5.1 Entering Values
When applicable, values can be changed by displaying the current value, then using the arrow keys. The
new value will be stored in the pump’s non-volatile memory, meaning that the new value will not be lost
the next time that power is applied to the pump.
A displayed value can be changed by pressing the arrow keys below each digit. If the value to be changed
is not currently displayed, when applicable, press the key associated with the required value. The display
will show the setting’s current value and its units, if any.
While the current value is being changed, the units LEDs associated with the value, if any, will blink.
Except where noted, the new value is stored, and/or the selected operation takes affect, when either
1) A non-arrow key is pressed or
2) After a 2 second delay since the last arrow key was pressed.
If the new value is valid and different from the original value, the display will blink, indicating that the
new value was stored. Otherwise, if the value was invalid, an error message will be displayed. Pressing
any key clears the error message and restores the original value.
In general, if a parameter has 2 values, ‘off’ and ‘on’, they are represented by the numbers ‘0’ and ‘1’,
respectfully.
5.2 LCD Display
The display consists of a 4 digit reflective LCD display. This is the general purpose user display device
for displaying floating point values, functions and parameters. The colon (:) is used for separating
function abbreviations from their parameter values.
5.3 LEDs
To the right of the LCD are 8 red, round, LED indicators. The first 2 columns display the units of the
displayed values. Units are expressed using 1 or 2 LEDs. For instance, ‘ml / hr’ is expressed by lighting
the ‘ml’ and the ‘hr’ LEDs.
