rpm)
before starting the pump.
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 flowrate in a choice of units (via a warning screen if flowrate has not been
calibrated and if this is the first cycle since power-up) to rpm, flowrate and Run
time. An example is shown here. (See
START
, above. See 17
Calibrate
. See
18.9
Run time
.) This cycle operates when the pump is stopped and when it is
running. The default can be altered from within the Setup menu. See 18.3
Display
.
