12 Switching the pump on
for the first time
Note: This manual uses bold type to highlight the active option in menu screens:
“English” in the first screen represented here. The active option appears on the
pump display in
inverse text.
Switch on the power supply at the rear of the pump. The pump runs a power-
on test to confirm proper functioning of the memory and hardware. If a fault is
found, an error message is displayed. See 23.1 Error codes.
The pump displays a language menu. Use the UP and DOWN keys to select
your language. Press the ENTER key to confirm your choice.
The information which follows assumes that your choice was English.
When the language is chosen this menu will not appear again and all menus
will appear in the language you chose. (Language can be reset as described
later. See 16.13 Language.)
The pump displays the Watson-Marlow start-up screen for four seconds, fol-
lowed by the pump model identity screen for four seconds (an example is
shown here), and then the manual mode main screen.
The rotation symbol on the display indicates clockwise rotation. The default
speed setting is 165rpm, but 265rpm is available (see 16.7 Set maximum
allowed speed). Other initial start-up operational parameters are listed in the
table below.
