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 25.1 Error codes.

￿The pump displays the Watson-Marlow start-up screen for four seconds fol- lowed by the pump model identity screen for four seconds, and then the manu- al mode main screen.

￿Note: If ANY key is pressed during the display of any of the preliminary screens, the display jumps to the next screen. Quickly pressing any two keys or any key twice immediately after switch-on causes the display to jump to the manual mode main screen. Once in the manual mode main screen, keys assume their normal functions - see 15.1 Keypad functions in manual mode 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.

All operating parameters may be changed by means of key-presses. See 14 Manual operation.
