Entering Data
Set Keys
The keys in this group are used to modify or review settings of the pumps control data. To
review the current setting of a control data item, simply hold down the
relevant key and the data setting will appear in the display.
To modify a data setting, first press then release the green SET key. The display will then read
“SET”. Press the key in the SET key group of the data item that is to be modified. The display
will show the current setting. Data is entered into the pump by either entering a numerical
value or, in the case of entering a baud rate, by scrolling through a menu of choices. Always
press ENTER to terminate each data request by the pump.
When entering a numerical value, the LEDs corresponding to the data being entered will
blink. Using the yellow data entry keys on the right side of the keypad (see Figure 3) enter
the new data value. Up to five digit numbers are accepted for rates and diameters, including
up to four decimal places. Entering more than five digits will clear the previous five digits in
the display. Press the green ENTER key when the desired data value is displayed.
If the data value entered is outside the pump’s operating parameters, the display will read
“oor” meaning “Out of Range”. Pressing any key will restore the display with the original
data value. Enter another data value within the pump’s parameters or just press ENTER to
reuse the original data value.
The data value entered can be reviewed as described above. Note: Certain data items have
multiple settings. For these, after the ENTER key is pressed, the display will prompt you for
the additional information. Various rules apply to when, what and how data can be set at
various times. See the relevant section for further details.
Toggle Keys
The keys in this group, when pressed successively, select different states. Each state change is
accompanied by a corresponding change in status LED display.
To operate, Pump 33 needs to know the diameter(s) of the syringes, the rate(s) of pumping,
pumping directions, and the mode of operation. Except for Proportional mode, syringe 2 is
assumed to be the same diameter as syringe 1 and will pump at same rate as syringe 1.
