13 Switching the pump on
in subsequent power cycles
(if not in auto-restart mode)
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 26.1 Error codes.
The pump displays the Watson-Marlow start-up screen for four seconds
followed by the pump model identity screen for four seconds, and then the
manual mode main screen.
Note: Once in the manual mode main screen, keys assume their normal func-
tions - see 15.1 Keypad in menu screens below. A subsequent press on START
causes the pump to operate.
Start-up defaults are those in place when the pump was switched off last.
Check that the pump is set to operate as you require it.
The pump is now ready to operate.
