￿Press the STOP key twice within half a second to return to MemoDose. The dis- play shows the previous percentage dose size. The pump will dose at the new speed.

Note: To retain the MemoDose value through a power interruption the pump must be in auto-restart mode. The dosing cycle will resume at the start of a dose and wait for START to be pressed, with the MemoDose percentage screen displayed. See

18.12Auto-restart.

20.2Footswitch operation and other remote inputs and outputs with MemoDose

A footswitch or a momentary contact switch can be used to trigger MemoDose dispensing as a hands-free alterna- tive to pressing START.

To install a footswitch, connect it between the +5V termi- nal and the i/p terminal of the Dose input connector (J3). Alternatively a logic signal of between 5V and 24V can be applied to the i/p terminal of the Dose input connector (J3), ground to the OV terminal.

To operate MemoDose with a footswitch, briefly press the footswitch while the MemoDose percentage screen is dis- played.

The remote run / stop input is operational. If a dose is interrupted by a remote stop signal, the dose will continue from where it stopped when the state is changed to run.

Remote direction control is disabled. The leak-detection input is operational. All sta- tus outputs are operational.

Note: The keypad lock feature is particularly useful to prevent inadvertent dose changes while using the MemoDose facility. Keypad lock continues to operate in MemoDose if previously enabled; it can also be enabled while in MemoDose mode. See 14.2 Keypad lock.
