5.1 Entering Values
When applicable, values can be changed by either displaying the current value, then using the arrow keys,
or from a computer connected to the pump. 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. The
only exception is when the pumping rate is changed from an attached computer while the Pumping
Program is operating. In this case the new pumping rate will not be stored in non-volatile memory.
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 settings 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 (Liquid Crystal Diode) display. This is the general
purpose user display device for displaying numerical data, functions and parameters. The colon (:) is used
for displaying time or for separating function abbreviations from their parameter values. In the upper left
corner is a triangle that indicates valid reception of RS-232 remote communications.
5.3 LEDs
To the right of the LCD are 8 red, round, LED (Light Emitting Diode) 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.
‘Dispensed’ indicates that the displayed volume is the total ‘Volume Dispensed’ or pumped.
When ‘Pumping’ is lit (not blinking), the motor is operating, either infusing or withdrawing. If
blinking, the motor is not operating, and the Pumping Program is paused. When the pump is restarted, the
